Publication year: 2012Source:European Journal of ProtistologyChen Shao, Yan Ding, Khaled A. Al-Rasheid, Saleh A. Al-Farraj, Alan Warren, Weibo Song A marine hypotrich ciliate, Heterotachysoma multinucleatum (Gong and Choi, 2007) n. comb., found in coastal waters near Qingdao, China, was investigated. Heterotachysoma multinucleatum is characterized by its dorsal ciliature arranged in Gonostomum-pattern. Additionally, a new genus, Heterotachysoma n. gen., is established which is mainly characterized by: 18-cirri pattern; flexible body; three dorsal kineties with no dorsomarginal kineties nor kinety fragmentation; one right and one left row of marginal cirri; caudal cirri absent. The genus Tachysoma is redefined, and three new combinations, T. multinucleatum, T. ovatum and T. dragescoi, are proposed. The morphogenesis of Hemigastrostyla enigmatica (Dragesco and Dragesco-KernÃ©is, 1986) Song and Wilbert, 1997, is also described. Compared with that of its congeners, the differences are mainly in the dorsal ciliature: (1) the dorsal kinety anlagen are formed de novo in H. enigmatica (vs. intrakinetally in H. paraenigmatica and H. elongata); (2) the dorsal kineties anlagen develop in secondary mode in H. enigmatica (vs. primary mode in H. paraenigmatica); (3) the kinetal fragment anterior to the right marginal row in both filial product is absent in both H. enigmatica and H. elongata (vs. present in H. paraenigmatica). These findings suggest that morphogenesis is not uniform among members of the genus Hemigastrostyla.

Pseudocollinia brintoni gen. nov., sp. nov. (Apostomatida: Colliniidae), a parasitoid ciliate infecting the euphausiid Nyctiphanes simplex.

Pseudocollinia brintoni gen. nov., sp. nov. (Apostomatida: Colliniidae), a parasitoid ciliate infecting the euphausiid Nyctiphanes simplex. Dis Aquat Organ. 2012 May 15;99(1):57-78 Authors: Gómez-Gutiérrez J, Strüder-Kypke MC, Lynn DH, Shaw TC, Aguilar-Méndez MJ, López-Cortés A, Martínez-Gómez S, Robinson CJ Abstract A novel parasitoid ciliate, Pseudocollinia brintoni gen. nov., sp. nov. was discovered infecting the subtropical sac-spawning euphausiid Nyctiphanes simplex off both coasts of the Baja California peninsula, Mexico. We used microscopic, and genetic information to describe this species throughout most of its life cycle. Pseudocollinia is distinguished from other Colliniidae genera because it exclusively infects euphausiids, has a polymorphic life cycle, and has a small cone-shaped oral cavity whose left wall has a field of ciliated kinetosomes and whose opening is surrounded on the left and right by 2 'oral' kineties (or ciliary rows) that terminate at its anterior border. Two related species that infect different euphausiid species from higher latitudes in the northeastern Pacific Ocean, Collinia beringensis Capriulo and Small, 1986, briefly redescribed herein, and Collinia oregonensis Gómez-Gutiérrez, Peterson, and Morado, 2006, are transferred to the genus Pseudocollinia. P. brintoni has between 12 and 18 somatic kineties, and its oral cavity has only 2 oral kineties, while P. beringensis comb. nov. has more somatic kineties, including 3 oral kineties. P. oregonensis comb. nov. has an intermediate number of somatic kineties. P. beringensis comb. nov. also infects Thysanoessa raschi (a new host species). SSU rRNA and cox1 gene sequences demonstrated that Pseudocollinia ciliates are apostome ciliates and that P. brintoni is different from P. beringensis comb. nov. High densities of rod-shaped bacteria (1.7 µm length, 0.2 to 0.5 µm diameter) were associated with P. brintoni. After euphausiid rupture, high concentrations of P. brintoni and bacteria cluster to form 3 to 6 cm long filaments where tomites encyst and transform to the phoront stage; this is a novel place for encystation. P. brintoni may complete its life cycle when the euphausiids feed on these filaments. PMID: 22585303 [PubMed - in process]

Siansivirga zeaxanthinifaciens gen. nov., sp. nov., a novel zeaxanthin-producing member of the family Flavobacteriaceae isolated from coastal seawater of Taiwan. FEMS Microbiol Lett. 2012 May 14; Authors: Hameed A, Shahina M, Lin SY, Sridhar KR, Young LS, Lee MR, Chen WM, Chou JH, Young CC Abstract A strictly aerobic, Gram-negative, rod-shaped bacterium (strain CC-SAMT-1(T) ) showing gliding motility was isolated from coastal seawater of China Sea, Taiwan. Strain CC-SAMT-1(T) synthesizes all-trans-zeaxanthin (6.5 ± 0.5 mg g(-1) dry biomass) as a predominant xanthophyll carotenoid. As determined by 16S rRNA gene analysis, strain CC-SAMT-1(T) shared very high sequence similarity to the members of the genera Mariniflexile (96.1-95.3%) and Gaetbulibacter (96.0-95.9%); however, formed a distinct phyletic lineage distantly associated with Mariniflexile species. Polar lipid profile constitutes phosphatidylethanolamine, four unidentified amino lipids, four unidentified lipids and an unidentified glycolipid. Strain CC-SAMT-1(T) contains excessive unidentified amino lipid (AL2-4) and glycolipid contents, and therefore, clearly distinct from Mariniflexile species. Major fatty acids (>5% of total fatty acids) were iso-C(15:0) (14.8%), iso-C(17:0) 3-OH (11.8%), iso-C(15:1) G (10.6%), anteiso-C(15:0) (9.7%), C(16:0) (8.1%), iso-C(16:0) 3-OH (7.9%), iso-C(15:0) 3-OH (7.5%) and summed feature 3 (containing C(16:1) ω6c and/or C(16:1) ω7c) (7.5%). Menaquinone-6 (MK-6) was major respiratory quinone. DNA G+C content was 33.7 mol%. Based on polyphasic taxonomy, strain CC-SAMT-1(T) represent a novel genus and species in the family Flavobacteriaceae for which the name Siansivirga zeaxanthinifaciens gen. nov., sp. nov. is proposed. The type strain is CC-SAMT-1(T) (= BCRC 80315(T) = JCM 17682(T) ). © 2012 Federation of European Microbiological Societies. Published by Blackwell Publishing Ltd. All rights reserved.

Revision of two species of?Ulocrinus and a new pelecocrinid crinoid from West Timor

2012-05-17T13:09:12+01:00

Publication year: 2012Source:PalaeoworldG.D. Webster, Stephen K. Donovan Two cladid crinoid species,?Ulocrinus indicus Wanner, 1924, and?Ulocrinus conoideus Wanner, 1937, are reinterpreted as cladid crinoids that do not belong to the cromyocrinids. This justifies Wanner's questioning of the generic assignment.?Ulocrinus indicus has bifascial radial facets and is considered an advanced intermediate dendrocrinid assigned to the incertae superfamiliae, Katerocrinidae n. fam., Katerocrinus indicus n. gen., n. comb. This extends the range of the bifascial dendrocrinids upward into the Permian.?Ulocrinus conoideus has trifascial radial facets and is assigned to the superfamily Scytalocrinoidea, incertae familiae, Dochmocrinus conoideus n. gen., n. comb. It re-emphasizes the need for revision of the family Scytalocrinidae. An unnamed, poorly preserved cup is described and considered to be a pelecocrinid crinoid, thus adding to the diversity of the West Timor Permian crinoids.

Phylogeny and systematics of Melanesiaâ€™s most diverse gecko lineage (Cyrtodactylus, Gekkonidae, Squamata)

2012-05-17T13:09:09+01:00

Oliver, P.M., Richards, S.J. & Sistrom, M. (2012). Phylogeny and systematics of Melanesiaâ€™s most diverse gecko lineage (Cyrtodactylus, Gekkonidae, Squamata). â€”Zoologica Scripta, 00, 000â€“000.The systematics and biogeographical history of the diverse fauna of New Guinea and surrounding islands (Melanesia) remain poorly known. We present a phylogeny for 16 of the 21 recognised Melanesian bentâ€toed geckos in the genus Cyrtodactylus based on mitochondrial sequence data. These analyses reveal two divergent lineages of Cyrtodactylus within Melanesia. One includes a single recognised species with clear affinities to sampled taxa from Asia. The other comprises a relatively diverse radiation (likely 30+ species), not closely related to sampled extralimital taxa and centred on the Melanesian region (including Australia). Many taxa within this second lineage are endemic to islands surrounding New Guinea, and dispersal and speciation on peripheral islands appears to have played an important role in the accumulation of species diversity within this clade. In contrast, little diversity is centred upon montane areas, although we do identify at least one lineage closely associated with hill and lower montane forest that probably dates to at least the late Miocene. Our phylogenetic analyses also reveal numerous divergent lineages that require taxonomic attention, including at least two widespread taxa that are likely to be composite, additional specimens of Cyrtodactylus capreoloides (until recently known only from the holotype) and several divergent and completely novel lineages, two of which we introduce herein: Cyrtodactylus arcanus sp. n. and Cyrtodactylus medioclivus sp. n.

Amino acid-assimilating phototrophic heliobacteria from soda lake environments: Heliorestis acidaminivorans sp. nov. and 'Candidatus Heliomonas lunata' Extremophiles. 2012 May 16; Authors: Asao M, Takaichi S, Madigan MT Abstract Two novel taxa of heliobacteria, Heliorestis acidaminivorans sp. nov. strain HR10B(T) and 'Candidatus Heliomonas lunata' strain SLH, were cultured from shoreline sediments/soil of Lake El Hamra (Egypt) and lake water/benthic sediments of Soap Lake (USA), respectively; both are highly alkaline soda lakes. Cells of strain HR10B were straight rods, while cells of strain SLH were curved rods. Both organisms were obligate anaerobes, produced bacteriochlorophyll g, and lacked intracytoplasmic photosynthetic membrane systems. Although the absorption spectrum of strain HR10B was typical of other heliobacteria, that of strain SLH showed unusually strong absorbance of the OH-chlorophyll a component. Major carotenoids of both organisms were OH-diaponeurosporene glucosyl esters, as in other alkaliphilic heliobacteria, and both displayed an alkaliphilic and mesophilic phenotype. Strain HR10B was remarkable among heliobacteria in its capacity to photoassimilate a number of carbon sources, including several amino acids. Nitrogenase activity was observed in strain HR10B, but not in strain SLH. The 16S ribosomal RNA gene tree placed strain HR10B within the genus Heliorestis, but distinct from other described species. By contrast, strain SLH was phylogenetically more closely related to neutrophilic heliobacteria and is the first alkaliphilic heliobacterium known outside of the genus Heliorestis.

Publication year: 2012Source:Cretaceous ResearchMasaki Matsukawa, Samuel V. Sendon, Fe Tumanda Mateer, Tadashi Sato, Ikuwo Obata Nine Aptian to early Albian ammonoid species, apparently from the Yop Formation, in Catanduanes Island, Philippines, are described herein: Goretophylloceras sp., Eogaudryceras (Eotetragonites) sp., Notosilesitoides philippinensis gen. et sp. nov., Miyakoceras tanohatense, Neosilesites nepos, Neoastieria? sp., Marshallites miyakoensis, Colombiceras cf. satowi and Colombiceras sp. This is the first systematic palaeontological report of Cretaceous ammonoids from the Philippines. Among the described species, Notosilesitoides philippinensis is proposed as a new genus and species. This fauna shows close similarity to that of the Tomochi Formation, Choshi Group, and the Miyako Group in Japan. These faunas were in a warm current regime that extended from the equator. The age and palaeogeographical significance of the assemblage is discussed.

Three new species of Merizocotyle Cerfontaine, 1894 (Monogenea: Monocotylidae) from the nasal tissues of dasyatid rays collected off Malaysian and Indonesian Borneo. Syst Parasitol. 2012 Jun;82(2):167-76 Authors: Chisholm LA, Whittington ID Abstract Three new species of Merizocotyle Cerfontaine, 1894 (Monogenea: Monocotylidae) are described from the nasal tissues of stingrays collected off Borneo. Merizocotyle macrostrobus n. sp. is described from the dwarf whipray Himantura walga (Müller & Henle) collected in shallow waters off Sematan, Sarawak, Malaysia. This species can be distinguished from the other members of the genus by the morphology of the sclerotised male copulatory organ, which is long with many twists and loops. The vaginae of this species are also long and looped. Merizocotyle papillae n. sp. is described from the roughnose stingray Pastinachus solocirostris Last, Manjaji & Yearsley collected off Sematan and Mukah, Sarawak, Malaysia. It is distinguished from the other species of Merizocotyle by the morphology of the male copulatory organ, which is a sclerotised tube that expands slightly and then tapers at the distal end, and by the presence of papillae on the dorsal edge of the haptor. Merizocotyle rhadinopeos n. sp. is described from the whitenose whip ray Himantura uarnacoides (Bleeker) collected off Manggar, East Kalimantan, Indonesia. It can be differentiated by the male copulatory organ, which is a short, narrow, curved, sclerotised tube tapering distally, and the path of the ovary, which runs anteriorly to the base of the oötype. We also provide details of new host and/or locality records for M. australensis (Beverley-Burton & Williams, 1989) Chisholm, Wheeler & Beverley-Burton, 1995, M. icopae Beverley-Burton & Williams, 1989 and M. pseudodasybatis (Hargis, 1955) Chisholm, Wheeler & Beverley-Burton, 1995.

Rhabdias esculentarum n. sp. (Nematoda: Rhabdiasidae) from green frogs of the Rana esculenta species complex in Italy: molecular evidence, morphological description and genetic differentiation from its congeners in frogs and toads. Syst Parasitol. 2012 Jun;82(2):131-46 Authors: Cipriani P, Mattiucci S, Paoletti M, Santoro M, Nascetti G Abstract A new taxon, Rhabdias esculentarum n. sp., is described based on DNA sequence analysis at multiple loci (i.e. mtDNA cox-1, 12S rRNA, ITS-1 and partial ITS-2 regions of the nuclear rDNA) and morphometric analysis carried out on specimens collected from the green frogs of the Rana esculenta species complex in Italy (i.e. R. lessonae Camerano and R. esculenta Linnaeus, identified genetically by diagnostic allozyme loci). Rhabdias esculentarum n. sp. was differentiated genetically, at both mitochondrial and nuclear levels, from Rh. bufonis (Schrank, 1788) (sensu Hartwich, 1972) and Rh. sphaerocephala Goodey, 1924 recovered from the toad Bufo bufo Linnaeus collected sympatrically with the specimens of Rana lessonae and R. esculenta examined in the present study. Moreover, the new taxon proved to be different from the other species of Rhabdias from anurans, which had previously been sequenced using the same genes and deposited in GeneBank. Phylogenetic analyses (MP and ML) inferred from mitochondrial (mtDNA cox-1 and 12S ribosomal RNA) and nuclear (ITS-1 and ITS-2 of the rDNA regions) sequences datasets were congruent in depicting Rh. esculentarum n. sp. as forming a highly supported clade distinct from the sympatric species Rh. bufonis, as well as from Rh. sphaerocephala, characterised on the basis of the same loci. Morphometric analysis and the differential diagnosis of genetically characterised specimens of the new species have revealed differences in several features in comparison with the type-species, Rh. bufonis. Material of the latter species included voucher specimens from Germany deposited by Hartwich (1972) and other specimens collected from B. bufo in Italy. Among the diagnostic characters, the particular cup-shaped buccal capsule characterising Rh. esculentarum is clearly different from the tear-shaped buccal capsule observed in material of R. bufonis obtained from Berlin Museum and collected in the same geographical area as the green frogs under study. Rh. esculentarum was also found to differ in some measurements and allometric characters from Rh. bufonis (sensu Moravec et al., 1997). The data so far collected appear to indicate a host-preference of Rh. esculentarum for Rana lessonae and R. esculenta, which belong to the R. esculenta hybridogenetic species complex in Italy.

Description of a new species of Eimeria Schneider, 1875 (Apicomplexa: Eimeriidae) from the western Derby eland Taurotragus derbianus derbianus Gray (Artiodactyla: Bovidae) in Senegal. Syst Parasitol. 2012 Jun;82(2):121-3 Authors: Máca O Abstract Examination of faecal samples from semi-captive western Derby elands Taurotragus derbianus derbianus Gray, in the Bandia and Fathala Reserves of Senegal, revealed the presence of oöcysts of the genus Eimeria Schneider, 1875 that we considered to represent a new species, Eimeria derbiani n. sp. The new species possesses nearly ellipsoidal oöcysts (length/width ratio 1.3) with a bi-layered wall and an average size of 27.6 × 21.5 μm. E. derbiani possesses a micropyle covered by a micropylar cap and ovoidal, single-layered sporocysts with an average size of 14.9 × 7.7 μm, each with a Stieda body. Sporozoites of E. derbiani possess a large refractile body and a nucleus. Sporulation lasted for 2 days at 23°C. The new species is differentiated from the two species parasitising Taurotragus oryx Pallas, E. canna Triffitt, 1924 and E. triffittae Yakimoff, 1934. PMID: 22581248 [PubMed - in process]

A new species of Euryhaliotrematoides Plaisance & Kritsky, 2004 (Monogenea: Dactylogyridae) from the gills of the spotted rose snapper Lutjanus guttatus (Steindachner) (Perciformes: Lutjanidae). Syst Parasitol. 2012 Jun;82(2):113-9 Authors: Soler-Jiménez LC, García-Gasca A, Fajer-Ávila EJ Abstract Euryhaliotrematoides mehen n. sp. (Monogenea: Dactylogyridae) is described based on specimens collected from the gills of the spotted rose snapper Lutjanus guttatus (Steindachner) off Mazatlan, Sinaloa, on the northwestern coast of Mexico. The synapomorphy of this genus is the presence of a funnel-shaped base of the male copulatory organ. This new species differs from all other species of the genus by possessing a male copulatory organ with a base with a thickened margin and a membranous accessory piece resembling a scarf and covering about 60% of its distal region. PCR products of the 28S rRNA (831 bp) and 18S rRNA (662 bp) genes were sequenced and submitted to GenBank (accession numbers HQ615997 and JF938069, respectively). BLASTn searches revealed no 100% identical hits with the previously registered monogenean sequences. PMID: 22581247 [PubMed - in process]

A new acanthocephalan family, the Isthmosacanthidae (Acanthocephala: Echinorhynchida), with the description of Isthmosacanthus fitzroyensis n. g., n. sp. from threadfin fishes (Polynemidae) of northern Australia.

2012-05-15T23:46:10+01:00

A new acanthocephalan family, the Isthmosacanthidae (Acanthocephala: Echinorhynchida), with the description of Isthmosacanthus fitzroyensis n. g., n. sp. from threadfin fishes (Polynemidae) of northern Australia. Syst Parasitol. 2012 Jun;82(2):105-11 Authors: Smales LR Abstract Isthmosacanthus fitzroyensis n. g., n. sp. is described from two species of protandrous fish, Eleutheronema tetradactylum (Shaw) and Polydactylus macrochir (Günther), from the waters around the coast of northern Australian. The new species can be distinguished from all others by the following combination of characters: proboscis shape and armature (22 rows of 13-14 hooks), short neck, trunk spined anteriorly and having two swellings (one bulbous) with a narrow isthmus in between, long tubular lemnisci and six tubular cement glands. Although I. fitzroyensis has been confused with a species of Pomphorhynchus Monticelli, 1905 in the literature, it can be distinguished from all pomphorhynchids, including species of Longicollum Yamaguti, 1935 and Pyriproboscis Amin, Abdullah & Mhaisen, 2003, by the suite of characters listed above. The placement of the species of Pyriproboscis in the Pomphorhynchidae Yamaguti, 1939 is problematical, because it has a short neck, two distinct hook types comprising the proboscis armature and only two rather than six cement glands. A new family, the Isthmosacanthidae n. fam., is erected to contain Isthmosacanthus together with Gorgorhynchoides Cable & Linderoth, 1963 and Golvanorhynchus Noronha, Fabio & Pinto, 1978, genera having an elongate to clavate proboscis, anterior trunk spines, elongate lemnisci, and six tubular cement glands. The validity of this determination, based on the importance of cement gland number and phylogenetic analysis, is argued. PMID: 22581246 [PubMed - in process]

Magnetococcus marinus gen. nov., sp. nov., a marine, magnetotactic bacterium that represents a novel lineage (Magnetococcaceae fam. nov.; Magnetococcales ord. nov.) at the base of the Alphaproteobacteria. Int J Syst Evol Microbiol. 2012 May 11; Authors: Bazylinski DA, Williams TJ, Lefèvre CT, Berg RJ, Zhang CL, Bowser SS, Dean AJ, Beveridge TJ Abstract Magnetotactic bacteria are a morphologically, metabolically and phylogenetically disparate array of bacteria united by the ability to biomineralize membrane-encased, single-magnetic-domain mineral crystals (magnetosomes) that cause the cell to orient along the Earth's geomagnetic field lines. The most commonly observed type of magnetotactic bacteria is the ubiquitous magnetotactic cocci, which comprise their own phylogenetic group. Strain MC-1, a member of this group, was isolated from water collected from the oxic-anoxic interface of the Pettaquamscutt Estuary in Rhode Island, USA, and cultivated in axenic culture. Cells of strain MC-1 are roughly spherical with two sheathed bundles of flagella at a single pole (bilophotrichous). Strain MC-1 uses polar magnetotaxis, and has a single chain of magnetite crystals per cell. Cells grow chemolithoautotrophically with thiosulfate or sulfide as the electron donors, and chemoorganoheterotrophically on acetate. During autotrophic growth, strain MC-1 relies on the reductive tricarboxylic acid cycle for CO2 fixation. The G + C content is 54.2 mol %. The name Magnetococcus marinus gen. nov., sp. nov.is proposed for strain MC-1, which is nominated as the type strain (=ATCC BAA-1437T = JCM 17883T). A new order (Magnetococcales ord. nov.) and family (Magnetococcaceae fam. nov.) are proposed for the reception of Magnetococcus and related magnetotactic cocci, which are provisionally included in the Alphaproteobacteria as the most basal known lineage of this class.

Spencermartinsiella ligniputridi sp. nov., a yeast species recovered from rotten wood. Int J Syst Evol Microbiol. 2012 May 11; Authors: Dlauchy D, Lee CF, Peter G Abstract Four strains of an undescribed heterothallic yeast species were isolated from rotten wood samples collected at different locations in Hungary. Analysis of sequences of D1/D2 domain of the large subunit ribosomal RNA gene placed the novel species in the genus Spencermartinsiella. The new species can be distinguished from Spencermartinsiella europaea, the single species of the genus, and from Candida cellulosicola, the only recognized anamorphic species of the Spencermartinsiella clade, on the basis of standard phenotypic characters. The relatedness among the four strains of the novel species as well as among them and two closely related strains representing undescribed yeast species is discussed. The name Spencermartinsiella ligniputridi is proposed to accommodate the above noted 4 strains. The type and isotype strains of Spencermartinsiella ligniputridi are NCAIM Y.01992T (=CBS 12585T=NRRL Y-48818T) and NCAIM Y.01936I (=CBS 12586 I=NRRL Y-48819I), respectively.

Paenibacillus vulneris sp. nov., isolated from a necrotic wound. Int J Syst Evol Microbiol. 2012 May 11; Authors: Glaeser SP, Falsen E, Busse HJ, Kämpfer P Abstract A Gram-positive staining, aerobic, endospore-forming bacterium, isolated from a necrotic wound of a 35-year-old man was studied in detail for its taxonomic position. Based on 16S rRNA gene sequence similarity comparisons, strain CCUG 53270T was grouped into the genus Paenibacillus, most closely related to Paenibacillus rigui (97.2%), Paenibacillus xylanisolvens (96.3%) and Paenibacillus chinjuensis (96.1%). The 16S rRNA gene sequence similarity to other Paenibacillus species was ≤ 96%. The chemotaxonomic characterization supported allocation of the strain to the genus Paenibacillus. The major menaquinones were MK-7 (85%) and MK-6 (15%). The polar lipid profile contained the major compounds diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. The polyamine pattern contained predominantly spermidine. The major fatty acids were iso- and anteiso-branched fatty acids. The results of physiological and biochemical tests allowed phenotypic differentiation of strain CCUG 53270T from closely related species. Thus, CCUG 53270T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus vulneris sp. nov. is proposed, with CCUG 53270T (= JCM 18268T) as the type strain.

Comamonas guangdongensis sp. nov., isolated from subterranean forest sediment and emended description of the genus Comamonas.

2012-05-15T23:46:01+01:00

Comamonas guangdongensis sp. nov., isolated from subterranean forest sediment and emended description of the genus Comamonas. Int J Syst Evol Microbiol. 2012 May 11; Authors: Zhang J, Wang Y, Zhou S, Wu C, He J, Li F Abstract A facultative anaerobic bacterium strain CY01T, isolated from the subterranean forest sediment collected from Guangdong Province, China, was investigated by polyphasic taxonomic approach. The cells were short rod, Gram-negative, non-sporulating and motile. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain CY01T showed highest sequence similarities to Comamonas thiooxydans S23T (98.0 %), Comamonas testosteroni JCM 5832T (97.9 %), Comamonas koreensis KCTC 12005T (97.7 %), and Comamonas odontotermitis LMG 23579T (97.0 %). The major respiratory quinone was ubiquinone-8. The major cellular fatty acids were 16:0, 17:0 cyclo, summed feature 3 (16:1ω6c/16:1ω7c) and summed feature 8 (18:1ω6c/18:1ω7c). Based on the phylogenetic analysis, DNA-DNA hybridization, whole-cell fatty acid composition as well as biochemical characteristics, strain CY01T was clearly distinguished from all recognized Comamonas species and should be classified as a novel species of the genus Comamonas, for which the name Comamonas guangdongensis sp. nov. is proposed. The type strain is CY01T (=CCTCC AB 2011133T =KACC 16241T). PMID: 22581903 [PubMed - as supplied by publisher]

Desulfatitalea tepidiphila gen. nov., sp. nov., a novel sulfate-reducing bacterium isolated from tidal flat sediment. Int J Syst Evol Microbiol. 2012 May 11; Authors: Higashioka Y, Kojima H, Watanabe M, Fukui M Abstract A novel sulfate-reducing bacterium, strain S28bFT, was isolated from tidal flat sediment (Tokyo Bay, Japan). Cells of strain S28bFT were rod-shaped (0.5-0.6 × 1.7-3.8 µm), motile, and Gram-negative. For growth, the optimum pH was pH 6.8-7.3 and the optimum temperature was 34-42 °C. Strain S28bFT used sulfate and thiosulfate as electron acceptors, but not nitrate. The G+C content of the genomic DNA was 56.6 mol%. The fatty acid profile of strain S28bFT was characterized by the presence of anteiso-C15:0 and C16:0 as the major components. Phylogenetic analyses based on genes for 16S rRNA, alpha subunit of dissimilatory sulfite reductase (dsrA), and adenosine-5'-phosphosulfate reductase (aprA) revealed that the isolated strain belonged to class Deltaproteobacteria. Its closest relative is Desulfosarcina cetonica DSM 7267T with 16S rRNA gene sequence similarity of 93.3%. Two other strains, S28OL1 and S28OL2 were also isolated from the same sediment. These strains were closely related to S28bFT with 16S rRNA gene similarities of 99%, and the same physiological characteristics were shared with S28bFT. On the basis of phylogenetic and phenotypic characterization, a novel species in a new genus, Desulfatitalea tepidiphila gen. nov., sp. nov. is proposed to accommodate strains obtained in this study, with the type strain S28bFT (=NBRC 107166T =DSM 23472T).

Pseudomonas kuykendallii sp. nov.: A Novel γ-Proteobacteria Isolated From a Hexazinone Degrading Bioreactor. Curr Microbiol. 2012 May 13; Authors: Hunter WJ, Manter DK Abstract Three strains of Gram-negative bacteria designated strains H2(T), H6, and H7 were isolated from bioreactors that degraded the herbicide hexazinone. Similar morphological characteristics, cellular fatty acid profiles, and 16S rRNA gene sequences show that the isolates are members of the same species. These characteristics also show that the isolates belong to the genus Pseudomonas with P. graminis, P. putida, and P. stutzeri as close relatives. The 16S rRNA gene of the H2(T) strain differed from that of type strains for P. graminis, P. putida, and P. stutzeri by 1.9, 2.5, and 2.7 %, respectively, indicating that the H2(T), H6, and H7 strains are related to P. graminis, P. putida, and P. stutzeri but are different enough to represent a novel species. The G+C content of the three strains averaged 61.2 ± 0.8 mol% which is similar to the values reported for P. graminis (61), P. putida (61.6), and P. stutzeri (62.2-65.5). The major cellular fatty acids present in the H2(T) strain were C(18:1) ω7c/C (18:1) ω6c (34.3 %), C(16:1) ω6c/C(16:1) ω7c (27.4 %), C(16:0) (20.6 %), C(12:0) (7.9 %), C(12:0) 3-OH (4.5 %), and C(10:0) 3-OH (3.1 %). The name Pseudomonas kuykendallii sp. nov. is proposed for these bacteria. PMID: 22580889 [PubMed - as supplied by publisher]

Grosmannia and Leptographium spp. associated with conifer-infesting bark beetles in Finland and Russia, including Leptographium taigense sp. nov. Antonie Van Leeuwenhoek. 2012 May 13; Authors: Linnakoski R, de Beer ZW, Duong TA, Niemelä P, Pappinen A, Wingfield MJ Abstract Species of Grosmannia with Leptographium anamorphs include important forest pathogens and agents of blue stain in timber. They are commonly found in association with forest pests, such as bark beetles. During a survey of ophiostomatoid fungi in eastern parts of Finland and neighboring Russia, species belonging to the genus Grosmannia were isolated from 12 different bark beetle species infesting Picea abies and Pinus sylvestris, the most economically important conifers in the region. Identification of these fungi was based on morphology, DNA sequence comparisons for three gene regions and phylogenetic analyses. A total of ten taxa were identified. These belonged to six different species complexes in Grosmannia. The phylogenetic analyses provided an opportunity to redefine the G. galeiformis-, L. procerum-, L. lundbergii-, G. piceiperda-, G. olivacea- and G. penicillata-complexes, and to consider the species emerging from the survey within the context of these complexes. The species included G. galeiformis, G. olivacea, L. chlamydatum, L. lundbergii, L. truncatum and a novel taxon, described here as L. taigense sp. nov. In addition, species closely related to G. cucullata, G. olivaceapini comb. nov., G. piceiperda and L. procerum were isolated but their identity could not be resolved. The overall results indicate that the diversity of Grosmannia species in the boreal forests remains poorly understood and that further studies are needed to clarify the status of several species or species complexes.

Synchroma pusillum sp. nov. and other New Algal Isolates with Chloroplast Complexes Confirm the Synchromophyceae (Ochrophyta) as a Widely Distributed Group of Amoeboid Algae.

Synchroma pusillum sp. nov. and other New Algal Isolates with Chloroplast Complexes Confirm the Synchromophyceae (Ochrophyta) as a Widely Distributed Group of Amoeboid Algae. Protist. 2012 May 10; Authors: Schmidt M, Horn S, Flieger K, Ehlers K, Wilhelm C, Schnetter R Abstract Seven new isolates of the heterokont algal class Synchromophyceae are described from coastal habitats of the Atlantic Ocean, including the Caribbean and Mediterranean Seas. All of the new isolates contain chloroplast complexes, a key feature of this group of algae. Morphology, pigments and DNA sequences support a monophyletic grouping of the Synchromophyceae to the exclusion of other Ochrophyta (primarily photosynthetic stramenopiles). Within the Synchromophyceae, two phylogenetic clades based on rbcL and 18S rDNA data were discovered, which differ in cell size and also the number of plastid complexes per cell. Two isolates form a clade with the type species Synchroma grande, while all other isolates form a separate clade, including the newly described species S. pusillum. Further species delineation of the isolates is difficult due to the highly similar morphology and life cycle strategy. Phylogenetic relationships with other genera of the Ochrophyta, such as Leukarachnion and Chlamydomyxa, are apparent and shed light on a heterogeneous branch of heterokont evolution.

Description of Alpheus cedrici sp. n., a strikingly coloured snapping shrimp (Crustacea, Decapoda, Alpheidae) from Ascension Island, central Atlantic Ocean. Zookeys. 2012;(183):1-15 Authors: Anker A, Grave SD Abstract Alpheus cedricisp. n. is described based on two specimens collected under rocks while scuba diving off the coast of Ascension Island, central Atlantic Ocean. The new species belongs to the Alpheus macrocheles (Hailstone, 1835) species complex and appears to be most closely related to the eastern-central Atlantic Alpheus macrocheles, the western Atlantic Alpheus amblyonyx Chace, 1972, and the eastern Pacific Alpheus bellimanus Lockington, 1877 and Alpheus rectus Kim & Abele, 1988. However, it differs from all these species by a combination of morphological characters and by a diagnostic and striking colour pattern. PMID: 22573945 [PubMed - in process]

Didelphis aurita (Marsupialia, Didelphidae): a New Host for Sarcocystis lindsayi (Apicomplexa, Sarcocystidae).

2012-05-13T12:33:34+01:00

Didelphis aurita (Marsupialia, Didelphidae): a New Host for Sarcocystis lindsayi (Apicomplexa, Sarcocystidae). J Parasitol. 2012 May 9; Authors: Stabenow CD, Ederli NB, Lopes CW, Oliveira FC Abstract Abstract Nine opossums, Didelphis aurita, were captured in the city of Seropédica, State of Rio de Janeiro, Brazil and examined to identify parasite species of the genus Sarcocystis. Sporocysts were observed in the mucosal scrapings of the small intestine from three opossums. Five budgerigars, Melopsittacus undulatus, were infected with sporocysts from each of these infected opossums, and five budgerigars were used as controls. Of the 15 sporocysts-treated budgerigars, five birds, which received sporocysts from one of the infected opossums, developed tissue parasites. Meronts in the vascular endothelium of the lung venous capillaries and cysts in the skeletal and cardiac muscle cells were observed in histological sections stained with hematoxylin and eosin. The microscopic cysts, which were predominantly in the tongue and leg muscles, ranged from 65.25 to 118.06 μm in length, 13.98 to 29.38 μm in width and 0.9 to 1.9 μm in thickness of the cystic wall. Sections examined by transmission electron microscopy revealed that the cyst wall contained numerous slender and jagged-shaped protrusions, each with a finger-like formation at the end. In this study, the morphology, especially of the cyst wall, and the morphometry of the tissue cysts indicate that the parasite is Sarcocystis lindsayi. Therefore, the opossum, D. aurita, is now considered a definitive host for this species in Brazil. PMID: 22571294 [PubMed - as supplied by publisher]

Insights into the Life Cycle of Yeasts from the CTG Clade Revealed by the Analysis of the Millerozyma (Pichia) farinosa Species Complex.

2012-05-13T12:33:32+01:00

Insights into the Life Cycle of Yeasts from the CTG Clade Revealed by the Analysis of the Millerozyma (Pichia) farinosa Species Complex. PLoS One. 2012;7(5):e35842 Authors: Mallet S, Weiss S, Jacques N, Leh-Louis V, Sacerdot C, Casaregola S Abstract Among ascomycetous yeasts, the CTG clade is so-called because its constituent species translate CTG as serine instead of leucine. Though the biology of certain pathogenic species such as Candida albicans has been much studied, little is known about the life cycles of non-pathogen species of the CTG clade. Taking advantage of the recently obtained sequence of the biotechnological Millerozyma (Pichiasorbitophila) farinosa strain CBS 7064, we used MLST to better define phylogenic relationships between most of the Millerozyma farinosa strains available in public collections. This led to the constitution of four phylogenetic clades diverging from 8% to 15% at the DNA level and possibly constituting a species complex (M. farinosa) and to the proposal of two new species:Millerozyma miso sp. nov. CBS 2004(T) (â€Š=â€ŠCLIB 1230(T)) and Candida pseudofarinosa sp. nov.NCYC 386(T)(â€Š=â€ŠCLIB 1231(T)).Further analysis showed that M. farinosa isolates exist as haploid and inter-clade hybrids. Despite the sequence divergence between the clades, secondary contacts after reproductive isolation were evidenced, as revealed by both introgression and mitochondria transfer between clades. We also showed that the inter-clade hybrids do sporulate to generate mainly viable vegetative diploid spores that are not the result of meiosis, and very rarely aneuploid spores possibly through the loss of heterozygosity during sporulation. Taken together, these results show that in this part of the CTG clade, non-Mendelian genetic exchanges occur at high rates through hybridization between divergent strainsfrom distinct clades and subsequent massive loss of heterozygosity. This combination of mechanisms could constitute an alternative sexuality leading to an unsuspected biodiversity. PMID: 22574125 [PubMed - in process]

Sequence Diversity in the Dickeya fliC Gene: Phylogeny of the Dickeya Genus and TaqMan® PCR for 'D. solani', New Biovar 3 Variant on Potato in Europe.

2012-05-11T11:47:01+01:00

Sequence Diversity in the Dickeya fliC Gene: Phylogeny of the Dickeya Genus and TaqMan® PCR for 'D. solani', New Biovar 3 Variant on Potato in Europe. PLoS One. 2012;7(5):e35738 Authors: Van Vaerenbergh J, Baeyen S, De Vos P, Maes M Abstract Worldwide, Dickeya (formerly Erwinia chrysanthemi) is causing soft rot diseases on a large diversity of crops and ornamental plants. Strains affecting potato are mainly found in D. dadantii, D. dianthicola and D. zeae, which appear to have a marked geographical distribution. Furthermore, a few Dickeya isolates from potato are attributed to D. chrysanthemi and D. dieffenbachiae. In Europe, isolates of Erwinia chrysanthemi biovar 1 and biovar 7 from potato are now classified in D. dianthicola. However, in the past few years, a new Dickeya biovar 3 variant, tentatively named 'Dickeya solani', has emerged as a common major threat, in particular in seed potatoes. Sequences of a fliC gene fragment were used to generate a phylogeny of Dickeya reference strains from culture collections and with this reference backbone, to classify pectinolytic isolates, i.e. Dickeya spp. from potato and ornamental plants. The reference strains of the currently recognized Dickeya species and 'D. solani' were unambiguously delineated in the fliC phylogram. D. dadantii, D. dianthicola and 'D. solani' displayed unbranched clades, while D. chrysanthemi, D. zeae and D. dieffenbachiae branched into subclades and lineages. Moreover, Dickeya isolates from diagnostic samples, in particular biovar 3 isolates from greenhouse ornamentals, formed several new lineages. Most of these isolates were positioned between the clade of 'D. solani' and D. dadantii as transition variants. New lineages also appeared in D. dieffenbachiae and in D. zeae. The strains and isolates of D. dianthicola and 'D. solani' were differentiated by a fliC sequence useful for barcode identification. A fliC TaqMan®real-time PCR was developed for 'D. solani' and the assay was provisionally evaluated in direct analysis of diagnostic potato samples. This molecular tool can support the efforts to control this particular phytopathogen in seed potato certification. PMID: 22570692 [PubMed - in process]

New records of the ectoparasitic flagellate Colpodella gonderi on non-Colpoda ciliates. Int Microbiol. 2011 Dec;14(4):207-11 Authors: Olmo JL, Esteban GF, Finlay BJ Abstract Colpodella gonderi is the only ectoparasitic flagellate of ciliated protozoa described thus far. This investigation reveals new records of C. gonderi retrieved from soil samples in southern Scotland, UK. Of fourteen ciliates species identified in one single occasion, three of them, Colpoda steinii, Pseudoplatyophrya nana and Grossglockneria acuta, were infested with the parasite. These results provide further evidence that C. gonderi is not host-specific of the ciliate genus Colpoda. PMID: 22569758 [PubMed - in process]

Agromyces indicus sp. nov., isolated from mangroves sediment in Chorao Island, Goa, India. Antonie Van Leeuwenhoek. 2012 May 9; Authors: Dastager SG, Qiang ZL, Damare S, Tang SK, Li WJ Abstract A Gram-positive, non-motile, rod-shaped bacterium strain NIO-1018(T) isolated from a mangrove sediment sample of the Chorao Island, Goa, India, was subjected to a detailed polyphasic taxonomic study. The strain designated as NIO-1018(T) matched with most of the phenotypic and chemotaxonomic properties of the genus Agromyces and represents a novel species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NIO-1018(T) fell within the cluster comprising species of the genus Agromyces, clustering with Agromyces soli (98.1 %), Agromyces flavus (97.9 %), Agromyces aurantiacus (97.7 %) and Agromyces ulmi (97.3 %). The predominant menaquinone was MK-12, and the major cellular fatty acids were anteiso-C(15:0), iso-C(16:0), anteiso-C(17:0) and iso-C(15:0). The polar lipids consisted of diphosphatidylglycerol and phosphatidylglycerol. The genomic DNA G+C content of strain NIO-1018(T) was 71.8 mol%. The combination of phylogenetic analysis, DNA-DNA relatedness, phenotypic characteristics and chemotaxonomic data supported the view that strain NIO-1018(T) represents a novel species of the genus Agromyces, for which the name Agromyces indicus sp. nov. is proposed. The type strain is NIO-1018 (=JCM 17573(T) = CCTCC AB2011122(T)). PMID: 22569993 [PubMed - as supplied by publisher]

Systematic palaeontology and taphonomic significance of the mollusc fauna from the Mata Amarilla Formation (lower Upper Cretaceous), southern Patagonia, Argentina

2012-05-11T11:46:59+01:00

Publication year: 2012Source:Cretaceous ResearchMiguel Griffin, Augusto N. Varela Thirteen mollusc taxa are described from the Mata Amarilla Formation, a lower Upper Cretaceous unit exposed in southern Patagonia, Argentina. Of these, one is a new bivalve species, Pterotrigonia flava sp. nov. The fauna was collected from two sections representing different parts of the basin. Sedimentary characteristics at each one, together with the fossil content and taphonomic features of the preserved material, confirm that these localities represent littoral environments (lagoon). The two sections contain autochthonous elements, and beds with mixed autochthonous and parautochthonous fauna. The latter exhibits a marine shoreface influence, possibly owing to washover deposits. The possible age of the fossil-bearing rocks in the sections studied is late Albian–early Cenomanian.

Synchroma pusillum sp. nov. and other New Algal Isolates with Chloroplast Complexes Confirm the Synchromophyceae (Ochrophyta) as a Widely Distributed Group of Amoeboid Algae

2012-05-11T11:46:57+01:00

Publication year: 2012Source:ProtistMaria Schmidt, Susanne Horn, Kerstin Flieger, Katrin Ehlers, Christian Wilhelm, Reinhard Schnetter Seven new isolates of the heterokont algal class Synchromophyceae are described from coastal habitats of the Atlantic Ocean, including the Caribbean and Mediterranean Seas. All of the new isolates contain chloroplast complexes, a key feature of this group of algae. Morphology, pigments and DNA sequences support a monophyletic grouping of the Synchromophyceae to the exclusion of other Ochrophyta (primarily photosynthetic stramenopiles). Within the Synchromophyceae, two phylogenetic clades based on rbcL and 18S rDNA data were discovered, which differ in cell size and also the number of plastid complexes per cell. Two isolates form a clade with the type species Synchroma grande, while all other isolates form a separate clade, including the newly described species S. pusillum. Further species delineation of the isolates is difficult due to the highly similar morphology and life cycle strategy. Phylogenetic relationships with other genera of the Ochrophyta, such as Leukarachnion and Chlamydomyxa, are apparent and shed light on a heterogeneous branch of heterokont evolution.

TWO NEW SPECIES OF THE GENUS SCHIZORCHIS (CESTODA: ANOPLOCEPHALIDAE) FROM LEPORIDS (LAGOMORPHA: LEPORIDAE) IN CHINA.

2012-05-10T00:29:12+01:00

TWO NEW SPECIES OF THE GENUS SCHIZORCHIS (CESTODA: ANOPLOCEPHALIDAE) FROM LEPORIDS (LAGOMORPHA: LEPORIDAE) IN CHINA. J Parasitol. 2012 May 4; Authors: Cai K, Cai K, Bai J, Chen S Abstract Abstract Four specimens of wild leporids, Lepus capensis Linnaeus, 1758 in Longde County, Ningxia Hui Autonomous Region (NXHAR), and 40 domestic rabbits，Oryctolagus cuniculus(Linnaeus, 1758) (20 from Xiji County, NXHAR, and 20 from Jingning County, Gansu Province) were studied for the presence of helminth parasites. Two new cestode species of the genus Schizorchis Hansen, 1948 (Anoplocephalidae) were found: Schizorchis sinensis sp. n. from L. capensis and Schizorchis oryctolagi sp. n. from domestic rabbits. S. sinensis sp. n. is distinguished from all the species of Schizorchis from pikas, Ochotona spp. (Lagomorpha: Ochotonidae) by having much longer strobila, larger cirrus sac, greater number of segments and more numerous testes. The morphology of S. oryctolagi n. sp. is most similar to that of S. sinensis. It is distinguished from S. sinensis by its relatively small strobila, larger number of segments, smaller size of eggs and much larger cirrus sac, which is substantially extending in medial direction. In addition, a genital papilla is present in S. sinensis but absent in S. oryctolagi. These findings indicate that species of Schizorchis are widespread in leporid mammals, contrary to the widespread opinion that the latter genus is specific to the lagomorph mammals of the family Ochotonidae. They are congruent with the hypothesis of the close phylogenetic relationships between the genera Schizorchis and Mosgovoyia. The occurrence of Schizorchis spp. in leporids is considered relict, vestigial from wider geographical and host ranges of this parasite genus in Pleistocene.

Sphingobacterium cladoniae sp. nov., Isolated from Lichen, Cladonia sp., and emended description of Sphingobacterium siyangense. Int J Syst Evol Microbiol. 2012 May 4; Authors: Lee DH, Hur JS, Kahng HY Abstract A strictly aerobic, Gram-staining-negative bacterium, designated strain No.6(T), was isolated from a lichen (Cladonia sp.) collected in Geogeum Island, Korea and its taxonomic status was established by a polyphasic study. Cells of strain No.6(T) were non-motile, catalase- and oxidase-positive, non-spore-forming rods. Growth was observed at 15-35 °C (optimum, 25-30 °C), at pH 5.0-10.0 (optimum, pH 6.0-8.0) and with 0-3% NaCl (optimum, 0-2%). The predominant cellular fatty acids were summed feature 3 (comprising iso-C15:0 2-OH and/or C16:1ω7c, 41.5%), iso-C15:0 (26.7%) and C16:0 (9.6%), and menaquinone MK-7 was the only respiratory quinone. The G+C content of the genomic DNA was 36.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain No.6(T) fell within the evolutionary group encompassed by the genus Sphingobacterium. The levels of 16S rRNA gene sequence similarity between the novel strain and the type strains of recognized Sphingobacterium species ranged from 92.1 to 99.1%, the highest values being with Sphingobacterium siyangense SY1(T) (99.1%) and Sphingobacterium multivorum IAM14316(T) (98.5%). DNA-DNA relatedness between strain No.6(T) and the two type strains were 32.0% and 5.7%, respectively. The polar lipids found in strain No.6(T) were phosphatidylethanolamine, two unidentified phospholipids, three unidentified aminophospholipids, one glycolipid and four unidentified lipids. One unidentified sphingolipid was also found. On the basis of phenotypic and genotypic data, strain No.6(T) represents a novel species of the genus Sphingobacterium, for which the name Sphingobacterium cladoniae sp. nov. is proposed. The type strain is No.6(T) (=KCTC 22613(T) = JCM 16113(T)). An emended description of Sphingobacterium siyangense is also proposed. PMID: 22561594 [PubMed - as supplied by publisher]

Reclassification of Thermoproteus neutrophilus Stetter and Zillig 1989 as Pyrobaculum neutrophilum comb. nov. based on phylogenetic analysis. Int J Syst Evol Microbiol. 2012 May 4; Authors: Chan PP, Cozen AE, Lowe TM Abstract The hyperthermophilic crenarchaeon Thermoproteus neutrophilus V24StaT was originally classified before sequence-based phylogenetic analysis became standard for taxonomy. Subsequent phylogenetic analyses by various groups have shown that strain V24StaT groups more closely with Pyrobaculum strains than with those in the genus Thermoproteus. Based on phylogenetic comparison of ribosomal RNA genes and ribosomal proteins, we propose that strain V24StaT be reclassified as Pyrobaculum neutrophilum comb. nov.

Angustibacter peucedani sp. nov., isolated from rhizosphere soil.

2012-05-10T00:29:11+01:00

Angustibacter peucedani sp. nov., isolated from rhizosphere soil. Int J Syst Evol Microbiol. 2012 May 4; Authors: Lee SD Abstract A strictly aerobic, Gram-positive actinobacterial strain was isolated from a rhizosphere soil of a wild plant (Peucedanum japonicum Thumb.) collected on Mara Island of Jeju, Republic of Korea. Cells of strain RS-50T were oxidase-negative, catalase-positive, short rods and motile by means of a polar flagellum; the colonies were orange-coloured, circular, smooth, convex. meso-Diaminopimelic acid and glucose were the diagnostic diamino acid in the cell wall and the whole-cell sugar, respectively. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, two unknown phospholipid and an unknown lipid. The major fatty acids were iso-C15:0, iso-C16:0, anteiso-C15:0 and anteiso-C17:0. The DNA G+C content was 73.6 mol%. In 16S rRNA gene sequence-based phylogenetic trees, strain RS-50T formed a tight cluster with Angustibacter luteus (99.2% sequence similarity), both of which was loosely related to the suborders Kineosporiineae and Micrococcineae. DNA relatedness of the isolate to A.luteus KACC 14249T was 22.3±0.9%. On the basis of the results of phenotypic analyses and DNA-DNA hybridization experiments, Strain RS-50T (=KCTC 19628T = DSM 45329T) is considered to represent a novel species of the genus Angustibacter, for which the name Angustibacter peucedani sp. nov. is proposed.

Sphingobium limneticum sp. nov., and Sphingobium boeckii, two novel freshwater planktonic members of the family Sphingomonadaceae, and reclassification of Sphingomonas suberifaciens as Sphingobium suberifaciens comb. nov. Int J Syst Evol Microbiol. 2012 May 4; Authors: Chen H, Jogler M, Rohde M, Klenk HP, Busse HJ, Tindall BJ, Spröer C, Overmann J Abstract Two novel chemoorganoheterotrophic members of the Sphingomonadaceae were isolated from alpine and prealpine lakes. Cells stained Gram-negative, were motile and rod-shaped, and formed yellow, circular, convex colonies on different agar media. Strains 301T and 469T were strictly aerobic, catalase- and oxidase-positive, and grew at temperatures between 10 and 40 °C (optimum, 28 °C), and at pH values between 5 and 10 (optimum, pH 7). Both strains contained Q-10 as the dominant quinone, sphingoglycolipids, and 2-hydroxymyristic acid, whereas 3-hydroxy fatty acids were absent. Major fatty acids of strain 301T were C18:1ω7c (53.3%), C16:1ω7c (22.9%), and C14:0 2-OH (10.8%) as the major 2-hydroxy fatty acid. Fatty acids of strain 469T were dominated by C18:1ω7c (34.4%), C16:1ω7c (32.0%), and C14:0 2-OH (15.2%) as the major 2-hydroxy fatty acid. The genomic G+C contents of strains 301T and 469T were 63.4 and 64.6 mol%, respectively. 16S rRNA gene sequence comparison indicated that both strains belonged to the genus Sphingobium. This classification was supported by the presence of spermidine as the major polyamine. The phylogenetically closest relatives of strain 301T are Sphingobium amiense DSM 16289T, S. vermicomposti DSM 21299T, S. yanoikuyae DSM 7462T and S. scionense DSM 19371T (98.8%, 98.0%, 97.9% and 97.4% sequence similarity, respectively). DNA-DNA hybridization of genomic DNA yielded similarities in the range of 43.2 to 12.1% between strain 301T and the type strains of these four Sphingobium species. Closest relatives of strain 469T are Sphingomonas suberifaciens DSM 7465T and Sphingobium scionense DSM 19371T (97.1% and 96.5% sequence similarity of the 16S rRNA gene, respectively). The degree of DNA-DNA hybridisation between strain 469T and Sphingomonas suberifaciens DSM 7465T was 17.9%. Based on the results of the molecular analyses and their phenotypic characteristics, strains 301T and 469T represent two novel species of the genus Sphingobium. The name Sphingobium limneticum is proposed for strain 301T. The type strain is 301T (= DSM 25076T = LMG 26659T). The name Sphingobium boeckii is proposed for strain 469T. The type strain is 469T (= DSM 25079T = LMG 26901T). The polyphasic analysis also suggests that Sphingomonas suberifaciens should be reclassified as Sphingobium suberifaciens comb. nov. with the type strain Ca1T = DSM 7465T.

Sphingobium czechense LL01T sp. nov., isolated from a hexachlorocyclohexane (HCH) dump site. Int J Syst Evol Microbiol. 2012 May 4; Authors: Niharika N, Moskalikova H, Kaur J, Khan F, Sedlackova M, Hampl A, Damborsky J, Prokop Z, Lal R Abstract A yellow pigmented bacterial strain, designated LL01T, was isolated from hexachlorocyclohexane (HCH)-contaminated soil in Spolana Neratovice, former Czech producer of Lindane. A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LL01T occupied a distinct phylogenetic position in the Sphingobium cluster, showing highest similarity with Sphingobium rhizovicinum CC-FH12-1T (98.5%). The DNA G+C content of strain LL01T was 66.1 mol%. The predominant respiratory pigment ubiquonone Q10 is present. The polar lipid profile of the strain LL01T also corresponded to those reported for other Sphingobium species (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine, sphingoglycolipids), supporting its identification as member of the genus Sphingobium. Spermidine was the major polyamine observed in the cell. The results obtained after DNA-DNA hybridization, biochemical and physiological tests clearly distinguished it from closely related species of the genus Sphingobium. Therefore, strain LL01T represents a novel species of the genus Sphingobium for which the name Sphingobium czechense LL01T sp. nov. is proposed (=CCM 7979T=DSM 25410T).

Lacinutrix himadriensis sp. nov., a psychrophilic bacterium isolated from a marine sediment of Kongsfjorden, Svalbard, Arctic and emended description of the genus Lacinutrix. Int J Syst Evol Microbiol. 2012 May 4; Authors: Srinivas TN, Prasad S, Manasa P, Sailaja B, Begum Z, Shivaji S Abstract A novel Gram-negative, rod shaped, non-motile, psychrophilic bacterium, designated strain E4-9aT, was isolated from a marine sediment sample collected at a depth of 276 m from Kongsfjorden, Svalbard, Arctic. The colony color was golden yellow. Strain E4-9aT, was positive for amylase activity at 5oC. The predominant fatty acids were iso-C15:1 G (21.8%), anteiso-C15:0 (19.1%), anteiso-C15:1 A (18.6%), iso-C15:0 (13.8%) and iso-C16:1 H (6.4%). Strain E4-9aT contains MK-6 as the major respiratory quinone. The polar lipids consisted of phosphatidylethanolamine (PE), three unidentified aminolipids (AL1, AL4 and AL5), one unidentified phospholipid (PL) and four unidentified lipids (L1, L4 to L6). Based on the 16S rRNA gene sequence similarity it was ascertained that the closest related species of E4-9aT were Lacinutrix copepodicola, Lacinutrix algicola and Lacinutrix mariniflava with a sequence similarity of 98.5, 96.5 and 95.8% respectively. Phylogenetic analysis showed that strain E4-9aT clustered with Lacinutrix copepodicola and with Lacinutrix algicola and Lacinutrix mariniflava with a distance of 1.5 and 4.8% (98.5 and 95.2% similarity) respectively. However, DNA-DNA hybridization with Lacinutrix copepodicola DJ3T showed a relatedness of 59% with respect to strain E4-9aT. The G + C content of DNA of the strain E4-9aT was 29 mol%. Based on the results of DNA-DNA hybridization and phenotypic data it appears that strain E4-9aT represents a novel species of the genus Lacinutrix, for which the name Lacinutrix himadriensis sp. nov. is proposed. The type strain of Lacinutrix himadriensis sp. nov. is E4-9aT (=CIP 110310T = KCTC 23612T). PMID: 22561589 [PubMed - as supplied by publisher]

Methanothermobacter tenebrarum sp. nov., a hydrogenotrophic thermophilic methanogen isolated from gas-associated formation water of a natural gas field in Japan. Int J Syst Evol Microbiol. 2012 May 4; Authors: Nakamura K, Takahashi A, Mori C, Tamaki H, Mochimaru H, Nakamura K, Takamizawa K, Kamagata Y Abstract A thermophilic and hydrogenotrophic methanogen, strain RMAS(T), was isolated from gas-associated formation water of a gas-producing well in a natural gas field in Japan. Strain RMAS(T) grew solely on H(2)/CO(2) but required either casamino acids, tryptone, yeast extract, or vitamins for growth. Growth of strain RMAS(T) was stimulated by acetate. Cells were non-motile, straight rods, 0.5×3.5-10.5 µm, and occurred singly or in pairs. Bundles of fimbriae occurred at both poles of cells. The cells of strain RMAS(T) possessed a thick cell wall (average 21 nm) as revealed by ultrathin section electron microscopy. Strain RMAS(T) grew at 45-80 °C (optimally at 70 °C), at pH 5.8-8.7 (optimally at pH 6.9-7.7), and at NaCl concentrations of 0.001-20 g l(-1) (optimally at 2.5 g l(-1)). Phylogenetic analyses revealed that Methanothermobacter thermautotrophicus strain ΔH(T) is the most closely related valid strain to RMAS(T) with 95.7 % similarity on the basis of the 16S rRNA gene sequence. On the basis of the morphological, phenotypic, and phylogenetic characteristics of strain RMAS(T), it is clear that strain RMAS(T) represents a novel species of the genus Methanothermobacter, for which we propose Methanothermobacter tenebrarum sp. nov. The type strain is RMAS(T) (DSM 23052(T), JCM 16532(T), NBRC 106236(T)). PMID: 22561588 [PubMed - as supplied by publisher]

Nocardioides panzhihuaensis sp. nov., a novel endophytic actinomycete isolated from medicinal plant Jatropha curcas L. Antonie Van Leeuwenhoek. 2012 May 3; Authors: Qin S, Yuan B, Zhang YJ, Bian GK, Tamura T, Sun BZ, Li WJ, Jiang JH Abstract A novel Gram-positive, aerobic, rod-shaped and mycelia-producing bacterial strain, designated KLBMP 1050(T), was isolated from the stem of the oil-seed plant Jatropha curcas L. collected from Sichuan Province, south-west China. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the isolate KLBMP 1050(T) belonged to the genus Nocardioides, with the highest sequence similarity to Nocardioides albus KCTC 9186(T) (99.38 %) and Nocardioides luteus KCTC 9575(T) (99.03 %). However, the DNA-DNA relatedness of isolate KLBMP 1050(T) to these two type strains were 37.5 ± 3.5 and 33 ± 2.3 %, respectively. Strain KLBMP 1050(T) grew at the pH range 6-11, temperature range 10-32 °C and with 0-12 % NaCl. The physiological properties of strain KLBMP 1050(T) differ from those of N. albus KCTC 9186(T) and N. luteus KCTC 9575(T). The cell-wall peptidoglycan contained LL: -diaminopimelic acid and MK-8(H(4)) was the major respiratory quinone. The predominant cellular fatty acid of strain KLBMP 1050(T) was iso-C(16:0) (23.3 %). The total DNA G+C content was 70.1 mol%. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain KLBMP 1050(T) represents a novel species of the genus Nocardioides, for which the name Nocardioides panzhihuaensis sp. nov. is proposed. The type strain is KLBMP 1050(T) (= KCTC 19888(T) = NBRC 108680(T)). PMID: 22552630 [PubMed - as supplied by publisher]

Luteolibacter cuticulihirudinis sp. nov., isolated from Hirudo medicinalis. Antonie Van Leeuwenhoek. 2012 May 3; Authors: Glaeser SP, Galatis H, Martin K, Kämpfer P Abstract A Gram-negative, coccoid shaped bacterium isolated from the outer surface of the medicinal leech Hirudo medicinalis was characterized. The 16S rRNA gene sequence comparison revealed that the bacterium was closely related to species of the genus Luteolibacter. Luteolibacter pohnpeiensis was the most closely related species (94.6 % sequence similarity), followed by Luteolibacter luojiensis (93.4 %) and Luteolibacter algae (93.3 %). Chemotaxonomic data (major ubiquinone: MK-9; major polar lipids: phosphatidylethanolamine and phosphatidylglycerol; and major fatty acids: iso-C(14:0), C(16:0), iso-C(16:1), and anteiso-C(15:0)) supported the affiliation of the isolate to the genus Luteolibacter. DNA-DNA hybridizations with the type strain of L. pohnpeiensis was 31 % (reciprocal value 30 %). A phenotypic differentiation of strain E100(T) from L. pohnpeiensis and the other Luteolibacter species was possible by several physiological tests. We conclude Strain E100(T) represents a novel species, for which we propose the name Luteolibacter cuticulihirudinis sp. nov. with the type strain E100(T) (=CCM 8400(T) = LMG 26924(T)).

Anatomic location of Mycoplasma mycoides subsp. capri and Mycoplasma agalactiae in naturally infected goat male auricular carriers

2012-05-05T13:00:34+01:00

Publication year: 2012Source:Veterinary Microbiology, Volume 157, Issues 3â€“4Ãngel GÃ³mez-MartÃn, Christian De la Fe, JoaquÃn Amores, Antonio SÃ¡nchez, Antonio Contreras, Ana Paterna, Antonio J. BuendÃa, Juan C. Corrales This study sought to determine whether male goat auricular carriers of mycoplasmas known to cause contagious agalactia could harbour these microorganisms at anatomical sites other than the ears. A microbiological study was conducted in 6 naturally infected bucks that had been diagnosed as chronic auricular asymptomatic carriers of Mycoplasma (M.) mycoides subsp. capri (Mmc) more than one year previously. To detect mycoplasmas, cultures and PCR were performed on 46 samples taken from each goat from the cardio-respiratory, digestive, nervous, lymph and genitourinary systems and several joints. Of a total of 274 samples analyzed, 28 were positive for mycoplasmas (10.1%): Mmc was detected in 17 (6.1%), Mycoplasma (M.) agalactiae in 12 (4.3%) and both microorganisms were identified in one of the samples. In all 6 goats, mixed infection was observed despite none being auricular carriers of M. agalactiae. Mycoplasma spp. were identified at 15 different sites; the most frequent sites being the joints (31.2%, 5 positive samples), lymph nodes (25%, 4 positive samples) and respiratory tract (25%, 4 positive samples). Positive results were also obtained in three brain tissue (18.7%), two cardiac tissue (12.5%) and one ileum, urethra, testicle and bulbourethral gland (6.25%) samples. The histopathological findings may suggest the presence of mild chronic conditions in some of the organs where the bacteria were found. Our findings reveal for the first time the capacity of Mmc and M. agalactiae to colonize several other organ systems in chronically naturally infected auricular carriers, possibly representing an added risk factor for the spread of these microorganisms. In the case of M. agalactiae, colonization seemed to be independent of the animal's auricular carrier state.

Immunoproteomics analysis of whole cell bacterial proteins of Riemerella anatipestifer

2012-05-05T13:00:31+01:00

Publication year: 2012Source:Veterinary Microbiology, Volume 157, Issues 3â€“4Qinghai Hu, Chan Ding, Jing Tu, Xiaolan Wang, Xiangan Han, Yunbing Duan, Shengqing Yu Riemerella antipestifer is one of the most important duck pathogens. It has worldwide distribution, and the lack of the information on bacteriaâ€“host interactions and an effective vaccine are limitations on the control of this infection. In this study, an immunoproteomic assay was used to identify immunogenic proteins among the whole cell bacterial proteins of R. anatipestifer virulent strain Th4. Duck antiserum against R. anatipestifer Th4 recognized 64 protein spots which were transferred from two-dimensional electrophoresis (2-DE) gel of the whole cell bacterial proteins onto polyvinylidene fluoride (PVDF) membrane. Immunogenic proteins on a duplicate gel were excised and identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) and peptide mass fingerprinting (PMF), a total of 34 immunogenic proteins were found. With the exception of OmpA and GroEL, the other 32 proteins were newly recognized immunogenic antigens of R. anatipestifer. In addition, TonB-dependent outer membrane receptor was found to be a cross immunogenic antigen among serotypes 1, 2 and 10 of R. anatipestifer. Bioinformatics analysis showed that most of the immunogenic proteins were located in the outer membrane and cytoplasm, and were involved in cellular processes and metabolism. The newly identified immunogenic proteins of R. anatipestifer may help us to uncover the pathogenesis of the bacteria, develop novel vaccine candidates and serological diagnosis marker.

Publication year: 2012Source:Veterinary Microbiology, Volume 157, Issues 3â€“4Geoffrey Foster, Peter Wragg, Mark S. Koylass, Adrian M. Whatmore, Lesley Hoyles Actinomyces hyovaginalis, an organism initially described from pigs, was recovered from nine sheep and a moufflon. Further strains of A. hyovaginalis were recovered from five samples from pigs over the same period. 16S rRNA sequencing and extensive phenotyping demonstrated high similarity between the ovine and porcine isolates; however differences with respect to erythritol, adonitol and l-arabitol fermentation were detected. Ovine isolates were made from various sample sites including abscesses and highlight the importance of the accurate identification of the various coryneform isolates which affect sheep. A. hyovaginalis can be added to the growing list of coryneforms which can cause disease in sheep including Corynebacterium pseudotuberculosis, Trueperella pyogenes and Arcanobacterium pluranimalium.

More than classical Chlamydia psittaci in urban pigeons

2012-05-05T13:00:26+01:00

Publication year: 2012Source:Veterinary Microbiology, Volume 157, Issues 3â€“4Konrad Sachse, Simone Kuehlewind, Anke Ruettger, Evelyn Schubert, Gernot Rohde In the literature, studies of Chlamydia infection in birds have usually been confined to the search for Chlamydia (C., formerly Chlamydophila) psittaci, so that little is known about the presence of other chlamydial agents. In the present study, cloacal swabs and faeces samples of urban pigeons have been examined by real-time PCR, DNA microarray assays and partial ompA sequencing. Whilst C. psittaci was the predominant chlamydial agent in this pigeon population (75.8% of all Chlamydiaceae positives), the combined use of highly specific and sensitive molecular assays facilitated the detection of atypical serovars of C. psittaci, as well as other species of Chlamydia, such as C. abortus. Detection of C. pecorum and C. trachomatis from an avian host is reported here for the first time. Rather unexpectedly, 19.5% of all Chlamydiaceae-positive cases turned out to be infected with non-classified organisms. The considerable prevalence of these novel agents raises the question of their epidemiological importance and possible role as pathogens. Future surveys in domestic and wild birds will have to take the extended variety of chlamydial organisms into account.

A new Ordovician eurypterid (Arthropoda: Chelicerata) from southeast Turkey: Evidence for a cryptic Ordovician record of Eurypterida

2012-05-04T12:12:42+01:00

Publication year: 2012Source:Gondwana ResearchJames C. Lamsdell, İzzet Hoşgör, Paul A. Selden A new species of eurypterid, Paraeurypterus anatoliensis gen. et sp. nov., is described from the Upper Ordovician (Katian) Şort Tepe Formation of southeast Turkey. The single specimen, preserving the carapace, mesosoma and fragments of appendages, appears morphologically intermediate between the eurypteroid families Dolichopteridae and Eurypteridae. P. anatoliensis retains the plesiomorphic conditions of crescentic eyes with enlarged palpebral lobes and a quadrate carapace with ornamentation consisting of small pustules but also displaying the derived characteristics of genal facets and a row of large acicular scales across the posterior of each tergite. Phylogenetic analysis incorporating each of the major eurypterine clades and all Eurypterina having a three-segmented genital operculum (the triploperculate condition) resolves eurypteroids to be an unnatural group, with Dolichopteridae and Eurypteridae forming part of a grade leading to diploperculate Eurypterina. P. anatoliensis is intermediate between the two eurypteroid families, as is ‘Eurypterus’ minor from the Pentland Hills of Scotland, which is shown to be a distinct genus and assigned to Pentlandopterus gen. nov. Using the phylogenetic topology to infer ghost ranges for each of the major eurypterid clades reveals that the majority of eurypterid superfamilies must have originated by the Katian, indicating a largely unsampled record of Ordovician eurypterids. The occurrence of poor dispersers such as Paraeurypterus in the Ordovician of Gondwana is puzzling, and it has been suggested that they dispersed to the continent during periods of sea level lowstand in the Sandbian and Hirnantian, however this does not explain the lack of Ordovician species in North America and Europe, given the well-sampled nature of these continents, and an alternative is proposed whereby eurypterids originated in Gondwana and radiated out to Laurentia and Baltica in the late Ordovician and early Silurian, thus explaining their sudden appearance in the European and North American rock record.

Disseminated Mycobacterium immunogenum infection presenting with septic shock and skin lesions in a renal transplant recipient.

Disseminated Mycobacterium immunogenum infection presenting with septic shock and skin lesions in a renal transplant recipient. Transpl Infect Dis. 2012 May 1; Authors: Biggs HM, Chudgar SM, Pfeiffer CD, Rice KR, Zaas AK, Wolfe CR Abstract Mycobacterium immunogenum is a relatively new species within the Mycobacterium chelonae-Mycobacterium abscessus group of rapidly growing mycobacteria (RGM). M. immunogenum was first characterized in 2001 and, similar to other RGM, is an ubiquitous environmental organism. This organism has most commonly been implicated in cutaneous infection in both healthy and immunosuppressed patients. To our knowledge, this is the first reported case of septic shock in the setting of disseminated M. immunogenum infection. Definitive identification of this organism requires gene sequencing at specialized centers, which may limit its detection. M. immunogenum is resistant to many anti-mycobacterial agents, and treatment can be especially challenging in transplant patients, given potential drug interactions and added toxicities. It is important to distinguish M. immunogenum from other RGM and determine the susceptibility profile to devise a successful treatment plan, particularly in the transplant population in which it can potentially cause severe, disseminated disease.

Molecular identification and antifungal susceptibility of clinical isolates of Candida rugosa species complex and proposal of the new species Candida neorugosa. J Clin Microbiol. 2012 May 2; Authors: Paredes K, Sutton DA, Cano J, Fothergill AW, Lawhon SD, Zhang S, Watkins JP, Guarro J Abstract Candida rugosa is a poorly known fungal species occasionally involved in human infections. A molecular analysis of the sequences of the D1/D2 domains and the internal transcribed spacer (ITS) region of the ribosomal genes of twenty four clinical isolates phenotypically identified as Candida rugosa demonstrated that only 10 (41.6%) isolates belonged to that species. The other isolates were identified as Candida pararugosa (41.6 %) and Candida pseudorugosa (8.3%). The remaining two isolates, from human and equine infections, respectively, were clearly different from the others and represent a new species proposed here as Candida neorugosa. The closest species by D1/D2 sequences was the Type strain of C. rugosa with only 92.3% similarity. Candida neorugosa can also be differentiated from all other species of the C. rugosa complex by phenotypic features. The eight antifungal drugs tested showed high in vitro activity against the 24 isolates included in this study. PMID: 22553236 [PubMed - as supplied by publisher]

Phylogenetic and Morphological Diversity of Novel Soil Cercomonad Species with a Description of Two New Genera (Nucleocercomonas and Metabolomonas). Protist. 2012 Apr 25; Authors: Brabender M, Kiss AK, Domonell A, Nitsche F, Arndt H Abstract Cercomonads are important components of microbial food webs in soils and aquatic sediments. Here, we investigated the general morphology, behaviour, life cycle and 18S rDNA phylogeny of cercomonad cultures from a German grassland soil habitat. We describe ten new species including two new genera from 23 strains. Three Cercomonas, two Eocercomonas and three Paracercomonas species are described. Based on large phylogenetic distance and distinct morphology, we erect two novel clade B genera near the root of the cercomonad tree. Nucleocercomonas nov. gen. bears a number of characters unusual for cercomonads: Its anterior flagellum is extremely long, it mostly does not glide, and in its most frequent life stage the cell body does not attach to the substratum, but produces unattached pseudopodia. Furthermore, it has a unique nucleus with a peripheral nucleolus that attaches to the nuclear envelope opposite the basal body connection. Metabolomonas nov. gen. is extremely metabolic. It is characterized by a very high beating frequency of the anterior flagellum, fast gliding, rapid changes in shape and strong cytoplasmic streams. A new genus Brevimastigomonas is erected for the previously described species Paracercomonas anaerobica. The general morphology of cercomonad species often does not correspond with their phylogenetic position: closely related species may have a very different morphology.

Endozoicomonas numazuensis sp. nov., a gammaproteobacterium isolated from marine sponges, and emended description of the genus Endozoicomonas Kurahashi and Yokota 2007. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Nishijima M, Adachi K, Katsuta A, Shizuri Y, Yamasato K Abstract Two strains of non-motile, rod-shaped gammaproteobacteria were isolated from marine sponges collected from the coast of Japan, at Numazu. The isolates were oxidase- and catalase-positive facultative anaerobes that fermented carbohydrates. They required sodium ions for growth and were slightly halophilic, growing in the presence of 1.0%-5.0% (w/v) NaCl with an optimum of 2.0% (w/v). Under aerobic conditions, the major isoprenoid quinones were ubiquinone-9 and menaquinone-9, whereas the minor quinones were ubiquinone-8 and menaquinone-8. Their major cellular fatty acids were C18:1ω7c, C16:1ω7c and C16:0, and the hydroxy acids were C10:0 3-OH and C12:0 3-OH. The DNA G+C content was 48.3-48.7 mol%. Phylogenetic analysis of 16S rDNA sequences placed the isolates within the radiation of the genus Endozoicomonas positioned in a broad clade of uncultured clones recovered from various marine invertebrates. The isolates exhibited 96.5%-96.9% sequence similarity to two Endozoicomonas species, E. elysicola and E. montiporae, and formed a monophyletic cluster with them with a bootstrap support of 100%. Phenotypic features of assimilation of carbohydrates, quinone system and some major cellular fatty acids differed from those of Endozoicomonas species, which are aerobic, produce a scarce or no amount of menaquinone under anaerobic conditions and possess different amounts of C14:0 and/or C18:1ω7c acids. Although some phenotypic differences were identified, the isolates should be assigned to the genus Endozoicomonas on the basis of congruity of phylogeny. The isolates should be classified as a novel species, and the name Endozoicomonas numazuensis sp. nov. is proposed for them. The type strain is HC50T (=NBRC 108893T = DSM 25634T). An emended description of the genus Endozoicomonas is presented. PMID: 22544802 [PubMed - as supplied by publisher]

Novosphingobium barchaimii sp. nov., isolated from a hexachlorocyclohexane (HCH) contaminated soil. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Niharika N, Moskalikova H, Kaur J, Sedlackova M, Hampl A, Damborsky J, Prokop Z, Lal R Abstract A yellow pigmented bacterial strain, designated LL02T was isolated from HCH contaminated soil from Spolana, Neratovice former Czech producer of Lindane. A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LL02T occupied a distinct phylogenetic position in the Novophingobium cluster, showing the highest similarity with Novosphingobium resinovorum NCIMB 8767T (98.59%). The DNA-DNA relatedness values of strain LL02T with its phylogenetic neighbours were found to be less than 70% indicating that strain LL02T represents a novel species of the genus Novosphingobium. The DNA G+C content of strain LL02T was 67.72±0 %. The major respiratory quinone present was ubiquinone Q10. The polar lipid profile of the strain LL02T also corresponded to those reported for other Novosphingobium species (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine and sphingoglycolipids), thus supporting its identification as a member of the genus Novosphingobium. Spermidine was the major polyamine observed in the cell. The major fatty acids are summed feature 3 (consisting of 16:1ω6c and/or 16:1ω7c; 40.13 %) and summed feature 8 (consisting of 18:1 ω7c / and/or 18:1 ω6c, 31.09 %) and 14:0 2-OH (23.16%) was the major hydroxyl fatty acid. The results obtained after DNA-DNA hybridization, biochemical and physiological tests clearly distinguished the strain from closely related species of the genus Novosphingobium. Thus, the strain LL02T represents a novel species of the genus Novosphingobium for which the name Novosphingobium barchaimii LL02T sp. nov. is proposed (CCM= 7980T, DSMZ =25411T).

Sphingobium baderi sp. nov., isolated from a hexachlorocyclohexane (HCH) dump site in Spolana. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Kaur J, Moskalikova H, Niharika N, Sedlackova M, Hampl A, Damborsky J, Prokop Z, Lal R Abstract A gram negative, rod-shaped and white coloured bacterial strain designated LL03T, was isolated from hexachlorocyclohexane-contaminated soil in Spolana Neratovice, former Czech producer of Lindane. The strain LL03T was found to be a degrader of α-, γ- and δ- isomers of Hexachlorocyclohexane while no significant degradation activity was observed for β-isomer. A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LL03T occupied a distinct phylogenetic position in the Sphingobium cluster, showing the highest similarity with Sphingobium wenxiniae CC-FH12-1 (99.2%). The DNA G+C content of strain LL03T was 67.0 mol %. The DNA-DNA relatedness values of the strain LL03T with its close phylogenetic neighbours were below the threshold level of 70 %, supporting its identification as a novel species of the genus Sphingobium. The predominant respiratory quinone was ubiquonone Q10. The polar lipid profile of the strain LL03T also corresponded to those reported for other Sphingobium species (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine and sphingoglycolipid) supporting its identification as a member of the genus Sphingobium. Spermidine was identified as the major polyamine. The predominant fatty acids were 16:0 (14.3 %), 16:1 ω7c/16:1 ω6c (21.8 %), 18:1 ω7c/18:1 ω6c (12.1 %) and 14:0 2OH (8.4 %). The polar lipid pattern, presence of spermidine and ubiquinone Q10, the predominance of the cellular fatty acids C18:1ω7c, C16:0 and C14:0 2-OH and the G+C content of the genomic DNA supported the affiliation of the strain to the genus Sphingobium. The results obtained after DNA-DNA hybridization, biochemical and physiological tests clearly distinguished it from closely related species of the genus Sphingobium. Therefore, the strain LL03T represents a novel species of the genus Sphingobium for which the name Sphingobium baderi LL03T sp. nov. is proposed (=CCM 7981(T ) = DSMZ 25433 (T )).

Psychroserpens damuponensis sp. nov., isolated from seawater. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Lee DH, Cho SJ, Kim SM, Lee SB Abstract A novel bacterium, designated F051-1T, isolated from a seawater sample collected from the coast of Damupo beach in Pohang, Korea, was investigated in a polyphasic taxonomic study. Cells were yellow pigmented, strictly aerobic, Gram negative, and rod shaped. The temperature, pH and NaCl ranges for growth were 4-30°C, pH 6.0-9.0 and 1.0-6.0 %, respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain F051-1T belongs to the genus Psychroserpens in the family Flavobacteriaceae. Its closest relatives were Psychroserpens burtonensis ACAM 188T and Psychroserpens mesophilus KOPRI 13649T with 96.8 and 95.7 % 16S rRNA gene sequence similarity, respectively. The major cellular fatty acids were iso-C15:0, iso-C15:1 G, and anteiso-C15:0. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, two unidentified aminolipids, one unidentified phospholipid and eight unidentified lipids. The major respiratory quinone was menaquinone-6 and the genomic DNA G+C content of the strain was 33.5 mol%. On the basis of phenotypic, phylogenetic and genotypic data, strain F051-1T represents a novel species within the genus Psychroserpens, for which the name Psychroserpens damuponensis sp. nov. is proposed. The type strain is F051-1T (= KCTC 23539T = JCM 17632T). PMID: 22544799 [PubMed - as supplied by publisher]

Huanghella arctica gen. nov., sp. nov., a bacterium of the family Cytophagaceae isolated from Arctic tundra soil on the Svalbard Archipelago, Norway (78{degrees}N). Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Jiang F, Xiao M, Chen L, Kan W, Peng F, Dai J, Chang X, Li W, Fang C Abstract A novel strictly aerobic, red-pigmented, Gram-reaction-negative bacterium, designated strain R9-9T, was isolated from a tundra soil near Ny-Ålesund, Svalbard Archipelago, Norway (78°N), and subjected to a polyphasic taxonomic study. It grew optimally at 20-22°C and at pH 7.0. Flexirubin-type pigments were absent. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain R9-9T represents a distinct phyletic line that reflects a novel generic status within the family Cytophagaceae with relatively low sequence similarities (< 88.0 %) to members of other genera with validly published names. Strain R9-9T contained summed feature 3 (C16:1ω7c and/or C16:1 ω6c, 36.4 %), iso-C17:0 -3OH (13.4 %), iso-C15:0 (11.5 %) and C16:1ω5c (9.2 %) as the predominant cellular fatty acids and phosphatidylethanolamine as the main polar lipid. The major respiratory quinone was MK-7 and the DNA G+C content was 56.1 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain R9-9T is considered to represent a novel species in a new genus in the family Cytophagaceae, for which the name Huanghella arctica gen. nov., sp. nov. is proposed. The type strain is R9-9T (=CCTCC AB 2010418T = NRRL B-59750T). PMID: 22544798 [PubMed - as supplied by publisher]

Dehalococcoides mccartyi gen. nov., sp. nov., obligate organohalide-respiring anaerobic bacteria, relevant to halogen cycling and bioremediation, belong to a novel bacterial class, Dehalococcoidetes classis nov., within the phylum Chloroflexi. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Löffler FE, Yan J, Ritalahti KM, Adrian L, Edwards EA, Konstantinidis KT, Müller JA, Fullerton H, Zinder SH, Spormann AM Abstract Six obligate anaerobic bacterial isolates (195, CBDB1, BAV1, VS, FL2 and GT) with strictly organohalide-respiring metabolisms were isolated from chlorinated solvent-contaminated aquifers, contaminated and uncontaminated river sediments or anoxic digester sludge. Cells were non-motile with a disc-shaped morphology of 0.3 to 1 μm in diameter, a thickness of 0.1-0.2 μm, and characteristic indentations on opposite flat sides of the cell. Growth occurred in completely synthetic, reduced medium amended with a haloorganic electron acceptor (i.e., mostly chlorinated but also some brominated compounds), hydrogen as electron donor, acetate as carbon source, and vitamins. No other growth-supporting redox couples were identified. Aqueous hydrogen consumption threshold concentrations were <1 nM. Growth ceased when vitamin B12 was omitted from the medium. Addition of sterile cell-free supernatant of Dehalococcoides-containing enrichment cultures enhanced dechlorination and growth of strains 195 and FL2, suggesting the existence of so far unidentified stimulants. Dechlorination occurred between pH 6.5 and 8.0 and over a temperature range of 15 to 35°C, with an optimum growth temperature between 25 and 30°C. The major PLFA were 14:0 (15.7 mol%), br15:0 (6.2 mol%), 16:0 (22.7 mol%), 10Me16:0 (25.8 mol%), and 18:0 (16.6 mol%). Unusual furan fatty acids including 9-(5-pentyl-2-furyl)-nonanoate (Fu18:2ω6) and 8-(5-hexyl-2-furyl)-octanoate (Fu18:2ω6) were detected in strains FL2, BAV1 and GT, but not in strains 195 and CBDB1. The 16S rRNA gene sequences of the six isolates shared greater than 98% identity, and phylogenetic analysis revealed an affiliation with the Chloroflexi phylum and a greater than 10% sequence divergence from other described isolates. The genome sizes and G+C contents ranged from 1.34 to 1.47 Mbp and 47 to 48.9 mol% G+C, respectively. Based on 16S rRNA gene sequence comparisons, genome-wide average nucleotide identity (ANI) and phenotypic characteristics, the organohalide-respiring isolates represent a new genus, for which the name Dehalococcoides gen. nov. is proposed. Isolates BAV1 (ATCC BAA-2100 = JCM 16839 = KCTC 5957), FL2 (ATCC BAA-2098 = DSM 23585 = JCM 16840 = KCTC 5959), GT (ATCC BAA-2099 = JCM 16841 = KCTC 5958), CBDB1, 195 (ATCC BAA-2266 = KCTC 15142), and VS are considered strains of the novel species Dehalococcoides mccartyi gen. nov., sp. nov. Dehalococcoides mccartyi sp. nov. strain 195T is designated as the type species of the genus. PMID: 22544797 [PubMed - as supplied by publisher]

Bizionia hallyeonensis sp. nov., isolated from seawater of an oyster farm. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Yoon JH, Kang CH, Jung YT, Kang SJ Abstract A Gram-staining-negative, non-spore-forming, aerobic, non-flagellated, non-gliding, rod-shaped bacterial strain, T-y7T, was isolated from seawater of an oyster farm in the South Sea, Korea, and subjected to a polyphasic study. Strain T-y7T grew optimally at 25 °C, at pH 7.0-8.0 and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain T-y7T fell within the clade comprising Bizionia species, forming a coherent cluster with the type strains of B. algoritergicola, B. argentinensis, B. echini and B. myxarmorum, with which it exhibited 16S rRNA gene sequence similarity values of 97.4-98.9 % and mean DNA-DNA relatedness values of 11-27 %. Strain T-y7T contained MK-6 as the predominant menaquinone and iso-C15:1 G, summed feature 3 (C16:1 ω7c and/or iso-C15:0 2-OH), iso-C15:0 and iso-C17:0 3-OH as the major fatty acids. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The DNA G+C content was 37.1 mol%. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain T-y7T is separate from other Bizionia species. On the basis of the data presented, strain T-y7T is considered to represent a novel species of the genus Bizionia, for which the name Bizionia hallyeonensis sp. nov. is proposed. The type strain is T-y7T (= KCTC 23881T = CCUG 62110T). PMID: 22544796 [PubMed - as supplied by publisher]

Bacteroides reticulotermitis sp. nov., isolated from the gut of the subterranean termite (Reticulitermes speratus). Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Sakamoto M, Ohkuma M Abstract An obligately anaerobic, non-pigmented, non-spore-forming, Gram-negative rod-shaped strain isolated from the gut of the subterranean termite Reticulitermes speratus, Rs-03T, was characterized by determining phenotypic and biochemical features, cellular fatty acid profiles, menaquinone profiles and the phylogenetic positions based on 16S rRNA gene sequence analysis. 16S rRNA gene sequence analysis showed that the isolate was a member of the genus Bacteroides. The strain was related to Bacteroides thetaiotaomicron with 95.0 % 16S rRNA gene sequence similarity. The next closely related species to the isolate were Bacteroides faecis (94.8 %) and Bacteroides xylanisolvens (94.3 %). In addition, hsp60 gene sequence analysis suggested that the isolate was different from known Bacteroides species. The strain was saccharolytic and produced succinic and acetic acids, with small amounts of propionic acid, as metabolic end products. The major cellular fatty acids of strain Rs-03T were anteiso-C15:0, C18:1ω9c and iso-C17:0 3-OH. The major menaquinones were MK-10 and MK-9 and the genomic DNA G+C content was 44.9 mol%. Based on these data, we propose a novel Bacteroides species, Bacteroides reticulotermitis sp. nov. The type strain of Bacteroides reticulotermitis is Rs-03T (= JCM 10512T = CCUG 62153T).

Arenibacter hampyeongensis sp. nov., a marine bacterium isolated from a tidal flat in Yellow Sea of Korea. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Jeong SH, Jin HM, Kim JM, Jeon CO Abstract A Gram-staining-negative, dark orange-pigmented, strictly aerobic bacterium, designated strain HP12T, was isolated from a tidal flat of Hampyeong in Korea. Cells were moderately halotolerant, catalase- and oxidase-positive and non-motile rods. Growth was observed at 5-35°C (optimum, 25°C), at pH 6.0-8.5 (optimum, pH 7.0-7.5) and in the presence of 1-6 % (w/v) NaCl (optimum: 1-2 %). The major cellular fatty acids were summed feature 3 (comprising C16:1ω7c and/or iso-C15:0 2-OH), iso-C17:0 3-OH, C15:0, iso-C15:1 G and iso-C15:0. The polar lipid pattern indicated the presence of phosphatidylethanolamine and two unidentified lipids. The G+C content of the genomic DNA was 37.1 mol% and the predominant respiratory quinone was menaquinone 6. Phylogenetic inference based on 16S rRNA gene sequences showed that the strain formed a tight phyletic lineage with members of the genus Arenibacter. Strain HP12T was most closely related to Arenibacter palladensis LMG 21972T, Arenibacter troitsensis KMM 3674T and Arenibacter echinorum KMM 6032T with similarities of 98.1 %, 98.0 % and 97.8 %, respectively. However, the DNA-DNA relatedness values between strain HP12T and A. palladensis JCM 13509T, A. troitsensis KCTC 12362T and A. echinorum KCTC 22013T were 20.2±0.3 %, 22.6±0.6 % and 9.1±2.6 %, respectively. On the basis of phenotypic and molecular features, strain HP12T represents a novel species of the genus Arenibacter, for which the name Arenibacter hampyeongensis sp. nov. is proposed. The type strain is HP12T (=KACC 16193T = JCM 17788T). PMID: 22544794 [PubMed - as supplied by publisher]

Chryseolinea serpens gen. nov., sp. nov., a novel member of the Bacteroidetes.

2012-05-03T04:18:38+01:00

Chryseolinea serpens gen. nov., sp. nov., a novel member of the Bacteroidetes. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Kim JJ, Alkawally M, Brady AL, Rijpstra WI, Sinninghe Damsté JS, Dunfield PF Abstract An aerobic chemoheterotrophic gliding bacterium was isolated from a soil in Germany and designated strain RYG(T). Cells of this strain are Gram-negative thin rods 0.4 to 0.6 µm in width and 2.0 to 5.5 µm in length. Cells multiplied by normal cell division and no resting stages were observed. Colonies were yellow-pigmented, and displayed swarming edges. Gliding motility was observed in wet mounts. Strain RYG(T) grows in a pH range of 5.6 to 7.7 (Optimum 6.6-7.0), at temperatures between 13 and 37°C (Optimum 25-30°C), and NaCl concentrations of 0-1.0 % (Optimum 0-0.1%). It is incapable of atmospheric nitrogen fixation. Strain RYG(T) grows on most mono- and disaccharides, as well as on a few polysaccharides and organic acids. The predominant menaquinone is MK-7 and the major cellular fatty acids are 16:1 ω5c, i15:0 and major intact polar lipids are composed of phosphatidylethanolamine derivatives and two unknown series. The cellular G+C content is 49.9 mol%. Based on 16S rRNA phylogeny, the isolate belongs to the Bacteroidetes phylum, Class Cytophagia, Order Cytophagales, but is only distantly related to any cultured bacterium. The most closely related relatives are Ohtaekwangia koreensis 3B-2(T) at 93% similarity and Ohtaekwangia kribbensis 10AO(T) at 92%. We propose a novel genus and species, Chryseolinea serpens gen. nov., sp. nov., for this bacterium. Strain RYG(T) (=DSM 24574(T) =ATCC BAA-2075(T)) is the type strain.

Hymenobacter ginsengisoli sp. nov., isolated from soil of a ginseng field. Int J Syst Evol Microbiol. 2012 Apr 27; Authors: Hoang VA, Kim YJ, Nguyen NL, Yang DC Abstract A Gram negative, non-motile, red bacterium, designated DCY57T, was isolated from ginseng soil of a ginseng field in a mountainous region of Chungnam province in South Korea and its taxonomic position was investigated by using a polyphasic approach. Strain DCY57T grew within a range of 0-0.5 % (w/v) NaCl, and the optimum temperature for growth was 30 °C. Strain DCY57T contained MK-7 as the predominant menaquinone. The polyamine pattern is sym-homospermidine. The major fatty acids were C16:1ω5c. iso-C15:0, anteiso-C15:0 and summed Feature 3 containing C16:1ω7c/ C16:1ω6c. The major polar lipids of strain DCY57T were phosphatidylethanolamine (PE), an unknown aminophospholipid (APL3), an unknown aminolipid (AL1). The DNA G+C content was 58.9 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence was used to determine the taxonomic position of strain DCY57T, which is most closely related to species of the genus Hymenobacter, with similarity levels of 91.7-95.8 %. On the basis of the evidence presented in this study, strain DCY57T represents a novel species within the genus Hymenobacter, for which the name Hymenobacter ginsengisoli sp. nov., is proposed. The type strain DCY57T (=KCTC 23674T = JCM 17841T) is JN090860. PMID: 22544792 [PubMed - as supplied by publisher]
