Abstract
A novel, Gram-negative marine bacterium, S2753T, was isolated from a mussel of the Solomon Sea, Solomon Islands. Analysis of the 16S rRNA gene sequence and whole genome sequence data placed strain S2753T in the genus Photobacterium with the closest relative being Photobacterium halotolerans DSM 18316T (97.7 % 16S rRNA gene similarity). Strain S2753T was able to grow from 15 to 40 °C and in NaCl concentrations of 0.5 to 9 % (w/v). The predominant fatty acids were 16 : 1ω7c/16 : 1ω6c (27.9 %), 16 : 0 (22.1 %) and 18 : 1ω7c/8 : 1ω6c (21.4 %). The genomic DNA G+C mol content was 49.5 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic differences, strain S2753T is considered to represent a novel species of the genus Photobacterium. Furthermore, whole genome sequence analysis comparing S2753T and type-strains of closely related species of the genus Photobacterium also demonstrated that the strain is genomically distinct enough to be considered a novel species. The name Photobacterium galatheae is proposed and the type-strain is S2753T( = LMG 28894T = DSM 100496T).

Abstract
The precise delineation of lineages and clonal groups are a prerequisite to examine within-species genetic variations, particularly with respect to pathogenic potential. A whole-genome-based approach was used to subtype and subgroup isolates of Listeria monocytogenes. Core-genome typing was performed, employing 3 different approaches: total core genes (CG), high-scoring segment pairs (HSPs), and average nucleotide identity (ANI). Examination of 113 L. monocytogenes genomes available in-house and in public domains revealed 33 phylogenomic groups (PGs). Each PG could be differentiated into a number of genomic types (GTs), depending on the approach used: HSPs (n = 57 GTs), CG (n = 71 GTs), and ANI (n = 83 GTs). Demarcation of the PGs was concordant with the 4 known lineages and led to the identification of sublineages in the lineage groups I, II, and III. In addition, PG assignments had discriminatory power similar to multi-virulence-locus sequence typing types and clonal complexes of multilocus sequence typing. Clustering of genomically highly similar isolates from different countries, sources, and isolation dates using whole-genome-based PG suggested that dispersion of phylogenomic clones of L. monocytogenes preceded their subsequent evolution. Classification according to PG may act as a guideline for future epidemiological studies.

Abstract
Escherichia coli is a major etiological agent of intra-mammary infections (IMI) in cows, leading to acute mastitis and causing great economic losses in dairy production worldwide. Particular strains cause persistent IMI, leading to recurrent mastitis. Virulence factors of mammary pathogenic E. coli (MPEC) involved pathogenesis of mastitis as well as those differentiating strains causing acute or persistent mastitis are largely unknown. This study aimed to identify virulence markers in MPEC through whole genome and phenome comparative analysis. MPEC strains causing acute (VL2874 and P4) or persistent (VL2732) mastitis were compared to an environmental strain (K71) and to the genomes of strains representing different E. coli pathotypes. Intra-mammary challenge in mice confirmed experimentally that the strains studied here have different pathogenic potential, and that the environmental strain K71 is non-pathogenic in the mammary gland. Analysis of whole genome sequences and predicted proteomes revealed high similarity among MPEC, whereas MPEC significantly differed from the non-mammary pathogenic strain K71, and from E. coli genomes from other pathotypes. Functional features identified in MPEC genomes and lacking in the non-mammary pathogenic strain were associated with synthesis of lipopolysaccharide and other membrane antigens, ferric-dicitrate iron acquisition and sugars metabolism. Features associated with cytotoxicity or intra-cellular survival were found specifically in the genomes of strains from severe and acute (VL2874) or persistent (VL2732) mastitis, respectively. MPEC genomes were relatively similar to strain K-12, which was subsequently shown here to be possibly pathogenic in the mammary gland. Phenome analysis showed that the persistent MPEC was the most versatile in terms of nutrients metabolized and acute MPEC the least. Among phenotypes unique to MPEC compared to the non-mammary pathogenic strain were uric acid and D-serine metabolism. This study reveals virulence factors and phenotypic characteristics of MPEC that may play a role in pathogenesis of E. coli mastitis.

Abstract
Advances in genomic microbial taxonomy have opened the way to create a more universal and transparent concept of species but is still in a transitional stage towards becoming a defining robust criteria for describing new microbial species with minimum features obtained using both genome and classical polyphasic taxonomies. Here we performed advanced microbial taxonomies combined with both genome-based and classical approaches for new agarolytic vibrio isolates to describe not only a novel Vibrio species but also a member of a new Vibrio clade. Two novel vibrio strains (Vibrio astriarenae sp. nov. C7T and C20) showing agarolytic, halophilic and fermentative metabolic activity were isolated from a seawater sample collected in a coral reef in Okinawa. Intraspecific similarities of the isolates were identical in both sequences on the 16S rRNA and pyrH genes, but the closest relatives on the molecular phylogenetic trees on the basis of 16S rRNA and pyrH gene sequences were V. hangzhouensis JCM 15146T (97.8% similarity) and V. agarivorans CECT 5085T (97.3% similarity), respectively. Further multilocus sequence analysis (MLSA) on the basis of 8 protein coding genes (ftsZ, gapA, gyrB, mreB, pyrH, recA, rpoA, and topA) obtained by the genome sequences clearly showed the V. astriarenae strain C7T and C20 formed a distinct new clade protruded next to V. agarivorans CECT 5085T. The singleton V. agarivorans has never been included in previous MLSA of Vibrionaceae due to the lack of some gene sequences. Now the gene sequences are completed and analysis of 100 taxa in total provided a clear picture describing the association of V. agarivorans into pre-existing concatenated network tree and concluded its relationship to our vibrio strains. Experimental DNA-DNA hybridization (DDH) data showed that the strains C7T and C20 were conspecific but were separated from all of the other Vibrio species related on the basis of both 16S rRNA and pyrH gene phylogenies (e.g., V. agarivorans CECT 5085T, V. hangzhouensis JCM 15146T V. maritimus LMG 25439T, and V. variabilis LMG 25438T). In silico DDH data also supported the genomic relationship. The strains C7T also had less than 95% average amino acid identity (AAI) and average nucleotide identity (ANI) towards V. maritimus C210, V. variabilis C206, and V. mediterranei AK1T, V. brasiliensis LMG 20546T, V. orientalis ATCC 33934T, and V. sinaloensis DSM 21326. The name Vibrio astriarenae sp. nov. is proposed with C7 as the type strains. Both V. agarivorans CECT 5058T and V. astriarenae C7T are members of the newest clade of Vibrionaceae named Agarivorans.

Abstract
A novel strain, 22II-S11-z3T, was isolated from the deep-sea sediment of the Atlantic Ocean. The bacterium was aerobic, Gram-staining-negative, oxidase-positive and catalase-negative, oval- to rod-shaped, and non-motile. Growth was observed at salinities of 1-9 % NaCl and temperatures of 10-45 °C. The isolate could hydrolyse aesculin and Tweens 20, 40 and 80, but not gelatin. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 22II-S11-z3T belonged to the genus Aestuariivita, with highest sequence similarity to Aestuariivita boseongensis KCTC 42052T (97.5 %). The average nucleotide identity and digital DNA-DNA hybridization values between strain 22II-S11-z3T and A. boseongensis KCTC 42052T were 71.5 % and 20.0 ± 2.3 %, respectively. The G+C content of the chromosomal DNA was 65.5 mol%. The principal fatty acids (>5 %) were summed feature 8 (C18 : 1ω7c/ω6c) (35.2 %), C19 : 0 cyclo ω8c (20.9 %), C16 : 0 (11.8 %), 11-methyl C18 : 1ω7c (11.4 %) and C12 : 1 3-OH (9.4 %). The respiratory quinone was determined to be Q-10. Diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, nine unidentified phospholipids, one unidentified aminolipid and two unidentified lipids were present. The combined genotypic and phenotypic data show that strain 22II-S11-z3T represents a novel species of the genus Aestuariivita, for which the name Aestuariivita atlantica sp. nov. is proposed, with the type strain 22II-S11-z3T ( = KCTC 42276T = MCCC 1A09432T).

Abstract
The genera Erwinia and Pantoea contain species that are devastating plant pathogens, non-pathogen epiphytes, and opportunistic human pathogens. However, some controversies persist in the taxonomic classification of these two closely related genera. The phylogenomic analysis of these two genera was investigated via a comprehensive analysis of 25 Erwinia genomes and 23 Pantoea genomes. Single-copy orthologs could be extracted from the Erwinia/Pantoea core-genome to reconstruct the Erwinia/Pantoea phylogeny. This tree has strong bootstrap support for almost all branches. We also estimated the in silico DNA-DNA hybridization (isDDH) and the average nucleotide identity (ANI) values between each genome; strains from the same species showed ANI values ≥96% and isDDH values >70%. These data confirm that whole genome sequence data provides a powerful tool to resolve the complex taxonomic questions of Erwinia/Pantoea, e.g. Pantoea agglomerans 299R was not clustered into a single group with other P. agglomerans strains, and the ANI values and isDDH values between them were <91% and around 43.8%, respectively. These data indicate P. agglomerans 299R should not be classified into the P. agglomerans species. In addition, another strain (Pantoea sp. At_9b) was identified that may represent a novel Pantoea species. We also evaluated the performance of six commonly used housekeeping genes (atpD, carA, gyrB, infB, recA, and rpoB) in phylogenetic inference. A single gene was not enough to obtain a reliable species tree, and it was necessary to use the multilocus sequence analysis of the six marker genes to recover the Erwinia/Pantoea phylogeny.

Abstract
Capnocytophaga canimorsus are gram-negative bacteria living as commensals in the mouth of dogs and cats. C. canimorsus cause rare but life-threatening generalized infections in humans that have been in contact with a dog or a cat. Over the last years we collected 105 C. canimorsus strains from different geographical origins and from severe human infections or healthy dogs. All these strains were analyzed by 16S rDNA sequencing and a phylogenetic tree revealed two main groups of bacteria instead of one with no relation to the geographical origin. This branching was confirmed by the whole-genome sequencing of 10 strains, supporting the evidence of a new Capnocytophaga species in dogs. Interestingly, 19 out of 19 C. canimorsus strains isolated from human infections belonged to the same species. Furthermore, most strains from this species could grow in heat-inactivated human serum (HIHS) (40/46 tested), deglycosylate IgM (48/66) and were cytochrome-oxidase positive (60/66) while most strains from the other species could not grow in HIHS (22/23 tested), could not deglycosylate IgM (33/34) and were cytochrome-oxidase negative (33/34). Here, we propose to call Capnocytophaga canis (Latin: dog) the novel, presumably less virulent dog-hosted Capnocytophaga species and to keep the name C. canimorsus for the species including human pathogens.

Abstract
Three Gram-stain-positive, irregular-rod-shaped, non-motile, non-spore-forming bacteria were isolated from nematodes collected from Santa Antao, Cabo Verde (CBX151T, CBX152T) and Kakegawa, Japan (CBX130T). Based on 16S rRNA gene sequence similarity, strains CBX130T, CBX151T and CBX152T were shown to belong to the genus Leucobacter. This affiliation was supported by chemotaxonomic data (2,4-diaminobutyric acid in the cell wall; major respiratory quinones MK-10 and MK-11; major polar lipids phosphatidylglycerol and diphosphatidylglycerol; major fatty acids anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0). Strains CBX130T and CBX152T were found to share salient characteristics. Based on morphological, physiological, chemotaxonomic and biochemical analysis, strain CBX152T represents a novel species of the genus Leucobacter, for which the name Leucobacter musarum sp. nov. (type strain CBX152T = DSM 27160T = CIP 110721T) is proposed. Two subspecies of Leucobacter musarum sp. nov. are proposed: Leucobacter musarum sp. nov. subsp. musarum subsp. nov. (type strain CBX152T = DSM 27160T = CIP 110721T) and Leucobacter musarum sp. nov. subsp. japonicus subsp. nov. (type strain CBX130T = DSM 27158T = CIP 110719T). The third novel strain, CBX151T, showed genetic similarities with Leucobacter celer NAL101T indicating that these strains belong to the same species. Based on morphological, physiological, chemotaxonomic and biochemical differences it is proposed to split the species Leucobacter celer into two novel subspecies, Leucobacter celer subsp. celer subsp. nov. (type strain NAL101T = KACC 14220T = JCM 16465T) and Leucobacter celer subsp. astrifaciens subsp. nov. (type strain CBX151T = DSM 27159T = CIP 110720T), and to emend the description of Leucobacter celerShin et al. 2011.

Abstract
The aim of this study was to reclarify the taxonomic status of strain Bacillus invictae Bi.FFUP1
T by performing comparative analyses with the other four type strains within the Bacillus pumilus group. The digital DNA–DNA hybridization (dDDH) and average nucleotide identity (ANI) values between strains B. invictae Bi.FFUP1
T ( = DSMZ 26896T = MCCC 1A07089T), B. altitudinis 41KF2bT ( = DSMZ 21631T = MCCC 1A06452T), B. safensis FO-36bT ( = DSMZ 19292T = MCCC 1A6451T), B. pumilus ATCC 7061T ( = DSMZ 27T = MCCC 1A06453T) and B. xiamenensis HYC-10T ( = MCCC 1A00008T) were, respectively, 82.90 % and 98.10 %, which are greater than the thresholds for bacterial species delineation, suggesting that they should belong to the same species, while the dDDH and ANI values between strain B. invictae DSMZ 26896T and the other three type strains within the B. pumilus group were below the respective thresholds of 70 % and 95 %. Meanwhile, B. invictae DSMZ 26896T and B. altitudinis 41KF2bT shared 98.7 % gyrB gene sequence similarity based on resequencing, whereas strain B. invictae DSMZ 26896T shared low similarities ( < 95 %) with the other three type strains. In addition, in comparison with those from the other three type strains, phenotypic data of B. invictae DSMZ 26896T and B. altitudinis 41KF2bT, including API 20NE, API ZYM, Biolog GN2 and API 50CHB tests, showed slight differences. The data from these combined genotypic and phenotypic analyses suggest that Bacillus invictae Branquinho et al. 2014 should be regarded as a later heterotypic synonym of Bacillus altitudinis

Abstract
Strain JCE(T) was isolated from the fecal sample of a 24-year-old obese man living in Jeddah, Saudi Arabia. It is an aerobic, Gram-positive, rod-shaped bacterium. This strain exhibits a 16S rRNA nucleotide sequence similarity of 97.5 % with Bacillus niacini, the phylogenetically closest species with standing nomenclature. Moreover, the strain JCE(T) presents many phenotypic differences, when it is compared to other Bacillus species, and shows a low MALDI-TOF Mass Spectrometry score that does not allow any identification. Thus, it is likely that this strain represents a new species. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 4,762,944 bp long genome (1 chromosome but no plasmid) contains 4,654 protein-coding and 98 RNAs genes, including 92 tRNA genes. The strain JCE(T) differs from most of the other closely Bacillus species by more than 1 % in G + C content. In addition, digital DNA-DNA hybridization values for the genome of the strain JCE(T) against the closest Bacillus genomes range between 19.5 to 28.1, that confirming again its new species status. On the basis of these polyphasic data made of phenotypic and genomic analyses, we propose the creation of Bacillus jeddahensis sp. nov. that contains the strain JCE(T).

Abstract
Flavobacterium rivuli Ali et al. 2009 emend. Dong et al. 2013 is one of about 100 species in the genus Flavobacterium (family Flavobacteriacae, phylum Bacteroidetes) with a validly published name, and has been isolated from the spring of a hard water rivulet in Northern Germany. Including all type strains of the genus Myroides and Flavobacterium into the 16S rRNA gene sequence phylogeny revealed a clustering of members of the genus Myroides as a monophyletic group within the genus Flavobacterium. Furthermore, F. rivuli WB 3.3-2T and its next relatives seem more closely related to the genus Myroides than to the type species of the genus Flavobacterium, F. aquatile. The 4,489,248 bp long genome with its 3,391 protein-coding and 65 RNA genes is part of the GenomicEncyclopedia ofBacteria andArchaea project. The genome of F. rivuli has almost as many genes encoding carbohydrate active enzymes (151 CAZymes) as genes encoding peptidases (177). Peptidases comprised mostly metallo (M) and serine (S) peptidases. Among CAZymes, 30 glycoside hydrolase families, 10 glycosyl transferase families, 7 carbohydrate binding module families and 7 carbohydrate esterase families were identified. Furthermore, we found four polysaccharide utilization loci (PUL) and one large CAZy rich gene cluster that might enable strain WB 3.3-2T to decompose plant and algae derived polysaccharides. Based on these results we propose F. rivuli as an interesting candidate for further physiological studies and the role of Bacteroidetes in the decomposition of complex polymers in the environment.

Abstract
Vibrio harveyi CAIM 1792 is a marine bacterial strain that causes mortality in farmed shrimp in north-west Mexico, and the identification of virulence genes in this strain is important for understanding its pathogenicity. The aim of this work was to compare the V. harveyi CAIM 1792 genome with related genome sequences to determine their phylogenic relationship and explore unique regions in silico that differentiate this strain from other V. harveyi strains. Twenty-one newly sequenced genomes were compared in silico against the CAIM 1792 genome at nucleotidic and predicted proteome levels. The proteome of CAIM 1792 had higher similarity to those of other V. harveyi strains (78%) than to those of the other closely related species Vibrio owensii (67%), Vibrio rotiferianus (63%) and Vibrio campbellii (59%). Pan-genome ORFans trees showed the best fit with the accepted phylogeny based on DNA-DNA hybridization and multi-locus sequence analysis of 11 concatenated housekeeping genes. SNP analysis clustered 34/38 genomes within their accepted species. The pangenomic and SNP trees showed that V. harveyi is the most conserved of the four species studied and V. campbellii may be divided into at least three subspecies, supported by intergenomic distance analysis. blastp atlases were created to identify unique regions among the genomes most related to V. harveyi CAIM 1792; these regions included genes encoding glycosyltransferases, specific type restriction modification systems and a transcriptional regulator, LysR, reported to be involved in virulence, metabolism, quorum sensing and motility.

Abstract
Strain FF4T was isolated from the skin flora of a 16-year-old healthy Senegalese female. This strain exhibited a 16S rRNA sequence similarity of 97.5 % with Bacillus fumarioli, the phylogenetically closest species with standing in nomenclature and a poor MALDI-TOF-MS score (1.1 to 1.3) that does not allow any identification. Using a polyphasic study consisting of phenotypic and genomic analyses, strain FF4T was Gram-positive, aerobic, rod-shaped, and exhibited a genome of 4,563,381 bp (1 chromosome but no plasmid) with a G + C content of 40.8 % that coded 4,308 protein-coding and 157 RNA genes (including 5 rRNA operons). On the basis of these data, we propose the creation of Bacillus dielmoensis sp. nov.

Abstract
Here we report a summary classification and the features of five anaerobic oral bacteria from the family Peptostreptococcaceae. Bacterial strains were isolated from human subgingival plaque. Strains ACC19a, CM2, CM5, and OBRC8 represent the first known cultivable members of “yet uncultured” human oral taxon 081; strain AS15 belongs to “cultivable” human oral taxon 377. Based on 16S rRNA gene sequence comparisons, strains ACC19a, CM2, CM5, and OBRC8 are distantly related to Eubacteriumyurii subs. yurii and Filifactor alocis, with 93.2 – 94.4 % and 85.5 % of sequence identity, respectively. The genomes of strains ACC19a, CM2, CM5, OBRC8 and AS15 are 2,541,543; 2,312,592; 2,594,242; 2,553,276; and 2,654,638 bp long. The genomes are comprised of 2277, 1973, 2325, 2277, and 2308 protein-coding genes and 54, 57, 54, 36, and 28 RNA genes, respectively. Based on the distinct characteristics presented here, we suggest that strains ACC19a, CM2, CM5, and OBRC8 represent a novel genus and species within the family Peptostreptococcaceae, for which we propose the name Peptoanaerobacter stomatis gen. nov., sp. nov. The type strain is strain ACC19aT (=HM-483T; =DSM 28705T; =ATCC BAA-2665T).

Abstract
Wolbachia are highly extended bacterial endosymbionts that infect arthropods and filarial nematodes and produce contrasting phenotypes on their hosts. Wolbachia taxonomy has been understudied. Currently, Wolbachia strains are classified into phylogenetic supergroups. Here we applied phylogenomic analyses to study Wolbachia evolutionary relationships and examined metrics derived from their genome sequences such as average nucleotide identity (ANI), in silico DNA-DNA hybridization (DDH), G+C content, and synteny to shed light on the taxonomy of these bacteria. Draft genome sequences of strains wDacA and wDacB obtained from the carmine cochineal insect Dactylopius coccus were included. Although all analyses indicated that each Wolbachia supergroup represents a distinct evolutionary lineage, we found that some of the analyzed supergroups showed enough internal heterogeneity to be considered as assemblages of more than one species. Thus, supergroups would represent supraspecific groupings. Consequently, Wolbachia pipientis nomen species would apply only to strains of supergroup B and we propose the designation of 'Candidatus Wolbachia bourtzisii', 'Candidatus Wolbachia onchocercicola', 'Candidatus Wolbachia blaxterii', 'Candidatus Wolbachia brugii', 'Candidatus Wolbachia taylorii', 'Candidatus Wolbachia collembolicola' and 'Candidatus Wolbachia multihospitis' for other supergroups.

Abstract
A Gram-reaction-negative, facultatively anaerobic and rod-shaped bacterium, designated strain JN14CK-3T, was isolated from surface sediment of the Jiulong River of China and was characterized phenotypically and phylogenetically. Phylogenetic analysis of the 16S rRNA gene sequences indicated that strain JN14CK-3T belonged to the genus Draconibacterium, with the highest sequence similarity (98.3 %) to Draconibacterium orientale FH5T. By contrast, strain JN14CK-3T shared low 16S rRNA gene sequence similarities ( < 91.0 %) with other type strains. The sole respiratory quinone was MK-7.The polar lipids were phosphatidylethanolamine and several unidentified phospholipids and lipids. The major fatty acids were iso-C15:0, iso-C16:0, anteiso-C15:0, C17:0 2-OH, iso-C16:0 3-OH and iso-C17:0 3-OH. The G+C content of the genomic DNA was 40.9 mol%. The digital DNA–DNA hybridization value and average nucleotide identity (ANI) between strain JN14CK-3T and D. orientale FH5T were 34.2 ± 2.5 % and 87.1 %, respectively. The combined genotypic and phenotypic data showed that strain JN14CK-3T represents a novel species of the genus Draconibacterium, for which the name Draconibacterium
sediminis sp. nov. is proposed, with the type strain JN14CK-3T ( = MCCC 1A00734T = KCTC 42152T).

Pyrobaculum yellowstonensis Strain WP30 Respires on Elemental Sulfur and/or Arsenate in Circumneutral Sulfidic Geothermal Sediments of Yellowstone National Park. Appl Environ Microbiol 2015; 81:5907-16.

Abstract
Thermoproteales (phylum Crenarchaeota) populations are abundant in high-temperature (>70°C) environments of Yellowstone National Park (YNP) and are important in mediating the biogeochemical cycles of sulfur, arsenic, and carbon. The objectives of this study were to determine the specific physiological attributes of the isolate Pyrobaculum yellowstonensis strain WP30, which was obtained from an elemental sulfur sediment (Joseph's Coat Hot Spring [JCHS], 80°C, pH 6.1, 135 μM As) and relate this organism to geochemical processes occurring in situ. Strain WP30 is a chemoorganoheterotroph and requires elemental sulfur and/or arsenate as an electron acceptor. Growth in the presence of elemental sulfur and arsenate resulted in the formation of thioarsenates and polysulfides. The complete genome of this organism was sequenced (1.99 Mb, 58% G+C content), revealing numerous metabolic pathways for the degradation of carbohydrates, amino acids, and lipids. Multiple dimethyl sulfoxide-molybdopterin (DMSO-MPT) oxidoreductase genes, which are implicated in the reduction of sulfur and arsenic, were identified. Pathways for the de novo synthesis of nearly all required cofactors and metabolites were identified. The comparative genomics of P. yellowstonensis and the assembled metagenome sequence from JCHS showed that this organism is highly related (∼95% average nucleotide sequence identity) to in situ populations. The physiological attributes and metabolic capabilities of P. yellowstonensis provide an important foundation for developing an understanding of the distribution and function of these populations in YNP.

Abstract
Actinobacillus equuli subsp. equuli is a member of the family Pasteurellaceae that is a common resident of the oral cavity and alimentary tract of healthy horses. At the same time, it can also cause a fatal septicemia in foals, commonly known as sleepy foal disease or joint ill disease. In addition, A. equuli subsp. equuli has recently been reported to act as a primary pathogen in breeding sows and piglets. To better understand how A. equuli subsp. equuli can cause disease, the genome of the type strain of A. equuli subsp. equuli, ATCC 19392(T), was sequenced using the PacBio RSII sequencing system. Its genome is comprised of 2,431,533 bp and is predicted to encode 2,264 proteins and 82 RNAs.

Abstract
Families and genera assigned to Tremellomycetes have been mainly circumscribed by morphology and for the yeasts also by biochemical and physiological characteristics. This phenotype-based classification is largely in conflict with molecular phylogenetic analyses. Here a phylogenetic classification framework for the Tremellomycetes is proposed based on the results of phylogenetic analyses from a seven-genes dataset covering the majority of tremellomycetous yeasts and closely related filamentous taxa. Circumscriptions of the taxonomic units at the order, family and genus levels recognised were quantitatively assessed using the phylogenetic rank boundary optimisation (PRBO) and modified general mixed Yule coalescent (GMYC) tests. In addition, a comprehensive phylogenetic analysis on an expanded LSU rRNA (D1/D2 domains) gene sequence dataset covering as many as available teleomorphic and filamentous taxa within Tremellomycetes was performed to investigate the relationships between yeasts and filamentous taxa and to examine the stability of undersampled clades. Based on the results inferred from molecular data and morphological and physiochemical features, we propose an updated classification for the Tremellomycetes. We accept five orders, 17 families and 54 genera, including seven new families and 18 new genera. In addition, seven families and 17 genera are emended and one new species name and 185 new combinations are proposed. We propose to use the term pro tempore or pro tem. in abbreviation to indicate the species names that are temporarily maintained.

Abstract
Eight independent isolates of a Gram-reaction-negative, non-motile rod, were recovered from clinical specimens of New York State patients between the years 2005 and 2013. Four of these isolates were characterized in a taxonomic study using a polyphasic approach that involved phenotypic, phylogenetic and genotypic methodologies. Based on 16S rRNA gene sequence similarity and phylogenetic analysis, the closest relative type strain of the isolates is Paracoccus sphaerophysae HAMBI 3106T (97.7 % 16S rRNA gene sequence similarity). Among the four isolates, the 16S rRNA gene sequence similarity is 100 %. In silico genomic comparisons, including average nucleotide identity (ANI) and the genome-to-genome distance calculator (GGDC), were used as an alternative to DNA–DNA hybridization in this study to support designation of the four isolates as a novel species of the genus Paracoccus. Mass spectrometry profiles were also obtained for the novel isolates using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The predominant cellular fatty acids of the novel isolates were C18 : 1ω7c and C18 : 0. Biochemical analysis and morphological characteristics further contribute to designation of the four isolates as a novel species of the genus Paracoccus, for which the name Paracoccus sanguinis sp. nov. is proposed. The type strain is 05503T( = DSM 29303T = LMG 28451T).

Abstract
Two strains of Gram-negative, facultatively anaerobic, slightly halophilic bacteria, isolated from healthy gilthead sea bream (Sparus aurata) cultured in Spanish Mediterranean fish farms, were different from their closest relatives, Vibrio scophthalmi and V. ichthyoenteri, by phenotypic, phylogenetic and genomic standards. The strains were negative for decarboxylase tests and lacked extracellular hydrolytic activities, but were able to ferment d-mannitol, sucrose, cellobiose and d-gluconate, among other carbohydrates. The major cellular fatty acids were C16:
1 and C16:
0, in agreement with other species of the genus Vibrio. Their 16S rRNA gene sequences were 98.4 and 97.2 % similar to those of the type strains of V. scophthalmi and V. ichthyoenteri, and the similarities using other housekeeping genes (ftsZ, rpoD, recA, mreB and gyrB) and indices of genomic resemblance (average nucleotide identity and estimated DNA–DNA hybridization) between the isolates and those type strains were clearly below intraspecific levels, supporting the recognition of the strains as members of a separate novel species. Thus, we propose the name Vibrio renipiscarius sp. nov., with DCR 1-4-2T ( = CECT 8603T = KCTC 42287T) as the type strain.

Abstract
The Genomic Encyclopedia of Bacteria and Archaea (GEBA) project was launched by the JGI in 2007 as a pilot project to sequence about 250 bacterial and archaeal genomes of elevated phylogenetic diversity. Herein, we propose to extend this approach to type strains of prokaryotes associated with soil or plants and their close relatives as well as type strains from newly described species. Understanding the microbiology of soil and plants is critical to many DOE mission areas, such as biofuel production from biomass, biogeochemistry, and carbon cycling. We are also targeting type strains of novel species while they are being described. Since 2006, about 630 new species have been described per year, many of which are closely aligned to DOE areas of interest in soil, agriculture, degradation of pollutants, biofuel production, biogeochemical transformation, and biodiversity.

The ecology of pelagic freshwater methylotrophs assessed by a high-resolution monitoring and isolation campaign. ISME JOURNAL 2015; 9:2442-53.

Abstract
Methylotrophic planktonic bacteria fulfill a particular role in the carbon cycle of lakes via the turnover of single-carbon compounds. We studied two planktonic freshwater lineages (LD28 and PRD01a001B) affiliated with Methylophilaceae (Betaproteobacteria) in Lake Zurich, Switzerland, by a combination of molecular and cultivation-based approaches. Their spatio-temporal distribution was monitored at high resolution (n=992 samples) for 4 consecutive years. LD28 methylotrophs constituted up to 11 × 10(7) cells l(-1) with pronounced peaks in spring and autumn-winter, concomitant with blooms of primary producers. They were rare in the warm water layers during summer but abundant in the cold hypolimnion, hinting at psychrophilic growth. Members of the PRD01a001B lineage were generally less abundant but also had maxima in spring. More than 120 axenic strains from these so far uncultivated lineages were isolated from the pelagic zone by dilution to extinction. Phylogenetic analysis separated isolates into two distinct genotypes. Isolates grew slowly (μmax=0.4 d(-1)), were of conspicuously small size, and were indeed psychrophilic, with higher growth yield at low temperatures. Growth was enhanced upon addition of methanol and methylamine to sterile lake water. Genomic analyses of two strains confirmed a methylotrophic lifestyle with a reduced set of genes involved in C1 metabolism. The very small and streamlined genomes (1.36 and 1.75 Mb) shared several pathways with the marine OM43 lineage. As the closest described taxa (Methylotenera sp.) are only distantly related to either set of isolates, we propose a new genus with two species, that is, 'Candidatus Methylopumilus planktonicus' (LD28) and 'Candidatus Methylopumilus turicensis' (PRD01a001B).

Abstract
A red-pigmented, bacteriochlorophyll (BChl) a-producing strain, AP64T, was isolated previously from the freshwater Swan Lake located in the western Gobi Desert. Based on its 16S rRNA gene sequence identity (96.1%) to the type strain Gemmatimonas aurantiaca T-27T, the new isolate was tentatively classified as a member of the bacterial phylum Gemmatimonadetes. Here, we report its formal description and polyphasic characterization. Strain AP64T grew best on agar media under 9.8-15.2% atmospheric oxygen. The cells were rods, dividing by symmetrical or asymmetrical binary fission. Budding structures were also observed. Its genomic DNA G+C content was 64.4% (from the draft genome sequence). Phylogenetic analysis based on the 16S rRNA gene sequence clearly separated AP64T from related species. Its genotypic differentiation from phylogenetically close relatives was further supported by performing in silico DNA-DNA hybridization and calculating average nucleotide identity, whereas the high percentage (67.3%) of shared conserved proteins between strain AP64T and Gemmatimonas aurantiaca T-27T supports the classification of the two strains into the same genus. Strain AP64T contained C16 : 1, C14 : 1 and C18 : 1ω9c as predominant fatty acids. The main respiratory quinone was menaquinone 8 (MK-8). The most distinctive feature of strain AP64T was the presence of fully functional purple bacterial photosynthetic reaction centres. The main CO2-fixation pathways were absent. Strain AP64T was capable of growth and BChl production in constant darkness. Thus, strain AP64T is a facultatively photoheterotrophic organism. It represents a novel species of the genus Gemmatimonas, for which the name Gemmatimonasphototrophica sp. nov. is proposed. The type strain is AP64T ( = DSM 29774T = MCCC 1K00454T). Emended descriptions of the genus Gemmatimonas and Gemmatimonas aurantiaca are also provided.

Abstract
A Gram-stain positive, rod shaped aerobic bacterial strain designated Ka25(T) was isolated from a forest soil sample near Kasol, Himachal Pradesh, India. Based on 16S rRNA gene sequence analysis it was identified that strain Ka25(T) belongs to the class Actinobacteria and is most closely related to Nocardioides daejeonensis KCTC 19772(T) (97.2 %), Nocardioides dubius JCM 13008(T) (96.9 %), Nocardioides psychrotolerans CGMCC 1.11156(T) (96.8 %), Nocardioides pacificus DSM 27278(T)(96.7 %) and Nocardioides daphniae JCM 16608(T)(96.4 %) sequence similarity respectively. The chemotaxonomic properties of strain Ka25(T) are consistent with those of the members of the genus Nocardioides: MK-8(H4) is the predominant menaquinone, iso-C16 : 0, iso-C17 : 0 and C18 : 1ω9c were identified as the predominant cellular fatty acids and the cell-wall peptidoglycan is based on LL-2,6-diaminopimelic acid. The DNA G+C content of strain Ka25(T) was determined to be 71.6 mol %. The results of the polyphasic taxonomic analysis allowed a clear differentiation of strain Ka25(T) from all other members of the genus Nocardioides. Strain Ka25(T) is thus considered to represent a novel member of the genus Nocardioides, for which the name Nocardioides solisilvae sp. nov. is proposed. The type strain is Ka25(T) (=KCTC39528(T) =MCC2762(T)).

Abstract
A mesophilic, hydrogenotrophic methanogen, strain S3Fa(T), was isolated from sediments collected by Ocean Researcher I cruise ORI-934 in 2010 near the submarine mud volcano MV4 located at the upper slope of south-west Taiwan. The methanogenic substrates utilized by strain S3Fa(T) were formate and H2/CO2 but not acetate, secondary alcohols, methylamines, methanol or ethanol. Cells of strain S3Fa(T) were non-motile, irregular cocci, 0.5-1.0 μm in diameter. The surface-layer protein showed an Mr of 128,000.The optimum growth conditions were 37 °C, pH 7.1 and 0.17 M NaCl. The DNA G+C content of the genome of strain S3Fa(T) was 62.3 mol%. Phylogenetic analysis revealed that strain S3Fa(T) was most closely related to Methanoculleus marisnigri JR1(T) (99.3% 16S rRNA gene sequence similarity). Genome relatedness between strain S3Fa(T) and Methanoculleus marisnigri JR1(T) was computed using both genome-to-genome distance analysis (GGDA) and average nucleotide identity (ANI) with values of 46.3-55.5% and 93.08%, respectively. Based on morphological, phenotypic, phylogenetic and genomic relatedness data, it is evident that strain S3Fa(T) represents a novel species of the genus Methanoculleus, for which the name Methanoculleus sediminis sp. nov. is proposed. The type strain is S3Fa(T) ( = BCRC AR10044(T) = DSM 29354(T)).

Abstract
The rhizosphere-isolated bacteria belonging to the Bacillus amyloliquefaciens subsp. plantarum and Bacillus methylotrophicus clades are an important group of strains that are used as plant growth promoters and antagonists of plant pathogens. These properties have made these strains the focus of commercial interest. Here, we present the draft genome sequence of B. methylotrophicus KACC 13105(T) ( = CBMB205(T)). Comparative genomic analysis showed only minor differences between this strain and the genome of the B. amyloliquefaciens subsp. plantarum type strain, with the genomes sharing approximately 95% of the same genes. The results of morphological, physiological, chemotaxonomic and phylogenetic analyses indicate that the type strains of these two taxa are highly similar. In fact, our results show that the type strain of B. amyloliquefaciens subsp. plantarum FZB42(T) ( = DSM 23117(T) = BGSC 10A6(T)) does not cluster with other members of the B. amyloliquefaciens taxon. Instead, it clusters well within a clade of strains that are assigned to B. methylotrophicus, including the type strain of that species. Therefore, we propose that the subspecies B. amyloliquefaciens subsp. plantarum should be reclassified as a later heterotypic synonym of B. methylotrophicus.

Abstract
The prevalence of Clostridium difficile infections has increased due to the emergence of epidemic variants from diverse genetic lineages. Here we describe the emergence of a novel variant during an outbreak in a Costa Rican hospital that was associated with severe clinical presentations. This C. difficile variant elicited higher white blood cell counts and caused disease in younger patients than did other strains isolated during the outbreak. Furthermore, it had a recurrence rate, a 30-day attributable disease rate, and disease severity as great as those of the epidemic strain NAP1. Pulsed-field gel electrophoresis genotyping indicated that the outbreak strains belong to a previously undescribed variant, designated NAPCR1. Whole-genome sequencing and ribotyping indicated that the NAPCR1 variant belongs to C. difficile ribotype 012 and sequence type 54, as does the reference strain 630. NAPCR1 strains are resistant to fluoroquinolones due to a mutation in gyrA, and they possess an 18-bp deletion in tcdC that is characteristic of the epidemic, evolutionarily distinct, C. difficile NAP1 variant. NAPCR1 genomes contain 10% more predicted genes than strain 630, most of which are of hypothetical function and are present on phages and other mobile genetic elements. The increased virulence of NAPCR1 was confirmed by mortality rates in the hamster model and strong inflammatory responses induced by bacteria-free supernatants in the murine ligated loop model. However, NAPCR1 strains do not synthesize toxin A and toxin B at levels comparable to those in NAP1 strains. Our results suggest that the pathogenic potential of this emerging C. difficile variant is due to the acquisition of hypothetical functions associated with laterally acquired DNA.

Abstract
A Multilocus Sequence Analysis (MLSA) was performed on members of the Scophthalmi clade in the genus Vibrio, including type and reference strains of the species V. scophthalmi, V. ichthyoenteri, and 39 strains phenotypically identified as Vibrio ichthyoenteri-like, with the aim of better defining boundaries between these two closely related, fish-associated species. The type strain of V. ponticus, recently added to the clade Scophthalmi, was also included. The study was based on partial sequences of the protein-coding housekeeping genes rpoD, mreB, recA, ftsZ, and gyrB, and the 16S rRNA. While the 16S rRNA gene-based trees were unable to pull apart members of V. scophthalmi or V. ichthyoenteri, both the other individual gene trees and the trees obtained from the five-genes concatenated sequences were able to consistently differentiate four subclades within the main clade, corresponding to the bona fide V. scophthalmi, V. ichthyoenteri, and two small ones that may represent a new species each. The best genes to differentiate V. scophthalmi from V. ichthyoenteri were rpoD, recA, and mreB. Vibrio ponticus failed to associate to the clade in the MLSA and in most single gene trees for which it should not be considered part of it. In this study we also confirm using genomic indexes that V. ichthyoenteri and V. scophthalmi are two separate species.

Abstract
Three isolates originating from Spanish-style green-olive fermentations in a manufacturing company in the province of Seville, Spain, were taxonomically characterized by a polyphasic approach. This included a phylogenetic analysis based on 16S rRNA gene sequences and multi-locus sequence analysis (MLSA) based on pyrH, recA, rpoA, gyrB and mreB genes. The isolates shared 98.0 % 16S rRNA gene sequence similarity with Vibrio xiamenensis G21T. Phylogenetic analysis based on 16S rRNA gene sequences using the neighbour-joining and maximum-likelihood methods showed that the isolates fell within the genus Vibrio and formed an independent branch close to V. xiamenensis G21T. The maximum-parsimony method grouped the isolates to V. xiamenensis G21T but forming two clearly separated branches. Phylogenetic trees based on individual pyrH, recA, rpoA, gyrB and mreB gene sequences revealed that strain IGJ1.11T formed a clade alone or with V. xiamenensis G21T. Sequence similarities of the pyrH, recA, rpoA, gyrB and mreB genes between strain IGJ1.11T and V. xiamenensis G21T were 86.7, 85.7, 97.3, 87.6 and 84.8 %, respectively. MLSA of concatenated sequences showed that strain IGJ1.11T and V. xiamenensis G21T are two clearly separated species that form a clade, which we named Clade Xiamenensis, that presented 89.7 % concatenated gene sequence similarity, i.e. less than 92 %. The major cellular fatty acids (>5 %) of strain IGJ1.11T were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). Enzymic activity profiles, sugar fermentation patterns and DNA G+C content (52.9 mol%) differentiated the novel strains from the closest related members of the genus Vibrio. The name Vibrio olivae sp. nov. is proposed for the novel species. The type strain is IGJ1.11T ( = CECT 8064T = DSM 25438T).

Abstract
The genus Pseudomonas currently contains 144 species, making it the genus of Gram-negative bacteria that contains the largest number of species. Currently, multilocus sequence analysis (MLSA) is the preferred method for establishing the phylogeny between species and genera. Four partial gene sequences of housekeeping genes (16S rRNA, gyrB, rpoB, and rpoD) were obtained from 112 complete or draft genomes of strains related to the genus Pseudomonas that were available in databases. These genes were analyzed together with the corresponding sequences of 133 Pseudomonas type strains of validly published species to assess their correct phylogenetic assignations. We confirmed that 30% of the sequenced genomes of non-type strains were not correctly assigned at the species level in the accepted taxonomy of the genus and that 20% of the strains were not identified at the species level. Most of these strains had been isolated and classified several years ago, and their taxonomic status has not been updated by modern techniques. MLSA was also compared with indices based on the analysis of whole-genome sequences that have been proposed for species delineation, such as tetranucleotide usage patterns (TETRA), average nucleotide identity (ANIm, based on MUMmer and ANIb, based on BLAST) and genome-to-genome distance (GGDC). TETRA was useful for discriminating Pseudomonas from other genera, whereas ANIb and GGDC clearly separated strains of different species. ANIb showed the strongest correlation with MLSA. The correct species classification is a prerequisite for most diversity and evolutionary studies. This work highlights the necessity for complete genomic sequences of type strains to build a phylogenomic taxonomy and that all new genome sequences submitted to databases should be correctly assigned to species to avoid taxonomic inconsistencies.

Abstract
A Gram-positive, aerobic, nonmotile actinomycete strain designated DRQ-2(T) was isolated from the soil sample collected from lime-stone open pit mine from the Gulbarga region, Karnataka province, India. Strain DRQ-2(T) was identified as a member of the genus Nonomuraea by a polyphasic approach. Strain DRQ-2(T) could be differentiated from other members of the genus Nonomuraea on the basis of physiology and 16S rRNA gene sequence analysis. The 16S rRNA gene sequence similarity of strain DRQ-2(T) showed highest sequence similarity to Nonomuraea muscovyensis DSM 45913(T) (99.1%), N. salmonea DSM 43678(T) (98.2%) and N. maheshkhaliensis JCM 13929(T) with 98.0%, respectively. Chemotaxonomic properties showing predominant menaquinones of MK-9 (H4), MK-9(H2) and MK-9(H6), major polar lipids comprised diphosphatidylglycerol, phosphatidylmono methyl ethanolamine (PME), phosphatidylethanolamine (PE), hydroxy-PME (OH-PME), hydroxy PE (OH-PEE), phosphatidylglycerol (PG), ninhydrin-positive phosphoglycolipid and unknown phospholipid, fatty acids with major amounts of i-C16:0, ai-C15:0 and ai-C17:0 supported allocation of the strain to the genus Nonomuraea. Results of DNA-DNA hybridization and physiological tests allowed genotypic and phenotypic differentiation of strain DRQ-2(T) from closely related species. The genomic DNA G+C content of the organism was 72.5 mol%. On the basis of phenotypic, chemotypic and molecular characteristics, strain DRQ-2(T) represents a novel species of the genus Nonomuraea, for which the name N. indica sp. nov. is proposed, with type strain DRQ-2(T) (=NCIM 5480(T)= CCTCC AA 209050(T)).

Abstract
A polyphasic taxonomic study was performed on a strain, designated FHC16(T), which was isolated from surface seawater collected from the South China Sea. Cells of strain FHC16(T) are Gram stain-negative, oxidase- and catalase-positive and non-motile rods. Growth was observed at 15-37 °C (optimum, 25-30 °C), at pH 6.0-9.0 (optimum, pH 7.0) and in the presence of 0-5 % (w/v) NaCl (optimum, 3%). 16S rRNA gene sequence analysis showed that strain FHC16(T) is most closely related to Tamlana sedimentorum JCM 19808(T) (98.2% sequence similarity). The ANI value between strain FHC16(T) and T. sedimentorum JCM 19808(T) was found to be 81.82-81.81%. The DNA-DNA hybridization estimated value between strain FHC16(T) and T. sedimentorum JCM 19808(T) was determined to be 25.8 ± 2.41%. The principal fatty acids (>5% of the total) were found to be iso-C(15:0), iso G-C(15:1), iso-C(17:0) 3-OH, iso-C(15:0) 3-OH and summed feature 3 (comprising C(16:1)ω7c/C(16:1)ω6c). The strain was found to have MK-6 as the major respiratory menaquinone, which is consistent with the other three recognized Tamlana species, T. sedimentorum, Tamlana crocina and Tamlana agarivorans. The polar lipids were found to comprise phosphatidylethanolamine, one unidentified aminophospholipid, two unidentified aminolipids and seven unidentified lipids. The G+C content of the chromosomal DNA was determined to be 34.2 mol%. On the basis of phenotypic, chemotaxonomic and molecular data, strain FHC16(T) is considered to represent a novel species of the genus Tamlana, for which the name Tamlana nanhaiensis sp. nov. is proposed. The type strain is FHC16(T) (.LMG 27420(T) = CGMCC 1.12469(T) = MCCC 1A06648(T)).

Abstract
A novel hyperthermophilic, anaerobic, archaeon was isolated from a terrestrial hot spring at Uzon Caldera, Kronotsky Nature Reserve, Kamchatka, Russia. The isolate, strain 1860T, grew optimally at 90–95 °C and pH 6.0–7.0. The cells were non-motile straight rods, 1.5–5.0 µm in length, covered with surface-layer lattice. Strain 1860T utilized complex proteinaceous compounds as electron donors and ferrihydrite, Fe(III) citrate, nitrate, thiosulfate, selenite, selenate and arsenate as electron acceptors for growth. The sequence of the 16S rRNA gene of strain 1860T had 97.9–98.7 % similarity with those of members of the genus
Pyrobaculum
. On the basis of its physiological properties and phylogenetic analyses including in silico genome to genome hybridization, the isolate is considered to represent a novel species, for which the name Pyrobaculum ferrireducens sp. nov. is proposed. The type strain is 1860T ( = DSM 28942T = VKM B-2856T).
