Filobacterium rodentium gen. nov., sp. nov., a member of Filobacteriaceae fam. nov. within the phylum Bacteroidetes; includes a microaerobic filamentous bacterium isolated from specimens from diseased rodent respiratory tracts
More LessStrain SMR-CT, which was originally isolated from rats as the SMR strain, had been named ‘cilia-associated respiratory bacillus’ (‘CAR bacillus’). ‘CAR bacillus’ was a Gram-stain-negative, filamentous argentophilic bacterium without flagella. SMR-CT grew at 37 °C under microaerobic conditions, showed gliding activity, hydrolysed urea and induced chronic respiratory diseases in rodents. The dominant cellular fatty acids detected were iso-C15 : 0 and anteiso-C15 : 0. The DNA G+C content was 47.7 mol%. 16S rRNA gene sequence analysis revealed SMR-CT and other strains of ‘CAR bacillus’ isolated from rodents all belonged to the phylum Bacteroidetes. The nearest known type strain, with 86 % 16S rRNA gene sequence similarity, was Chitinophaga pinensis DSM 2588T in the family Chitinophagaceae. Strain SMR-CT and closely related strains of ‘CAR bacillus’ rodent-isolates formed a novel family-level clade in the phylum Bacteroidetes with high bootstrap support (98–100 %). Based on these results, we propose a novel family, Filobacteriaceae fam. nov., in the order Sphingobacteriales as well as a novel genus and species, Filobacterium rodentium gen. nov., sp. nov., for strain SMR-CT. The type strain is SMR-CT ( = JCM 19453T = DSM 100392T).

A novel rod-shaped, Gram-stain-negative, non-gliding and aerobic strain surrounded by a multilayer capsule, designated 4-T-2T, was isolated from a till sample of Collins glacier front, Antarctica. The bacterium formed yellow, circular, convex and smooth colonies. Growth occurred at 4–28 °C (optimum18–20 °C), at pH 7.0–10.0 (optimum pH 9.0) and with 0–1 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 4-T-2T belonged to the genus Flavobacterium. Strain 4-T-2T shared the highest 16S rRNA gene sequence similarity with the type strain of Flavobacterium algicola (96.7 %). The DNA G+C content of strain 4-T-2T was 36.2 mol%. The only menaquinone was MK-6. The major cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G, iso-C16 : 0 and summed feature 9 (comprising iso-C17 : 1ω9c and/or 10-methyl C16 : 0). Polar lipid profile consisted phosphatidylethanolamine, one unidentified aminolipid, one unidentified aminophospholipid and one unidentified lipid. On the basis of phylogenetic, physiological and chemotaxonomic data, strain 4-T-2T is considered to represent a novel species of the genus Flavobacterium, for which the name Flavobacterium collinsense sp. nov. is proposed. The type strain is 4-T-2T ( = CCTCC AB 2014004T = LMG 28257T).

Occallatibacter riparius gen. nov., sp. nov. and Occallatibacter savannae sp. nov., acidobacteria isolated from Namibian soils, and emended description of the family Acidobacteriaceae
More LessThree Gram-negative, non-spore-forming, encapsulated bacteria were isolated from a Namibian river-bank soil (strains 277T and 307) and a semiarid savannah soil (strain A2-1cT). 16S rRNA gene sequence analyses placed them within subdivision 1 of the Acidobacteria and revealed 100 % similarity between strains 277T and 307 and 98.2 % similarity between A2-1cT and the former two strains. The closest relatives with validly published names were Telmatobacter bradus, Acidicapsa borealis and Acidicapsa ligni (94.7–95.9 % similarity to the type strains). Cells of all three strains were rod-shaped and motile and divided by binary fission. Ultrastructural analyses revealed a thick cell envelope, resulting mainly from a thick periplasmic space. Colonies of strains 277T and 307 were white to cream and light pink, respectively, while strain A2-1cT displayed a bright pink colour. All three strains were aerobic, chemoheterotrophic mesophiles with a broad temperature range for growth and a moderately acidic pH optimum. Sugars and complex proteinaceous substrates were the preferred carbon and energy sources. A few polysaccharides were degraded. The major quinone in all three strains was MK-8; MK-7 occurred in strain A2-1cT as a minor compound. Major fatty acids were iso-C15 : 0 and iso-C17 : 1ω7c. In addition, iso-C17 : 0 occurred in significant amounts. The DNA G+C contents of strains 277T, 307 and A2-1cT were 59.6, 59.9 and 58.5 mol%, respectively. Based on these characteristics, the three isolates are assigned to two novel species of the novel genus Occallatibacter gen. nov., Occallatibacter riparius sp. nov. [type strain 277T ( = DSM 25168T = LMG 26948T) and reference strain 307 ( = DSM 25169 = LMG 26947)] and Occallatibacter savannae sp. nov. [type strain A2-1cT ( = DSM 25170T = LMG 26946T)]. Together with several other recently described taxa, the novel isolates provide the basis for an emended description of the established family Acidobacteriaceae.

Group 16SrXI phytoplasma strains, including subgroup 16SrXI-B and a new subgroup, 16SrXI-D, are associated with sugar cane white leaf
Sugar cane white leaf (SCWL) is a serious disease caused by phytoplasmas. In this study, we performed nested PCR with phytoplasma universal primer pairs (P1/P7 and R16F2n/R16R2) for the 16S rRNA gene to detect SCWL phytoplasmas in 31 SCWL samples collected from Baoshan and Lincang, Yunnan, China. We cloned and sequenced the nested PCR products, revealing that the 16S rRNA gene sequences from 31 SCWL samples were all 1247 bp in length and shared more than 99 % nucleotide sequence similarity with the 16S rRNA gene sequences of SCWL phytoplasmas from various countries. Based on the reported 16S rRNA gene sequence data from SCWL isolates of various countries, we conducted phylogenetic and virtual RFLP analysis. In the resulting phylogenetic tree, all SCWL isolates clustered into two branches, with the Lincang and Baoshan SCWL phytoplasma isolates belonging to different branches. The virtual RFLP patterns show that phytoplasmas of the Lincang branch belong to subgroup 16SrXI-B. However, the virtual RFLP patterns revealed by HaeIII digestion of phytoplasmas of the Baoshan branch differed from those of subgroup 16SrXI-B. According to the results of phylogenetic and virtual RFLP analysis, we propose that the phytoplasmas of the Baoshan branch represent a new subgroup, 16SrXI-D. These findings suggest that SCWL is caused by phytoplasmas from group 16SrXI, including subgroup 16SrXI-B and a new subgroup, 16SrXI-D.

The underestimated diversity of phytoplasmas in Latin America
More LessPhytoplasmas (‘Candidatus Phytoplasma’) are insect-transmitted, cell-wall-less, plant-pathogenic bacteria that cause economically important crop diseases. Because phytoplasmas are difficult or impossible to culture in vitro, they are classified taxonomically according to the convention used for unculturable micro-organisms. The first coherent scheme of classification of phytoplasmas, based on the RFLP pattern of the 16S rRNA-encoding gene generated with 17 restriction endonucleases, was updated several times until the development of the iPhyClassifier. iPhyClassifier is an interactive online tool capable of determining the species, group and subgroup of ‘Candidatus Phytoplasma’ of unknown samples using the 16S F2nR2 sequence. Latin America, an important geographical area in relation to food production, has a high incidence of plant diseases caused by phytoplasmas. However, many phytoplasmas associated with these diseases have not been properly classified. An extensive literature review and the use of iPhyClassifier allowed us to identify two new tentative groups (16SrXXXIII-A and 16SrXXXIV-A) and the following tentative new subgroups among Latin American strains that were either previously unclassified or misclassified: six in 16SrI, six in 16SrII, one in 16SrIII, one in 16SrVII, one in 16SrIX, one in 16SrXII and two in 16SrXIII.

Reclassification of Desulfurococcus mobilis as a synonym of Desulfurococcus mucosus, Desulfurococcus fermentans and Desulfurococcus kamchatkensis as synonyms of Desulfurococcus amylolyticus, and emendation of the D. mucosus and D. amylolyticus species descriptions
Representatives of the crenarchaeal genus Desulfurococcus are strictly anaerobic hyperthermophiles with an organotrophic type of metabolism. Since 1982, five Desulfurococcus species names have been validly published: Desulfurococcus mucosus, D. mobilis, D. amylolyticus, D. fermentans and D. kamchatkensis. Recently, the genomic sequences of all five species became available, promoting the refinement of their taxonomic status. Analysis of full-length high-quality 16S rRNA gene sequences shows that the sequences of D. mobilis and D. mucosus are 100 % identical and differ by 2.2 % from those of D. amylolyticus, D. fermentans and D. kamchatkensis. The latter three sequences differ from each other by 0.1–0.3 % (99.9 % similarity in the D amylolyticus–D. kamchatkensis pair and 99.7 % in the pairs involving D. fermentans). In silico prediction of DNA–DNA hybridization (DDH) values by comparison of genomes using ggdc 2.0 blast+ at http://ggdc.dsmz.de/ produced results that correlated with the 16S rRNA gene sequence similarity values. In the D. mucosus–D. mobilis and D. amylolyticus–D. kamchatkensis pairs, the predicted DDH values were 99 and 92 %, respectively, much higher than the recommended 70 % species-delimiting DDH value. Between members of different pairs, these values were no higher than 20 %. For D. fermentans, its predicted DDH values were around 70 % with D. amylolyticus and D. kamchatkensis and no higher than 20 % with D. mobilis and D. mucosus. These results indicated that D. mobilis should be reclassified as a synonym of D. mucosus, whereas D. kamchatkensis and D. fermentans should be reclassified as synonyms of D. amylolyticus.

Lactococcus nasutitermitis sp. nov. isolated from a termite gut
More LessBacterial strain M19T was isolated from the gut of a wood-feeding termite, Nasutitermes hainanensis. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain M19T was related to members of the genus Lactococcus, with sequence similarities ranging from 84.8 to 95.5 %. Comparison of housekeeping gene ropB sequences revealed that strain M19T was well separated from Lactococcus fujiensis JCM 16395T and Lactococcus hircilactis 117T. The isolate was Gram-stain-positive, catalase-negative and non-motile. Cells were coccoid or ovoid-shaped, and occurred singly, in pairs or as short chains. Growth of strain M19T occurred at 10–40 °C and at pH 5.0–7.5. The DNA G+C content of strain M19T was 39.6 mol% and the major fatty acids were C16 : 0, cyclo-C19 : 0ω8c, C18 : 1ω9c, summed feature 7 and summed feature 8. Based on the phylogenetic, chemotaxonomic and phenotypic data presented, strain M19T represents a novel species of the genus Lactococcus, for which the name Lactococcus nasutitermitis sp. nov. is proposed. The type strain is M19T ( = CGMCC 1.15204T = NBRC 111537T).

The status of the species Enterobacter siamensis Khunthongpan et al. 2014 . Request for an Opinion
More LessIn the course of a taxonomic study describing novel species of the genus Enterobacter it was found that the 16S rRNA gene sequence of the type strain of Enterobacter siamensis, obtained both directly from the authors of the publication on Enterobacter siamensis and from the Korean Collection for Type Cultures (C2361T and KCTC 23282T, respectively), was not congruent with the 16S rRNA gene sequence deposited in the GenBank database under the accession number HQ888848, which was applied for phylogenetic analysis in the species proposal. The remaining deposit in the Japanese type culture collection, NBRC 107138T, showed an identical 16S rRNA gene sequence to the other two cultures and overall, this sequence differed at 35 positions in comparison with the 1429 bp sequence published under the accession number HQ888848.Therefore, the type strain of this species cannot be included in any further scientific comparative study. It is proposed that the Judicial Commission of the International Committee on Systematics of Prokaryotes place the name Enterobacter siamensis on the list of rejected names, if a suitable replacement for the type strain is not found or a neotype strain is not proposed within two years following the publication of this Request for an Opinion.
