A rod-shaped, motile anaerobic bacterium, designated CCRI-22567T, was isolated from a vaginal sample of a woman diagnosed with bacterial vaginosis and subjected to a polyphasic taxonomic study. The novel strain was capable of growth at 30-42 °C (optimum, 42 °C), at pH 5.5-8.5 (optimum, pH 7.0-7.5) and in the presence of 0-1.5â% (w/v) NaCl (optimally at 0.5â% NaCl). The phylogenetic trees based on 16S rRNA gene sequences showed that strain CCRI-22567T forms a distinct evolutionary lineage independent of other taxa in the family Peptostreptococcaceae. Strain CCRI-22567T exhibited 90.1â% 16S rRNA gene sequence similarity to Peptoanaerobacter stomatis ACC19aT and 89.7â% to Eubacterium yurii subsp. schtitka ATCC 43716. The three closest organisms with an available whole genome were compared to strain CCRI-22567T for genomic relatedness assessment. The genomic average nucleotide identities (OrthoANIu) obtained with Peptoanaerobacter stomatis ACC19aT, Eubacterium yurii subsp. margaretiae ATCC 43715 and Filifactor alocis ATCC 35896T were 71.8, 70.3 and 69.6â%, respectively. Strain CCRI-22567T contained C18â:â1 ω9c and C18â:â1 ω9c DMA as the major fatty acids. The DNA G+C content of strain CCRI-22567T based on its genome sequence was 33.8âmol%. On the basis of the phylogenetic, chemotaxonomic and other phenotypic properties, strain CCRI-22567T is considered to represent a new genus and species within the family Peptostreptococcaceae, for which the name Criibacterium bergeronii gen. nov., sp. nov., is proposed. The type strain of Criibacterium bergeronii is CCRI-22567T (=LMG 31278T=DSM 107614T=CCUG 72594T).
