The 16S rRNA gene sequence analysis showed that these strains belonged to the family<jats:italic>Porphyromonadaceae<\/jats:italic>. These strains shared 100\u200a% 16S rRNA gene sequence similarity with each other and were related to<jats:italic>Parabacteroides distasonis<\/jats:italic>(showing 86\u200a% sequence similarity). The strains were found to be obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative rods. Growth of the strains was inhibited on medium containing 20\u200a% bile. The major menaquinones of the isolates were MK-11 and MK-12. This menaquinone composition was different from those of other genera of the family<jats:italic>Porphyromonadaceae<\/jats:italic>, such as<jats:italic>Parabacteroides<\/jats:italic>(in which the predominant menaquinones are MK-9 and MK-10),<jats:italic>Porphyromonas<\/jats:italic>(MK-9 and MK-10) and<jats:italic>Tannerella<\/jats:italic>(MK-10 and MK-11). This is an important chemotaxonomic characteristic of these micro-organisms. The DNA G+C content of strain C46<jats:sup>T<\/jats:sup>is 52.0\u2005mol%. On the basis of these data, strains C46<jats:sup>T<\/jats:sup>and C47 represent a novel genus and species, for which the name<jats:italic>Barnesiella viscericola<\/jats:italic>gen. nov., sp. nov. is proposed. The type strain of<jats:italic>Barnesiella viscericola<\/jats:italic>is C46<jats:sup>T<\/jats:sup>(=JCM 13660<jats:sup>T<\/jats:sup>=DSM
