They each displayed \u226599.9% 16S rRNA gene sequence identity to the uncultured bacterial clone sequence AY738656 designated as <jats:italic>Eggerthella<\/jats:italic>-like vaginal bacterium (ELVB) and shared 100% 16S rRNA gene sequence identity with each other. Studies using molecular bacterial identification have associated ELVB sequences with BV, higher risk for human immunodeficiency virus acquisition and development of pelvic inflammatory disease in women. Given the clinical significance of this bacterium, we characterized the novel bacterium designated DNF00809<jats:sup>T<\/jats:sup> using biochemical, genotypic and phylogenetic analyses. DNF00809<jats:sup>T<\/jats:sup> was a coccobacillus that was non-motile, non-spore forming, asaccharolytic, proteolytic and indole negative. Fatty acid methyl ester analysis for DNF00809<jats:sup>T<\/jats:sup> indicated C<jats:sub>14\u200a:\u200a0<\/jats:sub>, C<jats:sub>16\u200a:\u200a0<\/jats:sub>, C<jats:sub>16\u200a:\u200a0<\/jats:sub> dimethyl acetal and C<jats:sub>18\u200a:\u200a1<\/jats:sub>\n                  <jats:italic>cis<\/jats:italic>9 to be the major fatty acids. Whole genomic DNA G+C content was 46.1 mol%. Phylogenetic and phylogenomic analyses indicate that DNF00809<jats:sup>T<\/jats:sup> represents a novel genus and novel species within the <jats:italic>Eggerthellaceae<\/jats:italic> family.
