Proposal of two novel species, <i>Allocoprococcus similis</i> gen. nov., sp. nov. and <i>Faecalimonas hominis</i> sp. nov., isolated from human faeces and genome-based reorganization of the genus <i>Coprococcus</i>.

ABSTRACT: The obligately anaerobic, Gram-stain-positive coccobacilli strains OB7620^T and OB7656^T were isolated from faecal samples of healthy Japanese volunteers. Strain OB7620^T showed the highest 16S rRNA gene sequence similarity to Coprococcus comes ATCC 27758^T (98.4%) and Clostridium nexile DSM 1787^T (96.3%). Strain OB7656^T showed the highest 16S rRNA gene sequence similarity to 'Gluceribacter canis' NATH-2371^T (97.7%), C. nexile DSM 1787^T (94.8%) and Faecalimonas umbilicata EGH7^T (94.8%). These findings indicate that the two strains represent novel species. Genomic analysis clarified the phylogenetic relationship of C. comes with the species cluster designa
