Based on phylogenetic analysis and specific phenotypic characteristics, these strains were included within the Bacteroides cluster and were divided into two clusters. Strains from the two clusters showed 16S rRNA gene sequence similarities of 90·4 and 92·7 % to the nearest recognized species, Bacteroides vulgatus. The strains also formed two clusters exhibiting a 16S rRNA gene sequence divergence of approximately 6 %. DNA–DNA hybridization studies confirmed that the two novel strain clusters were distinct from each other. Based on the phenotypic and phylogenetic findings, two novel species, Bacteroides plebeius sp. nov. and Bacteroides coprocola sp. nov., are proposed, each representing one of the two strain clusters. The DNA G+C content of the type strains were 43·9 mol% for B. plebeius (M12T=JCM 12973T=DSM 17135T) and 42·4 mol% for B. coprocola (M16T=JCM 12979T=DSM 17136T).", }
