Two strains, 199^T and 176, of Gram-negative, anaerobic, rod-shaped, non-spore-forming bacteria were isolated during studies of microbiota in human faeces using polyamine-deficient medium. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolated strains belonged to the genus Bacteroides. The G+C content (42.4–43.0 mol%) and major fatty acid composition (anteiso-C_{15 : 0}, 31.8–36.2 %) supported the affiliation of the two strains to the genus Bacteroides. 16S rRNA gene sequence similarities with their closest neighbours, Bacteroides thetaiotaomicron and Bacteroides ovatus, ranged from 94.6 to 96.5 %. DNA–DNA hybridization and phenotypic analysis showed that the two strains belonged to the same species (DNA–DNA relatedness of 89 %) and were distinct from their close relatives, B. thetaiotaomicron and B. ovatus (<23 % DNA–DNA relatedness). On the basis of these data, a novel species of the genus Bacteroides, Bacteroides finegoldii sp. nov., is proposed, comprising the designated type strain 199^T (=JCM 13345^T=DSM 17565^T) and strain 176 (=JCM 13346).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain 199^T is AB222699.

API 20A and API rapid ID 32 A test results, cellular fatty acid compositions, DNA base composition and levels of DNA–DNA hybridization of strains 199^T and 176 and related strains and a maximum-parsimony phylogenetic tree showing the positions of strains 199^T and 176 among representative members of the genera Prevotella, Bacteroides, Porphyromonas and Tannerella are available as supplementary material in IJSEM Online.
