Three Gram-stain-negative, obligately anaerobic, non-spore-forming, rod-shaped bacteria (strains YIT 12056^T, YIT 12057^T and YIT 12058^T)were isolated from human faeces. These strains were characterized by phylogenetic analyses based on 16S rRNA gene sequence and phenotypic analyses. 16S rRNA gene sequence analyses revealed that strains YIT 12056^T, YIT 12057^T and YIT 12058^T were most closely related to Bacteroides gallinarum, Bacteroides uniformis and Bacteroides intestinalis with approximate similarity values of 96.6, 95.0 and 96.7 %, respectively. The DNA G + C contents were 45.3 (YIT 12056^T), 45.2 (YIT 12057^T) and 43.6 mol% (YIT 12058^T) and major respiratory quinones of all three isolates were menaquinones MK-10 and MK-11. These properties were typical for the genus Bacteroides. Results of the other phenotypic analyses also supported the affiliation of these strains to the genus Bacteroides. The results of 16S rRNA gene sequence analysis, analysis of the major cellular fatty acids and other biochemical tests allowed genotypic and phenotypic differentiation of the strains. Based on these data, three novel species, Bacteroides clarus sp. nov., Bacteroides fluxus sp. nov. and Bacteroides oleiciplenus sp. nov. are proposed. The type strains of B. clarus, B. fluxus and B. oleiciplenus are YIT 12056^T (= JCM 16067^T = DSM 22519^T), YIT 12057^T (= JCM 16101^T = DSM 22534^T) and YIT 12058^T (= JCM 16102^T = DSM 22535^T), respectively.
