Abstract

Three Gram-negative, anaerobic, rod-shaped bacteria (strains CB40, CB41 and CB42) were isolated from human faeces. Based on phylogenetic analysis and specific phenotypic characteristics, these strains were included in the genus , and 16S rRNA gene sequence analysis indicated that these strains represented a novel species. The strains were most closely related to the type strains of and , with sequence similarities of 93.4 and 89.8 %, respectively. The G+C content of strain CB42 is 44.7 mol%. Major fatty acids were anteiso-C, C, iso-C 3-OH and C 9. On the basis of the data presented, a novel species, sp. nov., is proposed, with CB42 (=JCM 13818=DSM 18228) as the type strain.
