Anaerotruncus colihominis gen. nov., sp. nov., from human faeces Lawson, Paul A. and Song, Yuli and Liu, Chengxu and Molitoris, Denise R. and Vaisanen, Marja-Liisa and Collins, Matthew D. and Finegold, Sydney M.,, 54, 413-417 (2004), doi = https://doi.org/10.1099/ijs.0.02653-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Phenotypic and phylogenetic studies were performed on two isolates of an unidentified Gram-positive, anaerobic, non-spore-forming, rod-shaped bacterium that was isolated from human faeces. The organisms were catalase-negative, produced acetic and butyric acids as end products of metabolism and possessed a DNA G+C content of approximately 54 mol%. Comparative 16S rRNA gene sequencing demonstrated that the two isolates were related closely to each other and formed a hitherto unknown sublineage within the Clostridium leptum rRNA cluster of organisms. Based on phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium should be classified in a novel genus as Anaerotruncus colihominis gen. nov., sp. nov. The type strain of Anaerotruncus colihominis is WAL 14565T=CCUG 45055T=CIP 107754T., language=, type=
