Lawson p.a.lawson{at}reading.ac.uk Morphological, biochemical and molecular genetic studies were carried out on an unknown non-spore-forming, Gram-negative, rod-shaped bacterium which was isolated from dog faeces. The bacterium grew under anaerobic conditions, was asaccharolytic, resistant to 20 % (v/v) bile and was oxidase- and urease-negative. Phylogenetic analysis based on comparative 16S rRNA gene sequencing showed that the unidentified bacterium clustered with Sutterella wadsworthensis , although a sequence divergence of >5 % indicated that the bacterium from dog faeces represented a previously unrecognized subline within the genus. On the basis of the presented findings, a novel species, Sutterella stercoricanis sp. nov., is described. The type strain of Sutterella stercoricanis is 5BAC4 T (=CCUG 47620 T =CIP 108024 T ). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain CCUG 47620 T is AJ566849 .
