Abstract

A facultative anaerobic, non-motile, non-spore-forming, Gram-positive-staining, coccus-shaped bacterium was isolated from an abscess on the right foot of a chimpanzee (). The colonies were β-haemolytic. Catalase and oxidase activities were negative. The Lancefield group B antigen was expressed. On the basis of morphological and biochemical characteristics, the bacterium was tentatively identified as a streptococcal species. 16S rRNA gene sequence analysis indicated that the bacterium shared 96.7 %, 96.4 %, 96.1 %, 95.8 % and 95.7 % sequence similarities with , , , and respectively. Phylogenetic analyses based on the sequences of the 16S rRNA gene and housekeeping genes encoding -alanine : -alanine ligase (), the β-subunit of RNA polymerase () and manganese-dependent superoxide dismutase ( revealed that the bacterium represented a novel species closely related to, albeit different from, , and the anginosus streptococci. The name sp. nov. is proposed. The type strain is M09-11185 ( = ATCC BAA-2337 = KCTC 33006).
