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 (Pan troglodytes). The colonies were -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 Streptococcus gordonii, S. cristatus, S. intermedius, S. anginosus and S. constellatus, respectively. Phylogenetic analyses based on the sequences of the 16S rRNA gene and housekeeping genes encoding D-alanine:D-alanine ligase (ddl), the -subunit of RNA polymerase (rpoB) and manganese-dependent superoxide dismutase (sodA) revealed that the bacterium represented a novel species closely related to, albeit different from, S. gordonii, S. cristatus and the anginosus streptococci. The name Streptococcus troglodytidis sp. nov. is proposed. The type strain is M09-11185(T) (=ATCC BAA-2337(T)=KCTC 33006(T)).
