An unknown Gram-positive, catalase-negative, ovoid-shaped bacterium isolated from the submandibular abscess of a rabbit was subjected to a polyphasic taxonomic analysis. Comparative 16S rRNA gene sequencing demonstrated the unknown coccus represents a new subline within the genus Gemella. The unknown isolate was readily distinguished from other recognized members of the genus Gemella, namely Gemella haemolysans, Gemella bergeri, Gemella morbillorum, Gemella palaticanis and Gemella sanguinis, by biochemical tests and electrophoretic analysis of whole-cell proteins. Based on both phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium is classified in the genus Gemella as Gemella cuniculi sp. nov. The type strain is CCUG 42726(T).
