Abstract

Four Gram-positive, catalase-negative, coccoid isolates that were obtained from donkey oral cavities formed two distinct clonal groups when characterized by phenotypic and phylogenetic studies. From the results of biochemical tests, the organisms were tentatively identified as a streptococcal species. Comparative 16S rRNA gene sequencing studies confirmed the organisms to be members of the genus Two of the isolates were related most closely to with 95.6 % similarity based on the 16S rRNA gene and to with 92.0 % similarity based on the 60 kDa heat-shock protein gene (). The other two isolates, however, were related to with 95.0 and 89.0 % similarities based on the 16S rRNA and genes, respectively. From both phylogenetic and phenotypic evidence, the four isolates formed two distinct clonal groups and are suggested to represent novel species of the genus . The names proposed for these organisms are sp. nov. (type strain NUM 1801 = JCM 17942 = DSM 25193) and sp. nov. (type strain NUM 1808 = JCM 17943 = DSM 25137).
