Streptococcus dentapri sp. nov., isolated from the wild boar oral cavity.
Four Gram-stain-positive, catalase-negative, coccoid-shaped isolates were obtained from the oral cavities of wild boars and characterized by phenotypic and phylogenetic studies. On the results of biochemical tests, the organisms were tentatively identified as a streptococcal species. Comparative 16S rRNA gene sequencing studies confirmed that the organisms are members of the genus Streptococcus, with Streptococcus equi subsp. equi ATCC 33398(T) as their closest phylogenetic relative (94.7 % similarity). DNA-DNA hybridization analysis showed that the isolates displayed less than 10 % relatedness to Streptococcus equi subsp. equi DSM 20561(T). From the phylogenetic and phenotypic evidence, the four isolates represent a novel species of the genus Streptococcus, for which the name Streptococcus dentapri sp. nov. (type strain NUM 1529(T) =JCM 15752(T) =DSM 21999(T)) is proposed.
