Four Gram-stain-positive, catalase-negative, coccoid-shaped organisms were isolated from elephant oral cavities. The isolates were tentatively identified as streptococcal species based on the results of biochemical tests. Comparative 16S rRNA gene sequencing studies confirmed the organisms to be members of the genus Streptococcus. Two isolates (NUM 6304T and NUM 6312) were related most closely to Streptococcus salivarius with 96.8% and 93.1% similarity based on the 16S rRNA gene and the RNA polymerase β subunit encoding gene (rpoB), respectively, and to Streptococcus vestibularis with 83.7% similarity based on the 60 kDa heatshock protein gene (groEL). The other two isolates (NUM 6306T and NUM 6318) were related most closely to S. vestibularis with 97.0% and 82.9% similarity based on the 16S rRNA and groEL genes, respectively, and to S. salivarius with 93.5% similarity based on the rpoB gene. Based on phylogenetic and phenotypic evidence, these isolates are suggested to represent novel species of the genus Streptococcus, for which the names Streptococcus loxodontisalivarius sp. nov. (type strain NUM 6304T=JCM 19287T=DSM 27382T) and Streptococcus saliviloxodontae sp. nov. (type strain NUM 6306T=JCM 19288T=DSM 27513T) are proposed.
