Among the species of genus Streptococcus two members namely Streptococcus ratti and Streptococcus ursoris were isolated from oral cavity of rat and bear, respectively. Type strain of these members shows a 16S rRNA gene sequence similarity of 98.9%. Based on systematic phylo-taxonogenomics investigations, we could deduce the taxonomic assignment of the members of these species. Genome similarity assessment among the type strain of these members using average nucleotide identity (orthoANI and fastANI), digital DNA-DNA hybridization and average amino acid identity (AAI) were 98.5, 98.3, 88, and 98.3% respectively. All these values exceed the species delineation cutoffs suggesting a unified species. Phylogenetic tree obtained using 16S rRNA gene sequence also indicates the monophyletic nature of the member strains. Such monophyletic taxonomic positioning of the strains was further complemented with the whole genome-based phylogenomic tree. Based on these evidences, we propose S. ursoris should be reclassified as a later heterotypic synonym of S. ratti.
