title: [Modern taxonomy, classification, and nomenclature of streptococci].
abstract: Comparative analysis of main trends of taxonomy, classification, and nomenclature of prokaryotic organisms and streptococci was performed. Phylogenetic classification of streptococci was thoroughly considered. Original classification of streptococci based on pathogenicity and ecological-epidemiological criteria was proposed for medical purposes. Allocation of groups of pathogenic and opportunistic streptococci, which are recommended to place in III and IV groups of pathogenicity, was substantiated. It was shown that according to ecological-epidemiological criterion streptococci can be referred to agents of anthroponoses, zoonoses, and sapronoses.
