Streptococci were isolated from dental plaque samples collected from 25 animals representing 18 species. Strains were characterized by biochemical, physiological and serological tests. Extracellular polysaccharide‐producing strains of Streptococcus mutans, Str. sanguis and Str. salivarius were found to be confined mainly to primate species. Streptococcus mutans was not widely distributed, being isolated from 2 of 18 animal species. Enterococci were isolated from the mouths of about one‐third of the animals, whilst Str. bovis was found mainly in the herbivores. Strains resembling Str. mitior were isolated from most animals. Of 271 strains. 34 could not be allocated to any known species. Streptococci known to be associated with diseases of animals, especially those belonging to Lancefield group C, were not isolated. A few strains representing Lancefield groups D, L, G and M were found, but with low frequency.
