"Mitis group" streptococci are commensal but may play some role in dental caries, septicemia or endocarditis. Rapid genotypic identification would aid studies of dental plaque ecology, or diagnostic use. AP-PCR with 58 unpaired arbitrary primers was used to characterize 7 Streptococcus gordonii, 11 Streptococcus sanguis, 2 Streptococcus crista, 5 Streptococcus parasanguis, 18 Streptococcus oralis, and 36 Streptococcus mitis (22 biovar 1 and 14 biovar 2). S. parasanguis 16S rRNA variable region primer RR2 produced species-specific bands with all S. gordonii and S. sanguis. Human V beta 1 T-cell receptor primer 434 yielded concordant genotypic identification of all phenotypically defined S. crista and S. parasanguis, 83% of S. oralis, and 74% of S. mitis biovar 1. Amplicon patterns for S. mitis biovar 2 were heterogeneous. Findings suggest that primers RR2 and 434 in succession will allow rapid identification of genotypic groups corresponding closely to mitis group species established by phenotype.
