Genetic diversity of oral streptococci in the guinea pig as assessed by sequence analysis of the 16S rRNA and groEL genes.

ABSTRACT: The aim of the present study was to characterize bacteria of the genus Streptococcus isolated from the oral cavity of the guinea pig as well as to assess the significance of these microorganisms as potential veterinary and human pathogens. Sixty-two streptococcal isolates recovered from 27 clinically healthy guinea pigs were examined genotypically by sequencing the 16S rRNA and groEL genes. Among these isolates, only 13 could be assigned to a species described previously (mainly Streptococcus parasanguinis, S. mitis and S. suis), and the majority of the remaining ones differed considerably from the streptococcal species known to date (16S rRNA and groEL sequence similarities were < 97% and < 87%, respectively). Based on 16S rRNA sequences, these unidentified isolates were divided into seve
