title: Development of molecular methods for identification of Streptococcus bovis from human and ruminal origins.
abstract: Streptococcus bovis has been identified as a causative agent in humans for a variety of diseases, including endocarditis, meningitis, and septicemia. Identification of S. bovis strains of human origin in clinical settings has been problematic due to variations in biochemical tests as compared to ruminal strains of S. bovis, and other streptococcal species. DNA-DNA hybridization with chromosomal DNA from various S. bovis strains indicates that strains of human origin are different from those of ruminal origin. Specific probes have been designed from S. bovis 16S rDNA gene sequences that differentiate strains of human and ruminal origin by direct hybridization and PCR analyses. These techniques now allow for rapid identification of S. bovis strains for clinical and other scientific investigations.
