New bacteriology findings from New York University, College of Dentistry published

Current study results from the report, "Population structure of plasmid-containing strains of Streptococcus mutans, a member of the human indigenous biota," have been published. "There are suggestions that the phylogeny of Streptococcus mutans, a member of the human indigenous biota that is transmitted mostly mother to child, might parallel the evolutionary history of its human host. The relatedness and phylogeny of plasmid-containing strains of S. mutans were examined based on chromosomal DNA fingerprints (CDF), a hypervariable region (HVR) of a 5.6-kb plasmid, the rRNA gene intergenic spacer region (IGSR), serotypes, and the genotypes of mutacin I and II," scientists...
