  • Mutans streptococci such as Streptococcus mutans and Streptococcus sobrinus have been implicated in human dental caries. (elsevierpure.com)
  • 144 human dental plaque samples were analyzed, and a PCR with primers for 16S rRNA gene was shown to be more sensitive for detecting S. mutans and S. sobrinus than with those for glucosyltransferase and dextranase genes (except for detection of S. sobrinus in ages 0-1). (elsevierpure.com)
  • Utilizing PCR with primers based upon the 16S rRNA gene, S. mutans was detected from all of the samples while the detection frequencies of S. sobrinus were lower (10%) than those of S. mutans, and S. sobrinus were likely detected in the subjects of deciduous attained-dentition and mixed-dentition stage.
