Comparison of the predominant cultivable microflora in the dental plaque of Macaca mulatta (rhesus) and Macaca fascicularis (cynomolgus).

The predominant cultivable bacteria in the supra-gingival plaque of Old World monkeys were similar to those in human plaque. A significant interanimal species difference was observed in the absolute and relative concentration of specific microbial populations. Streptococcus mutans serotype c was found primarily in rhesus plaque and serotype e in cynomolgus plaque.
