[Occurrence of bacteria in the mouth from genera of Micrococcus, Kocuria, Nesterenkonia, Kytococcus and Dermacoccus].
The aim of the study was to assess the prevalence of different bacteria in the oral cavity. The bacteria were present in the oral cavities of 73 (48.7%) of 150 individuals. Nesterenkonia halobia, the most frequently isolated species, was found in 20 (27%) individuals, Micrococcus luteus in 16 (22%), Kocuria kristinae in 12 (16%), Kocuria varians in 10 (14%), Dermacoccus sedentarius in 9 (12%), Micrococcus lylae in 8 (11%), and Kytococcus nishinomiyaensis in 3 (4%). Mean counts of these microorganisms were relatively low and amounted in log10 CFU/ml saliva for M. luteus 1.87 +/- 0.52, for M. lylae 2.03 +/- 0.39, for N. halobia 2.14 +/- 0.56, for K. kristinae 2.20 +/- 0.69, for K. varians 2.19 +/- 0.67, for K. nishinomiyaensis 1.72 +/- 0.39, and for D. sedentarius 2.27 +/- 0.55. The factor limiting the population sizes of these microorganisms was most probably the antagonistic activity of the bacteria living in oral cavity.
