MARTINS, Clélia Aparecida de Paiva; KOGA-ITO, Cristiane Yumi  e  JORGE, Antonio Olavo Cardoso. Presence of Staphylococcus spp. and Candida spp. in the human oral cavity. Braz. J. Microbiol. [online]. 2002, vol.33, n.3, pp. 236-240. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822002000300009.

The presence of yeasts and staphylococci in the oral cavity is important because they can act as supplementary microbiota and in certain situations can cause oral or systemic diseases. The aim of this work was to study the prevalence of Candida spp. and Staphylococcus spp. in the human oral cavity. Oral rinses were collected from sixty-eight individuals according to the technique described by Samaranayake and MacFarlane and then cultured on Sabouraud medium supplemented with chloramphenicol and Baird-Parker agar. After the incubation period, the microorganisms were isolated and identified through biochemical tests. The data obtained were statistically analysed by ANOVA. Candida spp. were isolated from 61.76% of the examined individuals and C. albicans was the more frequently isolated specie. Staphylococcus spp. were isolated from 95.60% of the individuals and 41 strains were coagulase negative (63%). Among the coagulase positive strains, nine were S. aureus, 11 S. hyicus and 4 S. schleiferi subspecie coagulans. No correlation was observed between the counts (cfu) of the isolated Candida spp. and Staphylococcus spp.
