ABSTRACT
The aim of this study was to establish oral carriage of Candida and possible factors associated to their virulence in young adults and their relation with local and general situations considered as predisposing factors. Samples were obtained from dorsum tongue in 70 students attending the Faculty of Dentistry (University of Buenos Aires) average age: 23, all in healthy oral conditions. Of these, 21.42
were Candida positive. These samples were seeded in CHROMagar. Candida identification was completed in milk agar and Fungichrom 1. The following species were identified: 11 Candida albicans (C.a), 2 Candida parapsilosis (C.p) and 1 Candida glabrata (C.g). In one case, 2 species (C.a and C.g) were isolated in the same sample. Virulence was determined as adherence capacity by biofilm or in vitro plaque formation and hydrophobicity. Different host factors were analyzed statistically to establish their importance as predisposing factors to allow Candida colonization. Adherence of C.a. was found to be similar in all C.a. strains, whereas significant differences were found between C.a. and C.p. and between C.a. and C.g. Only the antiseptic mouthrinse and the diet were significant among the considered factors.
