In the bibliography, the most observable genre is Candida and less frequently found are other opportunistic such as Aspergillus, Rhizopus, Cryptococcus, and others. The authors determined the presence of fungi in the oral cavity of IC students, and their relationship with the concentration of secretory IgA in saliva. To this end, we collected 50 samples of oral cavity swabs, which underwent direct examination and culture in Sabouraud dextrose agar with chloramphenicol. For its identification, CHROMagar Candida and API Candida （BioMerieux） were used. We obtained nine positive cultures （7 Candida albicans and 2 Saccharomyses cerevisiae）, which represented 18% of the studied population. Throughout radial immunodiffusion （RID plates-PLATE）, we determined the concentration of secretory IgA. No relationship was observed between the colonized group and group that was not colinized. The colonization rate found is below the one described in the bibliography （30% to 50%）. However, these opportunistic fungi cause transitory colonization with no clinical relevance in IC patients and, its percentage can vary according to the studied population.展开更多
