Abstract
The yeasts are widely distributed in our environment, being also normal inhabitants of our bodies. Yeasts are considered to be opportunistic pathogens causing infectious processes ranging from superficial to deep and fatal ones. The knowledge of the normal microbiota can help physicians to obtain
a perspective about the possible source and importance of microorganisms isolated from infections. The
objective of the present study was to determine the presence of yeasts in samples of the oral, vaginal, and
anal mucosae and in fecal samples from apparently healthy individuals or individuals who presented symptoms of fungal infection. The media used for isolation were Sabouraud chloramphenicol agar, Biggy
agar, CHROM agar Candida and Pagano Levin agar. Yeasts were isolated from 40.7% (35/86) of the oral samples, 26.2% (11/42) of the vaginal samples from asymptomatic individuals, 44.8% (13/29) of the vaginal samples from women with vaginal discomfort, from 34.6% (9/26) of the anal samples, and 77.5% (31/40) of the fecal samples. C. albicans was the predominant species in all sample types. Feces presented species
diversity represented by the genera Candida, Saccharomyces, Rhodotorula, Trichosporon, Cryptococcus, and Hansenula nowadays Pichia.
