RESUMO
Although Candida albicans is a part of the mycoflora of healthy individuals, it is causing mild to severe forms of candidiasis in patients with underlying diseases. The recent molecular investigations were classified three genotypes, A, B and C for C. albicans. The aim of the present study was to detect different genotypes of C. albicans complex species in a normal population in Iran. Saliva was randomly collected from a normal population, homogenized and cultured on CHROMagar Candida. Classical and molecular methods were used for the detection of isolates. Candida 25S rDNA gene was amplified using the primer pairs of CA-INT-L and CA-INT-R for ABC genotyping of C. albicans. Candida albicans complex was recovered from 103/194 (53·1%) normal papulation. Genotype A with a frequency of 41·7% was the most common isolate, followed by genotype C (34%), genotype B (20·4%) and genotype D (3·9%). Genotyping of C. albicans species complex from healthy individuals showed the presence of three A, B and C genotypes of C. albicans and one D genotype of C. dubliniensis.
