Abstract
The aim of this study was to genotype Candida albicans strains isolated from various clinical specimens by using CA-INT-R and CA-INT-L primer pairs designed to span the region that includes the site of the transposable group-1 intron in the 25S rRNA gene. A total of 194 C. albicans isolates (28 invasive and 166 noninvasive) were genotyped. The frequencies of genotypes A, B, C and D were found as 51.0, 29.4, 19.1 and 0.5%, respectively. Statistically significant difference was determined between frequency of genotype distribution between invasive and noninvasive isolates (P < 0.001). Genotype C was more prevalent among invasive isolates while genotype A was in noninvasive ones. Furthermore, six different subtypes were determined among genotype A C. albicans isolates by restriction endonuclease analysis using a previously constructed differentiation scheme consisting of HaeIII and MspI digestions. This study demonstrated the genetic diversity of clinical isolates of C. albicans in our hospital.
