rDNA-based genotyping of clinical isolates of Candida albicans

Abstract

The study presents an analysis of the restriction pattern of rDNA fragments of 95 C. albicans isolates previously classified on the basis of the presence of the intron in rDNA into genotypes A (62 isolates), B (28), and C (5). Most isolates (61) with genotype A were classified as "subtype a" and one as "subtype d" (Karahan and Akar; 2005). No differences were observed in the restriction patterns of the tested genotype B isolates. Similarly, most genotype C strains (4/5) showed the same restriction pattern. The results indicate low subtyping variations of the analyzed isolates, which is in contrast to published data obtained from a Turkish collection of yeasts.
