Abstract :
Due to the epidemiological alteration in distribution of Candida species as well as significant increasing trend of either intrinsic or acquired in resistance of some of these fungi, the precise identification of Candida species is necessary for effective antifungal therapy and also for prevention of nosocomial infections. PCR-RFLP method is indicated to be a reliable, rapid and simple technique which is able to differentiate the Candida species. In the present study, we applied this method to evaluate the distribution of Candida species in patients affected with cutaneous candidiasis in the Guilan province. 896 clinical cutaneous samples were collected from different parts of skin and nail of suspected patients referred to clinical centers all over the Guilan province during 24 months. Samples were examined directly with 15% KOH and cultured on fungal specific media. Genomic DNA was extracted and the restriction enzyme Msp1 was applied for polymorphism analysis. Totally, 47 yeast strains were successfully isolated from different clinical samples and identified by conventional as well as PCR-RFLP methods. The results indicated that Candida albicans (36.17%) was the most frequent species followed by C. parapsilosis (25.53%), C. tropicalis (19.14%), C. guilliermondii (14.89%), C. famata (2.12%) and C. krusei (2.12%). Female finger nails were the most common location to be affected by Candida species. In conclusion, PCR-RFLP method was successfully used for recognition of clinical Candida species within the Guilan province and obtained results revealed C. albicans as the predominant causative agent of cutaneous candidiasis. However, distribution of other Candida species did not completely consist with the reported distribution of Candida species in other parts of Iran with different climate to the Guilan province.
