Although the frequency of candidal onychomycosis is increasing daily, there is little information in literature about the epidemiology, pathogenesis, and antifungal susceptibility of this dermatological disease. This study aimed to provide information about the epidemiology, pathogenesis, and azole susceptibility of Candida species isolated from patients living in a region with continental climate. After identification of the isolated strains using conventional methods, proteinase and phospholipase activities were determined by a plate method and biofilm-forming ability was determined using the microplate method. Susceptibility of the same species to fluconazole (FLU), voriconazole (VRC), miconazole (MNZ), itraconazole (ITZ), and ketoconazole (KTZ) were determined by microdilution method. The 50 Candida isolates included 23 C. parapsilosis (46%), 13 C. albicans (26%), 4 C. guilliermondii(8%), 4 C.tropicalis (8%), 2 C.krusei(2%), 1 C.lusitaniae (2%), 1 C. sake (2%), and 1 C. kefyr (2%) isolates. The geometric mean (GM) of the minimum inhibitory concentration (MIC) for FLU, KTZ, VRC, MNZ, and ITZ was 0.4 μg/mL, 0.08 μg/mL, 0.08 μg/mL, 0.2 μg/mL, and 0.6 μg/mL, respectively. Proteinase, phospholipase, and biofilm-forming ability were detected in 18%(9/50), 20%(10/50), and 6%(3/50) of the Candida isolates, respectively. We found that the most frequently isolated species is C.parapsilosis. On the basis of the GM values, the most effective azoles are ketoconazole and voriconazole. The isolated Candida species exhibited low phospholipase, proteinase, and biofilm formation activities.
