We report the first case of non-dermatophytic onychomycosis of the toenail described in Kazakhstan caused by Candida parapsilosis. The biological properties of the strain were studied. C. parapsilosis forms white creamy colonies, smooth with focal wrinkles, and the reversum is light-yellow. The culture of C. parapsilosis is represented by a yeast form, characterized by the presence of round or cylindrical yeast cells with active budding. The strain has a high saccharolytic and urease activity and is indifferent to the sucrose and maltose. The C. parapsilosis strain was sensitive to polyene and azole antifungal agents. The highest sensitivity was found to ketoconazole, itraconazole and nystatin.
