[Contribution to the study of dermatomycosis in Catalonia].

We report the results of a study which aim was the mycological identification of specimens coming from patients included in a clinical trial. A total of 445 specimens from patients with clinical diagnosis of dermatomicosis were processed during 8 months (138 pityriasis versicolor, 28 cutaneous candidosis and 279 dermatophytosis). A 48% of pityriasis versicolor cultures were positive for Malassezia furfur, 50% of candidosis cultures were positive for yeasts and 67% of dermatophytosis cultures were positive for dermatophytes. According to our results Candida albicans was the principal causative agent for cutaneous candidosis and Trichophyton mentagrophytes and Trichophyton rubrum were the most frequent isolated species causing dermatophytosis.
