چکیده
Background and Purpose: Dermatophytosis is one of the most common infections of skin, hair, and nails, caused by a group of keratinophilic fungi known as dermatophytes. Species identification of these fungi is of great significance from epidemiological and therapeutic points of view. The objective of the present study was to investigate dermatophytosis and its causative agents in patients, referring to the Central Mycology Laboratory of Yazd University of Medical Sciences, Yazd, Iran. Materials and Methods: In total, ۱۳۹ clinically suspected cases of dermatophytosis were examined during ۱۲ months from February ۲۰۱۴ to February ۲۰۱۵. Skin scrapings were assessed through direct microscopic examinations and culture studies. Dermatophyte isolates were identified based on colony morphology on potato dextrose agar and dermatophyte test medium, nutritional requirements, urease and hair perforation tests, and microscopic characteristics on slide cultures. Results: Dermatophytosis was mycologically confirmed in ۲۶ (۱۸.۷۰%) out of ۱۳۹ cases. Although there was a statistically insignificant difference between male and female subjects, men were dominantly affected. Infection was significantly common in the age group of ≤ ۲۹ years (p < ۰.۰۴۳). The most common clinical manifestation of dermatophytosis was tinea corporis (۶۹.۲%), followed by tinea cruris (۱۵.۴%), tinea manuum (۱۱.۵%), and tinea pedis (۳.۸%). Trichophyton mentagrophytes complex was the main etiologic agent (۳۸.۵%), followed by T. rubrum (۲۳%), T. violaceum (۱۵.۵%), T. verrucosum (۱۱.۵%), Microsporum canis (۷.۷%), and Epidermophyton floccosum (۳.۸%). Conclusion: In comparison with previous research, epidemiology of dermatophytosis has changed in Yazd over the past decades. Therefore, periodical investigations on the epidemiological aspects of this infection are required for efficient control and prevention of this cutaneous dermatophytic disease.کلیدواژه ها
