Causative Agents of Superficial Mycoses in Istanbul, Turkey: Retrospective Study

The aim of the present study was to determine the percentage of agents, which can give rise to superficial fungal infections in Istanbul, Turkey. Between 2000 and 2007, the clinical samples collected from 8,200 patients attending the outpatient Dermatology Clinic at Mihrimahsultan Medical Center were examined by direct microscopy and culture. Pathogen fungi were detected in 5,722 of the patients. Of the isolates were 4,218 (74%) dermatophytes, 1,196 (21%) Candida sp., 170 (3%) Malassezia furfur, and 138 (2%) Trichosporon sp. Among the dermatophytes, Trichophyton sp. was the most common isolate followed by Epidermophyton floccosum (243) and Microsporum sp. Among the Candida species, C. albicans (549) was also frequently found. Onychomycosis was the most prevalent type of infection, followed by tinea pedis, tinea cruris, tinea corporis, and tinea capitis. In conclusion, our study showed that the most common isolated agents from superficial infections were T. rubrum being Candida sp. the second most prevalent.
