title: Dermatophytes and other fungi associated with skin mycoses in Tripoli, Libya.
abstract: This study sought to determine the prevalence of skin infections and their causative agents in the Libyan population. Samples were collected from 2224 patients attending the Dermatology Clinics of the Tripoli Medical Centre (TMC) between August 1997 and December 1999 and were submitted to a mycology laboratory for analysis. Diagnosis was confirmed by microscopic examination in 1180 cases (53.1%) and the causative agent was isolated and cultured in 1160 cases (52.2%). Dermatophytes, Malassezia furfur and Candida albicans were the most common etiological agents isolated. Tinea corporis accounted for 45.9% of cases (85% of cases occurred in children below 15 years of age). The frequency of the other clinical types in descending order was pityriasis versicolor 27.8% (322 cases), candidiosis 13.4% (156 cases), tinea pedis 8.1% (94 cases), tinea manuum 2.6% (30 cases) and tinea barbae 2.2% (26 cases). Trichophyton violaceum was the most common etiological agent, responsible for 44% (300 cases) of dermatophyte infections. Malassezia furfur was ranked the second most frequent causative agent being found in 27.8% of cases, followed by Trichophyton rubrum 13.8% (160 cases) and Candida albicans 10% (116 cases). Other species isolated included Microsporum canis 8.1% (94 cases), Epidermophyton floccosum 6.6% (76 cases) and Trichophyton mentagrophytes 3.1% (36 cases).
