BACKGROUND: Superficial fungal infections are common in the tropics, partly due to the climate, relatively poor hygiene, and lifestyle of the people.
OBJECTIVE: To determine the clinical forms and aetiological agents of superficial fungal infections as seen among skin cases in the north- central part of Nigeria.
METHODS: All consecutive new patients seen at the skin clinic of the General Out-patient Department of the Federal Medical Centre, Bida from July 2006 to December 2007 were included in this prospective study. Participants were examined for superficial fungal lesions. Samples of skin scrapings for microbiological investigations were obtained from suspicious lesions.
RESULTS: A total of 381 patients attended the Skin Clinic during the period of study. Superficial fungal infections constituted 89(23.4%) of all skin cases seen. The commonest clinical type of fungal infection was Tinea corporis, followed by Tinea unguium. Male to female ratio of clinical lesions was 1: 1.5. A total of 41 samples grew fungal organisms on Sabouraud Dextrose Agar culture, of which dermatophytes were the isolates in 22(53.7%), while non-dermatophytes accounted for the rest. Seven species of dermatophytes, dominated by Trichophyton spp. 15 (68.2%), followed by Microsporum gypseum 4(18.2%), and Epidermophyton floccosum 3(13.6%) were the main isolates. The most commonly recovered species were T. mentagrophytes (36.4%).
CONCLUSION: These data show the continued predominance of dermatophytes as the principal pathogen in superficial fungal infection. Trichophyton spp. is the predominant class of which T. mentagrophyte is the most prevalent.
