[Prevalence of superficial mycoses in an urban ecosystem in Sfax (Tunisia)].

The authors studied the epidemiological aspects and the frequency of the various etiological agents of the superficial mycosis found in the region of Sfax, from 1,724 mycologic samples collected during 3 years (1989-1991). The rate of positivity is of 49%. The anthropophile dermatophytic species are often isolated dominated by the Trichophyton rubrum and the Trichophyton violaceum. The fungus of Candida albicans type and Malassezia furfur are the most frequently identified. The frequent localisations are the athlete foot and the onychomycosis where the rate of positivity is beyond 60%. The tinea of scalp are about to 77% due to Trichophyton violaceum, and sporadic form of tinea favosa have been described.
