Dermatophyte infections in the Ljubljana region, Slovenia, 1995-2002

We studied dermatophyte infections in patients, examined in the Mycological Laboratory of the Department of Dermatology, University Medical Centre Ljubljana during the period 1995-2002. A total of 42 494 samples were collected from 33 974 patients suspected to have dermatomycosis. Dermatophytes were identified in 8286 (71.2%) positive cultures. Microsporum canis was the most frequent dermatophyte isolated (46.8%), followed by Trichophyton rubrum (36.7%), T. mentagrophytes var. interdigitale (7.9%) and T. mentagrophytes var. mentagrophytes (4.9%). Less frequently isolated were M. gypseum, T. verrucosum, Epidermophyton floccosum, T. tonsurans and T. violaceum. The most common dermatophyte infections included tinea corporis, onychomycosis, tinea pedis and tinea faciei. Zoophilic dermatophytes were most commonly recovered from children and adolescents with tinea capitis, tinea corporis and tinea faciei. Anthropophilic species were identified mostly in adults with tinea pedis, onychomycosis and tinea inguinalis. During the period studied, we recorded a decline in the rate of M. canis infections, while infections produced by T. rubrum increased in frequency.
