Prevalence of dermatophytoses in the Zarqa district of Jordan

A total of 350 clinically suspected cases of dermatomycoses were examined for causative fungi during July 1997 to September 1998. Mycotic infection was demonstrable by microscopy and culture in 199 (56.8%) cases. The most common superficial mycotic infections were tinea pedis (35.2%) followed by tinea capitis (23.1%), tinea unguium (21.6%) and tinea corporis (10.6%). Most of the infected patients were 1-9, 20-29 and 30-39 years old. Men were mainly infected with tinea cruris and tinea pedis, while women were infected with tinea pedis, tinea unguium and tinea capitis. The frequencies of etiological agents isolated from patients were as follows: Trichophyton mentagrophytes var. interdigitale (32.7%), T. rubrum (28.6%), Epidermophyton floccosum (20.1%), Microsporum canis (11.1%), T. schoenleinii (4%), T. verrucosum (2%), T. violaceum (1%), and M. gypseum (0.5%). The number of infections varied with the seasons. The highest number of cases of tinea pedis and tinea cruris occurred in the summer months, while tinea capitis, tinea corporis and tinea unguium occurred in the spring and winter months.
