Studies on Dermatophytes Infection
Abstract
-
The authors performed clincial and mycological studies on 185 outpatients who had clinical evidences of tinea cruris (T. cruris) or tinea corporis (T. corporis) and. who had visited the dermatological clinic of Chonnam University Hospital from April to September in 1978. The incidence of T. cruris was 4. 2%, T. corporis 3. 7%, and concurrent infection of T. cruris and T. corporis l. 1% of the 2526 outpatients who visited our clinic during that time. Of the 185 patients, T. cruris was most prevalent among malea, while T. corporis was evenly distributed between both sexes. The age distribution group for T. cruris and T. corporis varied from several months to the eighth decade, but most of them were in their third decade, at an actively working age. Comparing the incidence of urban and rural areas, patients living in urban areas were affected with T. cruris about two times more than those living in rural area but there was little difference regarding T. corporis. Concurrent infection of T. cruris or T. corporis with other dermatophytoses was noted in 42. 2% of the cases. Fatients with T. cruris and tinea pedis (T. pedis) were most, commonly observed, 30. 8%, with T. cruris and T. corporis 28. I r, T, corporis and T. pedis 19. 2Y., and T. cruris and. T. pedis 12. 8% following in order, In etiological studies of T, cruris Trichophyton rubrum (T. rubrum) was most, frequently the causative organism. But Epidermophyton floccosum and Trichophyton. mentagrophytes (T. mentagrophytes) were also commonly isolated. T. corporis was caused most frequently by T. mentagrophytes and T. rubrum, and Microsporum canis (M. canis) and Trichophyton violaceum (T. violaceum) were also isolated. We cultured fungi from each lesion of the 28 patients with concurrent infections of T. cruris and/or T. corporis with other dermatophytoses, and obtained the same causative strains in all lesions of each patient. We presumed concurrent infection of dermatophytosis to frequently be autoinoculation from one part of the body to another, especially in T. pedis which is often the infectious source of T. cruria and/or T. corporis.
