Abstract
Background: Dermaptophytes are dimorphic fungi which cause infections on skin, hair and nail. Dermatophytoses is an important health problem in both developed and developing countries.
Aim: To study about the dematophytic infections in different age groups of patients and to find out the common forms and isolates causing dermatophytoses in a rural tertiary care hospital.
Method: Samples from the actively infected patches of the patients were subjected to potassium hydroxide mount and culture on Sabouraud’s dextrose agar. The colonies after sufficient growth were taken for wet mount preparation using Lactophenol Cotton Blue solution and the etiological agents were identified. Species identification is further confirmed based on pigment production on Cornmeal agar (CMA).
Result: A total of 112 positive samples were studied in which 71 were males and 41 were females. Tinea corporis and tinea cruris were isolated the most which is followed by lower percentage of other dimorphic fungi like tinea capitis, tinea faciei, tinea manuum and tinea pedis. Age group of 21-30 were found out to be affected more than other age groups. Trichophyton rubrum and Trichophyton mentagrophytes were the maximum isolated species. One case of Epidermophyton floccosum is also isolated.
Conclusion: Dermatophytic infections were found out to be more prevalent in males than females with a predominance of tinea corporis and tinea cruris. 21-30 years were the predominant age groups to have the infection. Trichophyton rubrum is the commonly isolated species.
Keywords: Dermatophytes, Dermatophytoses, Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum.
