Tinea capitis in Basrah, Iraq.

Tinea capitis is the most common type of dermatophytosis constituting 35.2% (173/491) of all cases of dermatophytosis seen at two out-patients dermatological clinics of the Basrah General Hospital and at two private dermatological clinics between October 1994 and December 1995. Males were more commonly affected than females represented by 60 and 40%, respectively. Out of 173 mycologically positive cases, 143 specimens were culture-positive, represented by five dermatophyte species; Trichophyton violaceum was the most frequent causative agent (38.5%), followed by Trichophyton verrucosum (28.7%), Microsporum canis (26.5%), Trichophyton mentagrophytes var. mentagrophytes (5.6%) and Microsporum gypseum (0.7%). Six atypical cases appeared as cases of seborrheic dermatitis or dandruff and were proved to be atypical cases of tinea capitis caused by T. violaceum.

Characteristics of dermatophytoses in Basrah, Iraq.

A total of 1199 clinical specimens were collected from 1144 patients clinically diagnosed as cases of superficial cutaneous mycoses in Basrah (Iraq). The collected specimens were examined for the etiologic agents of dermatophytoses by direct microscopy and culture. A total of 237 isolates representing eight species of dermatophytes as a causative agents of skin and nails infections were isolated. Among the tinea infections, tinea corporis and tinea cruris were the most common types of dermatophytoses revealed in this study.

Extracellular enzyme activities of dermatophytes and yeast isolates on solid media.

A total of 123 isolates of 14 species of dermatophytes and yeasts were screened for the activity of five extracellular enzymes including elastase, keratinase, protease (gelatinase), lipase and phospholipase, by using solid media. The optimal production and activity of each enzyme was determined with regard to different pH and temperatures. Keratinase activity was high with all the tested fungi with exception of Malassezia furfur. Protease (gelatinase) was produced only by dermatophytes. Elastase was secreted by three dermatophytes viz. Microsporum gypseum, Trichophyton mentagrophytes var. mentagrophytes and T. verrucosum, whereas lipase and phospholipase were detected in all the species except T. violaceum.
