Abstract

Fifty cases of dermatomycoses were recorded from adult male and female at Qena Gvernorates.These included tinea capitis (62% of total cases), tinea corporis (20%), tinea versicolor (12%) and tinea unguium (6%). Males are more susceptible to all cases of tinea than females. Thirty-one species and 2 varieties belonging to 16 genera were recovered from several infection sites. These were identified as Aphanoascus fulvescens, A. terreus, Arthroderma fulva, A. obtusa, Trichophyton rubrum and T. soudanense. Several saprophytes were also found. These were : Aspergillus flavus, A. fumigatus, A. niger, A. terreus, Cochliobolus lunatus, Mycosphaerella tassiana, Penicillium chrysogenum and P. citrinum. Twenty-one isolates were able to hydrolyze gelatin with variable capabilities. T. rubrum was the most active protease producer. The maximum production of protease was obtained at 8 days of incubation at 30degrees C in Sabouraud's basal medium with maltose as a carbon source and pepton as a nitrogen source. The optinal pH for the maximum production of protease was pH 6.
