The occurrence of keratinophilic fungi in sewage sludge from Egypt.

The keratinophilic fungi of 40 sewage sludge samples from Upper Egypt were studied using a goat hair-baiting technique. 43 species representing 22 genera were isolated, 17 species of which were dermatophytes and closely related fungi: Chrysosporium state of Arthroderma tuberculatum, C. asperatum, C. georgii, C. indicum, C. keratinophilum, C. pseudomerdarium, C. queenslandicum, Chrysosporium state of Thielavia sepedonium, C. tropicum, Microsporum cookei, M. gypseum, Myceliophthora anamorph of Corynascus novoguineensis, M. vellerea and Trichophyton terrestre. 26 species of cycloheximide resistant fungi were collected and these included members of Acremonium, Aspergillus, Alternaria, Chaetomium, Cladosporium, Cunninghamella, Emericella, Fusarium, Geotrichum, Penicillium and others.
