Abstract:
120 soil samples collected from various sites of Cairo were processed for the isolation of keratinophilic fungi by "ToKaVa" hair baiting technique. 22 species belonging to 6 genera were isolated viz.: Chrysosporium tropicum, C. indicum, C. keratinophilum, C. queenslandicum, C. merdarium, C. anamorph of Arthroderma curreyi, C. pannicola, C. lobatum, C. anamorph of Renispora flavissima, C. pseudomerdarium, Microascus mangini, Malbranchea gypsea, Ml. State of Uncicarpus reesii, Ml. State of Coccidioides immitis, Microsporum gypseum, Mr. distortum Mr. audouinii, Mr. fulvum, Trichophyton mentagrophytes, T. terrestre, T. verrucosum and Epidermophyton floccosum. The frequency of occurrence of the isolated fungi was determined. Microsporum gypseum, Chrysosporium tropicum and Chrysosporium indicum were the most frequent species recovered from soil. Most species of keratinophilic fungi were isolated from university, public garden and zoo garden. The distribution of the isolates are discussed.
