Isolation of dermatophytes and other keratinophilic fungi from surface sediments of the Shatt Al-Arab River and its creeks at Basrah, Iraq

Abstract

Twenty-five sediment samples were taken from randomly selected sites in the Shatt Al-Arab River and its creeks and analysed for dermatophytes and related keratinophilic fungi. The results revealed that out of 25 samples only 13 (52%) yielded dermatophytes and related keratinophilic fungi. A total of nine species in four genera were isolated. The most frequent genera isolated in this study were Chrysosporium and its teleomorph Aphanoascus. The species most frequently found were Aphanoascus fulvescens, A. durus, Chrysosporium crassitunicatum, Chr. keratinophilum and Chr. tropicum (each n = 3). Microsporum was represented by two species, namely M. fulvum and M. gypseum. Trichophyton was represented by one species, T. verrucosum. The occurrence of these fungi illustrates that sediments may act as a reservoir for potentially pathogenic fungi for human and animals.
