Distribution of keratinophilic fungi in animal folds in Kuwait.

Soil samples from seventeen animal herds (camels, goats, sheep, cows) were surveyed for the occurrence of keratinophilic fungi. Twenty four species related to eleven genera were recovered on defatted wool baits. Eleven Chrysosporium species were reported in the following order of dominance: C. keratinophilum, C. tropicum, C. indicum, C. queenslandicum, C. pannicola, C. carmichaelii, C. state of Arthroderma curreyi, C. zonatum, C. state of A. cuniculi and Chrysosporium state of Renispora flavissima. The Aphanoascus teleomorph of C. keratinophilum, C. indicum and C. tropicum were frequently reported in soils from cow and sheep folds. Scopulariopsis, Cephaliophora and Sepedonium, although not keratinolytic, were also recorded on wool baits of soils from cow herds which are slightly acidic. The frequency and distribution of these fungi are discussed in relation to animal species and the general ecological conditions of desert soils.
