Geophilic dermatophytes and other keratinophilic fungi in the nests of wetland birds

The frequency and species diversity of keratinophilic fungi in 38 nests of nine species of wetland birds were examined. Nine species of geophilic dermatophytes and 13 Chrysosporium species were recorded. Ch. keratinophilum, which together with its teleomorph (Aphanoascus fulvescens) represented 53% of the keratinolytic mycobiota of the nests, was the most frequently observed species. Chrysosporium tropicum, Trichophyton terrestre and Microsporum gypseum populations were less widespread. The distribution of individual populations was not uniform and depended on physical and chemical properties of the nests (humidity, pH)
