Summary A concise list of records of keratinophilic fungi mainly isolated from hair [in mam- mals] or feathers [in birds] of asymptomatic animals or from their nests is given. Their frequency of occurrence and different ecological aspects of the association of keratinophilic fungi with wild vertebrates are also discussed. Key words Keratinophilic fungi, Mammals, Birds

‘Keratinophilic’ (i.e., often occurring on keratinous In the following concise list of records of KF spe- substrates) and ‘keratinolytic’ (keratin-decomposing) cies, the isolates were obtained from hair (in mammals) or fungi should be differentiated. Some keratinophilic fungi feathers (in birds) of asymptomatic animals, unless other- namely do not digest keratin and live off components wise indicated. The paragraph ‘Ref.’ (References) lists other than the keratin of the keratinous structures [1-4]. In published records and the ‘Coll.’ (Collections) additional this review, only the keratinolytic fungi (KF) are treated.
