Isolation of keratomycetes from the soil of wild animal cages and enclosures in the zoo of the Parco Nazionale d'Abruzzo, Italy

The keratinophilic fungi present in the soil of wild animal cages and enclosures in the zoo of the "Parco Nazionale d'Abruzzo", at Pescasseroli, Italy were studied. The goal of the investigation was to determine what species of such fungi existed in wild animal habitats in that area and what variation there may be in their frequency in connection with the seasons. The most prevalent fungus was Trichophyton ajelloi, followed in decreasing order by the Chrysosporium species (C. keratinophilum, C. tropicum, C. state of Ctenomyces serratus). The Microsporums were relatively rare. The perfect forms Arthroderma uncinatum, A. quadrifidum, Nannizzia cajetani and Ctenomyces serratus were isolated from plates containing their corresponding imperfect forms. The recurrence of the species present in the soil of each cage and enclosure in April and in July was remarkable.
