ABSTRACT: Soil is the main environment where most fungi occur and is of great importance for their biological activities. This habitat especially houses keratinophilic fungi, which are part of a group of microorganisms capable of producing enzymes that degrade keratin, especially dermatophytes, mycosis agents in humans and animals, some of which are responsible for opportunistic infections. Based on the above, this study aimed to detect the occurrence of keratinophilic fungi in soil of enclosures that house wild mammals. For this, 395 soil samples were collected from the Parque Estadual de Dois Irmãos (PEDI), located in the city of Recife - PE. The samples were processed using the soil suspension technique and cultured in Petri dishes containing Sabouraud Dextrose Agar plus chloramphenicol. The identification of the filamentous fungi was carried out through microculture in lamina, based on the observation of macro and micromorphological characteristics of the colonies. As a result, 233 Colony Forming Units (CFU) were obtained, of which 85 (36.5%) came from the soil that harbored mammals of the order Carnivora, followed by 84 CFU (36%) on soil of mammals of the order Primates. Regarding the identified fungi, there was a higher occurrence of Microsporum gypseum with 123 CFU (52.8%), followed by Chrysosporium sp. with 28 UFC (12.0%) and Fusarium sp. with 10 UFC (4.30%). Animals that live in contaminated enclosures can be asymptomatic carriers of many fungal diseases, acting on the transmission to other animals and humans. As a preventive way, there is an improvement in hygienic and handling conditions. KEYWORDS: fungi, dermatophytes, mycoses, wild animals.
