Men and animals have an age-old relationship, where the group of birds, in particular, is widely used for various purposes, such as food and company.Men and animals have an age-old relationship, where the group of birds in particular is widely used for various purposes, such as food and company. The birds are portrayed as disseminators of pathogens to the environment, however, knowledge about this role certain avian species, closely correlated to humans, are somewhat scarce. This study aimed to isolate, identify and characterize the phenotype and the genotype obtained yeast stool five captive birds: chicken (Gallus gallus domesticus), Love bird (Agapornis spp), Budgerigar (Melopsittacus undulatus) cockatiel (Nymphicus hollandicus) and canary (Serinus canaria domesticus). Therefore, we evaluated 247 stool samples of these five avian species from seven cities located in the northwest from State of São Paulo, southern of Minas Gerais and southwestern Mato Grosso do Sul. The collection was performed using sterile spatulas. The material was seeded in Sabouraud dextrose agar and seed Niger agar, with titrations. The identification of species was based on biochemical and macro and micromorphological characteristics. In addition, all isolates identified were submitted to antifungal susceptibility testing by disk diffusion (CLSI, M44-A), compared to amphotericin B, ketoconazole, fluaconazole and itraconazole. The occurrence of yeasts occurred in 89% of samples, ranging from 77.5% to 94.0% of the studied independently bird. There were obtained 318 isolates belonging to 29 different species. There were obtained 318 isolates belonging to 29 different species. The prevalent genus isolated was Candida with 183 (57.5%), followed by Cryptococcus with 45 (14.2%), Rhodotorula with 38 (11.9%) and Trichosporon with 36 (11.3%); other genres totaled 16 isolates (5.0%). Note that, in the number of fungal species isolated, C. albicans, C. guilliermondii, C. ...
