IntroductionThe creation of birds may, often exposed to risk from infectious diseases, knowing the fact of free-living birds or captive presenting important role in reserves, circulation and dissemination of micro-organisms potentially pathogenic to man and animals. Additionally, the indiscriminate use of antimicrobial agents (prophylactic and therapeutic) and disinfection products for cages, perches, can lead dissemination of resistance of environmental microorganism. Objectives To evaluate the occurrence and distribution of yeasts in feces of Serinus canarius domesticus and to know their antifungal susceptibility profile. Methods November 2011 to April 2012, feces 20 samples from canaries (captive birds), were cultured for fungi. Mycological analyses occurred at the Microbiology Laboratory from Medical School of São José do Rio Preto (FAMERP). Biochemical and commercial tests- ID 32C (BioMerieux) were performed to define the yeast species. The evaluation of the antifungal activities of Fluconazole, Itraconazole, Ketoconazole and Amphotericin B followed according to disk diffusion M44-A2 and microdilution M27-A3 methods (CLSI). Results Yeasts occurred in 80% (N=16) which were recovered from 20 samples. High diversity of species were detected (29): Rhodotorula mucilaginosa (8), Candida parapsilosis (3), Candida famata (2), Cryptococcus albidus (2), Cryptococcus laurentii (2), Kodamaea ohmeri (2), Trichosporon mucoides (2), Candida membranifaciens (1), Sporobolomyces salmonicolor (1), Candida guilliermondii (1); Candida tropicalis (1), Cryptococcus curvatus (1), Cryptococcus neoformans (1), Cryptococcus unigulatus (1), Trichosporon asahii and Rhodotorula glutinis (1). Considering species-specific groups, the profile of resistance and dose-dependent susceptibility for Fluconazole and Itraconazole was commonly observed: 7 species to Fluconazole and 5 for Itraconazole. All isolates were susceptible to Amphotericin B and Ketoconazol. Conclusion This study, alert about the need of veterinary supervision for preventive measures in canaries breeding, emphasizing the zoonotic potential of resistant pathogenic yeasts. Considering the worldwide popularity as pet of Serinus canarius domesticus, new surveillance parameters for domestic birds must be create including microbial monitoring of bird dropping.
