As aves têm sido identificadas como reservatórios, atuando como possíveis propagadoras desses micro-organismos. Neste contexto, o trabalho teve como objetivo verificar a ocorrência de Campylobacter spp., Y. enterocolitica e S. enterica em frangos de corte e em aves silvestres, identificar as espécies de aves silvestres presentes na região sul do Brasil e quais podem ser portadoras de patógenos, pesquisar a presença dos genes cdtA, cdtB e cdtC nos isolados de Campylobacter e identificar os sorotipos de Salmonella encontrados. As aves silvestres foram capturadas próximas a lavouras de arroz e aviários com redes de neblina e soltas após a coleta. Amostras de fezes, 200 de frangos e 214 de aves silvestres de várias espécies, foram coletadas diretamente da cloaca com uso de zaragatoas e processadas para pesquisa de Campylobacter spp., S. enterica e Y. enterocolitica. Campylobacter spp. foi isolado de Chrysomus ruficapillus (Garibaldi) e Zonotrichia capensis (Tico-tico), e Salmonella isolada de Sicalis flaveola (Canário-da-terra). De frangos foram isolados Campylobacter spp., S. enterica e Y. enterololitica. Os mesmos micro-organismos foram isolados de fezes de frangos e aves silvestres capturadas no entorno dos mesmos aviários, sugerindo que ocorra uma contaminação mutua entre os dois grupos de animais. / Campylobacter jejuni, Salmonella enterica and Yersinia enterocolitica are among the most commonly microorganisms associated with food intoxication involving the consumption of animal products. The birds have been identified as reservoirs, acting like possible propagators of these microorganisms. In this context, the study aimed to verify the occurrence of Campylobacter spp., Y. enterocolitica and S. enterica in broilers and wild birds, identify the species of wild birds present in south Brazil and which may harbor pathogens, search the presence of genes cdtA, cdtB and cdtC in isolated Campylobacter and identify serotypes Salmonella found. Wild birds were captured near rice fields and aviaries with mist nets and released after collection. Faeces samples, 200 of broilers and 214 of wild birds, were collected directly from the cloaca using swabs and processed for Campylobacter spp., S. enterica and Y. enterocolitica research. Campylobacter spp. was isolated from Chrysomus ruficapillus (Garibaldi) and Zonotrichia capensis (Tico-tico), and Salmonella isolated from Sicalis flaveola (Canário-da-terra). Campylobacter spp., S. enterica and Y. enterololitica were isolated from broilers. The same microorganisms were isolated from broilers and wild birds faeces captured in the vicinity of the same aviaries, suggesting a mutual contamination between the two groups of animals.
