Campylobacter spp., Salmonella enterica e Yersinia enterocolitica em aves silvestres e frangos de corte

Abstract

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.
