Zusammenfassung: | Wild animals are hosts and reservoirs to many infectious agents, often unknown to the Scientific Community, which leads to serious health implications for natural and domestic environments. We conducted this research with the objective of diagnosing the occurrence of parasites of medical and veterinary interest in “coleirinhos” captured in the eastern region of the state of Acre, Brazil. We captured the specimens in August and September of 2017 using ornithological nets at the margins of Caeté river. We visually inspected the birds to evaluate the ectoparasites. Subsequently, we collected blood through a brachial vein puncture and rested the individuals in a cloth bag for 30 minutes to collect feces, after which we released them. Results of the visual inspection to detect and identify the ectoparasites were negative. Blood samples revealed the protozoan Haemoproteus sp., and the feces revealed cysts of Entamoeba histolytica and E. coli, oocysts of coccidia and eggs of Davaineidae. Coccidia was the most prevalent (69.2%) and abundant (34.15%) parasite reported. Parasites diagnosed in this study can promote the emergence of secondary infections in S. caerulescens individuals or other animals that are contaminated with these etiological agents, since, when migrating through different biomes of South America, other animal species can come into contact with these agents.
RESUMO: Os animais silvestres são hospedeiros e reservatórios de vários agentes infecciosos, muitas vezes desconhecidos para a comunidade científica, o que leva a sérias implicações na saúde dos ambientes naturais e domésticos. Esta pesquisa teve como objetivo diagnosticar a ocorrência de parasitos de interesse médico e veterinário em “coleirinhos” capturados no leste do Estado do Acre, Brasil. Os espécimes foram capturados nos meses de agosto e setembro de 2017 em redes ornitológicas as margens do Rio Caeté. Para a pesquisa de ectoparasitos, as aves foram inspecionadas visualmente. Após a inspeção, o sangue foi coletado por meio de punção da veia braquial e para coletas das fezes os indivíduos foram postos em descanso em saco de pano por 30min e depois foram soltos na natureza. As fezes, quando presentes, foram coletadas e acondicionadas em recipientes de plástico estéreis. A inspeção visual dos espécimes para detectar e identificar ectoparasitos resultou negativo. Nas amostras sanguíneas foi identificado o protozoário Haemoproteus sp.. Nas fezes foram encontrados os seguintes endoparasitos: c |
