Resumo: | Haemoparasites are one of the most important groups of bird parasites, with emphasis on the genera Haemoproteus, Plasmodium, Leucocytozoon and Trypanosoma. Zoos sustain different wild animals and are valuable tools for the education and conservation of species. The conditions of captive animals differ from wild animals, as zoos have sufficient availability of food throughout the year, protection against predators and veterinary care for animals. This study aimed to determine the prevalence of haemoparasites in captive birds of the Sabiá Municipal Park Zoo, municipality of Uberlândia, state of Minas Gerais, Brazil. Blood samples were collected from the alveolar vein puncture to make blood swabs. This material was fixed with methanol, stained by the GIEMSA technique and examined under optical microscope. A total of 46 birds (19 species) were analyzed and only three individuals (6.52%) were positive for Plasmodium sp. The hosts were Pavo cristatus and Tyto furcata. This low positivity was expected, since haemoparasites do not generally present high infection rates among birds. Even if a parasite is not pathogenic for a given species, these individuals are important reservoirs for the infection of more vulnerable species. Differences in the prevalence and intensity of infection of these hosts depend on the virulence of the parasite, ability of the host to respond to such infections and vector availability. This low prevalence rate suggests a good health status of the captive birds in the study area. |

Os zoológicos contêm diferentes grupos de animais silvestres e são importantes na educação e conservação das espécies. As condições dos animais em cativeiro diferem dos animais silvestres, pois nos zoológicos há disponibilidade suficiente de alimentos durante todo o ano, proteção contra predadores e cuidados veterinários para os animais. O objetivo deste estudo foi determinar a positividade de hemoparasitos em aves de cativeiro no Zoológico do Parque Municipal do Sabiá (Uberlândia, MG). Amostras de sangue foram coletadas, a partir da punção da veia alar, para a confecção de esfregaços sanguíneos. Esse material foi fixado com metanol, corado pela técnica de GIEMSA e examinado ao microscópio óptico. Foram analisadas 46 aves (19 espécies) e apenas três indivíduos (6,52%) foram positivos para Plasmodium sp. As espécies parasitadas foram Pavo cristatus e Tyto furcata, não sendo observados sinais clínicos de doenças nestas aves. Essa baixa positividade era esperada, uma vez que os hemoparasitos geralmente não apresentam altas taxas de infecção entre as aves. Mesmo que um parasito não seja patogênico para uma dada espécie, estes indivíduos são reservatórios importantes para a infecção de espécies mais vulneráveis. Diferenças na prevalência e intensidade da infecção desses hospedeiros dependem da virulência do parasito, habilidade do hospedeiro em responder a tais infecções e disponibilidade de vetores. A baixa parasitemia e o quadro clínico das aves pesquisadas evidencia o bom estado de saúde do plantel do zoológico pesquisado.EDUFU2021-01-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4781810.14393/BJ-v37n0a2021-47818Bioscience Journal ; Vol. 37 (2021): Continuous Publication; e37011Bioscience Journal ; v. 37 (2021): Continuous Publication; e370111981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/47818/30904Brazil; ContemporaryCopyright (c) 2021 Lívia Mendonça de Aguiar, Oswaldo Marçal Júniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAguiar, Lívia Mendonça deMarçal Júnior, Oswaldo2022-05-25T13:40:08Zoai:ojs.www.seer.ufu.br:article/47818Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-05-25T13:40:08Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
