Resumo: Enteric infections account for considerable economic losses to the poultry industry through weight loss, low food conversion, direct and indirect expenses with treatments and increased death rates. Poultry intestinal pathologies, either with local or general manifestations, can be caused by bacteria, protozoa or virus, acting alone or in association. Regarding viral etiology, several genera have been isolated from poultry with enteric disease. However, two genera from the Reoviridae family, the rotavirus and the reovirus are found more frequently in broiler chicken and/or laying hen feces. These viruses have been associated with clinical signs of enteritis in most epidemiological research. This revision aims to present some topics on the etiological agents (rotavirus, reovirus and picobirnavirus), the clinical disease and the diagnostic and control methods and prophylaxis of the infection.

As patologias intestinais em aves, tanto com manifestação local quanto geral, podem ser determinadas por bactérias, protozoários e vírus, atuando de forma isolada ou em associação. Com relação a etiologia virai, vários gêneros têm sido isolados a partir de aves com enteropatias. Porém, dois gêneros na família Reoviridae, o rotavírus e o reovírus são encontrados com maior freqüência em fezes de frangos de corte e/ou galinhas poedeiras. Na maioria dos inquéritos epidemiológicos esses vírus estão associados a sinais clínicos de enterite. Esta revisão tem por objetivo apresentar alguns tópicos relativos aos agentes etiológicos (Rotavírus, Reovírus e Picobirnavírus), à doença clínica e aos métodos de diagnóstico, controle e profilaxia da infecção.  UEL2000-01-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/496510.5433/1679-0359.2000v21n1p101Semina: Ciências Agrárias; Vol. 21 No. 1 (2000); 101-113Semina: Ciências Agrárias; v. 21 n. 1 (2000); 101-1131679-03591676-546Xreponame:Semina.
