Resumo: | Plants of genus Crotalaria have been reported as poisonous for many species of domestic animals. The aim of this work is to report, for the first time in Brazil, an outbreak of C. incana poisoning. The outbreak took place in Nova América da Colina County, Northern region of Paraná state, Brazil, causing death of 30 Nelore heifers in a herd of 223 animals, between 3 and 5 years old. The animals were grazing on pasture fully infested with C. incana. The main clinical signs were characteristic of hepatic encephalopathy and consisted of blindness, depression, aggressiveness, recumbency and death in 48 hours. Gama-glutamyltransferase, and alkaline phosphatase activities were increased. The main necropsy findings were liver congestion and evident lobular pattern, increased gall bladder volume and mesentery oedema near gall bladder. Histological exams showed hepatic hemorrhagic centrolobular necrosis, megalocitosis and spongiform degeneration in thalamus. Morbidity and lethality rates were, respectively, 13,45% and 100%. Epidemiological, clinical and pathological findings suggest that C. incana poisoning was the cause of illness. |

O objetivo desse trabalho é relatar, pela primeira vez no Brasil, um surto de intoxicação natural por C. incana. O surto aconteceu no município de Nova América da Colina, mesorregião norte pioneiro do estado do Paraná, causando a morte de 30 animais de um lote de 223 novilhas para engorda, entre três e cinco anos de idade, que estavam em um piquete invadido por C. incana. Os bovinos apresentaram encefalopatia hepática caracterizada por cegueira, depressão e agressividade, evoluindo para a morte em 48 horas. A atividade sérica das enzimas gamaglutamiltransferase e fosfatase alcalina estava aumentada. Congestão hepática e padrão lobular evidente, vesícula biliar aumentada e edema no mesentério próximo à vesícula biliar representaram os principais achados de necropsia. Ao exame histológico observaram-se necrose hepática hemorrágica na região centrolobular com megalocitose e áreas de degeneração esponjosa no tálamo. Os índices de morbidade e de letalidade foram 13,45% e 100%, respectivamente. As evidências epidemiológicas, clínicas e patológicas sugerem o diagnóstico de intoxicação por C. incana.UEL2013-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1279110.5433/1679-0359.2013v34n2p823Semina: Ciências Agrárias; Vol. 34 No. 2 (2013); 823-832Semina: Ciências Agrárias; v. 34 n. 2 (2013); 823-8321679-03591676-546Xreponame:Semina.
