RESUMO
Em junho de 2007, uma mortalidade de bovinos com sinais clínicos e lesões de insuficiência hepática aguda em uma propriedade, na região da encosta da serra do Rio Grande do Sul, foi atribuída ao consumo de Cestrum intermedium. De um total de 17 bovinos, dois morreram com curso clínico inferior a 12 horas, apresentando tremores musculares, andar cambaleante, reações agressivas, decúbito lateral e morte. À necropsia, o fígado estava moderadamente aumentado de volume e com acentuação do padrão lobular. Histologicamente, o fígado apresentava necrose de coagulação centrolobular, difusa, aguda e acentuada. As alterações patológicas associadas à presença e a evidência de consumo da planta pelos bovinos permitiram o diagnóstico.(AU)
ABSTRACT
In June of 2007, mortality in cattle with clinical signs and lesions of acute hepatic insufficiency on a farm located in the hillside of Rio Grande do Sul mountain range was attributed to Cestrum intermedium consumption. From 17 bovines, two died up to 12 hours presenting clinical signs such as muscular tremors, incoordination, aggressiveness, lateral recumbence and death. Macroscopic lesions were found primary in the liver and were characterized by a slightly increased volume and diffuse accentuation of the lobules. Microscopically, the liver showed diffuse and accentuated centrilobular coagulative necrosis. The presence of Cestrum intermedium plants that was being ingested by the bovine associated with the hepatic lesions was decisive for the diagnosis.(AU)
