An outbreak of poisoning by Pterodon emarginatus in cattle in Goiás, Brazil, is described. Eighty four cattle that accidentally consumed the leaves and fruits from a P. emarginatus tree, fallen in a storm, were affected and seven died. Clinical signs included piloerection, flank retraction, marked apathy, prostration, muscle tremors, muzzle dryness, tenesmus, incoordination, reluctance to move, and prolonged sternal recumbency. AST, ALT, and GGT serum activity, and bilirubin levels were markedly increased. Gross lesions included hepatomegaly, multifocal areas of necrosis in the liver, and hemorrhages in the heart, parietal pleura, mesentery, omentum, ruminal serosa, spleen, lung, subcutaneous tissue, and thoracic and intercostal skeletal muscles. Histologically, moderate to severe, massive hepatocellular degeneration and necrosis with moderate bile duct hyperplasia and mild bile stasis were observed. In addition, moderate multifocal vacuolar degeneration in the convoluted renal tubular cells was noted. |
