Resumo
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,
lank 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.
