【 摘 要 】

An outbreak of poisoning by Senna occidentalis in wild boars in Goiás, Brazil, is described. Out of 80 wild boars, 15 were affected and one died. Clinical signs included apathy, muscle tremors, incoordination, reluctance to move, sternal or lateral recumbence, and paresis and spastic paralysis, especially in the hind limbs. Gross lesions were characterized by moderate to severe paleness of the skeletal muscles of the hind and thoracic limbs and loin, and were marked in the thigh muscles. Histologically, a monophasic, mild to moderate, multifocal floccular muscle degeneration and necrosis with skeletal fiber sarcoplasmic fragmentation was observed. In transverse sections there were multiple swollen and hypereosinophilic muscle fibers. In addition, mild to moderate, diffuse microvacuolar degeneration was seen in the liver. Creatine phosphokinase serum activity was severely elevated in two evaluated wild boars. In one of them, there was elevation of glutamic oxaloacetic transaminase serum activity. Index
