报告一起盐霉素中毒暴发疫情。在46头西门塔尔小母牛中，有13头在出现不协调、步态僵硬、腹泻、体重减轻、肌肉震颤、运动耐受性降低、呼吸困难和偶尔出现尿色变深后死亡。一些动物被发现死亡或被迫移动时死亡。大体病变基本上包括心肌苍白区、心外膜下水肿、心包积液、胸腔积液、肺充血和水肿，在某些情况下，还有下垂的皮下水肿和肉豆蔻肝。组织病理学改变主要表现为心肌纤维坏死和丢失，并被纤维结缔组织所取代。在首次死亡前约9天，用含6%盐霉素的预混物治疗小母牛的艾美耳球虫病。
An outbreak of salinomycin toxicosis is reported. Out of a lot of 46 Simmental heifers 13 died after presenting incoordination, stiff gait, diarrhea, weight loss, muscle tremors, reduced tolerance to exercise, dyspnea and, occasionally, dark urine. Some animals were found dead or died when forced to move. Gross lesions consisted basically of pale areas in the myocardium, subepicardial hemorrhages, hydropericardium, hydrothorax, pulmonary congestion and edema, and, in some cases, pendent subcutaneous edema and nutmeg liver. Main histopathological changes consisted of necrosis and loss of myocardial fibers which were replaced by fibrous connective tissue. Approximately 9 days before the first deaths the heifers had been treated for eimeriosis with a premix containing 6% of salinomycin.
