Musculature from 198 Canadian cattle with suspected lesions of eosinophilic myositis were examined histologically and by pepsin digestion. Sera from 51 of the 198 animals were also examined by enzyme-linked immunosorbent assay (ELISA) for anti-Trichinella antibodies. Viable larvae of Trichinella were not recovered from any of the cattle but one animal from Ontario tested positive for anti-Trichinella antibodies. Histologically, focal and/or diffuse eosinophilic myositis lesions were observed in 149 (75.2%) of the animals studied. Other conditions identified were sarcocystiosis, abscesses, cysticercosis, steatosis, fibrosis, granuloma, lymphosarcoma and necrosis. Sarcocystiosis was identified in 105 of the 198 animals in both normal and affected musculature. The study indicates that trichinosis is not a primary cause of eosinophilic myositis in cattle.
对198头疑似患有嗜酸性肌炎病变的加拿大牛的肌肉组织进行了组织学检查和胃蛋白酶消化检查。还通过酶联免疫吸附测定（ELISA）对这198头牛中51头的血清进行了抗旋毛虫抗体检测。在任何一头牛中均未发现活的旋毛虫幼虫，但安大略省的一头牛抗旋毛虫抗体检测呈阳性。组织学检查发现，在149头（75.2%）被研究的动物中观察到局灶性和/或弥漫性嗜酸性肌炎病变。鉴定出的其他病症包括肉孢子虫病、脓肿、囊尾蚴病、脂肪变性、纤维化、肉芽肿、淋巴肉瘤和坏死。在198头牛中，有105头在正常和受影响的肌肉组织中均发现了肉孢子虫病。该研究表明，旋毛虫病不是牛嗜酸性肌炎的主要病因。
