Four mature ewes developed mild neurological symptoms. Histological examination revealed a nonsuppurative encephalitis and myelitis associated with protozoan cysts identified as Sarcocystis spp. by immunoperoxidase. The mild clinical signs and apparent recovery of 1 ewe suggest that neurological disease caused by Sarcocystis spp. may be more common than indicated by the infrequency of reports.
四只成年母羊出现了轻微的神经症状。组织学检查显示为非化脓性脑炎和脊髓炎,伴有通过免疫过氧化物酶鉴定为肉孢子虫属的原生动物囊肿。一只母羊的轻微临床症状及明显恢复表明,肉孢子虫属引起的神经疾病可能比报告的罕见情况所显示的更为常见。
