为探明新疆某羊场死亡羊只的病原，本实验对发病羊只进行临床症状观察、病理解剖、显微镜检查及酶联免疫诊断实验等，显微镜观察结果显示视野中央出现节状虫体，囊状结构，酶联免疫斑点反应结果显示细粒棘球绦虫抗原阳性，确诊了本次羊场发病羊是由细粒棘球蚴虫病原感染所致羊肝包虫病，并根据羊场发病情况提出了治疗方法和预防措施。
In order to find out the pathogen of dead sheep in a sheep farm in Xinjiang, the clinical symptoms, pathological anatomy, microscopic examination and enzyme-linked immuno-diagnostic experiments were carried out. The results of microscopic observation showed that there were arthritic bodies in the center of the field of vision, cystic structure and enzyme-linked immunospot reaction. The results showed that Echinococcus granulosus antigen was positive, and confirmed that sheep liver hydatid disease was infected by Echinococcus granulosus; thus treatment and prevention methods were put forward.
