随着免疫生化技术的进展，在血吸虫病诊断方面，普遍采用血吸虫虫卵作为抗原，制作诊断试剂，因此，虫卵的需要量越来越大。几十年来，国内外分离日本血吸虫虫卵普遍采用将感染家兔肝脏搞碎、过筛、沉淀、离心及过滤五步的传统方法。此方法操作步骤复杂，分离速度慢，虫卵得量 With the progress of immunobiochemical technology, Schistosoma japonicum eggs are commonly used as antigens in the diagnosis of schistosomiasis, making diagnostic reagents. Therefore, the requirements of eggs are getting larger and larger. For decades, domestic and international isolation of Schistosoma japonicum eggs commonly used in rabbits infected liver, broken, sieved, precipitation, centrifugation and filtration of five traditional methods. This method is complicated operation steps, the separation speed is slow, the amount of eggs
