实验室传统的血吸虫保种方法是将血吸虫毛蚴感染螺宿主,然后用螺宿主中逸出的尾蚴感染脊椎动物宿主来维持其生活史。本文作者介绍了一种不用脊椎动物而仅通过在螺蛳宿主中的无性繁殖的血吸虫移植法来维持血吸虫克隆的技术。将血吸虫幼虫从螺宿主分离出来,然后将其移植到另一健康螺蛳内从而不断获得具有正常感染性的尾蚴。本技术以曼氏血吸虫、埃及血吸虫、牛血吸虫、 Laboratory traditional schistosome conservation method is to infection of Schistosoma infection of spiral worm host, and then spiral host estrus cesium infection in vertebrate host to maintain their life history. The authors describe a technique for maintaining a schistosome clonage without the use of vertebrates, but only by asexually transplanted Schistosoma japonicum in a snail host. Schistosoma larvae were isolated from the snail host, which was then transplanted into another healthy snail to continually acquire cercariae with normal infectivity. The technology to Schistosoma mansoni, schistosoma schistosomiasis, bovine schistosomes,
