寄生于人体的埃及血吸虫和寄生于反刍动物的牛血吸虫有很近的亲缘关系。由于两者寄生于同一种水泡螺,可存在于同一淡水水体内及尾蚴的形态相似等原因,故难以鉴别某一有水泡螺孳生的水体是埃及血吸虫的传染源、还是牛血吸虫的传染源或是两者共有的传染源。常规的鉴别方法需要特殊的实

Schistosoma japonicum parasitic on the human body is closely related to the bovine schistosome parasitized in ruminants. Because of the two parasitic on the same bubblehead can exist in the same freshwater body and cercariae morphology is similar to other reasons, it is difficult to identify a water bubble spawning water body is the source of infection of schistosomiasis, or the source of infection or bovine schistosomiasis It is the common source of infection between the two. Conventional methods of identification require special facts
