日本血吸虫寄生于宿主体内，雌雄虫体，不断交配产卵，部分虫卵经肠道随粪便排出体外，构成传染源，另一部分沉积在组织中的虫卵，是引起血吸虫病病理变化的主要原因。日本血吸虫在宿主体内存活时间各地报告不一［1，2]。为了解日本血吸虫在适宜宿主体内的存活时间，本实验以黄 Schistosoma japonicum parasites in the host body, the male and female body, continuous mating spawning, part of the egg by the intestine with the excreted excreted, constitute the source of infection, the other part of the deposited in the organization of eggs, is the main cause of pathological changes in schistosomiasis . Schistosoma japonicum in the host body survival time reported around the different [1,2]. In order to understand the survival of Schistosoma japonicum in suitable host body, the experiment with yellow
