摘　　要：钉螺是血吸虫的唯一中间宿主,也是血吸虫病流行的重要环节,其在血吸虫病传播中发挥重要作用。本文从毛蚴入侵钉螺、胞蚴的发育、尾蚴的成熟与逸出和血吸虫寄生对钉螺的影响4个方面对钉螺与血吸虫的共生机制予以综述,旨在为揭示钉螺与血吸虫的共生关系提供文献数据。但是,血吸虫与钉螺的寄生关系较为复杂,二者共生的机制尚未完全阐明,有待更进一步的探讨。As the only intermediate host of Schistosorna japonicum, Oncomelania hupensis is an important link of schis tosomiasis. It plays an important role in the transmission of schistosomiasis. This article mainly demonstrates the following as pects： the invasion of schistosome miracidium into O. hupensis, the growth of sporocyst, and the mature and escape of cercari ae, which would provide laboratory data from literatures for revealing the symbiotic relationship between O. hupensis and S japonicum. However, the symbiotic relationship between O. hupensis and S. japonicurn is too complex to description com pletely. Therefore, the symbiotic relationship will be the focus of future research.
