血吸虫生活史复杂,从尾蚴侵入皮肤在人体内寄生开始,经历童虫、成虫、虫卵阶段。为了适应宿主的内环境得以生仔,虫体的超微结构随之发生相应变化,这些不断变化的结构给血吸虫免疫机制的研究增添了难度。血吸虫各期虫体既具有共同抗原,也具有各自特异性抗原,它们在血吸虫的免疫诊断、免疫病理或诱导宿主的保护性免疫方面均具有重要作用。血吸虫免疫机制复杂,相关知识尚不完全清楚。对于血吸虫超微结构的研究,不仅可揭示虫体发育的形态学变
Schistosoma life history is complex, invade the skin from the cercariae parasites in the human body began to experience schistosomiasis, adults, eggs stage. In order to adapt to the host’s internal environment to give birth to the ultrastructure of parasites corresponding changes occur, these changing structure of the immune mechanism of schistosomiasis to increase the difficulty. Schistosome stages have both common antigens and specific antigens, which play an important role in immune diagnosis, immunopathology and protective immunity of the host. Schistosoma immune mechanism is complex, the relevant knowledge is not yet fully understood. The study on the ultrastructure of schistosomiasis can not only reveal the morphological changes of the development of parasites
