利用经照射致弱的血吸虫幼虫获得免疫力来作为血吸虫病的一项潜在的控制方法,已受到越来越多的关注;特别在绵羊、牛及狗等大动物的免疫实验方面有很快的进展。注射体外培育的、照射致弱的血吸虫童虫以及最近用冰冻保存的、照射致弱的童虫均诱发了免疫性。 As a potential control of schistosomiasis by immunizing weak larvae of Schistosoma japonicum with larvae, it has received more and more attention; in particular, immunization experiments with large animals such as sheep, cattle and dogs have been rapid progress. Injecting in vitro cultured, weakly irradiated schistosomula and, more recently, cryopreserved, poorly irradiated, juvenile worms induce immunity.
