已有实验证明,自穿入宿主皮肤后1～4天内的血吸虫童虫即能吸附宿主的血型抗原,它有效地掩蔽了外来抗原的位点,防止特异性抗寄生虫抗体的结合,并提示宿主特异血型抗原与血吸虫病临床的关系。本文目的,在于探讨血吸虫病的流行情况及严重程度与血型系统及分泌抗原能力间的相关性。研究对象为非洲斯威士兰农村小学生(8～13岁),均未进行过血吸虫病治疗和采取
It has been experimentally demonstrated that Schistosoma japonicum, a member of the schistosomula, can adsorb the host’s blood group antigen within 1 to 4 days after it penetrates the skin of the host, effectively masking the site of the foreign antigen and preventing the binding of specific anti-parasitic antibodies and suggesting Relationship between host specific blood group antigen and schistosomiasis. The purpose of this paper is to explore the relationship between the prevalence and severity of schistosomiasis and the ability of the blood group system to secrete antigen. Study for rural Swaziland primary school students in Africa (8 to 13 years old), have not been treated and taken schistosomiasis
