体液抗体在血吸虫病获得性免疫中的作用尚未确定。尽管有人认为循环抗体在猴的免疫中起主要作用,但在其他宿主并未肯定。不能将现用传统的血清方法测定同宿主的免疫状态联合起来。作者将童虫培养在正常及兔疫血清内18～66小时,观察虫体活动,或用双醋酸萤光素(1:1,000)染色法作萤光显微镜观察,或用依文思蓝排除染色法以测定死活。实验证明曼氏血吸虫童虫在大白鼠、兔、小白鼠及猴的免疫血清内,大部份被破
The role of humoral antibodies in acquired immunity in schistosomiasis has not been established. Although circulating antibodies are thought to play a major role in monkey immunity, others are not certain. The current traditional serum method can not be combined with the host’s immune status. The authors cultured Schistosoma japonicum in normal and sera of rabbits for 18-66 hours, observed the activity of parasites, observed the fluorescence microscopy with fluorescein acetate (1: 1,000), or excluded Evans blue To determine the live and death. Experiments show that Schistosoma mansoni Schistosoma japonicum in the immune serum of mice, rabbits, mice and monkeys, most of the broken
