Serum taken from mice 12-15 weeks after a primary infection of Schistosoma mansoni transfers to normal recipients a partial resistance to subsequent schistosome challenge. The transfer of immunity is evident not only in the reduced recovery of mature parasites from the liver, but also in the diminished numbers of invading schistosomula recovered of resistance equivalent on average to 47% of that found in actively immunized animals, the results suggest that humoral factors play a major role in the effector mechanism of schistosome immunity.
在曼氏血吸虫初次感染12 - 15周后从小鼠采集的血清，可将对后续血吸虫攻击的部分抗性传递给正常受体。免疫传递不仅表现为从肝脏中回收的成熟寄生虫数量减少，还表现为回收的入侵血吸虫幼虫数量减少，平均抗性相当于主动免疫动物的47%。结果表明，体液因子在血吸虫免疫的效应机制中起主要作用。
