The behavior of Biomphalaria tenagophila amoebocytes was studied in infections produced by Schistosoma mansoni and other Digenea. The resistance to superinfection was also verified in mixed infections. Data on amoebocyte phagocytic activity, on the number of amoebocytes in hemolymph, and on amoebocyte tissue reactions were obtained and electrophoretic and immunodiffusion examinations of the hemolymph were carried out. It was concluded that the snails infected with Digenea show resistance to superinfection with S. mansoni. Apparently sporocysts are not destroyed by the action of amoebocytes. An increase in amoebocyte phagocytic activity was discovered in infected snails. Immunoelectrophoresis shows quantitative and qualitative differences in the hemolymph of the infected snails.
研究了曼氏血吸虫和其他复殖吸虫感染时，小土蜗血细胞的行为。还在混合感染中验证了对再次感染的抵抗力。获得了关于血细胞吞噬活性、血淋巴中血细胞数量以及血细胞组织反应的数据，并对血淋巴进行了电泳和免疫扩散检查。得出的结论是，感染复殖吸虫的蜗牛对曼氏血吸虫的再次感染具有抵抗力。显然，包蚴不会被血细胞的作用所破坏。在受感染的蜗牛中发现血细胞吞噬活性增加。免疫电泳显示受感染蜗牛血淋巴在数量和质量上存在差异。
