Swine were hyperimmunized to Ascaris suum by giving multiple oral inoculations of embryonated eggs. Sera and lymphocyte lysate from these pigs were administered parenterally to 4-week-old pigs. The latter animals were no more resistant to larval migration than control pigs receiving sera or lymphocyte lysate from non-immunized pigs. Other pigs were infected with transmissible gastroenteritis (TGE) virus, allowed to recover and challenged with embryonated ascarid eggs. They likewise were no more resistant to ascarid larval migration than control pigs.
通过多次口服接种感染期蛔虫卵，使猪对猪蛔虫进行超免疫。将这些猪的血清和淋巴细胞裂解物经肠胃外途径给予4周龄的猪。与接受未免疫猪的血清或淋巴细胞裂解物的对照猪相比，后一组动物对幼虫移行的抵抗力并没有更强。其他猪感染了传染性胃肠炎（TGE）病毒，待恢复后再用感染期蛔虫卵进行攻毒。与对照猪相比，它们对蛔虫幼虫移行的抵抗力同样没有增强。
