Merino breed sheep eight months old at the beginning of the experiment and carriers of hemaglobin A were used. They were infected one or more times with H. contortus larvae and then challenged with 500 or 5000 larvae L3. Self-cure was reproduced and animals were found immune after infectation. Self-cure was more evident in females than in males and immunity was also better and appeared earlier in females than in males.
实验开始时使用了8个月大的美利奴品种绵羊，它们是血红蛋白A的携带者。它们被捻转血矛线虫幼虫感染一次或多次，然后用500或5000条L3期幼虫进行攻虫。重现了自愈现象，并且在感染后发现动物具有免疫力。自愈现象在雌性中比在雄性中更明显，并且雌性的免疫力也更好且比雄性出现得更早。
