Four-month-old worm-free Merino lambs were dosed with 20 000 infective larvae of Trichostrongylus axei on Day 0 and again on Day +14. On Day +83 they were treated with mebendazole at 15 mg/kg. All lambs in this group and a further group of 11 worm-free Merino control lambs were challenged with 50 000 infective larvae of Haemonchus contortus dosed from Day +90-Day +92. At necropsy 27 and 28 days later there was no significant difference between the worm burdens of the 2 groups. T. axei must be present in the abomasum to protect sheep from challenge with H. contortus.
4月龄无蠕虫美利奴羔羊在第0天和第+14天分别接种20000条艾氏毛圆线虫感染性幼虫。在第+83天，它们接受了15mg/kg的甲苯咪唑治疗。该组所有羔羊以及另外11只无蠕虫美利奴对照羔羊从第+90天至第+92天接种50000条捻转血矛线虫感染性幼虫进行攻虫试验。在27天和28天后剖检时，两组的蠕虫负荷没有显著差异。皱胃中必须存在艾氏毛圆线虫才能保护绵羊免受捻转血矛线虫的攻虫感染。
