The response of Awassi sheep and the local breed of Iraqi goats to primary infection with a prevalent trichostrongylid nematode, Haemonchus contortus, was compared by examining their worm burden and the pathogenic effects of the parasite on these hosts following experimental infection. The results showed that the goats had lower worm burdens and had suffered less severe clinical and haematological disturbances than the Awassi sheep. The worm counts in sheep were higher than in goats but the count of the mucosal phase of the larvae was higher in goats. These differences are possibly immunologic in origin though a genetic resistance may operate, primarily at the level of worm establishment. The pathophysiological changes are correlated with parasitological and clinical observations in the two host species.
通过检查实验感染后阿瓦西绵羊和伊拉克当地山羊品种对常见毛圆线虫捻转血矛线虫初次感染的蠕虫负荷以及寄生虫对这些宿主的致病作用，比较了它们的反应。结果表明，山羊的蠕虫负荷较低，临床和血液学紊乱程度也比阿瓦西绵羊轻。绵羊的蠕虫计数高于山羊，但山羊幼虫黏膜期的计数更高。这些差异可能源于免疫，尽管可能存在遗传抗性，主要在蠕虫定植水平起作用。病理生理变化与这两种宿主物种的寄生虫学和临床观察结果相关。
