The response of Awassi sheep and a local breed of goats to H. contortus, the prevalent ovine and caprine strongyloid species in Iraq, was studied. A dose of 500 H. contortus (sheep origin) larvae kg-1 body wt. induced clinical and pathological changes of haemonchosis. Although the percentage recovery of worms was higher in sheep, the pathological (gross and microscopic) changes were more marked in infected goats. The extensive abomasal changes noted in goats were, in general, accompanied by a higher density or larvae in the gastric wall; the pathology did not necessarily depend upon parasite count alone and a definite relationship could not be established. The tissue changes in the goats are possibly of immunological origin, although a genetic resistance may operate, primarily at the level of worm establishment.
研究了阿瓦西绵羊和当地一种山羊品种对捻转血矛线虫（伊拉克流行的绵羊和山羊类圆线虫物种）的反应。每千克体重500条捻转血矛线虫（源自绵羊）幼虫的剂量引发了血矛线虫病的临床和病理变化。尽管绵羊体内蠕虫的回收率更高，但感染山羊的病理（大体和微观）变化更为明显。山羊体内广泛的皱胃变化通常伴随着胃壁中更高密度的幼虫；病理学变化不一定仅取决于寄生虫数量，且无法建立明确的关系。山羊的组织变化可能源于免疫，尽管可能存在遗传抗性，主要作用于蠕虫定植水平。
