Throughout a period of 13 months, the abomasa of 1024 sheep, living in a sahelian region, were examined for adult Haemonchus contortus and their inhibited L4 larvae. Of these 796 (78%) were found harbouring H. contortus, but with low worm burdens (geometric mean 37). Significant numbers of inhibited larvae appeared early in the dry season (November) and they represented 49% of the total in December. A similar proportion of inhibited larvae were present until April and after that their number declined abruptly. It was concluded that Haemonchus sp. survives the dry season as hypobiotic larvae as well as adults.
在13个月的时间里，对生活在萨赫勒地区的1024只绵羊的皱胃进行了检查，以查找成年捻转血矛线虫及其处于抑制状态的L4幼虫。其中，796只（78%）被发现感染了捻转血矛线虫，但虫负荷较低（几何平均数为37）。大量处于抑制状态的幼虫在旱季早期（11月）出现，到12月时占总数的49%。直到4月，处于抑制状态的幼虫比例都相似，之后其数量急剧下降。得出的结论是，捻转血矛线虫以休眠幼虫和成虫的形式度过旱季。
