Examination at necropsy of the abomasum and intestinal tract of 62 sheep (including both sexes) of Karnah breed, aged one to two years over a period of one year was conducted at Handwara, situated in the north-west of Kashmir Valley. The following species of nematodes were found: Haemonchus contortus, Trichostrongylus axei, Trichostrongylus colubriformis, Bunostomum trigonocephalum, Chabertia ovina, Nematodirus spathiger, Skrjabinema ovis and Trichuris ovis. Infections with Trichostrongylus axei and T. colubriformis were, respectively, 57.7 and 40.2% of the total of all nematodes recovered. Faecal examination of adult sheep of Karnah breed, aged two to four years, comprising mostly pregnant and lactating ewes, showed a rise in strongyle egg counts during the months of March and April, coinciding with the lambing season in the area. The lambs showed a rise in faecal strongyle egg output from May onwards. The counts reached their peak during the month of September. It is presumed that pastures contaminated by pregnant and lactating ewes during the spring season were responsible for the acquisition of heavy nematode infections by lambs in the area.
在克什米尔山谷西北部的汉德瓦拉，对62只年龄在1至2岁的卡尔纳品种绵羊（包括雌雄）的皱胃和肠道进行了为期一年的尸检。发现了以下线虫种类：捻转血矛线虫、奥氏毛圆线虫、蛇形毛圆线虫、三角头仰口线虫、绵羊夏伯特线虫、斯氏细颈线虫、绵羊斯克里亚宾线虫和绵羊鞭虫。奥氏毛圆线虫和蛇形毛圆线虫的感染率分别占所有回收线虫总数的57.7%和40.2%。对2至4岁的卡尔纳品种成年绵羊（主要是怀孕和哺乳的母羊）进行粪便检查发现，在3月和4月期间，圆线虫卵计数有所上升，这与该地区的产羔季节相吻合。羔羊从5月起粪便中圆线虫卵的排出量增加。计数在9月份达到峰值。据推测，春季怀孕和哺乳母羊污染的牧场是该地区羔羊感染大量线虫的原因。
