In Kashmir, 85.1% of cattle, 51.3% of sheep and 14.8% of goats were found infected with Fasciola spp. The prevalence rate varied from 66.6 to 100.0%, 25.0 to 100% and nil to 66.0% in cattle, sheep and goats respectively in different months of the year. Fasciola gigantica was the predominant species in all animal species but sheep harboured both F. gigantica and F. hepatica. The prevalence of F. hepatica infection in sheep happens to be the first report from India. Lymnaea auricularia sensu stricto supported the development of F. gigantica under laboratory conditions. The incubation temperature affected the shedding of the cercariae. Snails maintained at 25-27 degrees C started cercarial shedding as early as day 20 post-infection (PI), whereas those maintained at 10-12 degrees C commenced it from day 64 PI. One out of three experimentally infected guinea pigs aged 1 month revealed adult flukes in the liver at necropsy on day 52 PI.
在克什米尔地区,发现85.1%的牛、51.3%的绵羊和14.8%的山羊感染了片形吸虫属。在一年中的不同月份,牛、绵羊和山羊的感染率分别在66.6%至100.0%、25.0%至100%和0至66.0%之间变化。巨片形吸虫是所有动物物种中的主要种类,但绵羊体内同时存在巨片形吸虫和肝片形吸虫。绵羊感染肝片形吸虫的情况是印度的首次报道。狭义耳萝卜螺在实验室条件下支持巨片形吸虫的发育。孵化温度影响尾蚴的逸出。维持在25 - 27摄氏度的蜗牛在感染后第20天就开始逸出尾蚴,而维持在10 - 12摄氏度的蜗牛则从感染后第64天开始。三只1月龄经实验感染的豚鼠中有一只在感染后第52天尸检时在肝脏中发现了成虫吸虫。
