在一项为期三年的计划中分析了自然条件下肝镰刀菌的传播。使用的变量是间接血凝（IHA）技术、示踪羔羊体内的蠕虫建立情况以及蒺藜螺的种群动态、感染率和脱落模式。得出的结论是，吸虫卵、受感染的蜗牛和牧草上的囊蚴可以在荷兰过冬。囊蚴的可用性与放牧期间的降雨量呈正相关。越冬的发育卵的作用很重要，因为这会导致牛群较早感染。使用血清学诊断方法 IHA 对于早期检测肝镰刀菌感染非常重要。在浮子上使用玻璃纸是确定蒺藜尾蚴脱落模式的有用方法。结论是，玻璃纸浮子上囊蚴的收集、蒺藜吸虫的发明及其感染水平是预测肝吸虫感染的有用工具。
Transmission of F.hepatica under natural conditions was analysed in a three year programme. The variables used were the indirect haemagglutination (IHA) technique, worm establishment in tracer lambs and the population dynamics, infection rate and shedding pattern of Lymnaea truncatula.It is concluded that fluke eggs, infected snails and metacercariae on herbage can survive the winter in the Netherlands. Metacercarial availability was positively correlated to the amount of rainfall in the grazing period. The role of developed eggs that survive the winter is important, because this results in earlier infections in the herd.The use of the serological diagnosis method IHA is important to detect F. hepatica infection in an early stage. Use of cellophane paper on floats is a useful method for determining the shedding pattern of cercariae from L. truncatula. It is concluded that collection of metacercariae on cellophane floats, inventarization of L. truncatula and its infection level are useful tools for the prediction of liverfluke infections.
