These epidemiological studies concern 187 cases of human fasciolasis which occurred in the region of Limousin, France on a period of 24 years. Four species of plants have been eaten: Nasturtium officinale, Roripa silvestris, Taraxacum gr. officinale, Valerianella olitoria. These plants have been eaten during all months of the year, but with higher numbers in July-August and from November to February. The cases of human fasciolasis almost take place on all years, but their numbers are high in years showing a very important infestation of cattle by Fasciola hepatica. In 2/3 of cases, the plants come from stations situated out of cattle pastures. The water-cress almost comes from natural stations or from familial plantations. Five species of snails have been observed in these stations: Lymnaea glabra, L. palustris, L. peregra, L. stagnalis, L. truncatula. The young snails of these species experimentally have been observed. The significance of these results is discussed.
这些流行病学研究涉及法国利穆赞地区24年间发生的187例人体肝片吸虫病病例。人们食用了四种植物：水田芥、沼生蔊菜、药用蒲公英、苣荬菜。这些植物全年都有人食用，但7 - 8月以及11月至次年2月食用量较多。人体肝片吸虫病病例几乎每年都有发生，但在肝片吸虫对牛感染非常严重的年份，病例数较多。在三分之二的病例中，这些植物来自远离牧场的地方。水田芥几乎都来自天然产地或家庭种植地。在这些产地观察到了五种蜗牛：光滑椎实螺、沼泽椎实螺、奇异椎实螺、静水椎实螺、截形椎实螺。还观察到了这些种类的幼螺。文中讨论了这些结果的意义。
