We report the first finding of Lymnaea viatrix south of parallel 41 masculine S, in rural and urban areas from Argentina. Ninety snails were collected during year 2000, from a concrete pond at a Public Square in El Bolsón Village, Río Negro province, and 811 snails in November 1999, and during 2000 from waterbodies within a farm at Cholila locality, Chubut province. Fasciola hepatica infection was detected in 0.9% snails from the rural area. We discuss the potential risk of L. viatrix to public health in urban areas and its epidemiological importance in rural areas of the Andean Patagonian region.
我们报告了在南纬41°以南的阿根廷农村和城市地区首次发现维亚特螺蛳（Lymnaea viatrix）。2000年期间，从内格罗河省埃尔博尔松村一个公共广场的混凝土池塘中采集了90只螺蛳，1999年11月以及2000年期间，从丘布特省乔利拉地区一个农场的水体中采集了811只螺蛳。在农村地区采集的螺蛳中，肝片吸虫（Fasciola hepatica）感染率为0.9%。我们讨论了维亚特螺蛳对城市地区公共卫生的潜在风险及其在安第斯巴塔哥尼亚地区农村的流行病学重要性。
