We report the first evidence of natural infection of Lymnaea columella with Fasciola hepatica in Argentina. A
sample of 601 snails was collected in May 2003 in northeastern Corrientes, a province bounded on the north by
Paraguay, on the east by Brazil and on the southeast by Uruguay. Among 500 examined snails, 44 (8.8%) were
exclusively infected with F. hepatica. Parasite identification was based on morphological features of cercariae from
snails, and of eggs and adult flukes from Wistar rats. We discuss the events suggesting that an enzootic transmission
cycle of F. hepatica has been recently established in northeastern Corrientes.
