title: [Infection of Lymnaea cubensis by Fasciola hepatica in a high altitude region in Venezuela].
abstract: Lymnaea cubensis is the vector in a region of distome infection in Trujillo State at more than 1000 m altitude where almost all bovines are infected. A quarter of the molluscs were infected with a mean number of 20 rediae per infected molluc each redia capable of producing 16 cercariae. Prevalence of infection increases with size of molluse and is highest in those 4 to 5 mm long. However, Lymnaea as small as 3 mm produce cercariae and molluscicide treatments should be begun as soon as forms of this size appear.
