Hospederos intermediarios de Fasciola hepatica en el Perú.

The natural and experimental infection of Peruvian lymnaeid snails with larval stages of Fasciola hepatica was demonstrated. The index of natural and experimental infection was of 12% and 28% in Lymnaea columella and of 27% and 70% in Lymnaea viatrix, respectively. Lymnaea diaphana and Lymnaea cousini did not present natural infection and demonstrated not to be prone to experimental infection. [ABSTRACT FROM AUTHOR]
