"Lymnaea meridensis" is probably susceptible to "Fasciola hepatica" infection. "Lymnaea tomentosa" is an intermediate host of "Fasciola hepatica". It is used to treat "Anoplocephala perfoliata" (tapeworms) in horses and "Fasciola hepatica" (liver flukes). Bidloo contributed to discovery of the life cycle of the liver fluke "Fasciola hepatica". "Fasciola hepatica" occurs in the liver of a definitive host and its lifecycle is indirect.
