The development of the host-response in juvenileLymnaea palustris to invasion byFasciola hepatica

Laboratory studies indicate that miracidia ofFasciola hepatica can penetrate several species of lymnaeids in Europe, other than the natural hostLymnaea truncatula. However, the production of cercariae from infections in abnormal hosts is limited to a small percentage of juvenile snails infected before a species-specific age.
