Studies on the infectivity of Fasciola hepatica miracidia to Lymnaea truncatula. Attachment and penetration of miracidia into non-infected and infected snails

摘要: Fasciola hepatica miracidia labelled in vivo with radioselenium have been used studies on the capacity of to attach and penetrate tegument infected compared non-infected host snails (Lymnaea truncatula). The results show that penetration larvae into snail tissue is not influenced by an already existing infection, regardless its developmental stage.
