Digenetic trematodes: multiplication of the intramolluscan stages in some species is potentially unlimited.
By carrying out chain-transplantations of intramolluscan stages of digeneans from infected to uninfected snails it has been demonstrated that a great number of generations of these stages can follow one another. In Echinostomatids the succession of redial generations potentially seems to be unlimited.
