Examples of regeneration and developmental plasticity in adult schistosomes. (a) Schistosomes are able to at least partially regenerate their tegument following sub-lethal praziquantel treatment. (b) Maturation and pairing of male and female schistosomes requires an intact immune system. (c) Single-sex infection and unpairing of worms results in regression of reproductive organs in the female. This regression is reversible, with restoration of reproductive machinery upon pairing with a male worm.
