title: Elemental changes during sexual maturation inSchistosoma mansoni.
abstract: Changes in the elemental composition ofSchistosoma mansoni in relation to age and sexual status are described, and studies on the structural localization of calcium in adult worms and the elemental composition of the tegument-subtegumental tissues are reviewed. Some preliminary results on the distribution of Ca(2+)-dependent ATPase activity in the tegument of worms from both mixed and single-sex infections are also presented.
