title: Hatching of Schistosoma mansoni eggs is a Ca2+/calmodulin-dependent process.
abstract: The effect of calcium channel blockers (diltiazem and verapamil) and a calmodulin antagonist (W-7) on the hatching of Schistosoma mansoni eggs in fresh water was studied. The hatching of the eggs was inhibited by diltiazem and W-7 in a dose-dependent fashion and only slightly by verapamil. The present study indicates that the hatching of S. mansoni eggs is a Ca2+/calmodulin-dependent process.
