Possible involvement of calcium ions in the hatching of Schistosoma mansoni eggs in water.
The possibility of involvement of calcium ions in the hatching of Schistosoma mansoni eggs in water is described. The hatching of S. mansoni eggs under low osmotic pressure was partially inhibited by EGTA (5 mM), lanthanum chloride (1-5 mM), and ruthenium red (0.1-1 mM). The reagents used in these experiments were not toxic to the eggs however, because miracidia hatched normally when the reagents were removed.
