Effect of ionophores on in vitro excystment of Paragonimus ohirai metacercariae.
Ca2+ ionophores (A23187 and ionomycin) induced in vitro excystment of Paragonimus ohirai metacercariae, whereas Na+ ionophore (monensin) and K+ ionophores (nigericin and valinomycin) did not. The effect of A23187 on in vitro excystment was dependent on the concentration of the ionophore. A high concentration of 1 microM or more induced rapid excystment, but resulted in the death of metacercarial juveniles. The appropriate concentration of 0.2 microM induced in vitro excystment by 5 h after incubation with little or no damage to the juveniles.[1]References
