Percentage of survived amoebae from cyst transformation to amoeboid form after 24 hours of incubation in PYG medium at 30 °C. 100 μM strontium chloride preserved the ability of amoeboid transformation as the survival reached 85.78%; similarly 100 μM PF-03716556 resulted in viability of 78.15%. 100 μM cariporide treatment resulted in 71.13% viable converted trophozoites. On the other spectrum of viability, treatment with 100 μM 3′,4′-dichlorobenzamil hydrochloride completely inhibited the excystation process. The use of 100 μM lanthanum oxide and stevioside hydrate resulted in a partial inhibition of the excystation, with respective cell viability of 22.75% and 29.41%, respectively. Asterisks represent significance of differences in comparisons with controls (*P < 0.05, **P < 0.01). The figure is representative of three experiments
