Amoebicidal effect of alexidine against A. castellanii, A. polyphaga, and A. rhysodes trophozoites. Trophozoites (1 × 106/mL) in the growth phase were incubated in peptone-yeast extract-glucose (PYG) medium containing 10 μg/mL and 20 μg/mL of alexidine for 24 hr. Trophozoites were then counted by hemocytometer. The control cultures were trophozoites incubated for 24 hr in PYG medium without alexidine. After 24 hr of incubation, the numbers of trophozoites were counted with hemocytometer. *Significantly different from untreated controls (P<0.05).
