The amoebicidal activity of AgNPs against trophozoites of Entamoeba histolytica. E. histolytica trophozoite’s viability exposed to different concentrations of AgNPs 27.8, 55.6, and 111.2 µM of metallic silver (3, 6, and 12 µg/mL) and metronidazole (7 µM; 0.82 µg/mL) is shown in the left panel (a). The right panel (b) shows the micrographs of trophozoites (A) untreated and exposed to (B) 27.8 µM (3 µg/mL); (C) 55.6 µM (6 µg/mL), and (D) 111.2 µM (12 µg/mL) of metallic silver contained in AgNPs. The * represents a significant difference (p ≤ 0.05) compared with the negative control.
