Effect of pomegranate extract or metronidazole treatments on the number of G. lamblia cysts and trophozoites in stool and intestine respectively. Data are expressed as means with error bars representing SD (n = 8) and were analyzed using ANOVA. Asterisks (*) indicate a significant difference in the numbers of cysts or trophozoites in treated groups compared to the infected untreated group (p = 0.003 and 0.001 for cysts and trophozoites, respectively), and a significant difference between the metronidazole- and pomegranate-treated groups; p = 0.001.
