Cytopathic assay of <i>E. histolytica</i> trophozoites in different conditions following short period of <i>E. coli</i> exposure.

<p>The cytopathic behavior of <i>E. histolytica</i> trophozoites and <i>E. coli</i> in different combinations, including WT (wild type, no bacterial exposure) trophozoites (n = 7), enteropathogenic <i>E. coli</i> O55 only (n = 10), as well as trophozoites incubated with enteropathogenic <i>E. coli</i> O55 (n = 10), dead <i>E. coli</i> O55 (n = 7), and nonpathogenic <i>E. coli</i> K12 (n = 7), was assessed and compared based on their ability to destroy a monolayer of HeLa cells. Statistical analyses, one-way ANOVA with post-hoc pairwise comparisons. * <i>p </i>< 0.05, ** <i>P</i> < 0.01, *** <i>P</i> < 0.001, **** <i>P</i> < 0.0001.</p>
