Figure 3. Effects of enteropathogenic Escherichia coli (EPEC) strain E2348/69, EscF-complemented (ΔescF/escF), and type III secretion system (T3SS)-deletion mutant (ΔescF) infection on migration of IEC-6 cells A. Data are reported as mean±SE of three independent experiments (n=7). **P<0.01 and ****P<0.001 vs uninfected control; εεεP<0.001 vs ΔescF EPEC strain (ANOVA followed by Bonferroni's post-test). B, Intestinal cell migration after 6 h. The red line represents the initial cut and each square has an area of 0.1 mm2. Magnification 10×, bar: 200 μm.
