Fluorescence microscopy analysis of F-actin in Caco-2 cell monolayers incubated for 3 h with EPEC in the absence or presence of COF-SN or OMVs from the indicated bacterial strains. F-actin was stained with TRITC-labelled phalloidin (red) and analysis was performed as described for Fig. 4. Images shown are representative of three independent biological experiments. Scale bar: 10 μm
