Invasion of Lm EGD-e (WT), EGD-e ΔagrD (ΔagrD), or EGD-e ΔagrD::pIMK2agrD (Comp) into Caco-2 cells. Bacteria were grown either in the absence (black bars) or presence of 5 μM peptide R5T0. Values are colony forming units per well (cfu/well) and are mean ± standard deviation of three independent experiments. Statistical analysis was performed by comparing all strains for a given condition (with or without peptide) by ANOVA. Bonferroni post tests were used to adjust p values for multiple comparisons.
