Figure 2: Effect of the decoction of C. rotundus on bacterial colonization to HEp-2 cells: (a) Adherence of EPEC strain B170; (b) Invasion of EIEC strain E134; (c) Invasion of S. flexneri (C: Control, bacterial adherence/invasion to HEp-2 cells in medium alone; L1: adherence/invasion to HEp-2 cells in medium with 2.5 mg/mL lactulose; L2: adherence to HEp-2 cells in medium with 15 mg/mL lactulose in the competitive protocol). Values represent mean ± standard error (n = 3) of percentage adherence/invasion relative to respective control (100%); *P < 0.05
