Figure 5From: Newer insights into the mechanism of action of Psidium guajava L. leaves in infectious diarrhoea Effect on invasion of S. flexneri to the HEp-2 cells in the pre-incubation and the competitive protocols with a) the decoction of P. guajava ; b) quercetin. C: Control, bacterial invasion to HEp-2 cells in medium alone; L1: Bacterial invasion to HEp-2 cells in medium with 2.5 mg/ml lactulose. Values represent mean ± standard error (n = 3) of percentage invasion relative to control (100%); * P < 0.05.Back to article page
