Effect of rice bran extract on Salmonella entry and intracellular replication in MSIE cells. MSIE cells pre-incubated with rice bran extract (RBE) at doses of 0, 0.5, 1.0 and 2.0 mg/ml for 24 hours, followed by the co-incubation of the RBE with Salmonella showed significant inhibition of Salmonella entry (A). RBE was tested for effects on intracellular Salmonella replication inside MSIE cells for 24 hours (co-incubated with RBE) (B). Bacteria are shown as mean ± standard deviation of mean log₁₀ CFU per mL of cell lysate (n = 3). Significance was determined using a nonparametric (Kruskal Wallis) ANOVA, followed by Dunn’s multiple means comparison. Statistical differences denoted by * (P < 0.05) and ** (P < 0.01).
