Effect of dietary rice bran on fecal Lactobacillus spp. Lactobacillus spp. DNA (pg/μl) from fecal pellets of mice before Salmonella infection (day 0) and at day 6 (post infection) was determined using qPCR. Error bars indicate standard deviation of mean and * (P < 0.05), ** (P < 0.01) and *** (P < 0.001) denote significant differences in rice bran fed mice from controls (n = 5 mice/diet group). Significance was tested by repeated measures ANOVA and Tukey’s post hoc test.
