Figure 2From: Inhibition of Streptococcus pneumoniae adherence to human epithelial cells in vitro by the probiotic Lactobacillus rhamnosus GGEffect of LGG on pneumococcal adherence to epithelial cells. Pneumococcal adherence was determined when incubated with medium alone (Pnc), or with medium containing 100 U/ml heparin (Heparin), or ~5 x 106 CFU LGG (LGG low), or ~5 x 107 CFU LGG (LGG high) added one hour before (A), concurrently (B), or one hour after adding pneumococci (C). One-way ANOVA revealed significant differences in adherence levels (P < 0.05) for all isolates except PMP812 (serotype 5) in the post-addition assay. For each isolate, Bonferroni’s post-test was used to compare heparin, LGG low, and LGG high to Pnc: *, P < 0.001; #, P < 0.05. Data are mean + SD (n≥3).Back to article page
