Comparison of ability of LPFShigella and LPFLF82 bacteria to interact with murine PPs.
(A) Quantification of murine PP-associated bacteria for AIEC strains LF82 and LF110 and corresponding ΔlpfA mutants. See the legend to Figure 1C. Each value is the mean ± SEM of at least 5 separate experiments. (B) Visualization of bacteria interacting with murine isolated PPs. Scale bars: 100 μm for HES staining and 50 μm for confocal analysis. Images in the right column correspond to the boxed regions in the left row. See the legend to Figure 1D. *P < 0.05, **P < 0.01.
