(A) Micrographs of colon sections from rabbits inoculated with WT EHEC, ΔΔstx EHEC, or PBS (mock) stained with a probe to rabbit CXCL11 mRNA (red) and DAPI (blue). Scale bar is 500 μM. (B) Percentage of tissue section with CXCL11 signal from individual colons. Distributions compared using Mann-Whitney U test, p<0.01 (**), n.s. indicates not significant. (C) Mean fluorescent intensity (MFI) from individual colons plotted with mean. Distributions compared using Mann-Whitney U test, p<0.01 (**), n.s. indicates not significant. (D) Percent CXCL11 signal within E-cadherin positive cells. Distributions compared using the Mann-Whitney U test, p<0.05 (*). (E) Sections stained with a probe to rabbit CXCL11 mRNA (red), DAPI (blue), and anti-E-cadherin antibody (white). Scale bar is 500 μM. Example immune cell (IC) and epithelial cell (EC) is indicated.
