FIGURE 3.

Adhesion and Invasion of C. jejuni into HT-29 and 8E11 cells. HT-29 and 8E11 cells were infected with C. jejuni for 6 h before isolation and quantification of adherent and invasive C. jejuni. (A) Adhesion of C. jejuni strains to HT-29 and 8E11 cells. (B) Invasion of C. jejuni into HT-29 and 8E11 cells. (C,D) Treatment of HT-29 and 8E11 cells with signaling inhibitors for 30 min prior to invasion assays. Each dot represents three biological replicates in one strain. Results are also expressed as mean ± SD of all strains measured. Differences were considered significant if p ≤ 0.05.
