Invasion of primary chicken embryo intestinal cells (CEICs) by C. jejuni. Cells grown at equivalent levels (1.7 × 10⁵ cells/well) were inoculated at an MOI of 100:1 with either C. jejuni strain SC11 (chicken isolate) or HM5040 (human isolate). The number of internalized bacteria was assessed by the gentamycin protection assay at 1, 2, 3, 4 and 24 h post inoculation (p.i.). Data are representative of three independent experiments (average ± SD).
