Quantification of the expression of the virulence-associated genes of C. jejuni. Primary chicken embryo intestinal cells (CEICs) were inoculated with C. jejuni chicken strain SC11 and human strain HM5040 at a MOI of 100:1, total RNA was isolated, and the expression of ciaB, dnaJ and racR of C. jejuni in internalized/adhered (IA) and suspended (SU) bacteria were measured at various time points post inoculation (p.i.) (see Methods). Mock inoculation was used as control. Data are representative of those from three independent experiments relative to mock inoculations (average ± SD).
