Production of nitric oxide (NO) by primary chicken embryo intestinal cells (CEICs). CEICs were inoculated with C. jejuni strain SC11 (chicken isolate) and HM5040 (human isolate) at an MOI of 100:1, and NO in supernatants were measured at 4 and 24 hours post inoculation (p.i.). LPS E. coli 055:B5 (5 μg/ml) and mock inoculation were used as controls. Data are representative of three independent experiments and are presented as net increases of NO, from which the NO of the mock inoculations has been subtracted (average ± SD).
