C. jejuni M1 colonisation in line 6₁ and line N birds. Birds were orally inoculated at 3 weeks of age with 10⁸ CFU of C. jejuni M1 and the number of C. jejuni M1 per gram of caecal content determined at 1 and 5 dpi. Shown are the log₁₀ CFU of C. jejuni per gram of caecal content from individual birds. N = 3 for each line at each time point. Crosshairs represent the mean count for each group. Significant differences were determined by Anova where * indicates significance at P < 0.01
