Clinical course following PACAP treatment of C. jejuni infected secondary abiotic IL-10^−/− mice. Mice were orally infected with C. jejuni strain 81–176 on day (d) 0 and d1 and subjected to intraperitoneal treatment, with either synthetic PACAP or vehicle (mock) from d2 until d5 post-infection. The clinical signs were quantitated daily according to defined clinical scores. Naive mice were used as negative controls. Box plots indicate the 75th and 25th percentiles of the median (black bar within boxes). The total range, the significance levels (p values calculated by the one-way ANOVA test followed by the Tukey post-correction test for multiple comparisons) and the total numbers of mice under investigation (in parentheses) are indicated. Results pooled from four independent experiments are shown.
