IL10 and infection: Microbiota depleted IL-10−/− mice were perorally infected with 109 colony forming units (CFU) C. jejuni strain 81-176 on days 0 and 1 and subjected to either urolithin-A or placebo treatment via the drinking water as initiated on day 2 p.i. Our cultural analyses revealed that on days 2, 3 and 4 post infection (p.i.), fecal C. jejuni numbers were lower in the urolithin-A as compared to the placebo cohort (p < 0.01–0.001), whereas later-on, comparably high median pathogen loads of approximately 109 CFU per g fecal sample could be determined (not significant (n.s.); Supplementary Figure S1).
