The authors also found that compared to uninfected ferrets, C. jejuni-infected ferrets had elevated levels of IL-10 and TNF-α, by 3-fold and 2-fold (p < 0.05), respectively, and populations of granulocytes and macrophages trafficked to and peaked in colonic tissue early in the infection course (day 3), followed by gradual resolution at day seven. The gene discussed is IL10; the disease is infection.
