Low <i>C. jejuni</i> inoculum induced colitis in IL-10^−/− mice.

<p>IL-10^−/− mice were infected with different amounts of <i>C. jejuni</i> (10², 10⁴, and 10⁶ cfu/mouse) for 14 days. (A) The degree of intestinal inflammation was determined by histological analysis of colonic sections as described. (B) Representative section of the colon of IL-10^−/− mice infected with 10² bacteria. n = 5 per group, magnification 100x.
