IL10 and colitis: In this study, we found that chicken-transmitted C. jejuni (passage 1, Cj-P1) induced more severe intestinal inflammation in Il10−/− mice compared to the non-transmitted bacterium (passage 0, Cj-P0), while Cj-P1-DCA-Anaero induced less colitis, bacterial invasion, and inflammatory gene expression in Il10−/− mice compared to Cj-P1.
