The role of enterobacterial flora in the onset and progression of inflammatory bowel diseases is a topic of considerable interest. Here, we assessed the association among enterobacterial flora, dietary factors, and ulcerative colitis (UC) progression. Forty-six patients with UC who were diagnosed as being in remission were enrolled. We collected each patient’s stool sample one or two days before diagnostic colonoscopy. After colonoscopy, we observed the patients for one year and then retrospectively divided them into two groups: remission (n = 39) and relapse (n = 7) groups, depending on whether the relapse occurred during the follow-up period, and analyzed the relationship among patient characteristics, dietary factors, enterobacterial flora, and UC relapse. Overall, there were no significant differences in bacterial community populations between the remission and relapse groups, except that the order Lactobacillales was detected at a significantly higher rate in the relapse than in the remission group (100% vs 71.4%, p
