I too believe that my IBD is caused by bacteria. I have over time, responded well to antibiotics including Xifaxan (got 16 months of remission) and more recently, Cipro. Unfortunately, I have now developed tendonitis which can happen with Cipro and had to go off of it. My symptoms are bad again. I know it is bacterial, I just wish scientists could uncover exactly what bacteria it is and how to combat it. I will check out your suggested websites.
