I'm 100% with person who submitted "Bovine Manure." I also grew up on a farm with my hands in the dirt being exposed to every germ in the book. I developed an auto immune disease at 14. So the theory is crap. The best information I have found is that the root trigger for this is eating gluten and genetic predisposition. I have a parent, grandparent and brother with other autoimmmune diseases but different from mine. So don't eat wheat, barley, rye and maybe oatmeal and after about 1-2 weeks you will see improvement. I already have. So there!
