Parasites For Autoimmune Problems

Has anyone used parasites or bacteria to treat autoimmune problems? The research discussed in this article is very interesting:

It seems that parasites and bacteria can actually kind of "coach" your immune system to calm down. And since we don't have enough exposure to them in our super clean world, we may be having more autoimmunity problems.

I'd be curious to hear if anyone's tried this and what's happened for them?
