Iraq and intestinal ailments?

One of the last things I saw before I left active duty was a study being performed by the gastroenterology clinic. Basically,please leave your poop at the front desk for our study sort of thing. They reported that there was all sorts of nasty bacteria that they didn't even know existed. Has more info been made available that anyone is aware of? In my tiny air cav troop, 3 of us have at least 5 separate required surgeries and they don't seem to think it is irregular. We were in the Sunni Triangle area, te Syrian brder, and Al Asad. Will there be a Gulf War II syndrome in 20 years?
