That is why I posted a link instead of spelling it out!
The whole thin is an amazing story though. The Clinician that discovered that H. Pylori caused ulcers presented a paper in the late 1970's. He was laughed off of the stage and called a Quack by Linus Pauling among others. He could not get funding for human trials so infected himself and then cured himself.
....still the Medical community would not believe that Ulcers were mostly(like 95% or so) caused by H. Pylori. There is still a lot or resistance even though the AMA finally added it as the accepted cause and anti antibiotics as the standard treatment..In 2007! Good God that is nearly 30 years of Quackery by the medical profession! Seriously folks, almost all stomach ulcers are cured in two weeks and could have been for 30 years...
