Last week, the Nobel Prize in medicine was awarded to Australia's Barry Marshall and his collaborator Robin Warren. They discovered in the early 1980s that gastritis or peptic ulcer disease were most often caused by the bacterium Helicobacter pylori. Interestingly, when they announced their preliminary findings in Brussels in 1983 that a bacterium could be the cause of ulcers and gastritis and that antibiotics might be effective in their treatment, many in the audience dismissed their findings as being preposterous. It was "well-known" then that gastritis and peptic ulcers were "life-style diseases" brought on by stress, spicy diets, and drinking too much.
