Although the bacterium occupies half the stomachs on earth, its role in our lives was never clear. Then, in 1982, to the astonishment of the medical world, two scientists, Barry Marshall and J. Robin Warren, discovered that H. pylori is the principal cause of gastritis and peptic ulcers; it has since been associated with an increased risk of stomach cancer as well. Until that discovery, for which the men shared a Nobel Prize, in 2005, stress, not an infection, was assumed to be the major cause of peptic ulcers.
