2005 - Professor Barry Marshall and Emeritus Professor Robin Warren

Professor Barry J Marshall with Professor Robin Warren showed that Helicobacter pylori is the main cause of stomach and duodenal ulcers. This discovery was the first step in developing more effective treatments for ulcers and in understanding the causative link between H. pylori and stomach cancer.

Thanks to the pioneering discovery by Professor Marshall and Dr Warren, peptic ulcer disease is no longer a chronic, frequently disabling condition, but a disease that can be cured by a short regimen of antibiotics and acid secretion inhibitors.
