This is a timeline of the events relating to the discovery that peptic ulcer disease and some cancers are caused by H. pylori. In 2005, Barry Marshall and Robin Warren were awarded the Nobel Prize in Physiology or Medicine for their discovery that peptic ulcer disease (PUD) was primarily caused by Helicobacter pylori , a bacterium with affinity ...
Peptic ulcer disease is when the inner part of the stomach's gastric mucosa (lining of the stomach), the first part of the small intestine, or sometimes the lower esophagus, gets damaged. An ulcer in the stomach is called a gastric ulcer , while one in the first part of the intestines is a duodenal ulcer . [ 1 ]

The Centers for Disease Control and Prevention says peptic ulcer disease affects about 6 million Americans every year. The sores are reportedly caused by an overproduction of gastric acid.
The ulcer is known initially as a peptic ulcer before the ulcer burns through the full thickness of the stomach or duodenal wall. A diagnosis is made by taking an erect abdominal/chest X-ray (seeking air under the diaphragm). This is in fact one of the very few occasions in modern times where surgery is undertaken to treat an ulcer. [3]
At the University of Western Australia,Warren along with his colleague Barry J. Marshall, proved that the bacterium is the infectious cause of stomach ulcers. [3] Warren helped develop a convenient diagnostic test (14 C-urea breath-test) for detecting H. pylori in ulcer patients. [4] In 2005, Warren and Marshall were awarded the Nobel Prize in ...
In 1982, they performed the initial culture of H. pylori and developed their hypothesis on the bacterial cause of peptic ulcers and gastric cancer. [9] It has been claimed that the H. pylori theory was ridiculed by established scientists and doctors, who did not believe that any bacteria could live in the acidic environment of the stomach.
