Barry J. Marshall, J. Robin Warren Helicobacter pylori and Its role In gastritis and peptic ulcer disease... 

Until recently, it was believed that excess stomach acid caused stomach ulcers. It has now been proved that the cause is instead a bacterial infection and that ulcers can be successfully treated with antibiotics. The 2005 Nobel Prize in Physiology or Medicine was awarded to Barry J. Marshall and J. Robin Warren for their discovery of the role of Helicobacter pylori in gastritis and peptic ulcer disease. 

In 2005, J. Robin Warren and Barry J. Marshall shared the Nobel Prize in Medicine for discovery of the bacterium Helicobacter pylori, and for establishing experimental proof that it plays a major role in gastritis and peptic ulcer disease. The story began when Warren, a pathologist, noticed that bacilli were associated with the tissues taken from patients suffering from ulcers. Look up the history of this case and describe Warren s first hypothesis. What sorts of evidence did it take to create a credible theory based on it ... 

In 1982, the Australian scientists Barry Marshall and Robin Warren (Marshall 2002) discovered the bacterium helicobacler pylori in the stomachs of ulcer patients. For over 10 years, with strong scientific evidence behind them, they attempted to convince physicians that ulcers were a result of bacterial infection. They were told this was absurd. Bacteria could not live in the strong acidity of the stomach. In the course of their work, they found that previous studies had also discovered bacteria in the stomachs of ulcer patients. However, because it was generally accepted that the environment was too acidic for bacteria to survive, these previous studies assumed that the bacteria had been the result of some contamination of their samples. They constructed a perception of reality based on their beliefs.
