Australian pathologist and Nobel Laureate, Robin Warren, needs no introduction. He won the Nobel Prize in Medicine in 2005 for the discovery of the bacterium Helicobacter pylori and its role in the gastritis and peptic ulcer disease. Warren’s life took a major turn when he noticed an unexpected bacterial growth in the gastric biopsy of a patient. Determined to find out the cause of it, he ventured forth and began extensively studying the same along with Barry Marshall. It took the duo seven years to eventually establish the presence of bacterium Helicobacter pylori as the major cause for peptic ulcer. Interestingly, their finding and research was not accepted by the scientific society which rebuffed the fact that bacteria of any kind could survive in the acidic environment of the stomach. It was only later on that the global community accepted the duo’s finding and thus awarded them with the prestigious Nobel Prize.
