Nobel prize for Physiology and medicine in 2005 (Peptic ulcers) :

Peptic ulcers :  Acidity related pain and bleeding in the stomach and duodenum two Australians made a discovery that a bacterium, Helicobacter pylori, was responsible for peptic ulcers.

Robin Warner (born 1937) a pathologist from Perth Australia saw these small curved bacteria in the lower part of the stomach in many patients and noticed that signs of inflammation were always present around these bacteria.

Berry Marshall (born 1951) became interested in Warren's findings and succeeded in cultivating the bacteria from these sources.

Marshall and Warren showed that patients could be cured of peptic ulcers only when the bacteria were killed off from the stomach by a short period of treatment with antibiotics.

For this achievement, Marshall and Warren received the Nobel prize for Physiology and medicine in 2005.
