What is Helicobacter pylori?

Helicobacter pylori (or H. pylori) is a type of bacteria that can infect the stomach lining and cause various gastrointestinal problems, including gastritis, ulcers, and stomach cancer. It is one of the most common chronic infections in humans.

H. pylori causes inflammation of the stomach lining and weakens the natural protection against stomach acid, which may then cause an ulcer. If stomach acid is reduced with medications, an ulcer may heal, but it tends to come back once the medication is stopped. However, if H. pylori is treated successfully with antibiotics, an ulcer can be permanently cured. This means that the ulcer medication may no longer be needed.

In the spirit of Aussie entrepreneurship Professor Marshall famously ingested the H. pylori bacteria in an effort to prove that he had a cure. Who would have thought that single act of bravery could have resulted in a cure for stomach ulcers which has helped millions of people around the world.
