- Barry Marshall and Robin Warren won the 2005 Nobel Prize in Physiology for discovering Helicobacter pylori's role in gastritis and peptic ulcers.
- Marshall's self-experiment in 1984 involved ingesting H. pylori, leading to gastritis, proving its pathogenicity in healthy individuals.
- H. pylori infection is widespread, especially in poor countries, and Marshall aims to control its global health impact.
- Treatment of H. pylori has drastically reduced peptic ulcers in Australia, saving $300 million annually, though gastric cancer risk remains.
- H. pylori transmission mainly occurs in early childhood, with low reinfection rates in adults in developed countries.
- Future research may link H. pylori to iron deficiency anemia, cardiovascular disease, and immune disorders, with potential for eradication programs.
