H. pylori: why did a doctor drink germs? #shorts

Based on documented events • Minecraft reconstruction. History at the Turning Point.

In the early 1980s, stress and lifestyle were thought to be the main causes of stomach ulcers. In Perth, Australia, pathologist Robin Warren saw curved bacteria in stomach biopsies, and young doctor Barry Marshall joined him and managed to culture them. Many experts disbelieved the results, and Marshall’s attempts to infect piglets failed. So in 1984 (the paper was published in 1985; some accounts give 1985), after an endoscopy showed his own stomach lining was normal, he swallowed a broth of the cultured bacteria. Within days he became ill and his breath turned foul. Biopsies about ten days after he drank it showed gastritis (inflammation) and the bacteria, later named Helicobacter pylori. He then treated himself with antibiotics. His experiment showed the germ causes gastritis; it did not give him an ulcer. Later studies showed H. pylori causes most stomach and duodenal ulcers, which can now be cured with antibiotics and acid-reducing drugs. Marshall and Warren won the 2005 Nobel Prize in Physiology or Medicine. Do not try self-experiments.

Simplified Minecraft reconstruction, not to scale: the giant stomach is a diagram; green blocks stand for the bacteria and red blocks for inflammation; a green glass block stands for the culture. Not footage and not a simulation. The characters are generic Minecraft villagers, and no real person’s likeness is shown.
