Quick facts
In 1982–84 Barry Marshall and Robin Warren linked a spiral gastric bacterium to gastritis, overturning acid-only ulcer dogma.Marshall and Warren
They shared the 2005 Nobel Prize in Physiology or Medicine for the Helicobacter pylori and peptic-ulcer work.Nobel 2005
The organism makes urease that generates ammonia, a conceptual way to survive stomach acid.Urease shield
WHO's IARC classified H. pylori as a Group 1 carcinogen for gastric cancer in 1994.IARC 1994
South Korea historically had high seroprevalence that has declined with socioeconomic change and treatment programmes.Korea prevalence
Most peptic ulcers associate with H. pylori or with non-steroidal anti-inflammatory drugs — two different stories.Ulcers and NSAIDs
Helicobacter pylori is a spiral bacterium that lives in the stomach mucus and rewrote the ulcer textbook in the 1980s.
Marshall and Warren's Nobel in 2005 recognized that many ulcers are an infection. Korea's historically high prevalence makes the story local as well as global.

A stomach resident with a Nobel
English clinic talk now treats many ulcers as an infection story, not only stress. H. pylori is the named bacterium.
Nobel story
Marshall and Warren are the history hook in textbooks.

Frequently asked questions
Where should I start with Helicobacter pylori?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Helicobacter pylori?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Encounters before English norms look universal.
Are the scores a ranking of Helicobacter pylori?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Helicobacter pylori to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
Can I cite these scores externally?
Treat them as atlas orientation, not certificates or forecasts.
What should I check before acting?
Primary desks for Encounters: public-health desks and lab teaching frames.
