Quick answers
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.
Identity is a microaerophilic Gram-negative helix with flagella and a urease habit, living under mucus rather than in acid juice itself.
Most infections are silent for years. A subset become ulcers; a smaller subset sit on the gastric-cancer pathway.
Traits
Urease
Ammonia from urea is the textbook shield against gastric acid.
CagA talk
Some strains inject CagA, a protein discussed in cancer epidemiology — a marker, not a DIY target.
Childhood acquire
Infection is often a family story of crowding and sanitation, not a restaurant spice.
Nobel ulcer
The 2005 prize fixed the infection idea in public memory.
Not all gastritis
Alcohol, NSAIDs and autoimmunity also inflame stomachs. Tests distinguish.
Korea's falling seroprevalence is a public-health curve, not a personal clearance certificate.

Usually a gut resident; a minority of STEC pathotypes drive foodborne headlines.
Familiarity 82Staphylococcus aureus
A common skin neighbor and a resistance story called MRSA — not scare porn.
Familiarity 78Norovirus
A very-low-dose gut virus of schools and ships — soap and bleach surfaces, not alcohol-gel faith.
