Attachment
Cells stick to teeth, plastic or tissue with adhesins and then recruit neighbors.
Darker cells mean a higher score for this topic on that metric.

Quick answers
Where should I start with Biofilms?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Biofilms?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Change & defence before English norms look universal.
Are the scores a ranking of Biofilms?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Biofilms 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 architectural: attachment, matrix, oxygen and food gradients, and cells not all in the same hurry.
Tests on floating cells underestimate what a film can shrug off. That gap is why some infections linger.
Traits
Matrix
EPS is the mortar. It holds water and can slow diffusion of some chemicals.
Gradients
Oxygen and nutrients fall with depth, so inner cells may grow slowly.
Mixed species
Oral and environmental films are rarely a monoculture. Cross-feeding is common.
Dispersal
Chunks or single cells can leave to seed a new surface in plumbing or wards.
Not a lab recipe
How to grow a film on purpose is omitted. The public story is why some infections persist.
A biofilm is a lifestyle, not a species name.

Mutation and variants
Populations of genomes, not cartoon villains — RNA viruses copy sloppily, and public-health names track clusters that spread.
Familiarity 92Antibiotic resistance
A shared drug budget under selection in hospitals, farms and wastewater — stewardship, not a lab manual.
Familiarity 85Vaccines and immunity
Antibodies, memory cells and community arithmetic — conceptual, not a prescription and not an anti-vaccine tract.
Familiarity 94Hygiene and balance
Clean water saves lives; missing old microbial partners is a separate, still-debated immune story.
Familiarity 70Horizontal gene transfer
Sideways DNA traffic — conjugation, transduction, transformation as names and history, not protocols.
