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.
Biology here is spatial. A shaken flask is a different world from a coated catheter lumen.
Drug tolerance can come from slow growth and matrix, which is not the same as a heritable resistance gene.
Parts
Microcolony
Early piles of cells start making matrix and talking by diffusion.
Channels
Some mature films have water channels that move nutrients — cities, not solid bricks.
Slow members
Dormant-like cells can survive a chemical pulse and restart later.
Signals
Quorum-sensing molecules coordinate group jobs at high density, in outline only here.
Shed particles
Detached clumps can travel in blood or water and start a new film.
Life cycle
1Attach
A few cells stick to a conditioned surface.
2Build
Division plus EPS turns specks into a microcolony.
3Mature city
Gradients and mixed jobs appear; some cells slow down.
4Disperse
Pieces leave. Downstream surfaces or tissues may be seeded.
No culture protocol is included.

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.
