Phages infect people like flu.
They infect bacteria. Human viral diseases are a different chapter.
Bacteriophages — Viruses that infect bacteria — Earth's most abundant biological entities, and a concept-level idea in medicine.

Public-health education — not a care plan, prescription, or outbreak briefing.
It names everyday desks for Tree of microbes before English norms look universal.

Use related cards and best-of / quiz rails after the first three chapters.
How they live and Body & health carry mechanisms; skim Identity first.
Internet shops sometimes sell 'phage' as a cure-all. Biology is narrower: one phage, one kind of bacterium, often one strain.
Myths below are common queries. They are not a prescription and not a protocol.
They infect bacteria. Human viral diseases are a different chapter.
Host range is usually narrow. That is a safety feature and a logistical headache.
It is published, regulated unevenly, and limited by matching. Secrecy is the wrong plot.
This atlas forbids that how-to. Environmental samples can include pathogens you did not want.
They may share the load someday. Surgery, vaccines and stewardship will still exist.
You already host a virome. Random extra particles are not a diet plan.
If a claim says phages will replace every antibiotic next year, ask who matches the strain and who regulates the vial.
Single-celled prokaryotes with cell walls — the oldest widespread life form, and both partners and pathogens.
Familiarity 95Packets of DNA or RNA that are not cells — they replicate only inside living hosts.
Familiarity 96A eukaryotic kingdom of yeasts, moulds and mushrooms — chitin walls, external digestion, partners of plants.
Familiarity 80A prokaryotic domain that is not bacteria — methanogens, extremophiles and no known human pathogens.
Familiarity 35Motile unicellular eukaryotes — a teaching grade that includes pond ciliates and a minority of serious parasites.
