Myth
The patient becomes immune to antibiotics.
Reality
The microbe changes or is replaced by a resistant strain. The person's immune system is a different story.
Advertising and fear both distort the story. The accurate picture is selection plus gene traffic plus policy.
Myths below are search-common. They are not a treatment algorithm.
Myths vs evidence
Myth
If one pill helped, leftover pills are a stash.
Reality
Wrong drug, wrong bug, wrong duration. Sharing leftovers is how stewardship fails at home.
Myth
Resistance is only a hospital problem.
Reality
Farms, wastewater and community clinics are connected. MRSA and resistant gonorrhea also live outside wards.
Myth
Stronger cleaning chemicals prevent resistance.
Reality
Some biocides add their own selection. Targeted hygiene beats soaking an entire life in residual agents.
Myth
Scientists should publish how to make superbugs so we understand them.
Reality
Understanding is epidemiology, stewardship and basic mechanisms — not a construction manual.
Myth
Stopping all antibiotics tomorrow fixes it.
Reality
People with sepsis still need drugs. The aim is fewer unneeded courses, not a ban on medicine.
Stewardship is a shared budget: use the right drug when lives need it, and stop treating leftover pills as a home pharmacy.

Mutation and variants
Populations of genomes, not cartoon villains — RNA viruses copy sloppily, and public-health names track clusters that spread.
Familiarity 92Vaccines and immunity
Antibodies, memory cells and community arithmetic — conceptual, not a prescription and not an anti-vaccine tract.
Familiarity 94Biofilms
Surface cities of microbes — plaque and catheters explain persistence, without a grow-your-own kit.
Familiarity 38Hygiene 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.
