Myth
Bacteria have no way to share genes.
Reality
They have several named routes. That is why resistance can hop species.
Popular talk either ignores plasmids or treats every bacterium as a programmed weapon. Both miss ordinary traffic.
Correcting myths is not a lab class.
Myths vs evidence
Myth
HGT means scientists engineered the strain.
Reality
Most clinical plasmids are natural traffic under selection, not a signed lab product.
Myth
If I understand HGT I should try it at home.
Reality
Understanding is history and public health. Methods for moving genes are omitted here.
Myth
A species name guarantees the same genes.
Reality
Two E. coli cells can differ by whole cassettes of luggage.
Myth
Phages only kill bacteria, they never deliver genes.
Reality
Transduction is accidental packaging. It is one reason genes tour.
Myth
Stopping all gene talk prevents biothreats.
Reality
Silence does not stop plasmids in sewers. Surveillance and stewardship do more.
Conjugation, transduction and transformation are names for why resistance genes travel. This page stops at the names and the history.

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 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.
