Quick facts
Horizontal gene transfer is sideways inheritance: DNA moves between contemporaries instead of only from parent to offspring.
That is why resistance genes can jump species in hospitals and farms. The public story is traffic, not a construction kit.
Transformation, conjugation and transduction are names for different vehicles. None of them is written here as a protocol.

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.
