How does careful prescribing slow resistance?

Click to reveal answer

Restricting antibiotics to appropriate cases reduces selection pressure for resistant strains.

Key notes

Important points to keep in mind

Antibiotics target bacterial features; they do not affect viruses.

Specific antibiotics suit specific bacteria; testing guides the choice.

Resistance arises by mutation or gene transfer (plasmids).

Overuse accelerates resistance; stricter prescribing reduces risk.

Completing antibiotic courses reduces survival of resistant bacteria.
