Theory 04/Speed vs Accuracy/Antibiotics

Fast Kill Selects Resistance

The claim

Antibiotic regimens that kill quickly trade against resistance emergence, because rapid killing leaves a larger window in which surviving cells face strong selection.

01Mechanism

Fast killing clears susceptible cells and leaves resistant persisters with less competition; slower killing maintains competition that suppresses the resistant minority.

02Prediction

Faster killing should select resistance more strongly at equal clearance.

03Refutation

Resistance independent of killing rate would remove the trade-off.
