Which of the following describes the 'post-antibiotic effect' (PAE) of beta-lactams against Gram-negative bacteria?
Show answer and explanation
Correct answer: Minimal to no PAE
Beta-lactams generally exhibit a very short or non-existent PAE against Gram-negative organisms. This means that to be effective, their concentration must remain above the Minimum Inhibitory Concentration (MIC) for most of the dosing interval.
