If pathogen A is more resistant to an erythromycin disc on a Kirby-Bauer plate compared to B, then A will have a smaller zone of inhibition compared to B.
<h3>What is the zone of inhibition?</h3>
The zone of inhibition can be defined as a circular region in a plate where pathogenic agents cannot grow.
This zone (zone of inhibition) can determine the action of different drugs like antibiotics for a given disease.
The zone of inhibition test is also widely known as the Kirby-Bauer Test due to their developers.
