The End Zone: Measuring Antimicrobial Effectiveness with Zones of Inhibition Introduction: A Kirby-Bauer test is a microbiological method used as a form of testing bacterial resistance, it’s also known as a Zone of Inhibition test (1). The way in which the Zone of Inhibition was determined in this experiment was by measuring the diameter of the resisted zone in 3 areas and taking an average. As numerical data was required for this it means that in this experiment the Zone of Inhibition Test was…
