1. The size of the zone of inhibition often varies for two different species of bacteria when challenged with the same antibiotic. What is a possible explanation for these differences? 2. Antibiotics can be bactericidal (they kill the microbe) or bacteriostatic (they inhibit microbial growth, but do not kill). When observing a zone of inhibition around a disk, how would you to determine whether the antibiotic causing that zone was bactericidal or bacteriostatic? 3. When performing antibiotic sensitivity testing, it...

LAB EXERCISE #6: Kirby-Bauer Disk Diffusion Test for Antibiotie Sensitivity Determination The Kirby Bauer Test is an agar diffusion test that is used to determine the effectiveness of antibiotics killing various species of bacteria. Filter paper disks saturated with the antibiotic of interest are placed a Mueller-Hinton agar plate on which bacteria that has been isolated from a clinical sample has been sarcad. The antibiotic then diffuses from the disk...
