    The Kirb-Bauer Disk Diffusion Technique

    The Kirb-Bauer Disk Diffusion Technique was performed on 2 different Mueller-Hinton Agar plates.
    One plate had Escherichia Coli spread on it and the other plate has Staphylococcus Epidermidis spread on it.

    Both plates had ampicillin, penicillin, vancromicin and ethromycin placed on it.

    What would be the zone of inhibition for each antibiotic on each plate (The E Coli plate & and the Staphylococcus Epidermidis)?

    Exact numbers are not needed you can just list them from largest zone of inhibition to no zone of inhibition for each of the two plates.

    The Kirby-Bauer plates are designed to test antibiotic efficiency by allowing the growth of choice microbes in the dish and exposing them to different antibiotics. The zone of inhibition refers to the microbe free zone around the core of the antibiotic wells in the gel. As one can imagine, as the antibiotic diffuses across the gel, eventually at a certain distance away from the ...

    Solution Summary

    The Kirb-Bauer disk diffusion technique is examined. The exact numbers needed are determined.
