What plate is used for the Kirby-Bauer test? Mueller-Hinton agar plate zone of inhibition Region around a chemical saturated disc, where bacteria are unable to grow due to adverse effects of the compound in the disc. The larger the zone size, the more ____________ the bacterium is to that antibiotic. susceptible What measurement units are used in the Kirby Bauer test to measure the zone sizes? millimeters MIC test stands for: minimum inhibitory concentration last clear tube: lowest c...
