Describe the Bauer-Kirby Test. measures sensitivity of bacteria to antibiotics by culturing bacteria on solid growth media surrounding sources of drug. Explain the significance of colonies observed growing in the zone of inhibition in a Bauer-Kirby Test. the size of the zone of inhibition indicates the degree of sensitivity of bacteria to a drug. In general, a bigger area of bacteria-free media surrounding an antibiotic disk means the bacteria are more sensitive to the drug the disk con...

KIRBY-BAUER DISC DIFFUSION METHOD other term for antibiotic susceptibility test Zones of growth inhibition surrounding each type of disc were correlated with the minimum inhibitory concentrations of each antimicrobial agent. Principle: antibiotic susceptibility testing is often essential in order to determine which antibiotics to use against a specific strain of bacterium. Significant: culture and susceptibility test is the growth of a known pathogen in pure culture and ...

What are the two types Kirby-Bauer / Disc Diffusion Minimum Inhibitory Concentration What media do you use for Kirby-Bauer ? Muller-Hinton BBL Prompt Inoculation System Touch 5 colonies with tube like wand. place in tube mix What way should you swab the plate Lawnx3 Must label what side ? Lid side so you can measure the diameters Minimum Inhibitory Concentration Minimum conentration for bacteria Example ofna time when you woulduse this kindnof tes...

Antimicrobial Susceptibility testing -To determine which antimicrobial agents might be effective in treating infections -Need to disntinguish pathogens from commensals -Generally disk diffusion or dilution Reasons for Antimicrobial susceptibility -Suspect a isolate is involved in patient infection -Susceptibility against particular antimicrobial is uncertain Group A strep Susceptible to penicillin Epidemiological Cut-off valves (ECV) Helps identify emerging resi...
