Kirby-Bauer Antimicrobial Susceptibility Test
The Kirby-Bauer disc diffusion method is one of several standard methods used to measure susceptibility of bacterial isolates to antibiotics. The susceptibility of bacterial pathogens to numerous antimicrobial agents can be established in a single assay with the Kirby-Bauer method. This site supplies information about the Kirby-Bauer Antimicrobial Susceptibility Test including the purpose, mechanism, method, components and interpretation. In addition, there is a virtual Kirby-Bauer exercise that allows students to simulate the test on one of three randomized assay plates containing Staphylococcus aureus, Escherichia coli, or Pseudomonas aeruginosa which have been tested for susceptibility to 13 various antibiotics.
