How to do a Kirby-Bauer Disk Diffusion Antimicrobial Susceptibility Test

To learn more about Hardy Diagnostics and our products visit our new website. https://go.hardydiagnostics.com/yt-hardy-diagnostics The purpose of the Kirby-Bauer disk diffusion susceptibility test is to determine the in vitro susceptibility of bacteria and fungi to various antimicrobial compounds. It is a standardized test that can be performed in a laboratory setting and is a valuable tool for both clinicians and microbiologists. The main benefits of this test are the flexibility of drug selection and obtaining overnight results. It is used to help guide the selection of antimicrobials for the appropriate treatment of infections caused by bacteria and fungi. The test is performed by placing antimicrobial impregnated filter paper disks on the surface of an agar-containing medium that has been inoculated with the patient’s microorganism. Upon contact with the agar surface, the antimicrobial agent immediately diffuses from the disk into the surrounding agar where it may inhibit the growth of the microorganism. If the microorganism is inhibited by the antimicrobial agent, a clear zone of ‘no growth’ will be present around the paper disk after incubation. The presence or absence of a zone of inhibition around the disks is a measure of the microorganism’s susceptibility to the antimicrobial agent. The Kirby-Bauer disk diffusion test is a standardized method for determining the susceptibility of bacteria and fungi to various antimicrobial compounds. It is a valuable tool for clinicians and microbiologists and can be used to help guide the selection of antimicrobials for the treatment of bacterial infections. By following these steps and referencing the relevant standards for current procedures, recommendations, and interpretive criteria, you can ensure that your Kirby-Bauer disk diffusion tests are accurate and reliable.
