Kirby-Bauer method

The Kirby-Bauer method is a laboratory test used to determine how effective antibiotics are against specific bacteria. In this process, bacteria are spread on a petri dish, and small discs containing different antibiotics are placed on the surface. After incubation, scientists examine the dish for clear zones around the discs, indicating where the bacteria couldn't grow due to the antibiotic’s effect. The size of these zones helps determine whether the bacteria are resistant or susceptible to the antibiotics tested, guiding doctors in choosing the right treatment for bacterial infections.
