Verified step by step guidance1
The Kirby-Bauer method is a laboratory test used to determine the effectiveness of antibiotics against specific bacteria.
In this method, small discs containing antibiotics are placed on an agar plate that has been inoculated with the bacteria in question.
As the bacteria grow, they form a lawn on the agar surface, and the antibiotics diffuse from the discs into the agar.
The effectiveness of the antibiotics is indicated by the presence of clear zones around the discs where bacterial growth is inhibited, known as zones of inhibition.
The size of these zones is measured and compared to standard values to determine the susceptibility of the bacteria to the antibiotics.
