Explanation:
The Kirby-Bauer test is a technique used in laboratories to assess the sensitivity of bacteria to antibiotics. This is one of the most reliable sensitivity tests in the world and is used in several areas such as health, agriculture, zoology, among others.
The test is done by applying antibiotic discs to a petri dish containing culture medium and a growing bacterium. When the bacterium grows inside the plate, it is observed whether the antibiotic discs were able to cause zones of inhibition of this growth.
Bacteria that do not have zones of inhibition are considered resistant to antibiotics, whereas bacteria that have zones of inhibition are considered susceptible.
