<P> The agar diffusion test ( Kirby -- Bauer antibiotic testing , KB testing , or disc diffusion antibiotic sensitivity testing ) is a test of the antibiotic sensitivity of bacteria . It uses antibiotic discs to test the extent to which bacteria are affected by those antibiotics . In this test , wafers containing antibiotics are placed on an agar plate where bacteria have been placed , and the plate is left to incubate . If an antibiotic stops the bacteria from growing or kills the bacteria , there will be an area around the wafer where the bacteria have not grown enough to be visible . This is called a zone of inhibition . </P>
