Answer #1

Kirby-Bauer test is also called the Disk diffusion test. This test is used to identify the sensitivity of microorganisms like certain bacteria against particular antibodies. If it is sensitive, then there will be no organisms near the antibiotic disks. This means that there will be a zone of clearance around the disk. But if the organism is resistant then there will be growth around the disks.

Standardization is used to look for the standard result. This must be a positive result. This means that there should be sensitivity, no growth, and large zones. In order to standardize this experiment, the procedures are carried out under standardized conditions and then the standard size of zones for each antibiotic is recorded.
