Kirby Bauer - Disc Diffusion Method for Antibiotic Susceptibility Testing

This video explains about Kirby Bauer - Disc Diffusion Method for Antibiotic Susceptibility Testing.

The Kirby-Bauer test is the most widely used antibiotic sensitivity test.

This is also known as Disk Diffusion test.

Filter paper disc containing various antibiotics are placed on a culture plate freshly streaked bacterial colony.

Plates along with the discs incubated at 37degC in an incubator and zone of inhibition is measured.
