Question

What is the difference between a disk-diffusion test and a kirby-Bauer test? Why is Mueller-hinton agar used in the kirby-bauer test?

Answer 1

The Kirby-Bauer test and disk diffusion are the same.

Step-by-step explanation:

Kirby-Bauer antibiotic disk diffusion is used for bacterial susceptibility testing. Mueller-hinton (MH) agar is used as it is the best medium for daily antibiotic testing as it supports growth of non-fastidious organisms. Furthermore, MH controls the rate of antibiotic diffusion through the agar.
