Antibiotic sensitivity testing method shown in image is
A. Kirby Bauer disc diffusion method.
B. Stokes disk diffusion method.
C. Broth dilution method.
D. Agar dilution method.
Ans:B. Stokes disk diffusion method
Stokes Disc Diffusion Technique varies from Kirby Bauer disc diffusion in the use of both control and test strain on a same plate. Stokes disc diffusion technique is not as highly standardized as the Kirby-Bauer technique and is used in laboratories particularly when the exact amount of antimicrobial in a disc cannot be guaranteed due to difficulties in obtaining discs and storing them correctly or when the other conditions required for the Kirby-Bauer technique cannot be met.
