Question

Disc diffusion method is also known as:

• A. Kirby Bauer
• B. VDRL
• C. Dark field microscopy
• D. None of these

Answer 1

The Correct Option is A

In microbiology, the disc diffusion method is a technique used to evaluate the effectiveness of antibiotics against bacteria. This method involves placing antibiotic-impregnated paper discs on an agar plate inoculated with the bacteria in question. As the bacteria grow, the antibiotic diffuses from the disc into the agar, inhibiting bacterial growth in a surrounding zone.

This test is commonly referred to as the Kirby Bauer test. It is widely used due to its simplicity, cost-effectiveness, and the ability to compare multiple antibiotics simultaneously.

Given Options:

Kirby Bauer	Correct
VDRL	Incorrect
Dark field microscopy	Incorrect
None of these	Incorrect

Therefore, the correct answer is: Kirby Bauer.
