The Disk-Diffusion Test is Used For

Question

The disk-diffusion test is used for
A) assessing antimicrobial activity.
B) the identification of Escherichia coli.
C) the identification of viral plaques.
D) the detection of antigen.

Accepted Answer

The disk-diffusion test is commonly used to assess antimicrobial activity. It involves placing antibiotic-containing disks onto a culture plate and measuring the zone of inhibition around each disk, indicating the effectiveness of the antibiotic against the bacteria present in the culture. It is widely used in clinical and research settings to determine the sensitivity of bacteria to various antibiotics. The other options (B, C, and D) do not involve the disk-diffusion test.
