WebAs the bacterial inoculum grows, antibiotic diffuses from the circular disk into the agar and interacts with the growing bacteria. Antibacterial activity is observed as a clear circular zone of inhibition around the drug-impregnated disk, similar to the disk-diffusion assay depicted in Figure 13.31. The diameter of the zone of inhibition ... Webuniversity, research 425 views, 8 likes, 16 loves, 3 comments, 4 shares, Facebook Watch Videos from Cebu Doctors' University: 1st INTERNATIONAL...
