This question asks, in the kirby -bower disk diffusion test, the blank of the zone of inhibition is measured and used for interpretation.
00:12
So our answer choices are diameter, microbial population, circumference, and depth.
00:18
So if we look at the figure presented here, we see the procedure in which the kirby -bower test is performed.
00:25
So first, we see that we dispense our antibiotic disks using this dispenser onto an agarplate, and we see that these antibiotic disks will be approximately equidistant from one another on this agarplate.
00:47
So then we would touch the disc with a sterile applicator or forceps, and after incubation, we will measure the diameter of each zon.
00:58
Zone of inhibition with millimeter rulers.
01:02
So as you see here, we have bacterial growth all around the agroplate except for this zone of inhibition...
