For this question, it may be helpful to understand what a kirby -barrer susceptibility test is.
00:05
So in this test, they take a plate of auger, they're going to inoculate it with an initial bacterial species, and they're going to place different antibiotic disks equally spaced around inside the gel.
00:23
They're going to incubate the plate for, say, 24 -48 hours.
00:28
They'll come back, and they're going to investigate for bettureate.
00:32
Growth around each of these disks.
00:37
So after the incubation, you'll have, say, a more cloudy area on the outside, and you'll have these more clear zones that surround each of the antibiotics.
00:49
Now, when a scientist looks at these, they're going to measure the diameter across these circles, or what we call the zone of inhibition.
00:58
And these measurements will relate to whether the organism is resistant to that antibiotic, whether it's intermediately resistant, or whether it's completely susceptible.

And the patient with an infection of this bacterium would be able to be treated with this antibiotic...
