Flashcards in Exercise 19 - Antibiotic Sensitivity Testing Deck (8)
What is the name of the media used in the Kirby Bauer method
How are the bacteria plated on the media? Lawn?
Spread all over the plate with a q-tip
Or you lawn them with the metal triangle instrument
What is the general procedure of the experiment in exercise 19
1. Swab the entire surface of petri with a bacteria
2. Place antibiotic disks on the agar
3. After incubation, measure zones of inhibition
Zones of Inhibition: how are the measurements taken and which metric units are the answers expressed in?
With a ruler measuring the diameter of zone of inhibition
Know how to read a chart of antibiotics listing the zone diameters and correctly designate the bacteria to be: R, I, S to that antibiotic
What does R, I, S stand for
Which bacteria is the most resistant to the antibiotics?
