What is dilution susceptibility test?
Broth and agar dilution susceptibility testing methods are used to determine the minimal concentration, usually in micrograms per milliliter, of an antimicrobial agent required to inhibit or kill a microorganism.
How does agar dilution method work?
Agar dilution involves the incorporation of different concentrations of the antimicrobial substance into an agar medium followed by the application of a standardized number of cells to the surface of the agar plate. Plates are read by observing the lowest drug concentration that inhibits visible bacterial growth.
Why is there a zone of inhibition?
The Zone of inhibition is a circular area around the spot of the antibiotic in which the bacteria colonies do not grow. The zone of inhibition can be used to measure the susceptibility of the bacteria to wards the antibiotic.
What if there is no zone of inhibition?
A lack of visual zone does not mean the antimicrobial agent is ineffective: the zone of inhibition test requires the antimicrobial agent to migrate into the nutrient agar. If the antimicrobial is not compatible with the nutrient agar, it will not migrate to create a visual zone of inhibition.
What does a bigger zone of inhibition mean?
Large zones of inhibition indicate that the organism is susceptible, while small or no zone of inhibition indicateresistance.
What affects the zone of inhibition?

Why Antibiotics target bacteria but not human cells?
Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium.
What are the factors that influence the Kirby-Bauer method?
The disc diffusion techniques most commonly used (the Kirby-Bauer and Stokes’s tests) take account of important factors, including the inoculum density, the composition of the medium, the delay between application of the disc and incubation, the temperature ofincubation, etc., but the resulting zone of inhibition is …
