please asap ty!!! 4. In the Kirby-Bauer susceptibility testing method: (5) a. Why must the standard suspension of organism be inoculated within 15 minutes? How will it affect the zone size?
Kirby-Bauer susceptibility testing method: b. What can happen to the zone of the inhibition if the disks are placed on the plate more than 15 minutes after inoculation?
Kirby-Bauer susceptibility testing method: What may happen to the zone of inhibition if the plate is left out at room temperature for more than 15 minutes after the disks are applied?
Colonies in the zone represent resistant bacteria.

1. How can you prove that antibiotic used in Kirby-Bauer (disk diffusion) test is bactericidal? How would you explain the presence of isolated colonies within an otherwise clear zone of inhibition produced in Kirby-Bauer (disk diffusion) test?
The following is staphylococcus aureus disk diffusion (Kirby-Bauer) antibiotic testing Which antibiotic could be selected as the best? Why? (justify your answer). Antibiotics - Testing Sensitivity Kirby-Bauer Method Staphylococcus aureus Chloramphenicol Lawn of IP vin. Streptomycin Streptomycin
While reading a disk diffusion susceptibility test, you notice a faint haze of growth to the edge of the sulfamethoxazole disk and a more pronounced zone that measures in the sensitive range. Is the drug S, I, or R? Explain your answer.
The physician orders a lab technician to perform a Kirby Bauer disk diffusion assay and finds that the organism is resistant to the following antibiotics: 1) Penicillin, 2) Ampicillin, 3) Methicillin, and 4) Trimethoprim/Sulfamethoxazole. The physician asks the man about any drug allergies and other pre-disposing factors that could impact anti-microbial therapy. The man is allergic to all of the beta-lactam antibiotics, all cephalosporins, and does not tolerate sulfa drugs well. The man also has a form of hepatitis from...
