- What are the tests to determine the level of antimicrobial activity of a antimicrobial agent? How dilution susceptibility and disk diffusion test can be used to determine the effectiveness of a drug?What is the purpose of the antimicrobial susceptibility test? What information can you gather from this method?Ex. 17: Chemotherapeutic Agents Using the Antimicrobial Susceptibility Table on pg 62 in the lab manual, determine whether not the bacteria plated in this Kirby-Bauer test are resistant (R), intermediate (I), or susceptible (S). The bacterial species tested was Escherichia coli (Gram negative). Ciprofloxacin Diameter = 20 Streptomycin Diameter 30 Carbenicillin Diameter 17 + Erythromycin Diameter = 23 Novobiocin Diameter = 0 bacterial growth = disk with antibiotic (see labels) = no growth
- The Kirby -Bauer antimicrobial sensitivity testing method relies on: A. The inhibition of one antimicrobial by another B. The diffusion of antimicrobials in paper discs C. Serial dilutions of antimicrobials in test tubes D. A gradient of an antimicrobial on a paper stripBelow, you can see a picture of an antimicrobial drug. Regarding semi-synthetic antimicrobial drug development to try to avoid development of antibiotic resistance, use 1 sentence to address what is the significance/value of the presence of the various R-groups (e.g. R4, R5, R6, etc.)?If you have 4 compounds and you test them for antimicrobial activity using a disk diffusion assay and one is very active, one is moderately active, one is slightly active and one is not active at all, draw the disk, the zone of inhibition that you would see and a pretend numerical value to indicate the size of the zone in mm, give each one a number 1 – 4 and rank them from most effective to least effective as an antimicrobial.
- Centrifugation is the first step in most fractionations, but it separates only components that differ greatly in size. Compare and contrast very high, high, medium, and low-speed centrifugations of supernatant mixtures. Define the following: SDS Polyacrylamide-Gel Electrophoresis and ImmunoprecipitationPlease discuss how the Methyl Red-Vogues Proskauer test helps distinguish microbes from each other.Why is it necessary to prepare both NSS and Iodine Smears?
