- What is the relationship between the zone of inhibition and antibiotic concentration and what is the most effective antibiotic based on this table?Below, 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.)?Does the antibiotic disk producing the largest zone of inhibition on a plate always correspond to the drug you should treat the patient with?
- Why would not the size of the inhibition in the Kirby-Bauer test directly relate to the comparative effectiveness of antibiotics when comparing different antibiotics?What is the spectrum of activity for an antibiotic and why would this be important treating infections? Compare and contrast narrow and broad spectrum antibiotics.Based on class data only, which antimicrobial has the broadest spectrum? Which one has the narrowest spectrum?
- What is this result telling me? The ANCOVA confirmed the hypothesis that the antimicrobial dose response was paralleled between two bacterial species (S. typhimurium and E. faecium), and the interaction between antimicrobial concentrations and bacterial species was not significant (P > 0.05); only the antimicrobial concentrations of H2O2-PAA mixer played a significant (P < 0.05) impact on the inactivation of S. typhimurium and the surrogate bacteria E. faecium on squash.What are the 4 main targets of antimicrobials? Provide the rationale why each is a good target.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 strip
- Spectrum of activity describes how many species of microbes a drug works against. Broad-spectrum antibiotics are effective against many different groups of bacteria, while narrow-spectrum antibiotics work well against a particular group or species, but have little effect on the rest. Based on our class results, which of the following are narrow-spectrum? Group of answer choices Amoxicillin/Clavulanic acid Ampicillin Kanamycin Ciprofloxacin Vancomycin Bacitracin Trimethoprim/Sulfamethoxazolea. Antimicrobial Effectiveness Tesct (AET) is called differently in European Pharmacopeia and Japanese Pharmacopeia, what are these names?Below is a diagram of four different antibiotics (numbered 1-4) that are being tested in a petri dish inoculated with bacteria. After a sufficient incubation period, bacterial growth occurred except in the zones of inhibition (shown with dotted lines in the diagram) around the antibiotics. Based on the results shown here, would it be reasonable to conclude that the most effective antibiotic in this example would be an effective antibiotic against any bacterium? Why or why not?
