You perform a Kirby-Bauer assay with two antibiotics. Antibiotic X has a zone of inhibition of 3 mm. Antibiotic Y has a zone of inhibition of 5 mm. Which antibiotic is better at killing this particular microorganism? A. Antibiotic Y B. It is impossible to tell from the information given. C. Antibiotic X and Y, which have identical antimicrobial activities D. Antibiotic X

Step 1
In a Kirby-Bauer assay, a paper disk containing a specific antibiotic is placed on a culture of bacteria. If the antibiotic is effective against the bacteria, it will prevent the bacteria from growing around the disk, creating a clear zone of inhibition. In this Show more…

Upon performing a Kirby-Bauer disc diffusion test using Staphylococcus aureus, you observe no zone of inhibition with penicillin and a 15mm zone of inhibition with vancomycin. Based on these observation, which of the following conclusions is valid? Penicillin is bactericidal toward Staphylococcus aureus, and vancomycin is bacteriostatic toward S. aureus. Staphylococcus aureus is resistant to both vancomycin and penicillin. Staphylococcus aureus is resistant to penicillin and sensitive to vancomycin. Staphylococcus aureus is resistant to penicillin but may or may not be sensitive to vancomycin.

Suppose you do the Kirby-Bauer test on a hypothetical Staphylococcus species with penicillin and tetracycline. You record diameters of 20mm for tetracycline and 24mm for penicillin. Which antibiotic is most effective against this bacterium and why? Please explain and interpret these results.
