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.

Step 1
The Kirby-Bauer test is a method used to determine the susceptibility of bacteria to different antibiotics. In this test, antibiotic-impregnated disks are placed on an agar plate that has been inoculated with the bacteria of interest. The antibiotics diffuse out Show more…

Suppose you do this test on a hypothetical Staphylococcus species with the antibiotics penicillin (P 10) and chloramphenicol (C 30). You record zone diameters of 25 mm for the chloramphenicol and penicillin disks. Which antibiotic would be more effective against this organism? What does this tell you about comparing zone diameters to each other and the importance of the zone diameter interpretive table?

Suppose you do this test on hypothetical Staphylococcus species with the antibiotics penicillin (P-10) and chloramphenicol (C30). You record identical zone diameters of 25 mm for the chloramphenicol and penicillin disks. Which antibiotic would be more effective against this organism? What does this tell you about comparing zone diameters to each other and the importance of the zone diameter interpretive chart?

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.
