The Kirby-Bauer disk diffusion method was used to determine the effectiveness of several antibiotics against Pseudomonas aeruginosa. Based on the following data, which antibiotic was most effective? Antibiotic J with a zone of inhibition of 7 mm Antibiotic P with a zone of inhibition of 1 mm Antibiotic M with a zone of inhibition of 2 mm Antibiotic H with a zone of inhibition of 14 mm Antibiotic Y with a zone of inhibition of 10 mm

In this method, paper disks containing different antibiotics are placed on a plate that has been inoculated with the bacteria of interest. The antibiotics diffuse out from the disks into the agar, creating a concentration gradient. If the antibiotic is effective 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.
