Kirby-Bauer method only tells the bactericidal effect of the antibiotic and not the bacteriostatic effect. If an antibiotic is bacteriostatic then the cells around the disk shouldnt multiply which is the case in normal cells also and no zone of inhibition occurs. Hence the given statement is FALSE.
If you have any query kindly comment before giving thumbs up. Thank you.

The physician orders a lab technician to perform a Kirby Bauer disk diffusion assay and finds that the organism is resistant to the following antibiotics: 1) Penicillin, 2) Ampicillin, 3) Methicillin, and 4) Trimethoprim/Sulfamethoxazole. The physician asks the man about any drug allergies and other pre-disposing factors that could impact anti-microbial therapy. The man is allergic to all of the beta-lactam antibiotics, all cephalosporins, and does not tolerate sulfa drugs well. The man also has a form of hepatitis from...

Antibiotic Resistant in mm Intermediate(mm) Susceptible (mm) Cefotaxime 11 12-13 ________ A. What would the minimum zone diameter be in this test that would indicate the organism is susceptible? ___________ B.

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? Staphylococcus aureus is resistant to penicillin and sensitive to vancomycin. Staphylococcus aureus is resistant to both vancomycin and penicillin. Staphylococcus aureus is resistant to penicillin but may or may not be sensitive to vancomycin. Penicillin is bactericidal toward Staphylococcus aureus, and vancomycin is...

A clinical researcher performed a modified Kirby-Bauer assay on a bacterium cultured from a patient. The following is a summary of the assay performed: The clinician spread the surface of several Mueller-Hinton agar plates (a media type containing beef extract, casein, and starch) with the bacterial culture using aseptic technique. Next, they applied sterile antibiotic disks, each containing a different antibiotic to the surface of the plates. After the agar plates were incubated overnight, the clinician measured the diameter of...

LAB EXERCISE #6: Kirby-Bauer Disk Diffusion Test for Antibiotie Sensitivity Determination The Kirby Bauer Test is an agar diffusion test that is used to determine the effectiveness of antibiotics killing various species of bacteria. Filter paper disks saturated with the antibiotic of interest are placed a Mueller-Hinton agar plate on which bacteria that has been isolated from a clinical sample has been sarcad. The antibiotic then diffuses from the disk...

Question 14 1 pts TRUE/FALSE: In order to optimize a differentiable function f(x, y)over the disk (filled in circle) x2 + y2 < 4, you first find all critical points in that disk, and then sort them by output. Then, you use the method of Lagrange Multipliers (perhaps) to optimize the function on the boundary circle. Finally, you compare all special points and circle the biggest/smallest outputs and type them into webassign. True O False
