Homework Answers
I believe the correct answer to be:
TRUE.
As for the bacteria to be resistant to tetracyclin, the zone diameter needs to be less than 14mm and in the image above, it can be clearly seen that the zone diameter is 9mm so the bacteria is considered resistant.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

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...
