Answer :
Final answer:
The Kirby-Bauer disk diffusion test measures the effectiveness of antibiotics against bacteria by observing the size of inhibition zones around disks on an agar plate. MRI scans help in diagnosing conditions like disk infection and degenerative disk disease by providing detailed images of affected areas.
Explanation:
The Kirby-Bauer disk diffusion test is a method used to determine the susceptibility of bacteria to antimicrobial drugs. In this test, disks impregnated with specific antibiotics are placed on an agar plate inoculated with a bacterial lawn. The effectiveness of the antibiotics is determined by measuring the zones of inhibition that form around these disks, with larger zones indicating greater bacterial susceptibility to the antibiotic.
Magnetic resonance imaging (MRI) can be utilized for detection of different conditions affecting the human body such as joint damage, and narrowing of the spinal disk space. When it comes to differentiating between disk infection and degenerative disk disease, MRI scans provide high-resolution images that help in determining the presence and extent of either condition.
