Antimicrobial susceptibility tests are used to determine the most effective antibiotic to treat a bacterial infection. It helps guide clinicians in selecting the appropriate antibiotic therapy for patients, taking into account the sensitivity of the bacteria to specific drugs. This test helps prevent the overuse of broad-spectrum antibiotics and reduce the development of antibiotic resistance.
Yes, it is necessary to test the antimicrobial susceptibility of each isolate to determine their individual susceptibility profiles and guide appropriate treatment for each patient. Despite isolates being from the same species, they can exhibit different resistance patterns which may impact treatment decisions.
Antimicrobial resistance is similar to antibiotic resistance. Microbes evolve to survive exposure to both antimicrobials and antibiotics when such products are used excessively or inappropriately.
Minimum inhibitory concentration (MIC) is the lowest concentration of an antimicrobial drug that prevents the visible growth of a microorganism in a test tube. It is used to determine the effectiveness of an antimicrobial agent against a specific pathogen. MIC values are important in guiding treatment decisions and understanding the susceptibility of microorganisms to different antibiotics.
In the disk diffusion test (also called the Kirby Bauer test), disks containing an antimicrobial agent are placed on the surface of an agar plate containing a medium that has been inoculated with the disease agent being tested, which will grow and fill the disk. The antimicrobial agent diffuses into the medium, killing some of the disease agent around where the anitmicrobial agent was innoculated, depending on how susceptible the disease agent is to the antimicrobial agent. The size of the area cleared of the disease agent shows how effective the antimicrobial agent is.
The agar dilution test is a method used in microbiology to determine the minimum inhibitory concentration (MIC) of an antimicrobial agent against a particular microorganism. It involves placing different concentrations of the antimicrobial agent on agar plates inoculated with the microorganism and observing which concentration effectively inhibits its growth. The MIC is the lowest concentration of the antimicrobial agent that prevents visible growth of the microorganism.
Antimicrobial susceptibility is a test that is used to see which antibiotics will fight off a bacteria or fungus. There are several different kinds of antimicrobial susceptibility tests currently being used.

A bacteria which is harmed, inhibited or killed by the antibiotic
Susceptibility studies, antimicrobial agent; microdilution or agar dilution, each multi-antimicrobial, per plate
Antimicrobial resistance is similar to antibiotic resistance. Microbes evolve to survive exposure to both antimicrobials and antibiotics when such products are used excessively or inappropriately.
The recommended method for measuring the zone of inhibition in antimicrobial susceptibility testing is to use a ruler to measure the diameter of the clear area around the antibiotic disk where bacterial growth is inhibited. This measurement helps determine the effectiveness of the antibiotic against the bacteria being tested.

A sensitivity test, also called antibiotic susceptibility test
To determine a persons susceptibility to diphtheria.

The Mueller-Hinton agar was named after John Hinton and Jane Hinton, who developed this medium in 1941 as a suitable medium for the standardized antimicrobial susceptibility testing. The Mueller-Hinton agar is still widely used today for antibiotic susceptibility testing.
