Method for the determination of minimum inhibitory

Dilution methods are used to determine the minimum inhibitory concentrations (MICs) of antimicrobial agents and are the reference methods for antimicrobial susceptibility testing. In dilution tests, microorganisms are tested for their ability to produce visible growth in microtitration plate wells of broth (broth microdilution) containing serial dilutions of the antimicrobial agents.

Agar dilution

Agar dilution is one of two methods (along with Broth Dilution) used by researchers to determine the Minimum Inhibitory Concentration (MIC) of antibiotics. It is the dilution method most frequently used to test the effectiveness of new antibiotics when a few antibiotics are tested against a large panel of different bacteria.

Minimum Inhibitory Concentration (MIC) Testing

Minimum Inhibitory Concentration (MIC) assays determine the lowest concentration of an antimicrobial agent that prevents visible growth of a microorganism. Minimum Bactericidal Concentration (MBC) and Minimum Fungicidal Concentration (MFC) assays determine the lowest concentration of an antimicrobial agent required to achieve bactericidal and fungicidal killing, defined as a 99.9% reduction

Measuring Drug Susceptibility

Minimum inhibitory concentration (MIC) can be determined by culturing microorganisms in liquid media or on plates of solid growth medium. A lower MIC value indicates that less drug is required for inhibiting growth of the organism; therefore, drugs with lower MIC scores are more effective antimicrobial agents.

Minimum Inhibitory concentration (MIC): Broth dilution

This results in a 1:2 dilution of each antimicrobial concentration and a 1:2 dilution of the inoculums. Incubation: Incubate the inoculated tubes at 35 2 C for 16 to 20 hours in an ambient air incubator. To maintain the same incubation temperature for all cultures, do not stack microdilution trays more than four high. Interpretation

Minimum Inhibitory (MIC) and Minimum Bactericidal

It can be determined from the broth dilution of MIC tests by subculturing to agar plates that do not contain the test agent. The MBC is identified by determining the lowest concentration of antibacterial agent that reduces the viability of the initial bacterial inoculum by a pre-determined reduction such as ≥99.9%.

Microbiology Guide to Interpreting Minimum Inhibitory

The MIC, or minimum inhibitory concentration, is the lowest concentration (in μg/ml) of an antibiotic that inhibits the growth of a given strain of bacteria. At IDEXX, a commercial automated system is used to determine MICs. A quantitative method of susceptibility testing, an MIC helps determine which class of antibiotic is most effective.
