  2. Antibiotic sensitivity testing - Wikipedia

    en.wikipedia.org/wiki/Antibiotic_sensitivity_testing

    The MIC is compared to standard threshold values (called "breakpoints") for a given bacterium and antibiotic. [28] Breakpoints for the same organism and antibiotic may differ based on the site of infection: [29] for example, the CLSI generally defines Streptococcus pneumoniae as sensitive to intravenous penicillin if MICs are ≤0.06 μg/ml ...

  3. Minimum inhibitory concentration - Wikipedia

    en.wikipedia.org/wiki/Minimum_inhibitory...

    In microbiology, the minimum inhibitory concentration (MIC) is the lowest concentration of a chemical, usually a drug, which prevents visible in vitro growth of bacteria or fungi. [1] [2] MIC testing is performed in both diagnostic [1] [2] and drug discovery laboratories. [3] [4]

  4. Antimicrobial pharmacodynamics - Wikipedia

    en.wikipedia.org/wiki/Antimicrobial_pharmacodynamics

    The minimum inhibitory concentration (MIC) and minimum bactericidal concentration are used to measure in vitro activity of antimicrobial agents. They are good indicators of antimicrobial potency, but don't give any information relating to time-dependent antimicrobial killing (the so-called post antibiotic effect). [1]

  5. Etest - Wikipedia

    en.wikipedia.org/wiki/Etest

    A strain of bacterium or fungus will not grow near a concentration of antibiotic or antifungal if it is sensitive. For some microbial and antimicrobial combinations, the results can be used to determine a minimum inhibitory concentration (MIC). Etest is a proprietary system manufactured by bioMérieux. It is a laboratory test used in healthcare ...

  6. Disk diffusion test - Wikipedia

    en.wikipedia.org/wiki/Disk_diffusion_test

    The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture-based microbiology assay used in diagnostic and drug discovery laboratories. In diagnostic labs, the assay is used to determine the susceptibility ...

  7. Vancomycin-resistant Staphylococcus aureus - Wikipedia

    en.wikipedia.org/wiki/Vancomycin-resistant...

    The diagnosis of vancomycin-resistant Staphylococcus aureus (VRSA) is performed by performing susceptibility testing on a single S. aureus isolate to vancomycin. This is accomplished by first assessing the isolate's minimum inhibitory concentration (MIC) using standard laboratory methods, including disc diffusion, gradient strip diffusion, and automated antimicrobial susceptibility testing ...

  8. Antibiotic - Wikipedia

    en.wikipedia.org/wiki/Antibiotic

    An antibiotic is a type of antimicrobial substance active against bacteria.It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections.

  9. Bactericide - Wikipedia

    en.wikipedia.org/wiki/Bactericide

    Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics slow their growth or reproduction. Bactericidal antibiotics that inhibit cell wall synthesis: the beta-lactam antibiotics ( penicillin derivatives ( penams ), cephalosporins ( cephems ), monobactams , and carbapenems ) and vancomycin .
