[9] [10] MIC values provide a quantitative measure of an extract or compound's antimicrobial potency. The lower the MIC, the more potent the antimicrobial. [4] When in vitro toxicity data is available, MICs can also be used to calculate selectivity index values, a measure of off-target to target toxicity. [4]
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]
The minimum bactericidal concentration (MBC) is the lowest concentration of an antibacterial agent required to kill a particular bacterium. [1] It can be determined from broth dilution minimum inhibitory concentration (MIC) tests by subculturing to agar plates that do not contain the test agent.
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 ...
The minimum inhibitory concentration, which is the lowest concentration of the antibiotic that stops the growth of bacteria, can be estimated from the size of the zone of inhibition. Antibiotic susceptibility testing has been needed since the discovery of the beta-lactam antibiotic penicillin. Initial methods were phenotypic, and involved ...
The following represents MIC susceptibility data for a few medically significant bacteria: [12] Haemophilus influenzae: 0.015 to 256 μg/ml; Staphylococcus aureus: 0.023 to 1024 μg/ml; Streptococcus pyogenes: 0.004 to 256 μg/ml; Corynebacterium minutissimum: 0.015 to 64 μg/ml; It may be useful in treating gastroparesis due to this ...

Aminoglycosidic antibiotics are usually considered bactericidal, although they may be bacteriostatic with some organisms. As of 2004, the distinction between bactericidal and bacteriostatic agents appeared to be clear according to the basic/clinical definition, but this only applies under strict laboratory conditions and it is important to ...
