What does low MIC indicate?

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.

Which testing value range indicates that MIC is OK?

Examples of acceptable MIC values for control strains are: Pseudomonas aeruginosa (ATCC 27853): between 16-32 µg/ml (resistant); Escherichia coli (ATCC 25922): between 0.5-2 µg/ml (susceptible); Staphylococcus aureus (ATCC 29213): between 0.12-1 µg/ml (susceptible) andEnterococcus faecalis (ATCC 29212): between 16-32 …

What does the minimum inhibitory concentration MIC relate to?

In microbiology, the minimum inhibitory concentration (MIC) is the lowest concentration of a chemical, usually a drug, which prevents visible growth of a bacterium or bacteria. MIC depends on the microorganism, the affected human being (in vivo only), and the antibiotic itself.

What is MIC in urine culture report?

Minimal inhibitory concentration (MIC) defines in vitro levels of susceptibility or resistance of specific bacterial strains to applied antibiotic. Reliable assessment of MIC has a significant impact on the choice of a therapeutic strategy, which affects efficiency of an infection therapy.

What is the importance of determining MIC?

The MIC provides the ability to precisely determine the concentration of antibiotic required to inhibit growth of a pathogen. Your IDEXX microbiology results will show the identity of the organism and the appropriate antibiotic sensitivity pattern against each organism.

How do you read a MIC value?

The MIC is reported as a numerical value. Values above or below the range of measurement are indicated with “<=” (in case of below the range, in the susceptible category) or with “>=” (in case of above the range, in the resistant category).

How do you read a bacteria MIC?

The MIC number is the lowest concentration (in μg/mL) of an antibiotic that inhibits the growth of a given strain of bacteria. (See the “What is an MIC?” section.) An MIC number for one antibiotic CANNOT be compared to the MIC number for another antibiotic. (See the “How are MICs used?” section.)
