Minimum Inhibitory Concentration (MIC)

Introduction to Minimum Inhibitory Concentration (MIC)

The minimum inhibitory concentration (MIC) is the lowest concentration of an antimicrobial agent that inhibits the visible growth of a microorganism after overnight incubation. In microbiology, the MIC is a key parameter used to determine the effectiveness of antibiotics and other antimicrobial agents against specific organisms. The formula for MIC is the product of the concentration of the antimicrobial agent and the dilution factor.

Parameter usage:

• concentration= concentration of the antimicrobial agent
• dilution= dilution factor

Output:

• MIC= minimum inhibitory concentration

Data validation

The concentration and dilution should be non-negative numbers. Zero dilution or zero concentration would result in MIC of 0.

Summary

This calculator provides the minimum inhibitory concentration (MIC) value based on the concentration of the antimicrobial agent and the dilution factor.
