MIC 50 and MIC 90 refer to the minimum inhibitory concentration values at which 50% and 90% of the tested microbial strains are inhibited, respectively. To calculate these values, you first arrange the MIC results from a susceptibility test in ascending order. MIC 50 is the median value, found at the 50th percentile, while MIC 90 is the value at the 90th percentile, meaning it is the concentration at which 90% of the isolates show inhibition. You can use statistical software or manual calculations based on the distribution of your MIC data to determine these percentiles.

What is MIC90 and MIC50?

The MIC50 and MIC90 is a way of recording antibiotic sensitivities more conviniently, especially if your trying to report MICs of a large group or organisms. The MIC 50 would show that 50% of the organisms lie below this MIC, e.g an MIC50 of 32 shows that 50% of your organisms have an MIC of 32 less and the same principal for the MIC90. This just shows that 90% of your organisms lie below that MIC eg. MIC 90 of 128 means 90% of your organisms are at 128 or below so this represents the majority or average.


How do you calculate the MIC90?

The MIC90 (Minimum Inhibitory Concentration at which 90% of the tested strains are inhibited) is calculated by determining the MIC values for a set of microbial isolates against a specific antimicrobial agent. After obtaining the MIC values, they are sorted in ascending order. The MIC90 is identified as the MIC value that corresponds to the 90th percentile of the sorted list, meaning that 90% of the isolates have MIC values equal to or lower than this concentration.


Why MIC 90 Not MIC 100?

MIC 90 refers to the minimum inhibitory concentration at which 90% of a specific bacterial population is inhibited by an antimicrobial agent, while MIC 100 indicates the concentration needed to inhibit 100% of the population. MIC 90 is often preferred in clinical settings because it provides a more practical benchmark for effective treatment, accounting for inherent variability in bacterial susceptibility. MIC 100 may be too stringent, as it doesn't consider the potential for successful treatment at lower concentrations that still effectively manage the infection. Thus, MIC 90 balances efficacy with practicality in therapeutic applications.


What is an MIC 90 as a measure of antibiotic activity?

MIC 90 refers to the minimum inhibitory concentration (MIC) at which 90% of a particular bacterial population is inhibited by an antibiotic. It is a useful measure to determine the effectiveness of an antibiotic against a specific microorganism. MIC values help clinicians select the most appropriate antibiotic therapy for treating infections.

How to calculate a percentage?

It depends on what you're trying to calculate a percentage for. On a homework, test, or other scholastic assignment it would be:Total Points Earned ÷ Total Points Possible.Example: 45 points earned on a test totaling 50 points. 45 ÷ 50 = .90 or 90%
