The MIC mode indicates the most frequently measured MIC related to an isolate and agent.
Data are from testing five isolates in five independent replications.
Percentage of MIC values corresponding to the MIC mode of the isolates.
The essential MIC agreement allows a deviation of ±1 dilution step from the MIC mode.
The MIC value of at least one isolate was equal to, lower, or higher than the concentration of the test range.
Data that fulfill the criteria of the essential MIC agreement are highlighted in gray.
