Validation of MICA Legionella for Enumeration of Legionella pneumophila in sanitary waters and cooling tower waters: AOAC Performance Tested MethodSM #032201.

MICA Legionella is a robust and reliable method for the enumeration of culturable L. pneumophila in domestic and cooling tower waters. It reduces significantly the number of sample pretreatments required in ISO 11731:2017. Automatic identification and enumeration of L. pneumophila microcolonies eliminates the requirement to have skilled analysts and limits the results variability. It also greatly reduces the time to results to 48 hours instead of 7-10 days with the ISO 11731:2017 while providing statistically equivalent results.
