How the Legiolert Test works
The Legiolert Test detects Legionella pneumophila in water samples. This test is based on a bacterial enzyme detection technology that signals the presence of Legionella pneumophila through utilization of a substrate present in the Legiolert reagent. Legionella pneumophila cells grow rapidly and reproduce using the rich supply of amino acids, vitamins, and other nutrients present in the Legiolert reagent. Actively growing strains of Legionella pneumophila use the added substrate to produce a brown color indicator. The Legiolert Test detects Legionella pneumophila at 1 organism in 100 mL within 7 days.
10 mL protocol
Prepare 1:10 dilution of potable water sample in sterile diluent.
Add reagent to water sample and shake to dissolve.
Pour sample into Quanti-Tray/Legiolert.
Seal using the Quanti-Tray Sealer PLUS and incubate for 7 days.
Read results: Any brown and/or turbid wells are positive for Legionella pneumophila.
Quanti-Tray/Legiolert provides Most Probable Number (MPN)results up to 2,272 per 100 mL sample.
