Science

How the Enterolert Test works

The Enterolert Test uses a proprietary Defined Substrate Technology (DST) nutrient indicator to detect enterococci. This nutrient indicator fluoresces when metabolized by enterococci. DST improves accuracy and avoids the need for hazardous sodium azide suppressants used in traditional media.

Quantification


Step 1

Add reagent to sample.

Step 2

Pour into Quanti-Tray (counts from 1–200) or Quanti-Tray/2000 (counts from 1–2,419).

Step 3

Seal using Quanti-Tray Sealer and incubate for 24 hours at 41°C ± 0.5°C.

Step 4: Quanti-Tray

For counts from 1–200: Count fluorescent wells and refer to most probable number (MPN) table.

Step 4: Quanti-Tray/2000

For counts from 1–2,419: Count fluorescent wells and refer to most probable number (MPN) table.
