Remel™ Listeria Enrichment Broth, Dehydrated

Selectively isolate and cultivate Listeria monocytogenes using Thermo Scientific™ Remel™ Listeria Enrichment Broth (Dehydrated). Listeria Enrichment Broth (Dehydrated) was developed as an alternative to the cold enrichment procedure¹. It is recommended by the Food and Drug Administration and the American Public Health Association (APHA) for testing dairy products. The use of broth enrichment procedure improves isolation of low numbers of L. monocytogenes.

Listeria monocytogenes is a common contaminant in raw milk, meats, vegetables, seafood, and in the food processing environment^2,3. This method used to promote growth of potentially injured cells helps in successful recovery of Listeria from food and environmental sources while simultaneously inhibiting non-Listeria background organisms⁴.

• Selective medium - Cycloheximide, acriflavine, and nalidixic acid inhibit frequently encountered background organisms.
• Recommended by the Food and Drug Administration and the American Public Health Association (APHA) for testing dairy products.

The medium contains casein peptone and soy peptone which provide nutrients necessary for bacterial growth. Bacterial growth is stimulated by B-complex vitamins supplied by yeast extract. Dextrose is the carbohydrate source. Dipotassium phosphate acts as a buffering agent whereas sodium chloride provides essential electrolytes and maintains osmotic equilibrium. Selective agents such as cycloheximide, acriflavine, and nalidixic acid inhibit frequently encountered background organisms.
