Listeria Enrichment Broth with Supplements is a modification of Listeria Fraser Broth ISO Cat. 1182 used in the rapid detection of Listeria from food and environmental samples. The antibiotics are already included in the formula. The medium is used for the selective enrichment and enumeration of Listeria monocytogenes and other Listeria species in all food types, including milk and dairy products, and environmental samples. Listeria monocytogenes is the bacterium that causes the infection listeriosis which is an illness very important in food safety. The control of this bacterium is very important due to its ability to grow at temperatures as low as 3°C. Listeria is killed by cooking and pasteurization. It can be present in raw milk and foods made from raw milk as cheeses (particularly soft-ripened varieties) or ice cream. It can also live in food processing plants and contaminate a variety of processed meats. Soy peptone and tryptone provide nitrogen, vitamins, minerals and amino acids essential for growth. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Dextrose is the fermentable carbohydrate providing carbon and energy. Yeast extract is source of vitamins, particularly the B-group essential for bacterial growth. Potassium phosphates act as a buffer system. Nalidixic acid blocks the DNA replication of susceptible bacteria and acts against many Gram-negative bacteria. The Acriflavine and cicloheximide are the Gram-positive selective components.
