Sodium Selenite Broth is a selective medium for the enrichment of Salmonella that may be present in small numbers and competing with intestinal flora. The broth medium can be made more selective for the isolation of Salmonella in meat products when it is incubated for 16 to 18 hours at 43°C instead of 37°C. The enrichment medium is frequently used for the detection of pathogens in fecal specimens as these pathogens usually represent a small proportion of the intestinal flora. Peptone mixture is a source of nitrogen, vitamins and amino acids essential for growth. Lactose is the fermentable carbohydrate providing carbon and energy. Sodium selenite inhibits Gram-positive bacteria and most enteric Gram-negative bacteria, except Salmonella. Sodium phosphate is a buffer.
