Description About Fraser Broth Base:
Fraser Broth Base is used with ferric ammonium citrate for the selective enrichment of Listeria species in a laboratory setting. Fraser Broth Base is not intended for use in the diagnosis of disease or other conditions in humans.
Fraser Broth Base is based on the formulation of Fraser and Sperber. This medium is used in rapid detection of Listeria from food and environmental samples. Listeria spp. grow over a pH range of 5.0 – 9.6, and can survive in food products with pH levels outside these parameters. Identification of Listeria is based on successful isolation of the organism, biochemical characterization, and serological confirmation.
This product is for research use only and is not intended for any human treatment or diagnosis.
