Fraser Broth (7626)
Intended Use:
Fraser Broth is expertly formulated for use with Acriflavin, Nalidixic Acid, and Ferric Ammonium Citrate, facilitating the selective enrichment of Listeria spp. This specialized medium is essential for microbiological applications, particularly in food safety testing.
Product Summary and Explanation:
First identified in 1926 by Murray, Webb, and Swann, Listeria monocytogenes presents a significant health concern within public health and food industries. This pathogen is notorious for its ability to cause severe illness, particularly affecting immunocompromised individuals and pregnant women. Epidemiological studies of listeriosis outbreaks reveal that contaminated foodstuffs are the principal transmission route, with common sources including turkey frankfurters, coleslaw, pasteurized milk, Mexican-style cheese, and pate.
Fraser Broth is based on a proven formula developed by Fraser and Sperber, designed for the rapid detection of Listeria from food and environmental samples. The medium accommodates the growth of Listeria spp. across a pH range of 5.0 to 9.6, ensuring effective recovery from various food products where conditions may vary outside these parameters. Listeria spp. are characterized as microaerophilic, Gram-positive, asporogenous, non-encapsulated, non-branching, short, motile rods, with motility being notably active at 20°C.
Identification of Listeria spp. is achieved through the successful isolation of the organism, utilizing biochemical characterization techniques followed by serological confirmation. This makes Fraser Broth essential for accurate microbiological testing and food safety protocols.
