HALF FRASER BROTH BASE (ISO 11290-1:2017)

Listeria monocytogenes is a Gram-positive, non-spore forming, aerobic to facultatively anaerobic, rod shaped bacterium, which exhibits pathogenicity towards humans and other animals. Although not generally recognized as a food-borne pathogen, three recent outbreaks of listeriosis may indicate that this organism is becoming more prevalent as an agent of food-borne disease. Fraser Broth Base and Fraser Supplements are based on the formulation of Fraser and Sperber. Fraser supplements results in a higher detection rate of Listeria monocytogenes.
