Description

• Intended Use:
UVM Modified Listeria Enrichment Broth is used for the selective enrichment of Listeria spp.

• Product Summary and Explanation: Listeria spp. are ubiquitous in nature, being present in a wide range of unprocessed foods as
well as in soil, sewage, and river water. UVM Modified Listeria Enrichment Broth is a modification of the formula described by
Donnelly and Baigent. This formula is used for the selective enrichment of Listeria spp. from food and clinical specimens.
Listeria spp. grow over a pH range of 5.0 – 9.6, and survive in food products with pH levels outside these parameters. Listeria
spp. are microaerophilic, Gram-positive, asporogenous, non-encapsulated, non-branching, short, motile rods. Motility is
pronounced at 20°C. Identification of Listeria is based on successful isolation of the organism, biochemical characterization, and
serological confirmation.
