A modification of UVM11 Medium, Fraser Broth Half-Strength is a primary selective enrichment broth for the isolation of Listeria spp. from food and environmental samples and is generally used in conjunction with Fraser Broth (BM0640). Although the base is identical to Fraser Broth it differs in that it contains only half the quantity of selective agents (Nalidixic acid and Acriflavine).
