Product Code: LAB164
Developed as a modification of UVM II medium, Fraser broth is a secondary enrichment broth for the isolation of Listeria spp., and is similar to Palcam broth in that it contains aesculin to indicate the presence of a potential Listeria isolate.
It also contains lithium chloride in an attempt to suppress the growth of enterococci in the medium (as does Palcam). Fraser broth may also be used as a primary enrichment
medium by incorporating 1/2 strength supplement into the broth base
