Fraser BrothPlus - improving Listeria isolation
Fraser BrothPlus and Half Fraser BrothPlus are recently-introduced variants of Lab M's standard Fraser Broth medium for the isolation of Listeria species
With Lab M's new half Fraser BrothPlus and Fraser BrothPlus, the antibiotic supplement is blended into the base medium, but the ferric ammonium citrate (FAC) component is supplied separately as a supplement.
By separating the FAC from the base medium, it can be omitted for improved Elisa performance, or included for compliance with the ISO 11290 standard.
Fraser Broth is traditionally used as a secondary enrichment medium for the isolation of all Listeria species.
With the incorporation of half strength supplement, it can also be used as a primary resuscitation or enrichment medium.
