A Modified Method for the Selective Enrichment of Listeria
A Modified Method for the Selective Enrichment of Listeria
26 Nov 2015This application note demonstrates the use of a modified UVM-Listeria Selective Enrichment Broth for the selective enrichment of Listeria according to USDA-FSIS guidelines. The combination of various peptones, extracts, salts, and buffer substances enable very good growth of Listeria. The selectivity is due to the antiproliferative substances nalidixic acid and acriflavine hydrochloride. The two-stage enrichment method has demonstrated its value especially with sample materials (meat and meat products) that are characterized by a high level of accompanying flora.

MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.
