BAX® REAL-TIME ESCHERICHIA COLI O157:H7 ASSAY
BAX System REAL-TIME PCR Assay for rapid detection of Escherichi coli 0157:H7
Escherichia coli O157:H7 is a recognized foodborne pathogen found in raw beef and more recently in produce. It can cause serious and sometimes fatal illness at a very low infectious dose (as few as 10 organisms). The organism can be difficult to detect with traditional culture methods, especially where low levels of the target must be isolated from high levels of competing background flora.
The BAX® System uses DNA-based technology to provide same-day results that are reliable and reproducible, allowing food producers and processors to quickly and accurately release safe products to the market.
BAX® Real-Time Escherichia coli O157:H7 Assay detects all known strains of E. coli O157:H7, including rough strains, providing highly accurate results. This reliable system was developed in collaboration with USDA ARS, using "real-world" samples; 375g beef trim; 65g ground beef; 25g spinach and lettuce. The test involved a simple, single-stage enrichment in MP media, followed the real-time PCR assay. Once set up, this takes only 55 minutes to reach a result, displayed in clear, easy-to-interpret plus/minus symbology. The whole process provides same-day results – as little as 10 hours for some matrices.
Ninety-six samples can be processed at a time.
