E.coli Pathogen Detection: Atlas® E.coli O157:H7 EG2 Detection Assay
A rapid, accurate, and reliable molecular test for E. coli O157:H7 detection from food samples.
The Atlas® E. coli O157:H7 EG2 Detection Assay is the first AOAC-approved assay to test for the presence of Escherichia coli (E. coli) O157:H7—the E. coli strain most commonly associated with foodborne illness—in beef and produce samples. E. coli O157:H7 belongs to a serogroup of E. coli organisms known as Shiga toxin-producing E. coli (STEC), the most severe form of E. coli. The U.S. Centers for Disease Control and Prevention (CDC) estimates that there are approximately 265,000 STEC-related infections annually in the United States. More than one-third (36%) of these infections are believed to be related to O157 STEC, the most widely reported STEC to cause human illness, accounting for 96,000 foodborne illnesses annually.
The Atlas E. coli O157:H7 EG2 Detection Assay is designed for the Atlas System, a fully automated molecular pathogen detection system. When used in conjunction with the Atlas System, the Atlas E. coli O157:H7 and STEC Detection Assays offer a complete platform solution for even the most rigorous food safety programs. The Atlas solution provides true “walk-away” automation with unparalleled gains in standardization and lab efficiencies, guaranteeing high-quality results and the ultimate in peace of mind.
As with other Atlas Detection Assays, the Atlas E. coli O157:H7 EG2 Detection Assay has an easy 3-step process that generates accurate results faster:
- Enrich—a single enrichment step with commercially available media allows for streamlined media preparation
- Transfer—an aliquot of the enrichment is transferred to a Roka G2 Sample Transfer Tube, with no requirement for heating, centrifugation, or sample purification
- Automate—place the Roka G2 Transfer Tube directly on the Atlas System and walk away! Final results are available in 3.5 hours
