Escherichia coli is part of the normal flora but some diarrheagenic strains causing severe disease. Transmission to humans is primarily foodborne. Pathogenic strains are characterized by their toxins.
The enterohaemorrhagic E. coli (EHEC) produce the Attaching and Effacing protein (Eae) and the Shiga-like toxins stx1 and/or stx2 which are closely related to toxins from Shigella dysenteriae.
1 Vial yellow cap 96 reactions Stx1 (lyophilized)
1 Vial black cap Positive Control (32,000 copies, lyophilized)
Additional Reagents required
LightCycler® Multiplex DNA Master
or LightCycler® 480 Probes Master
A 87 bp long fragment from the stx1 gene from enterohemorrhagic E.coli is amplified with specific primers and detected with a FAM labeled hydrolysis probe.
This assay detects 10 genome equivalent copies or less per reaction (plasmid DNA dilution).
Sample Material and Extraction
Typical samples are from feces, rectal swabs or bacterial culture. See ModularDx Extraction Protocols.
