DEC PCR Kit
The DEC PCR Kit is a multiplex PCR system that detects virulence genes from diarrhoeagenic E. coli 1 (DEC). Traditionally, this has been achieved by serotyping, followed by verocytotoxin cell assays, and therefore strains have previously been overlooked where they have virulence genes that have not had a serotype known for its pathogenicity. The DEC Primer Kit therefore makes it possible to identify more precisely pathogenic E. coli strains. The kit contains a primer mix that consists of 8 primer pairs aimed at the following genes: intimin (eae), verocytotoxin 1 and 2 (vtx1 and vtx2, also called stx1 and stx2), heat-stable enterotoxin, human variant (estA–human) and porcine variant (estA–porcine), heat-stable enterotoxin (eltA), invasive plasmid antigen (ipaH) and 16S rDNA (functions as an internal positive control).
The most important groups of diarrhoeagenic E. coli strains and the genes used to determine them are set out below:
- Verocytotoxin-producing strains (VTEC) – identification: demonstration of vtx1 and vtx2.
- “Attaching and effacing” E. coli (A/EEC) including enteropathogen E. coli(EPEC) – identification: demonstration of eae.
- Enterotoxigenic E. coli (ETEC) – identification: demonstration of eltA, estA–human, or estA–porcine.
- Enteroinvasive E. coli (EIEC) – identification: demonstration of ipaH.
The DEC PCR Kit therefore allows identification of all of these groups.
