Phenotypic and genotypic characteristics of DEPs
| DEP | Defining characteristic(s)a | Target(s) |
|---|---|---|
| tEPEC | Presence of both intimin (as a marker of the LEE) and the BFP contained in the EAF plasmid | eaeA, bfpA |
| aEPEC | Presence of intimin (as a marker of LEE); absence of the EAF plasmid and Shiga toxins 1 and 2 | eaeA |
| ETEC | Presence of ST or/and LT | lt, st |
| EIEC | Presence of the invasion-associated locus of the invasion plasmid | ial |
| STEC | Presence of Shiga toxin 1 and/or Shiga toxin 2; in addition, some strains also have intimin (as marker of LEE) | stx1, stx2, eaeA |
