Diseases associated with E. coli

In swine, diseases associated with pathogenic Escherichia coli (E. coli) mainly affect piglets in the neonatal and post-weaning periods.

In newborn piglets, the E. coli involved are essentially enterotoxin-producing strains (STa, STb, and/or LT) and possessing colonization factors (particularly F4, F5, and/or F6). These E. coli are called enterotoxigenic E. coli, or ETEC.

In weaners, the strains involved are either:

  • ETEC with F4 and/or F18 colonization factors.
  • E. coli producing the toxin STx2e (shiga-like toxin producing E. coli, or STEC) and possessing the colonization factor F18. These latter strains are responsible for edema disease.
  • E. coli producing both one or more enterotoxins and the STx2e toxin and possessing the F4 and/or F18 colonization factors. These strains cause both diarrhea and edema disease.

For researching and characterization of these E. coli, the tests to be requested are:

  • Neonatal period: E. coli F4, F5, F6, STa, STb, LT qPCR
  • Post-weaning period: E. coli F4, F18, STa, STb, LT, STx2e qPCR

Biovet will issue the test results within 4 to 5 business days (one more day for antibiotic sensitivity testing (antibiogram))

These tests are carried out from Monday to Friday, except for the antibiogram, which is produced 7 days a week.
