Impact of the use of ß-lactam antimicrobials on the emergence of E. coli isolates resistant to cephalosporins

The results suggest that the use of ceftiofur and amoxicillin at different stages of the rearing cycle are independent risk factors for the selection of CR E. coli.

Usefulness of Real-Time PCR in the diagnosis of porcine colibacillosis

It allows us to analyse virulence factors directly on the clinical sample, avoiding the intermediate stages of culture and determinations on each of the selected isolates, leading to considerable savings in time and costs.

Diagnostics of Escherichia coli infections in swine: typing E. coli isolates

Hemolyzing E. coli are not the only ones that are pathogenic. Moreover, hemolyzing E. coli do not generally possess relevant fimbrial and toxin genes.

Escherichia coli infections in pigs (2 of 2)

Post-weaning colibacillosis and oedema disease are common global infection among farmed pigs – these strains of E coli appear to be "embedded" in most pig farms, so elimination is not a current option. Vaccination of sows or gilts with ETEC vaccines has no effect on post-weaning E. coli infections.
