Subclinical prevalence of enterotoxigenic Escherichia coli
This study investigated the prevalence of ETEC positive pigs in farms without clinical signs of diarrhea, and the antibiotic resistance pattern observed amongst ETEC strains isolates.

Clinical case: Control measures in an outbreak of oedema disease
A series of unsuccessful measures are taken until the problem is finally solved.
Colibacillosis management
If we back away from the specifics of E. coli and consider the big picture of infectious disease we can gain some broader insights on control methods.
Post-weaning E.coli enterotoxaemia: nutrition as a predisposing factor
Interactions between nutritional strategies and prevalence / severity of GI clinical pictures caused by E. coli after weaning.
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.
Low dietary protein decreases ETEC proliferation and attachment in the intestinal mucosa
Low-protein diets with balances amino acid profile decrease ETEC colonization in jejunal mucosa.
Oedema Disease case study
At autopsy of some affected pigs, the soft gelatinous oedema was evident in the eyelids, but also in the meso-colonic area of the spiral colon.
Clinical case: Edema disease on fattening pigs (70-80 kg)
We concluded an Edema disease episode, which is extremely unusual at this age.
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.
New Section on E. coli
We are pleased to introduce a new Section, Colibacilosis. Escherichia coli is the cause of several diseases in pigs, including diarrhoea and oedema disease in piglets, which have a major economic impact.
Effects of ambient temperature on energy and nitrogen utilization in lipopolysaccharide-challenged growing pigs
In conclusion, our study confirms that high temperature reduces feed intake, growth performance, and HP.
Escherichia coli infections in pigs (1 of 2)
This article will focus on clinical signs of some E coli infections: neonatal colibacillosis, post-weaning colibacillosis diarrhoea and oedema disease.
New ZnO presentations can be used at lower concentrations in weanling diets
Low concentrations of commercial potentiated ZnO is effective in against of ETEC-challenged weaning pigs.
Detection of enteric pathogens in newborn piglets (2/2)
The main aspect that cannot be forgotten is the complete approach necessary to evaluate all possibilities. In that sense, samples have to be collected and tested to all possible agents that might cause diarrhea.
