Using phytogenic products in swine nutrition
The immunomodulatory effect —particularly anti-inflammatory— of phytogenic products added to the diet seems to play a crucial role in addressing intestinal clinical pictures in pigs.

Risk factors associated to Oedema disease in pigs
OD will normally appear after 1 or 2 weeks post-weaning and most likely associated to the presence of other risk factors.
Effects of ceftiofur treatment on the susceptibility of commensal porcine E.coli
The present study shows that treatment of several animals in a stable with ceftiofur influences the resistance pattern of intestinal Escherichia coli of the treated as well as untreated animals housed in the same stable.
Post-weaning E. coli immunity
In practice, and to have active-acquired antibodies ready at weaning, piglets should be immunised 10 days to 2 weeks before weaning.
Emergence of plasmid-mediated colistin resistance mechanism
During a routine surveillance project on antimicrobial resistance in commensal Escherichia coli from food animals in China, a major increase of colistin resistance was observed.
Differential diagnosis of post-weaning diarrhoea in pigs
An accurate diagnosis is sometimes difficult because of the common occurrence of mixed infections, the compounding effects of environment and nutrition and the difficulties experienced in isolating and identifying all the possible pathogenic agents involved.
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.
