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.

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.
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.
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.
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.
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.
Detection of enteric pathogens in newborn piglets (1/2)
The ideal sample for diagnostic of neonatal enteric pathogens is the submission of live piglets.
Clinical case: Episode with a high mortality in the weaning stage
The nervous system symptomatology is characterized by some cases of meningitis and opistothonus, dizziness and serious deep depression in a great number of animals. The necropsy shows, in all the cases, a serious lung congestion and an enteritis with a variable seriousness with a more or less important involvement of the mesenteric lymph nodes.
Clinical case: Post-weaning diarrhoea outbreaks in Eastern Europe
The pig farm management team in charge of the post-weaned piglet nursery areas on these wean-to-finish sites has found serious problems with diarrhoea in recent batches of piglets arriving from the breeding farms.
