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.

This article will focus on clinical signs of some E coli infections: neonatal colibacillosis, post-weaning colibacillosis diarrhoea and oedema disease.

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.

The ideal sample for diagnostic of neonatal enteric pathogens is the submission of live piglets.

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.

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.

Seaweeds are rich in undigestible polysaccharides and are a potential source of soluble dietary fibers. The most abundant polysaccharides in brown seaweeds are laminarin, fucoidan and alginic acid.

This case starts with abortions that occur dramatically in April. They begin on Saturday the 23rd and during the following week continue until reaching 34 abortions.

UTIs are among the most frequent bacterial infections in the herd but they are rarely diagnosed or taken into consideration by veterinarians.
