After 24 years of experience we still don't have a control plan agreed upon and accepted by all our technical community. Why?

A gilt who has compromised limb health on entry to the breeding herd is more vulnerable to early removal as a result of lameness and more vulnerable to the negative production affects associated with it.

The transmission of PEDV through the feed supply chain is an example of a complex disease transmission pathway that triggered swine feed industry stakeholders to collaborate in understanding and addressing the risk factors.

The accuracy and security provided by the combination of samples of weaned pigs and piglets at birth, either stillborn or live piglets, help us make a decision that will be crucial in any eradication plan.

Only a few EU countries are discussing national eradication as a possibility.

An erythema multiforme (EM) was noticed in the majority (90%) of breeding stock, associated with respiratory problems and without mortality.

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.

I truly believe some strains of this bacterium are pathogenic for piglets and can cause diarrhea and reduced growth rate; however, we do not know yet how to identify them!

The classification system for PRRSV status of herds is based upon a set of definitions reflecting the biology and ecology of PRRSV.

The tissue damage is the consequence of direct apoptosis (and necrosis) of alveolar macrophage and their neighboring cells due to the release of apoptotigenic cytokines, reactive oxygen species, and nitric oxide.

The rate and sequence of mucosal immune maturity from birth to an ‘adult-type’ pig is an important determinant of subsequent performance, health and survival, and hence impacts on the efficiency and profitability of pork production.

Senecavirus A (SVA) has been suggested as a causative agent of idiopathic vesicular disease in pigs. Additionally, a neonatal losses syndrome, affecting piglets of 0-7 days of age, associated with SVA has recently been reported.

A series of unsuccessful measures are taken until the problem is finally solved.

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.

Currently, no single RT-PCR assay could be recommended as a universal method allowing for detection of all PRRSV strains with optimal sensitivity.

Infection with swine influenza virus and porcine reproductive and respiratory syndrome during the suckling period was associated with an increase in post-weaning mortality (more limited in the case of SIV and of larger magnitude for PRRSV).
