The main mechanism of defense against intracellular infections, particularly virus.

In most fattening herds, the biggest risk for the finisher pigs to become infected with Salmonella is the within-farm contamination cycle of Salmonella. The biggest risk for introduction of Salmonella is buying infected piglets.

This article shows the different measures taken and the strategy followed to eradicate PEDv in a commercial farm: stabilization, creation of a disinfection bubble, monitoring and verification.

It is difficult for a single additive to mimic the effect of the addition of antibiotics or ZnO. This is why we need to combine groups of additives in water and feed, so they act both, as prevention and treatment.

Recognition of the pathogen is the first step of defensive immune response; both innate and specific immunity have mechanism to recognize the pathogen.

These days, the sale of breeding sows or boars with mange is considered unacceptable.

The current diagnostic tests are very powerful, allowing us to detect even small changes in the genome of a virus, but what do they tell us?

We were called for clinical problems on weaners that appeared a few days after a feed transition in a farrow-to-finish farm: swelling of the eyelids and forehead, incoordination, dyspnea and sudden death.

Why has antimicrobial resistance become more important over the last few years? Which is the responsibility of animal production? Is it possible to transfer antimicrobial resistance from animals to humans and vice versa? Can meat contain resistance even without having antimicrobial residues?

A study was performed including 69 PRRS-positive sow herds with the aim of comparing the use of PRRSV MLV and quarantine facilities with the PRRSV status of replacement gilts at first insemination.

This article reviews major immune cells: Neutrophils, macrophages, natural killer, lymphocytes, dendritic cells, mast cells...

As the risk of HEV exposure appears to rise in the human population an opportunity for production and certification of HEV free meat products, especially pork, is emerging.

The decrease in PCV2a and PCV2b genotypes over time and the increase in PCV2d in 2012 may be due more to other, unknown, factors than to immunological selection resulting from PCV2a-based vaccination.

Several reasons explain the failure of the German Salmonella Monitoring Programme to result in a continuous reduction of the frequency of salmonella-carrying pigs sent to slaughter at a national level.

Oral fluids are practical, fast, easy, cost-effective and reliable methods for sampling pig populations, but it has not been easy or practical to obtain such samples from suckling piglets...

The complexity of ASF control means we need to make a group effort to prevent the disease from entering the EU and make sure we are prepared to fight the disease if it shows up.
