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.

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.

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).

In Korea, it is common to vaccinate sows as a whole-herd mass vaccination program, where all sows are vaccinated quarterly with a type 2 PRRSV vaccine. Therefore, it is recommended to vaccinate breeding females quarterly with additional type 1 PRRSV vaccine to control type 1 PRRSV infection.

The estimated cost of PRRS for European pig producers is 1,5b € every year.

The article suggests measuring external risks in order to compare swine farms based on a numerical figure, and thus initiate corrective measures to improve and numerically verify the improvements achieved.

Type 1 PRRSV is highly prevalent in Korean swine herds and currently reproductive failure is more important consequence of infection with type 1 PRRSV, than is respiratory diseases in growing pigs.

This type of investment may not be crazy when it comes to protecting farms with high genetic value (others are dependent on) or insemination centres.

According to the present status and the experiences obtained during the previous one and a half year, Hungary will get free of PRRS by 2020.

Diagnosis in oral fluids is indicated for the control of replacements on arrival and after the adaptation process, and of the different production batches, especially risk subpopulations such as animals with a slow growth rate.

Flies are not usually seen as a real risk of infection between farms unless we're talking about very high-density areas. However, flies can travel long distances if captured when collecting carcasses.

Biosecurity measures for visitors should be implemented in all farms without exception, and hand washing with soap and subsequent disinfection should be compulsory in those farms where showering is not.

How can we tell whether a transport vehicle is clean by just taking a glimpse?
