Here we will focus the discussion on the practical applications and on lessons learned from recent field studies on response strategies for PRRSV management in affected breeding herds.

The gut-lung axis: New tools for improving the control of PRRS virulence and persistence at farm level.

The collection of tongues from stillborn piglets as a system to monitor the stability at farrowing serves to improve PRRS virus detection.

Consider these factors when deciding to eliminate or control PRRSv.

The goal is set in Danish pig production - By 2025, 75% of all finishers will be PRRS seronegative at slaughter. This will be achieved by a close corporation between veterinary authorities, the pig industry, slaughter companies, veterinarians and producers.

The Hungarian PRRS eradication program is based on a territorial approach as it is the only approach by which the infection or reinfection of PRRSV-free pig herds can be avoided with high probability.

With more herds breaking with highly virulent PRRS strains, what can we do to prevent and control infection? How does the 1-4-4 L1C strain differ?

Regional control programs were designed for the control and eradication of different viral diseases. Why are there only a few regional control programs still active for swine worldwide?

This PRRSV strain is affecting the U.S. Understanding where these viruses come from can help us stop this cycle.

Do we know what percent of imported batches of pigs are viremic for PRRS and to which strains?

What samples should be taken for the new PRRS categories according to the American Association of Swine Veterinarians (AASV) guidelines?

An outbreak of edema disease was treated with fasting and antibiotic therapy, but in subsequent batches these measures were no longer successful. The outbreak progresses and it was observed that when animals are medicated, either orally or parenterally, mortality increases both in number and speed.

We review what's new in the American Association of Swine Veterinarians (AASV) guidelines, which include new monitoring techniques and expanded and modified categories.

High virulence PRRS virus strains cause more accentuated clinical symptoms, higher mortality, higher viral load and dissemination in body tissues, as well as a higher inflammatory response.

In this article we summarize further discussions that we had with Dr. Nauwynck about his research findings on PRRS virus-host evolution.

What factors cause increased mortality and slow-growing piglets in the nursery phase? How can we address these issues?
