PCR limitations in PRRS diagnostics
PCR can detect the virus in virtually any material but, does it mean the sample contains the virus and it is infectious? Is any PCR test valid for any strain?

PRRSV surveillance. How could we track the progress towards PRRS control in our farms?
How can we monitor our program? Which pigs should be sampled? How many? How often should we sequence the virus/es present in our farms?
Gilt acclimation to PRRS virus (2/2). Steps to meet the challenge
Four veterinarians talk about gilt acclimation: programs they put in place, how the immune status is measured and special management scenarios for introducing those gilts into the main herd.
Gilt acclimation to PRRS virus (1/2). Are there different approaches for different regions?
What is the preferred exposure method?, and the best status of the incoming gilts?, should they be raised on-farm or purchased?, … Veterinary practitioners from Germany, North America, China, and Spain share their opinions.
Are the nurseries becoming complicated? (1/3)
In recent years, pig production has been subject to several changes that have forced farmers to adapt. Some of these changes have a direct impact on the nursery.

The results of this study provide clinical information on how to reduce seminal shedding of type 1 PRRSV in boars using type 1 PRRSV-modified live vaccine.
Survival of viral pathogens in animal feed ingredients under transboundary shipping models
Results provide further evidence that contaminated feed ingredients may represent a risk for transport of pathogens at domestic and global levels.
Clinical case: Increase of returns: Management or PRRS?
Returns increase in a PRRS-positive farm in the middle of a census increase plus a change of management in the batch farrowing system, from 3 weeks to 1.
PRRSV sequencing and its use in practice
It is very important to analyze new PRRSV sequences against a broad reference set representing the farm, the system and the region, as well as the sequences of available commercial vaccines (this will make it possible to differentiate between field and vaccine strains).
