PRRS regional control in Europe: the Dutch project is one year on the road!
The first goal of the project is to control PRRSv-infections in order to produce negative offspring.

Switzerland: a new PRRS outbreak detected
Last 25th March the virus was detected in 15 animals on a farm with fattening pigs that had had contact with the infected farm in Lucerne.
In vitro and ex vivo analyses of co-infections with SIV and PRRSv
This study is the first to show an impact of PRRSV/SIV co-infection and superinfections in the cellular and tissue immune response at the molecular level.
USA: 2013-2014 PRRS epidemic season continues to be surprisingly different
We have observed significantly fewer cumulative new breaks thru December.
United Kingdom: 2013 pig abattoir study
A total of 645 pig carcases were randomly selected and sampled at fourteen slaughterhouses between January and May 2013.
Recombination of PRRS viruses may produce mosaic isolates
Analysis of ORF5 and full-length genome sequences of PRRSV isolates of genotypes 1 and 2 retrieved worldwide provides evidences supporting that recombination is a common phenomenon and may produce mosaic isolates.
Switzerland: the detected PRRSV is US-type
According to data published by the Swiss Food and Veterinary Safety Federal Office (OSAV), the virus detected on the pig farm in Lucerne belongs to the US-type.
Switzerland confirms PRRS subclinical infection
The farm has a total of 213 animals, of which 13 cases.
Transmission of swine pathogens: a practical perspective
Pathogens that are transmitted mostly through direct, pig to pig, contact are generally contained with today’s biosecurity programs and pig flow strategies. However, pathogens using multiple routes of transmission seem to evade standard biosecurity programs.
Spain: the new platform ConPRRS has been launched
The Centre de Recerca en Sanitat Animal (CReSA), the Universidad Complutense de Madrid (UCM) and the Universitat de Lleida (UdL) have created a technical group for supporting the PRRS control (ConPRRS).
Transmission, biosecurity, and area regional control/elimination of PRRSV
A risk of airborne transmission of PRRSV is real, and air filtration can significantly reduce its risk. Area regional approach on PRRSV control/elimination indicates our direction where we should move forward in future.
PRRSv stability in manure and implications for transport biosecurity
About 50% of the vehicles used for transporting pigs in the United States are not washed between loads, so this article evaluates the ability of heating treatments to inactivate PRRSv present in manure-contaminated environments.
Clinical case: Effects of the adaptation to the welfare law in a PRRS outbreak
This farm produces its own gilts from grandmother sows, but taking advantage of the adaptation to meet the needs of the welfare law it was decided to increase its capacity from 600 sows to 1,200.
The role of host genetics in the response of pigs to PRRSV infection
Clinical disease and outcome following PRRS infection has significant inherited components.
Impact of PRRS vaccination timing in pigs with different maternal immunity levels
The main objective of this study was to further investigate this issue and determine if vaccination of older pigs would induce an earlier viremia and seroconversion.
Comparison of the virulence of European and North American genotypes of porcine reproductive and respiratory syndrome virus in experimentally infected pigs
This study demonstrates that type 2 PRRSV is more virulent than type 1 PRRSV in this experimental setting.
