There are still unknown factors that prevent or block PRRSV replication in the endometrium and the not sufficient number of susceptible cells in the placenta might join forces and cause resistance to placental/transplacental PRRSV infection before 90 days of gestation.
The Porcine Reproductive and Respiratory Syndrome (PRRS) is an economically significant disease that affects the pig industry globally. This section reviews the latest new features on this disease.
Monitoring protocols in boar studs are often insufficient to timely detect an infection.
The first goal of the project is to control PRRSv-infections in order to produce negative offspring.
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.
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 disease and outcome following PRRS infection has significant inherited components.
Is the right strategy to get a farm stable, that is, control clinical signs reducing the economic impact of the disease; or should a farm adopt strategies to go “negative”? As for other questions in the epidemiological field, our answer is “it depends”.
