Research develops breakthrough technology to address PRRS
The discovery of PRRS-resistant pigs could significantly improve animal well-being and save hundreds of millions of dollars each year.

Stochastic model of PRRSV control strategies on a swine farm in the United States
After 24 years of experience we still don't have a control plan agreed upon and accepted by all our technical community. Why?
Measurement of time-to-virus-negative-piglets interval in PRRSv positive sow herds
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.
PRRS control and eradication plans in Europe
Only a few EU countries are discussing national eradication as a possibility.
Classifying swine herds by PRRSv status
The classification system for PRRSV status of herds is based upon a set of definitions reflecting the biology and ecology of PRRSV.
PRRSV pathology in the lungs
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.
Efficacy of combined vaccination against Mycoplasma hyopneumoniae and porcine reproductive and respiratory syndrome virus in dually infected pigs
In conclusion, combined vaccination against both Mhp and PRRSV efficiently pooled the efficacy of each single PRRSV and Mhp vaccination and could be an interesting tool to control PRDC in European swine production.
Boehringer Ingelheim Animal Health launches two new swine vaccines in Europe
New vaccines Ingelvac PRRSFLEX® EU for piglets and ReproCyc® PRRS EU for sows offer sustainable control of Porcine Reproductive and Respiratory Syndrome (PRRS).
Cambodia reported the presence of PRRS
The OIE has reported two outbreaks of PRRS in Cambodia, located in Chi Kraeng and Soutr Nikom (Siem Reap), with a total of 33,680 susceptible animals of which 2,661 cases and 997 deaths.
Challenges in diagnosis of PRRSV
Currently, no single RT-PCR assay could be recommended as a universal method allowing for detection of all PRRSV strains with optimal sensitivity.
Impact of an early exposure to SIV and PRRSv in post-weaning mortality
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).
Association of the presence of IAV and PRRSV in sow farms with post-weaning mortality
Our results suggest that infection with IAV or PRRSV in the pre-weaning period is associated with an increase in post-weaning mortality.
Control of reproductive PRRS outbreak by type 1 PRRS vaccine
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.
PRRS cost for the European swine industry
The estimated cost of PRRS for European pig producers is 1,5b € every year.
Evaluating the duration of a swine breeding herd PRRSV-free status and its relationship with measured risk
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.
European strains of PRRSV in Korea
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.
