Assessment of changes in antibiotic use in grow-finish pigs after the introduction of PRRSV in a naïve farrow-to-finish system
The PRRSV outbreak in the source was associated with a grow-finish antibiotic usage increase.

ProtonDx's Dragonfly wins 2025 Tesco Agri T-Jam, offering a rapid new way to fight PRRSV and swine flu
The Dragonfly diagnostics platform wins the prestigious award for its rapid, on-site pathogen detection, enabling swine producers to proactively manage swine herd health, cut antibiotic use, and optimise their supply chains.
333 Emerging Voices - Long-distance airborne transmission of PRRSV: a systematic review
This work presents a systematic review of the available scientific literature on the long-distance airborne transmission of PRRSV. Final thesis at the College of Veterinary Medicine, UAB, Spain, advised by Enric Mateu.
Boosting immunity against viral challenges
Boosting key performance indicators in swine production requires addressing viral pathogens, which remain a major challenge for swine health, performance, and farm profitability. Emerging strains, such as H1N2#E and devastating diseases like ASF, highlight the urgency for innovative control strategies. C12 monoglycerides represent a promising approach to enhance pigs’ immune defenses and mitigate viral impact.
Health restart: the power of depopulation and repopulation to restore profitability
When losses and costs from poor health threaten the current and future farm profitability, perhaps a “clean slate” should be considered.
Explaining the persistence of PRRSV in vaccinated breeding herds
Selection of viral variants with enhanced transmission and reduced neutralization susceptibility alongside lateral introductions may explain the persistence of PRRSV in vaccinated breeding herds.
UK: PRRS project funding to improve biosecurity in Scotland
A project to eradicate PRRS from Scotland to get further Scottish Government funding.
U.S: Launch of new monthly PRRSV variant report
A new national surveillance effort enhances decision-making in swine health by identifying and communicating emerging PRRSV variants.
Denmark: Analysis on PRRS and antibiotic consumption in 2024
There was a highly significant effect of PRRS health status on the median antibiotic consumption at the herd level.
Environmental enrichment affects immunity and reduces disease severity in pigs after co-infection, with stronger effects when applied from birth than from weaning
Enriched housing from birth reduced disease severity to co-infection with PRRSV and A. pleuropneumoniae.
South Africa’s Pork Industry Faces Threat from US Trade Choice
South Africa risks its pork industry to protect citrus exports as US trade demands market access for pork despite PRRS disease concerns.
The implications of the PRRSV recombination dilemma
PRRS control measures also reduce the opportunities for different wild-type viruses to recombine and create more aggressive strains.
PRRS Molecular diagnostics: when sequencing only 4% is not enough
Genetic mutation and evolution of PRRSV can occur across all genes. Unlike ORF5, which only represents about 4% of the PRRSV genome, NGS can recover a whole PRRSV genome to be used in epidemiological investigations.
Comparison of a novel rapid sampling method to serum and tonsil scraping to detect PRRSV in acutely infected sows
Results suggest great potential of tonsil-oral scraping as a novel, practical, and rapid tool for PRRSV RNA detection in sows to assess sow herd status.
PIC receives FDA approval for technology used to breed PRRS-resistant pigs
PIC is among the first to receive approval for the use of gene editing in commercial livestock in the U.S.
From 32% to 68% of PRRS negative farms after 3 years of the Danish national PRRS reduction strategy
The first three years of the Danish PRRS reduction strategy have shown that it is possible to control and reduce the prevalence of PRRS in Danish pig production.
