Less invasive sampling methods for PRRSV detection in swine: Dry blood spots, oral swabs, and tonsil oral scrubbing in intentionally exposed gilts

Tonsil oral scrubbing and dry blood spots are reliable and cost-effective alternatives for detecting the virus in recently inoculated gilts.

Proposing a clinical case definition for PRRSV outbreaks in sow herds based on key productivity indicators

A new clinical case definition for PRRSV outbreaks in swine breeding herds has been proposed using a system based on KPI signals that will trigger diagnostics.

Evaluation of an electrostatic precipitator in mitigating the transmission of airborne viruses in experimentally infected pigs

Under the conditions of this study, the electrostatic precipitators efficiently removed IAV aerosol particles and delayed the onset of IAV and PRRSV infections in the sentinel pigs.

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.

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.

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.

A cross-sectional assessment of PRRSV nucleic acid detection by RT-qPCR in serum, ear-vein blood swabs, nasal swabs, and oral swabs

Ear-vein blood swabs, nasal swabs, and oral swabs can be used as surveillance samples for detecting PRRSV RNA by RT-qPCR in weaning-age pigs.

Refining PRRSV-2 genetic classification based on global ORF5 sequences and investigation of their geographic distributions and temporal changes

This study refined PRRSV-2 ORF5-based phylogenetic classification and investigated the geographic distribution and temporal changes of PRRSV-2 at the lineage/sublineage levels.
