Today, we are sharing a recent publication from Dr. Vannucci lab in the Veterinary Diagnostic Laboratory at the University of Minnesota. This project evaluated the pig’s response to a co-infection with Lawsonia intracellularis and Brachyspira hyodysenteriae after receiving an ileitis vaccine. The full manuscript is available in open access on the journal website.

Quantifying the impact of vaccination on transmission and diversity of influenza A variants in pigs
Today we are sharing a recent publication from the Torremorell lab regarding the impact of vaccination on the diversity of influenza variants in pigs.
The full article is available on the Veterinary Microbiology website.

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
In today’s Science Page, we propose a summary of an article by Belgian researchers Jorian Fiers, Dominiek Maes, Ann-Brigitte Cay, Laurent Mostin, Anna Parys, and Marylène Tignon on the influence of maternally-derived antibodies on PRRSV infection.

New research led by researchers at the University of Minnesota College of Veterinary Medicine (CVM) reveals that farmworkers vaccinating and weaning 3-week-old piglets can indirectly and significantly contribute to the spread of the influenza A virus (IAV) on swine farms. This information can help pig producers target biosecurity measures more strategically, curbing swine flu transmission and enhancing swine production outcomes.

We hope all our US readers had a great Memorial Day weekend. Today, we are talking about farm practices and flu in farm workers. This recent publication from the Torremorell lab is available in open access on the Porcine Health Management journal website.
Take-away points
- Naïve piglets becoming infected with influenza before weaning participates in the endemic status of sow farms.
- Numerous interactions between piglets and farm workers happen pre-weaning (e.g. processing, vaccinations)
- Between 16% and 94% of the samples taken post-activity from farm workers’ hands and clothing were PCR positive for influenza.
- Activities during the peri-weaning period had almost 6 times higher risk of flu detection.
