Vaccination decreases the risk of influenza A virus reassortment but not genetic variation in pigs

Today we are sharing a recent publication from the Torremorell lab in Microbiology and Infectious Disease regarding the impact of swine influenza A vaccination on the virus reassortment and on the genetic variation observable in pigs. The full article is available in open access on the journal’s website.

Harvesting Lessons Learned from HPAI Outbreaks in Poultry with Dr. Marie Culhane: A podcast

Dr. Marie Culhane is Professor at the University of Minnesota College of Veterinary Medicine who specializes in Influenza and emergency disease preparedness and management. The poultry industry has battled outbreaks of High Pathogenic Avian Influenza (HPAI) in recent years and as the old saying goes, “Your friends challenges are your cheapest learning opportunities”. We go in depth with Dr. Culhane on Influenza – what makes this a “shared disease” between humans, birds and pigs, what are the common control strategies employed across species and how can vaccine platforms help manage Influenza disease. We specifically focus on HPAI outbreaks and their analogies with reportable diseases in the swine industry. Poultry producers have had major HPAI outbreaks in 2015 and again now in 2022 – how have their biosecurity programs and diagnostic tools evolved over that period? How do they effectively implement control zones and permit requirements prior to movement? Ultimately, what have they done to improve the timeline from diagnosis to depopulation from 7 days to 36 hours from 2015 to 2022? Marie shares lessons learned about smallholder poultry operation management that correlates to similar smallholder swine operations as well as perspective about wild bird management akin to our challenges with feral swine management.

Evidence of influenza A infection and risk of transmission between pigs and farmworkers

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, University of Minnesota researchers Gustavo Lopez-Moreno, Peter Davies, My Yang, Marie Culhane, Cesar A. Corzo, Chong Li, Aaron Rendahl and Montserrat Torremorell present research on interspecies transmission of influenza A between pigs and farmworkers.

Evidence of influenza A infection and risk of transmission between pigs and farmworkers

Today, we share a recent study by the Torremorell’s lab published in open access, in the Zoonoses and Public Health journal this past month. Led by Dr. Gustavo Lopez, this work focuses on the interface between the pigs and farmworkers when considering influenza A infection.

Newly funded: University of Minnesota researchers secure $500K USDA grant to study novel pig influenzas

March 28, 2022

A team of researchers at the University of Minnesota has secured $500,000 to study how new influenza virus strains emerge, persist, and spread in pig populations—and what age, well-being, farm-production type, and epidemiological factors might help predict whether a new virus strain emerges.
