Post-epidemic dynamics of PEDV in the United States: Current trends and patterns

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.

This week, the MSHMP team is sharing what they are observing regarding Porcine Epidemic Diarrhea virus in the US. What are the trends and patterns emerging years after the epidemic?

Main Points

Since July 2014, the number of PEDV yearly outbreaks reduced both numerically and in geographical distribution.
PEDV outbreaks occur seasonally, with most cases being detected during winter.
Spatial-temporal clusters of PEDV outbreaks were detected, most of which occurred prior to 2019.

Porcine epidemic diarrhea (PED) is a swine enteric viral disease first documented in the U.S. swine population in 2013, at which time it sparked a major epidemic. Since then, PEDV has persisted in the U.S. breeding herd with low incidence during the post-epidemic period. Despite continued monitoring and surveillance, there is minimal research and understanding of the endemic phase of PEDV in the country. Our objective was to characterize PEDV in the U.S. breeding herd in the post epidemic period (spatial-temporal distribution of cases and associated factors).

Keeping PRRS 144 Out of Sow Herds: a podcast

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

The emergence of PRRS 144 has increased the risks of breaks in sow herds.

Dr. Karyn Havas (Pipestone Research) and Dr. Mariana Kikuti (University of Minnesota) join The ATM team (Dr. Montserrat Torremorell – College of Veterinary Medicine, University of Minnesota, Dr. Gordon Spronk – Pipestone Veterinary Services, and Dr. Tom Wetzell – Swine Veterinary Consultant) to identify what producers can do to reduce the threat.

Listen to the episode (~25 minutes)

Pooling udder skin wipes to detect influenza in preweaning pigs

This is a recent publication from the Torremorell’s lab refining the use of udder wipes to detect influenza in preweaning pigs. It is available in the Journal of Veterinary Diagnostic Investigation.

Key points

Pooling of three, five, and ten udder wipes was evaluated.
Sensitivity decreased if the Ct count was above 31.5.
Pooling more than three udder wipes can affect the ability to detect influenza virus.

Assessing Senecavirus A shedding and transmission in growing pig populations

This week, Drs. Preis and Corzo invite you to participate in a research project on Senecavirus A, sponsored by the American Association of Swine Veterinarians!

Enhanced Passive Surveillance for ASF and CSF

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.

This week, the Center for Animal Health and Food Safety at the University of Minnesota shares preliminary results regarding a project looking at enhanced surveillance for two Foreign Animal Diseases: African Swine Fever and Classical Swine Fever.
