Updated epidemiological curve of cases associated with the new PRRS Lineage 1C RFLP1-4-4 variant

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.

As the MSHMP team continues to monitor the detection of the newly described PRRSv Lineage 1C RFLP 1-4-4 variant, they are updating the epidemiological curve of cases associated with this variant.

Conferencia Porcina Allen D. Leman en español – Spanish Leman conference

Cada año cientos de participantes de más de 20 países, incluyendo a veterinarios y profesionales vinculados a la salud, producción y administración porcina, acuden a la conferencia de la Leman. La mezcla entre ciencia básica, aplicada y experiencias de campo, les permite a los miembros de la industria porcina mantenerse actualizados con información de último nivel para que sea usada e implementada en sus sistemas de producción.

Dada la situación de COVID-19 a nivel mundial, la dificultad de viajar internacionalmente y al éxito que la conferencia de la Leman tuvo en 2020 ofreciendo charlas traducidas al español, el comité organizador decidió acercarse a la audiencia de habla hispana y realizar una conferencia virtual solamente en español este año.

Esta edición en español contará con presentaciones de temas actuales aplicables a los profesionales líderes del sector porcino, formato virtual e interactivo, acceso a las grabaciones de las presentaciones hasta marzo de 2022 y presentaciones de posters que se aceptarán en PDF hasta el 15 de noviembre, al respecto, un panel con líderes de la industria porcina resumirá los mensajes más destacados de estos.

Como siempre la misión continúa siendo la de contribuir al desarrollo, crecimiento y capacitación de todos los individuos que participan en la industria

Esperamos contar con su presencia en la primera conferencia de la Leman en español.

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.
