Investigating PEDv Infections and Lessons to Improve Biosecurity in Finishing Pigs

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, we are reporting a collaborative work between the MSHMP team and Dr. Donna Drebes from Seaboard Foods regarding PEDv infections in finishing sites and its impact on biosecurity.

Natural transmission and detection of Mycoplasma hyopneumoniae in a naïve gilt population

Dr. Alyssa Betlach, member of the Maria Pieters Myco Lab, recently published a study on the natural transmission of Mycoplasma hyopneumoniae in Veterinary Microbiology. The study evaluated transmission rate in a naïve gilt population and compared various sample types to detect infection.

Understanding PRRSv diversity at the pig and litter level

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, Dr. Mariana Kikuti from the MSHMP team is sharing results from a study using whole genome sequencing to assess PRRSv diversity within and across litters.

Key points

  • Viral diversity within the piglet population is generally small, but higher diversity was found in ORFs 4 and 5a.
  • Within animal consensus changes were observed in a period as short as 2 weeks, which means piglets might be going to the GF sites with different viruses than the ones identified closer to farrowing.
