Aerosol Detection and Transmission of PRRSv: What Is the Evidence, and What Are the Knowledge Gaps?

Aerosol transmission of Porcine Reproductive and Respiratory Syndrome virus is a major issue hog producers have had to deal with for several decades now. It encouraged the development of air filtration systems in farrow-to-wean farms as well as the isolation of high-value genetic lines in remote areas. This new publication, a collaboration between Dr. Arruda at the Ohio State University and Drs. Corzo and Torremorell from the University of Minnesota is a review of our knowledge of how PRRS is transmitted via aerosol.

How investigating the piglet helps us advance influenza control

Before we start with today’s post, we would like to wish you all the best for this new year. Thank you for your support and for reading us year after year.
So here is to a new decade, always bringing you science-driven solutions!

Weaning-age piglets are responsible for the spread of many diseases, but in the case of influenza, they are also responsible for circulating the virus within the herd.

Effect of Single Dose of Antimicrobial Administration at Birth on Fecal Microbiota Development and Prevalence of Antimicrobial Resistance Genes in Piglets

It is the end of the year and to celebrate, here is one of the favorite Science Pages of the year, from Dr. Lowe’s team at the University of Illinois.

Keypoints

  • Early life antimicrobial prophylaxis had no effect on individual weight gain, or mortality but it was associated with minor shifts in the composition of fecal microbiota and noticeable changes in the abundance of selected Antimicrobial Resistant Genes
  • The shifts in fecal microbiota structure caused by perinatal antimicrobial intervention are modest and limited to particular groups of microbial taxa
  • Early life PPG and TUL intervention could promote the selection of Anrimicrobial Resistant Genes in herds

Happy holidays from the MSHMP team

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.

Happy Holidays!

Podcast: Conversations around African Swine Fever

Happy holidays everyone! The swine group at the University of Minnesota wishes you the most wonderful time, surrounded by friends and family.

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 latest episode of At the meeting… sees our hosts and their invited speaker talk about African Swine Fever: what is the current situation?
