Which wipes are better to detect flu: udder skin or nasal wipes?

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. Albert Canturri from the Torremorell lab is sharing results on a study looking at udder skin wipes and piglet nasal wipe to detect swine influenza.

Key points

  • Various wipe types can be used to sample IAV from the udder skin of lactating sows. Although differences between wipe types were not seen, wipes that were wet provided a better detection rate than dry wipes. 
  • Furthermore, wiping the nose of 5 piglets within a litter resulted in higher litter detection rates than sampling the udder directly. This indicates that within litter prevalence is a driver for IAV detection using wipes. 
  • Future steps are needed to assess differences in virus isolation among sampling procedures.

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.

Comparison of individual, group and environmental sampling strategies to conduct influenza surveillance in pigs

In this new scientific publication from Dr. Jorge Garrido, PhD candidate from the Torremorell lab, numerous sampling strategies to monitor influenza were compared. the following individual, litter, and environmental samples were included in the study:

  • Nasal swabs
  • Nasal wipes
  • Oropharyngeal swabs
  • Oral fluids
  • Surface wipes
  • Udder wipes
  • Airborne particle deposition
  • Air
