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.

Effect of litter aggregation and pooling on detection of PRRSv in piglet processing fluids

The Science Page this week was written by the MSHMP team and covers pooling of processing fluids. A more detailed report can be found on the blog. Currently, a study to evaluate the number of negative processing fluids to declare a farm stable is ongoing. If you are interested in participating in this study, contact Dr. Juan Sanhueza (jsanhuez-at-umn-dot-edu).
