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.

Transmission of a live influenza A virus vaccine in commercial pre-weaned pigs

The Plos One journal just published a new study by Dr. Gustavo Lopez and the Torremorell lab. The objectives of the project were to  1)assess the onset and duration of live attenuated influenza vaccine shedding in vaccinated pre-weaned pigs, 2)investigate the transmission of the live attenuated influenza vaccine from vaccinated to non-vaccinated pigs under field conditions and 3)evaluate whether the live attenuated influenza vaccine could be aerosolized and detected in the environment.
