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.

Comparison of samplers collecting airborne influenza viruses: 1. Primarily impingers and cyclones

Researchers from the University of Minnesota School of Public Health and College of Veterinary Medicine are publishing a series of articles in PLOS ONE comparing the various air samplers used to detect airborne viruses such as influenza. This first publication, available in open access, focuses on impingers and cyclones.

Highlights

  • Higher quantities of virus were recovered by high flow rate samplers
  • Lower flow rate samplers performed better when virus concentrations were high
  • Based on the question of interest, a different air sampler might be more efficient.

Impact of nurse sows on influenza A virus transmission

A study by the Torremorell group was recently published in the Preventive Veterinary Medicine Journal. In this publication, Dr. Jorge Garrido-Mantilla et al. evaluated if piglets put together with a nurse sow were more likely to be influenza A positive and conversely, if a nurse sow could become infected when adopting a litter of positive piglets.
