PRRSv ORF5 difference from VR2332 by herd type

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, the MSHMP team assessed differences in ORF5 sequences compared to VR2332 based on the type of farm, the sequence was collected at.

Key points

  • Breeding herd sequences differ 8%-16% while in other herd types they differ 1%-15% from VR2332 at the ORF5 level. 
  • The larger nucleotide identity (%) range compared to VR2332 in growing pigs suggests a higher viral diversity within this group.

Focusing on the grow/finish stages of production to better control PRRS, the new challenge of the swine industry?

Should we redirect our research efforts to focus on PRRS prevention and control in growing and finishing pigs? This was the call for action made by Dr. Montse Torremorell, Associate Professor at the University of Minnesota when she opened the special session “Grow/finish phase of production: What are we learning and implications for making progress on PRRS control.” sponsored by Boehringer Ingelheim during the North American PRRS Symposium this past weekend in Chicago. Torremorell argued that if the swine industry wants to advance regional PRRS control, more emphasis needs to put on preventing and controlling PRRS in growing pigs.

Best of Leman 2018 series #3: J.Angulo – Understanding PRRSV infection dynamics in growing pigs in control and elimination programs

We launched a new series on the blog last year. Once a month, we are sharing with you a presentation given at the Allen D. Leman swine conference, on topics that the swine group found interesting, innovative or that lead to great discussions.

We can find all of the presentations selected from last year’s conference on the blog here.

Our third presentation for this year is from Dr. Jose Angulo from Zoetis and Dr. Paul Yeske from Swine Vet Center regarding PRRS infection dynamics in growing pigs.
