Long-term evolutionary dynamics of Porcine Epidemic Diarrhea Virus (PEDV) in the U.S. a decade after introduction

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.

Today’s Science Page University of Minnesota researchers Joao Paulo Herrera da Silva, Nakarin Pamornchainavakul, Mariana Kikuti, Xiaomei Yue, Cesar A. Corzo and Kimberly VanderWaal take a look at PEDV in the United States.

Tracing the evolutionary history of the novel PRRSV-2 L1C-1-4-4 variant

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 Friday we are looking at the PPRSv L1C-1-4-4 variant and comparing its evolution to other PRRSv strains, thanks to research by Nakarin Pamornchainavakul, Mariana Kikuti, Igor A. D. Paploski, Dennis N. Makau, Albert Rovira, Cesar A. Corzo, and Kimberly VanderWaal.

Type 2 PRRS virus ORF5 divergence from VR2332 over time

This week, Dr. Mariana Kikuti and the MSHMP team share the evolution of PRRS ORF 5 from the original strain discovered in the 90s.

Key Points

  • ORF5 sequencing for PRRSv monitoring have been increasing over time
  • ORF5 nucleotide divergence from the reference VR2332 averaged at around 10-15% throughout 2000-2018.
