Average time sites stay in a naïve PRRSV status: Preliminary Results

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.

Key points

  • Up to February 2021, 209 breeding herd moved to a PRRS naïve status a total of 259 times.
  • On average, sites remained naïve approximately two years before changing to a different status.
  • Most naïve sites moved to an active PRRSV break status in an average one and a half years.

ASF returns to the Caribbean: a podcast

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

African Swine Fever (ASF) returns to the Caribbean is the focus of this episode. After nearly 50 years, African Swine Fever (ASF) has returned to threaten the Caribbean swine population, including Puerto Rico. What are the risks for producers?

Phylogenetic Structure and Sequential Dominance of Sub-Lineages of PRRSV Type-2 Lineage 1 in the United States

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.

Keypoints

  • Lineage 1 PRRSv, the most prevalent PRRSV lineage in the U.S, can be sub-divided into eight sub-lineages
  • We documented the cyclic emergence and turnover of different lineages and sub-lineages (about every 3 years) based on both sequence count data and estimated past viral population sizes inferred from genetic diversity through time.
  • The eight sub-lineages differed in key GP5 amino acid sites that are thought to be involved in the immune response to the virus.
