Best of Leman 2021: Andreia Arruda – How many different PRRSV can be found in farms in a single sampling event and overtime?

This is our most popular series on the blog. 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.

You can find all of the presentations selected from previous conferences on the blog here.

This month we learn about PRRSV with Dr. Andreia Arruda (Ohio State University).

Are you a researcher who would like to present their research at the Leman Swine Conference? The Leman Swine Conference is accepting abstracts for the 2022 conference! Read about the requirements and submission process on the Leman Swine Website.

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.

What are PRRS lineages?

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.

Following up from last week’s article, Igor Paploski, Mariana Kikuti and Cesar Corzo dig into what PRRS linages are and give background on Lineage 1, and the sublineages that further classify the virus.

PRRS RFLP, what is it and how we use them?

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 University of Minnesota (Mariana Kikuti, Igor Paploski, Marcello Melini, and Cesar Corzo) explains RFLPs, how they are used today and some of their pitfalls.

Experimental pig study confirms the high virulence of the recently emerged PRRSV 1-4-4 L1C variant strain

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.

In today’s Science Page we learn about the findings of a study conducted by researchers at Iowa State University inoculating pigs with the 1-4-4 L1C variant.
