Determining farm surface porcine reproductive and respiratory syndrome virus (PRRSV) contamination through viability RT-qPCR

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 this week’s Science Page we take a look at a study by Claudio Marcello Melini, Amanda Palowski, Declan C. Schroeder, and Cesar A. Corzo evaluating PRRSV viability on various surfaces found in growing sites.

Drs. Mariana Kikuti and Megan Nickel discuss “Less Invasive Sampling Methods for PRRSV Detection in Swine: Dry Blood Spots, Oral Swabs, and Tonsil Oral Scrubbing in Intentionally Exposed Gilts”

The Swine Disease Eradication Center is proud to present another episode of “Processing the Litter-ature”: a podcast in which peer-reviewed papers are docked, clipped and supplemented with a field perspective.

Drs. Mariana Kikuti and Megan Nickel discuss “Less Invasive Sampling Methods for PRRSV Detection in Swine: Dry Blood Spots, Oral Swabs, and Tonsil Oral Scrubbing in Intentionally Exposed Gilts” with guest host Mark Schwartz.
