PRRS – Swine in Minnesota

Phylogenetic Lineages of Canadian PRRSV-2 Reveal Transboundary Spread and Two Novel Sub-Lineages

Today we are sharing a recent publication from the VanderWaal lab looking at PRRSV sequences from Canada. The full publication is available in open access on the journal Pathogens’ website.

Less Invasive Sampling Methods for PRRSV Detection in Exposed Gilts

Today, we are sharing a very recent publication from Dr. Mariana Kikuti in collaboration with the MSHMP team. Their project looked at the sensitivity of blood-soaked filter papers, blood-soaked swabs, oral swabs and tonsil oral scrubbings when compared to serum samples to detect PRRSV. The full manuscript is available in open-access on the journal’s website.

Evaluating cardiac puncture blood collection as a reliable and biosecure postmortem diagnostic tool in swine

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.

MSHMP researchers Claudio Marcello Melini, Mariana Kikuti, Xiaomei Yue, and Cesar A. Corzo take a look at cardiac puncture, an alternative tool for blood collection during outbreak investigations.
