detection – Swine in Minnesota

What is the probability of detecting a new incursion of PRRS into a PRRS-free region of Denmark within the first month?

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.

Mira Willkan, Lorraine Chapot, Angus Cameron, Søren Kjærgaard Boldsen, and Mette Fertner share the results of their study assessing how sensitive the current PRRS regional surveillance system in Denmark is and explore alternative surveillance systems. Could they detect a new PRRS introduction in less than a month?

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.

Postmortem Sampling in Piglet Populations for PRRS Detection

Today, we are sharing a recent publication from the MSHMP team comparing different piglet postmortem samples to detect PRRS. The article is available in open access on the Journal’s website.

Evaluation of oral fluid as an aggregate sample for early detection of ASF

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.

Since ASF has been found in the Dominic Republic last week, swine producers are concerned about it spreading into the United States. Early detection would be essential to ensure a rapid response and containment of the disease. This week, the MSHMP team shares the summary of a Canadian study looking at using oral fluids as a tool to diagnose ASF.

Key Points

Oral fluid samples may be used as a low labor, cost effective alternative sample source for rapid detection of ASFV during ASF surveillance.
ASFv genome was detected in oral fluids at low-to-moderate levels as early as 3-5 days post infection, before clinical symptoms started.
Further research is needed to understand limitations and best practices of oral fluid sampling for ASFv
