​

Genetics and OPP:

While some may opt to employ the new DNA testing in their OPP control efforts, USDA researchers have since found that some strains of the OPP virus have adapted to infect sheep regardless of their genotype. Therefore, at this time the OPP Society does not advocate genetic selection as a route to eradication. Concentration should be on removing the virus, not controlling it, or you will be right back where you began in a few years. In summary, all breeds are susceptible to infection, so all shepherds need to be aware of this risk and the need for biosecurity.

​

NOTE: The first two files below, a 2013 slide show and related paper, planted the seeds for Minnesota’s OPP Trial.
