OPPCONCERNED SHEEP BREEDERS SOCIETY
— ASI TO PILOT NEW OPP ERADICATION PROJECT —
This two-year project, which is being led by ASI Animal Health Committee Co-chair Dr Cindy Wolf, builds on Minnesota’s Trial. The deadline to apply has passed but we’ll post updates here as information is received.
While eradication needs to be the main emphasis at present, it is equally important to identify sources of test-negative replacements and hopefully this project will eventually expand to accomplish just that. Also see our ‘Library’ page.
— ERADICATION TRIAL COMPLETED IN MINNESOTA —
In late 2013, following new research suggesting that OPP eradication may be possible without severe culling of ewes or orphaning lambs, the Minnesota Lamb & Wool Producers accepted an invitation to collaborate with the Minnesota Board of Animal Health, University of Minnesota Veterinary Diagnostic Laboratory and College of Veterinary Medicine, USDA Veterinary Services, and the OPP Society in a trial to test a new eradication strategy.
The Trial began in the Fall of 2013 and was completed in late 2017. The four producers who persisted through all 4-plus years have been refreshingly open regarding what happens in the real world vs. best laid plans. Their personal accounts, as well as details of the management and testing protocols now proven to work in any flock, are included in our 16-page final report which can be found on the ‘Library’ page.

— ‘ELITEST’ ELISA NOW AVAILABLE IN THE U.S. —
Of more than 30 ELISAs noted for detection of OPP/CAE, ‘Elitest’ is the only one validated to standards of the World Organization for Animal Health (OIE). This test was developed through a collaborative effort by laboratories in the UK, Spain, Italy and Belgium, and is used in control and eradication programs worldwide, including Ontario and Minnesota.
‘Elitest’ is now offered by the University of Minnesota Veterinary Diagnostic Laboratory with a fee of $6.25 per sample plus a $10 accession fee for each lot submitted. No out-of-state surcharge. Submit 1 ml of serum for this test.

— GENETIC TEST FOR OPPV SUSCEPTIBILITY —
This test, TMEM154, was introduced in 2013 by GeneSeek, a Neogen Corporation division in Lincoln, Nebraska. It was developed by USDA scientists at the Meat Animal Research center (USMARC) in Clay Center, Nebraska, working with GeneSeek, and is based on results validated in collaboration with USDA colleagues in Idaho and Washington state.
The test reports risk level for OPPv infection. It does NOT tell you whether or not an animal is infected!
Animals at lowest risk can still become infected, and at least one strain of the OPP virus has adapted to infect all sheep regardless of their TMEM154 genotype. But removing the most susceptible animals may, over time, be beneficial in efforts to reduce a flock’s overall infection level.
TMEM154 can be run on a sample of whole blood (1-2 cc in a lavender-topped EDTA tube) or on a blood-spot card (cards available from GeneSeek for $1 each). Cost is $12. See our ‘Library’ page for related info and submission form.
Important Note: While some may opt to employ this new DNA test in their OPP control efforts, at this time the OPP Society does not advocate genetic selection as a route to eradication. In summary, ALL breeds are susceptible to infection with the virus, so ALL shepherds need to be aware of this risk and the related need for biosecurity.
