Contagious Equine Metritis Ohio Update

March 17, 2009 at 7:30 am 2 comments

A total of 13 stallions have been confirmed by USDA’s National Veterinary Services Laboratories (NVSL) as positive for Taylorella equigenitalis, the causative organism of contagious equine metritis (CEM). In addition to the positive stallions, the NVSL has confirmed that three mares have CEM. None of the positive horses have yet been identified as the source of the outbreak; the epidemiologic investigation continues to pursue all available information relative to determining the origin of this outbreak, but no conclusions can yet be drawn. According to Leah C. Dorman, Assistant State Veterinarian Ohio Department of Agriculture:

Here in Ohio, we have had a total of 38 mares that have been exposed to CEM. Of these 38 mares: 23 have been released from quarantine (19 completed testing and four moved out of state to complete testing); nine have started the testing process; and six have not yet started testing. Ohio also has had 14 stallions that were exposed to CEM. Ten of these stallions have started the testing/treatment process. One stallion has completed the testing process and is negative. Due to the fact that CEM is a foreign animal disease, state or federal animal health officials are required to train and witness testing and treatment protocols performed by veterinary practitioners. We have good cooperation from both the equine community and practicing veterinarians. Thanks for your interest and support.

For Ohio specific CEM-related questions, please contact either Dr. Leah Dorman at the Ohio Department of Agriculture (614-728-6220) or Dr. Daniel Harpster at USDA-APHIS-Veterinary Services (614-309-2832).

    It is a known fact that it was brought to Degraff stables from WI.
    13 OF THE STALLIONS IN OHIO HAD NO CONTACT WITH ANY WI HORSE & SHOULD HAVE BEEN RELEASED FROM QUARANTINE.
    But ODA would lose federal funds if they did. Once a horse is quarantined they have to go through the same protocol as a positive stud even when all their test & mare tests are negative. Now you know why horses are standing out of the state of Ohio. This whole outbreak is about showing the Federal goverment why funding is needed. Not the health of the horse. Final treatment involves nitrofurason.

      First, there are no positive cases in the state of Ohio as of 4/7/09; there are ‘exposed’ cases. Second, in response to the Degraff stables comment there is a tremendous amount of misinformation. Please contact ODA at the information above for the latest information.
