New York State has identified and quarantined nine mares potentially exposed to contagious equine metritis (CEM).
State Agriculture Commissioner Patrick Hooker has alerted horse owners and breeders to the potential exposure of their horses to CEM, a contagious venereal disease.
Nine known stallions in the United States have so far tested positive for CEM and have potentially exposed about 300 other horses, including nine mares in New York State.
As potentially exposed horses are identified, they are placed under restrictions by state and federal animal health authorities, pending three consecutive negative test results.
Officials have quarantined the nine exposed mares in New York State and have begun testing.
None of the potentially exposed mares in New York State or other states has tested positive for CEM at this time.
CEM can be spread when horses are bred, or congenitally from mares to their foals. While natural breeding is more likely to spread the infection, horses involved in artificial breeding can also be exposed.
Infected stallions seldom, if ever, show outward signs of infection, but may act as carriers of the disease.
There are nine stallions that have tested positive for CEM. They are:
Gentlemen Send Roses, a paint horse from Indiana
Hot Lopin Sensation, a quarter horse from Kentucky
Indian Artifacts, a quarter horse from Kentucky
Invited Back, a paint horse from Indiana
Nanning 374, a friesian from Wisconsin
Potential Asset, a quarter horse from Texas
Potential Investment, a quarter horse from Kentucky
Repeated in Red, a quarter horse from Kentucky
Zips Heaven Sent, a paint horse from Indiana
CEM may render mares infertile or may cause horses to spontaneously abort, however the disease can be treated with antibiotics and disinfectants.
