Contagious Equine Metritis

Contagious equine metritis (CEM) is a transmissible venereal disease in horses, caused by a bacterium called Taylorella equigenitalis. CEM is highly contagious and can have a devastating effect on equine reproductive activity. This disease occurs naturally only in horses, and all breeds are susceptible

In Canada, CEM is a reportable disease under the Health of Animals Regulations, and all cases must be reported to the Canadian Food Inspection Agency (CFIA).
