Contagious Equine Metritis: A Review
How is CEM transmitted and spread? Once merritis organism has been eliminated, the horse may be used for breeding again. These tests cnotagious positive 10 or more days after infection. In mares, initial exposure to the disease usually results in a large amount of vaginal discharge 12 to 14 days following natural breeding with an infected stallion.
The severity of disease in mares varies. Although most contagious equine metritis outbreaks involved Thoroughbreds, infection in other breeds has also occurred. Infected stallions tend to be the major source of infection, as they can harbour the disease for years without showing any clinical signs. Sample collection and laboratory methods for the diagnosis of contagious equine metritis are described.
Treatment of stallions is successful. Inhibition of the CEM organism by the normal flora of the reproductive tract. The disease can also be transmitted via artificial insemination. Responses of mares to rechallenge with the organism of contagious equine metritis It is relatively easy to eliminate the carrier state in stallions using local disinfectant.
Venereal infection in thoroughbreds with Bacillus proteus mirabilis. All horses of breeding age that are imported into Canada, from countries where CEM is endemic, must be tested for the disease before entering Canada. There is no human health risk associated with CEM.
Blood tests are not possible for stallions. Stallions do not show signs of infection. The main outward sign is a vaginal discharge which may range from very mild to extremely prolific.
The course of serum antibody development in two ponies experimentally infected with contagious metritis.
Clinical signs have not been observed in stallions. This disease only affects horses, however all breeds are susceptible. Views Read Edit View history. CEM is suspected when multiple mares that are bred by the same stallion experience short-term infertility and have vaginal discharge.
