The Department of Agriculture, Forestry & Fisheries has just issued an update on the Contagious Equine Metritis situation in South Africa.
Contagious equine metritis (CEM) is a transmissible, venereal disease of horses caused by the bacterium Taylorella equigenitalis.
- CEM is commonly transmitted directly during sexual intercourse between undetected CEM positive breeding mares and stallions. It can also occur indirectly by artificial insemination.
- Initial exposure to the disease usually results in infertility. An infected mare may fail to conceive or she may spontaneously abort.
- Stallions exhibit no clinical signs but can carry the CEM bacteria on their external genitalia for years.
- Undetected carrier mares and stallions are the source of infection for acute outbreaks of the disease.
