Contagious Equine Metritis

News Worthy: United States Department of Agriculture, Animal and Plant Health Inspection Service, following:

"What is CEM?Contagious Equine Metritis (CEM) is a sexually transmitted disease among horses caused by a bacteria Taylorella equigenitalis. Clinical signs may include a mucopurulent vaginal discharge in up to 40% of affected mares, abortion and infertility. Stallions typically show no clinical signs. Stallions and mares can become chronic carriers of CEM and be sources of infection for future outbreaks. The transmission rate is high and naturally occurs by mating, but contaminated instruments and equipment may be an indirect source of infecting mares and stallions. The bacteria can also be spread via semen collected for artificial insemination."
