Contagious Equine Metritis (CEM) Horse
Follow the link provided for an excellent article on Factsheet
"Contagious equine metritis (CEM) is a highly communicable venereal disease of horses. This disease can spread rapidly from a single asymptomatic carrier, particularly a stallion. It was first documented in the 1970s, when epidemics among thoroughbred horses spread rapidly in Europe, North and South America, Australia and other countries. Although the causative organism has been eradicated from some countries including the U.S., it is still present in others and continues to affect international trade. Infected horses do not become ill or die, but reproductive success is severely reduced. Mares develop acute metritis and fail to conceive, resulting in substantial economic losses. Additional economic costs include the cost of prebreeding tests in endemic areas, as well as surveillance screening before importation into CEM-free countries. Immunity is weak, and animals may become infected repeatedly. Imported animals or semen can cause outbreaks in CEM-free regions; in the U.S., an outbreak occurred in 2008, after an absence of more than 25 years..."
