11 Florida Horses Test Positive for Contagious Equine Metritis

The recent outbreak of contagious equine metritis (CEM) in Orange County, Florida, has raised concerns within the horse community. With eleven horses testing positive for the disease and 86 horses exposed, the situation is being closely monitored by the Equine Disease Communication Center (EDCC) through their Health Watch program. The cases are linked to a domestic pony stallion that bred mares via live cover, highlighting the ease with which CEM can spread among horses.

CEM is a venereal disease of horses caused by the bacteria Taylorella equigenitalis. It can have a significant impact on the fertility of both mares and stallions. The United States is considered to be CEM-free, making it a foreign animal disease that is reportable at both the federal and state levels. The potential economic losses to the U.S. horse industry if the disease were to become established here are substantial, underscoring the importance of swift and effective containment measures.

The transmission of CEM occurs during breeding or through contact with contaminated objects. Due to its highly contagious nature, the disease can be challenging to detect and control. Infected mares may not exhibit obvious signs of illness, while stallions can carry the bacteria without showing any symptoms. In some cases, mares can also become carriers of the disease, passing it on to their foals. This cycle of infection and transmission underscores the need for thorough testing and monitoring within affected populations.

The Equine Disease Communication Center (EDCC) plays a crucial role in disseminating accurate and timely information about infectious diseases in horses. Supported by industry donations, the EDCC provides open access to disease reports, helping to educate and inform horse owners, veterinarians, and other stakeholders about the latest developments in equine health. By leveraging the resources and expertise of the EDCC, the horse community can stay informed and take proactive measures to prevent the spread of diseases like CEM.

In response to the outbreak in Orange County, Florida, it is essential for horse owners and caretakers to remain vigilant and follow recommended biosecurity protocols. This includes implementing strict hygiene practices, such as disinfecting equipment and facilities, isolating infected animals, and limiting contact between horses. Regular testing and monitoring for CEM are also crucial to identify and contain any new cases that may arise.

Overall, the recent cases of CEM in Orange County serve as a reminder of the ongoing threat posed by infectious diseases in the horse community. By staying informed, practicing good biosecurity measures, and working together to prevent the spread of diseases, horse owners can help protect the health and well-being of their animals. Through collaboration and proactive management, the horse industry can continue to thrive while safeguarding against potential outbreaks of CEM and other infectious diseases.
