Summary
Contagious Equine Metritis (CEM) is a bacterial venereal disease in horses. Inapparent carriers in mares and stallions complicate disease control efforts, leading to potential outbreaks.
Area of Science:
- Veterinary Science
- Microbiology
- Equine Health
Background:
- Contagious Equine Metritis (CEM) is a highly contagious venereal disease affecting horses.
- The causative agent is a fastidious, Gram-negative coccobacillus.
- CEM outbreaks have been documented internationally, including in the US, UK, Ireland, France, and Australia.
Purpose of the Study:
- To review current information on Contagious Equine Metritis.
- To highlight the clinical signs and etiological agent of CEM.
- To discuss challenges in controlling CEM due to asymptomatic carriers.
Main Methods:
- Review of existing scientific literature and case reports on CEM.
- Analysis of clinical presentations and diagnostic characteristics.
- Examination of epidemiological data and control strategies.
Main Results:
- CEM is characterized by vaginal discharge 2-10 days post-breeding.
- Shortened estrous cycles can be an indicator of endometritis.
- Asymptomatic carriers in both mares and stallions significantly hinder disease management.
Conclusions:
- CEM poses a significant threat to equine populations globally.
- Effective control requires addressing the challenge of inapparent carriers.
- Continued surveillance and information dissemination are crucial for managing CEM outbreaks.
