In reference to diseases, the initials CEM stand for what?

The initials CEM stand for Contagious Equine Metritis, which is a sexually transmitted disease in horses caused by the bacterium Taylorella equigenitalis. This disease primarily affects mares, leading to inflammation of the reproductive tract and can result in infertility or reduced fertility in affected animals. It is significant in horse breeding and management because it can be easily transmitted during breeding practices, making diagnosis and control essential for maintaining healthy breeding stock.

Understanding the nature of CEM is important for any equine health professional or breeder, as it emphasizes the need for testing and treatment to prevent the spread of the disease. This is particularly relevant in breeding facilities where multiple horses are housed, making biosecurity measures critical in preventing the incidence of CEM.
