Contagious Equine Metritis Treatment

Methods of treating the disease.


The mare cannot be successfully treated until the CEM bacteria clear from the uterus, a process that may take several months.

The external genitalia of the mare and stallion can be treated with disinfectants and antibiotics. Due to the effectiveness of this treatment, surgical removal of the clitoral sinuses is rarely required.

  • Once daily for 5 consecutive days, the external genitalia should be gently scrubbed with 2-percent chlorhexidine in a mild detergent solution and rinsed with warm saline.
  • The external genitalia should then be coated with an antibiotic ointment, such as nitrofurazone.
  • A disadvantage of this treatment is the destruction of the normal flora and the potential overgrowth by opportunistic pathogens such as pseudomonas and klebsiella.
