Endometritis, commonly referred to as EPM, is a reproductive disorder that affects horses worldwide. It is a significant concern for horse owners and equine professionals alike, as it can lead to infertility, abortion, and even mare mortality. Despite its prevalence, EPM remains a poorly understood condition, and its diagnosis and treatment can be challenging. In this overview, we will explore the commonality of EPM in horses, its causes, symptoms, and management options.
What is EPM in Horses?
EPM is a chronic inflammatory condition that affects the endometrium, the lining of the uterus in mares. It is characterized by the presence of inflammatory cells, such as neutrophils and macrophages, in the endometrial tissue. This inflammation can lead to the formation of scar tissue, adhesions, and fibrosis, which can cause infertility and other reproductive problems.
Prevalence of EPM in Horses
Studies have estimated that EPM affects up to 20% of mares in the United States, making it one of the most common reproductive disorders in horses. The prevalence of EPM varies depending on factors such as breed, age, and geographic location. For example, some studies have found that EPM is more common in Thoroughbred and Quarter Horse mares, while others have reported higher rates of EPM in mares over the age of 10.
Causes and Risk Factors of EPM
The exact causes of EPM are not fully understood, but several risk factors have been identified. These include:
- Reproductive tract infections
- Endometritis
- Uterine fibrosis
- Previous reproductive trauma
- Genetic predisposition
In this overview, we will delve deeper into the causes, symptoms, and management options for EPM in horses. We will also explore the latest research and treatment options for this complex and challenging condition.
How Common Is Epm In Horses?
EPM, or Equine Protozoal Myeloencephalitis, is a neurological disorder that affects horses worldwide. It is caused by the protozoan parasite Sarcocystis neurona, which is typically found in the muscles of infected horses. In this article, we will explore the prevalence of EPM in horses, its symptoms, diagnosis, and treatment options.
Prevalence of EPM in Horses
EPM is a relatively common disease in horses, especially in the United States. According to the American Association of Equine Practitioners (AAEP), EPM is estimated to affect around 1-3% of all horses in the country. However, the prevalence of the disease can vary depending on several factors, such as the region, breed, age, and sex of the horse.
A study published in the Journal of Veterinary Internal Medicine found that EPM was more common in horses aged 1-5 years, with a prevalence of around 2.5%. Another study published in the Equine Veterinary Education journal found that EPM was more common in horses living in areas with high humidity and temperatures, such as the southeastern United States.

Symptoms of EPM in Horses
The symptoms of EPM in horses can vary depending on the severity of the infection and the location of the parasites in the brain and spinal cord. Common symptoms include:
- Ataxia (loss of coordination and balance)
- Weakness or paralysis of the limbs
- Difficulty standing or walking
- Head tilt or tremors
- Abnormal behavior, such as anxiety or aggression
In severe cases, EPM can cause seizures, blindness, and even death. It is essential to recognize the symptoms of EPM early on to prevent complications and improve the chances of successful treatment.
Diagnosis of EPM in Horses
Diagnosing EPM can be challenging, as the symptoms can be similar to those of other neurological disorders. A diagnosis typically involves a combination of clinical examination, laboratory tests, and imaging studies. The following tests may be performed:
- Complete blood count (CBC) to rule out other infections
- Serum biochemistry profile to assess liver and kidney function
- Imaging studies, such as MRI or CT scans, to visualize the brain and spinal cord
- Cerebrospinal fluid (CSF) analysis to detect the presence of Sarcocystis neurona
A definitive diagnosis of EPM can only be made by detecting the parasite in the CSF or brain tissue. However, this requires a biopsy or autopsy, which is not always possible or practical.
Treatment of EPM in Horses
There is no cure for EPM, but treatment can help manage the symptoms and improve the quality of life for affected horses. The following treatment options are available:
- Antiprotozoal medications, such as ponazuril or sulfadiazine
- Supportive care, such as physical therapy and rehabilitation
- Pain management, such as analgesics and anti-inflammatory medications
The goal of treatment is to reduce the severity of the symptoms and prevent complications. In severe cases, hospitalization may be necessary to provide intensive care and monitoring.
Prevention of EPM in Horses
Preventing EPM is crucial, especially in areas where the disease is common. The following measures can help reduce the risk of infection: (See Also: Do Horses Ever Have Twins)
- Keeping horses in a clean and dry environment
- Providing adequate nutrition and exercise
- Monitoring horses for signs of illness and seeking veterinary care promptly
- Using protective measures, such as fly masks and insect repellents, to reduce the risk of insect-borne transmission
It is also essential to work with a veterinarian to develop a prevention plan that is tailored to the specific needs and risks of your horse.
Recap
EPM is a common neurological disorder in horses, caused by the protozoan parasite Sarcocystis neurona. The prevalence of the disease can vary depending on several factors, including the region, breed, age, and sex of the horse. Symptoms of EPM can include ataxia, weakness, and abnormal behavior, and diagnosis typically involves a combination of clinical examination, laboratory tests, and imaging studies. Treatment options include antiprotozoal medications, supportive care, and pain management. Prevention measures, such as keeping horses in a clean and dry environment and monitoring for signs of illness, can help reduce the risk of infection.
It is essential to work with a veterinarian to develop a prevention plan and to seek prompt veterinary care if your horse is showing signs of illness. With proper treatment and care, many horses with EPM can lead happy and healthy lives.

Frequently Asked Questions
What is EPM in horses?
EPM, or Equine Protozoal Myeloencephalitis, is a neurological disorder caused by a protozoan parasite called Sarcocystis neurona. It affects the horse’s central nervous system, leading to a range of symptoms including stumbling, weakness, and loss of coordination. (See Also: How Many People Ride Horses)
How common is EPM in horses?
EPM is considered a relatively rare condition in horses, but it can occur in any horse, regardless of age, breed, or sex. According to the American Association of Equine Practitioners, the prevalence of EPM in horses is estimated to be around 1-2% in the United States, although it may be more common in certain regions or populations of horses.
What are the symptoms of EPM in horses?
The symptoms of EPM can vary depending on the severity and location of the infection, but common signs include stumbling, weakness or paralysis of the legs, loss of coordination, and difficulty standing or walking. In some cases, horses may also exhibit signs of pain, such as kicking or biting at their belly.
How is EPM diagnosed in horses?
Diagnosing EPM can be challenging, as the symptoms can be similar to those of other conditions. A definitive diagnosis typically requires a combination of clinical signs, laboratory tests, and imaging studies. The most common diagnostic tests include blood tests to detect antibodies against S. neurona, as well as imaging studies such as MRI or CT scans to visualize the horse’s brain and spinal cord.
Can EPM be treated in horses?
Yes, EPM can be treated in horses, but the prognosis is often guarded, and the condition can be challenging to manage. Treatment typically involves a combination of antiparasitic medications, anti-inflammatory drugs, and supportive care, such as physical therapy and rehabilitation. In some cases, surgical intervention may be necessary to relieve compression on the spinal cord or to remove infected tissue. With proper treatment and care, some horses with EPM can recover and return to their normal activities, while others may experience chronic disability or relapse.
