Horses are magnificent creatures that have been an integral part of human history and culture. From transportation to companionship, horses have played a vital role in our lives. As horse owners and enthusiasts, it is essential to understand the various aspects of horse care and management. One such aspect is EPM, which stands for Equine Protozoal Myeloencephalitis. In this article, we will delve into the world of EPM in horses, exploring its definition, causes, symptoms, diagnosis, treatment, and prevention.
What is EPM in Horses?
EPM is a neurological disease caused by a protozoan parasite called Sarcocystis neurona. This parasite is typically found in the feces of opossums, which are the primary carriers of the disease. When a horse ingests the parasite through contaminated food or water, it can lead to a range of symptoms affecting the horse’s nervous system.
Causes and Transmission
The primary cause of EPM is the ingestion of the Sarcocystis neurona parasite through contaminated food or water. This can occur when a horse eats or drinks something that has come into contact with an opossum’s feces. The parasite then infects the horse’s brain and spinal cord, leading to a range of symptoms.
Symptoms
The symptoms of EPM can vary depending on the severity of the infection. Common symptoms include:
- Ataxia (loss of coordination)
- Weakness in the legs
- Difficulty walking or standing
- Head tilt or tremors
- Changes in appetite or behavior
Diagnosis and Treatment
Diagnosing EPM can be challenging, as the symptoms are similar to those of other neurological diseases. A veterinarian may perform a series of tests, including:
- Neurological examination
- Imaging tests (e.g., MRI, CT scans)
- Laboratory tests (e.g., blood tests, cerebrospinal fluid analysis)
Once diagnosed, treatment typically involves a combination of antiprotozoal medication and supportive care. The goal of treatment is to alleviate symptoms and manage the disease.
Prevention
Preventing EPM is crucial in reducing the risk of infection. Here are some steps you can take:
- Keep your horse’s living area clean and free of opossums
- Provide a safe and healthy environment for your horse
- Avoid feeding your horse contaminated food or water
- Regularly monitor your horse’s health and behavior
By understanding EPM in horses, you can take proactive steps to prevent and manage this disease, ensuring the health and well-being of your equine companion.
What Is Epm In Horses?
EPM, or Equine Protozoal Myeloencephalitis, is a neurological disorder that affects horses. It is caused by a protozoan parasite called Sarcocystis neurona, which is typically found in the muscles of horses. The parasite is usually transmitted to horses through the ingestion of contaminated feed or water, or through contact with an infected horse. (See Also: When Do Horses Mature Mentally)
What Are the Symptoms of EPM in Horses?
The symptoms of EPM in horses can vary depending on the severity of the infection and the individual horse’s response to the parasite. Some common symptoms include:
- Ataxia (loss of coordination and balance)
- Weakness or paralysis of the legs
- Difficulty standing or rising
- Loss of appetite
- Weight loss
- Difficulty swallowing
- Changes in behavior, such as depression or anxiety
In severe cases, EPM can cause more serious symptoms, including:
- Seizures
- Coma
- Death
How Is EPM Diagnosed in Horses?
Diagnosing EPM in horses can be challenging, as the symptoms can be similar to those of other neurological disorders. A veterinarian will typically perform a physical examination and take a complete medical history to help diagnose EPM. The veterinarian may also perform the following tests:
- Neurological examination
- Imaging tests, such as MRI or CT scans
- Blood tests to rule out other conditions
- Spinal fluid analysis
The diagnosis of EPM is typically based on a combination of these tests and the veterinarian’s clinical experience.
How Is EPM Treated in Horses?
There is no cure for EPM, but it can be managed with treatment. The goal of treatment is to reduce the severity of the symptoms and prevent further progression of the disease. Treatment typically involves a combination of the following:
- Antiparasitic medications, such as pyrimethamine or trimethoprim-sulfamethoxazole
- Anti-inflammatory medications, such as corticosteroids
- Supportive care, such as physical therapy and nutritional supplements
In severe cases, hospitalization may be necessary to provide supportive care and manage symptoms.
How Can EPM Be Prevented in Horses?
Preventing EPM in horses involves reducing the risk of infection and minimizing the spread of the parasite. Some ways to prevent EPM include:
- Providing clean water and feed
- Avoiding contact with infected horses
- Using fly control measures to reduce the risk of insect transmission
- Using antiparasitic medications as directed by a veterinarian
It is also important to monitor horses for signs of EPM and seek veterinary care immediately if symptoms develop.
Conclusion
EPM is a serious neurological disorder that affects horses. It is caused by a protozoan parasite and can be transmitted through contaminated feed or water, or contact with an infected horse. Symptoms can vary depending on the severity of the infection and the individual horse’s response. Diagnosis is based on a combination of tests and clinical experience, and treatment involves a combination of antiparasitic and anti-inflammatory medications, as well as supportive care. Prevention involves reducing the risk of infection and minimizing the spread of the parasite. By understanding the causes, symptoms, diagnosis, treatment, and prevention of EPM, horse owners can take steps to protect their horses and ensure they receive the best possible care.

Frequently Asked Questions: What Is Epm In Horses?
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 weakness, ataxia, and paralysis.
How is EPM transmitted to horses?
EPM is typically transmitted to horses through the ingestion of contaminated food or water, or through contact with an infected horse. The parasite is often found in the feces of opossums, which can contaminate horse feed or water.
What are the symptoms of EPM in horses?
The symptoms of EPM in horses can vary depending on the severity of the infection. Common symptoms include weakness, ataxia (loss of coordination), paralysis, and difficulty swallowing. In severe cases, EPM can cause seizures, blindness, and even death.
How is EPM diagnosed in horses?
EPM is typically diagnosed through a combination of clinical signs, laboratory tests, and imaging studies. Laboratory tests may include blood tests, cerebrospinal fluid analysis, and PCR (polymerase chain reaction) testing. Imaging studies such as MRI or CT scans may also be used to rule out other conditions.
Can EPM be treated in horses?
Yes, EPM can be treated in horses with antiprotozoal medications, such as ponazuril or diclazuril. Treatment is typically long-term, and may require several months of medication to ensure that all of the parasites are eliminated.
