Causes of Equine Protozoal Myeloencephalitis (EPM)
Equine Protozoal Myeloencephalitis (EPM) is a neurological disease that affects horses. It is caused by a parasite called Sarcocystis neurona, which is transmitted to horses through opossum feces. The disease affects the central nervous system and can cause severe damage if left untreated.
- Opossums – The primary cause of EPM is the opossum. When an opossum defecates on the ground, the Sarcocystis neurona cysts are released. Horses can become infected by accidentally ingesting the cysts in contaminated feed or water, or by grazing on the grass where the opossum defecated.
- Environment – Horses who live in areas with a high population of opossums are at a greater risk of contracting EPM. Wet and humid climates also increase the chances of the parasite spreading.
- Immune system – Horses with weakened immune systems are more susceptible to EPM. Stress, illness, infectious diseases, and malnutrition can all compromise a horse’s immune system and make them more vulnerable to EPM.
| Causes | Description |
|---|---|
| Opossums | The primary cause of EPM is the opossum. When an opossum defecates, the Sarcocystis neurona cysts are released. Horses can become infected by accidentally ingesting the cysts in contaminated feed or water, or by grazing on the grass where the opossum defecated. |
