PATHOLOGY

Detailed explanation-1: -EPM is a disease that affects the brain and spinal cord. It’s caused by the microbe, Sarcocystis neurona, commonly found in the opossum.

Detailed explanation-2: -Equine protozoal myeloencephalitis (EPM) is caused by the protozoal parasites Sarcocystis neurona and Neospora hughesi, although most cases are due to S. neurona. The definitive host for S. neurona is the opossum, and horses become infected when they ingest feed or water contaminated with opossum feces.

Detailed explanation-3: -EPM is caused by a parasite, Sarcocystis neurona, spread in the feces of opossums. Hay, feed and water contaminated by parasite-infested waste are the most likely sources of infection.

Detailed explanation-4: -Equine protozoal myeloencephalitis (EPM) is a serious disease of horses, and its management continues to be a challenge for veterinarians. The protozoan Sarcocystis neurona is most commonly associated with EPM.
