The feces of opossums may contain sporocysts - cysts that contain spores that can reproduce asexually. Horses can ingest these sporocysts with feed, grass or water contaminated with opossum feces. The protozoa can leave lesions on the spinal cord and brain stem. It is this neurological damage that can cause the various symptoms of EPM.

Can you horse have a normal life after EPM and treatment?

Some horses can have a normal life after EPM with prompt diagnosis and treatment. However, the degree of recovery can vary depending on the severity of the infection and the response to treatment. It is essential to work closely with a veterinarian to develop a comprehensive treatment plan and provide ongoing care to improve the chances of a successful recovery.


What animal carries EPM?

The protozoan parasite that causes EPM has an interesting lifecycle where it encysts in the muscle of a host animal and does no damage to that animal and is not capable of causing EPM or neurological disease in any species. It is only when muscle/tissue containing the encysted lifestage is then eaten by a possum that it then matures into the infective stage and passed in the feces of the possum and then may cause disease in horses, seals, humans, etc. The encysted stage can be found in cats, birds, armadillos and possibly other types of animals, but again it is not dangerous to horses in this stage. But this is why you should clean up dead animals as quickly as possible so that they don't serve as an infected food source for possums (who are carrion eaters) and thus infect the possums with the protozoa and continue the life cycle.


What are the symptoms of EPM?

EPM can present with any number of neurological deficits. Lack of coordination, stumbling, dragging toes and asymmetrical loss of muscle are common signs of EPM. EPM does not present with a fever which is one of the signs used to differentiate it from infectious neurological diseases such as Eastern and Western Equine Encephalitis or West Nile Virus.


What causes muscle tremors in horses?

Muscle tremors in horses can be caused by a variety of factors such as mineral imbalances, electrolyte abnormalities, nerve damage, exertional rhabdomyolysis (tying-up), or certain diseases like equine protozoal myeloencephalitis (EPM). It's important for a veterinarian to assess the horse to determine the underlying cause and appropriate treatment.


What causes diarrhoea in horses?

Diarrhoea in horses can be caused by a variety of factors, including dietary changes, infectious agents (such as bacteria or parasites), stress, and certain medications. It is important to consult a veterinarian to determine the underlying cause and appropriate treatment for diarrhoea in horses.

Does EPM cause weight loss in horses?

EPM does cause what is commonly termed "weight loss" in horses but a more accurate term is "muscle loss". This is because the protozoan parasite causes damage in the central nervous system that affects the horse's ability to feel and thus use portions of it's body. With lack of use, muscle deteriorates and thus a horse may loose weight from the loss of muscle.


What is EPM in garment ind?

EPM means Earning per minute. When we calculate CM we need to know EPM. Example SMVxEPM=CM.


A neighbor advised you that if a possum poops in horse feed the horse will contract some kind of disease and die True?

It is possible. The disease your neighbor is talking about is equine protozoal myeloencephalitis (EPM). Currently it is generally accepted that EPM is caused by aberrant migration of a parasite (Sarcocystis neurona) through the central nervous system of a horse. S. neurona is commonly found in raccoons, where it is an intestinal parasite that is transmitted through the feces.Treatment for EPM is generally symptomatic and not particularly helpful; the damage is caused by the parasite and there isn't much a veterinarian or anyone else can do to reverse the damage to the neurons. Most horses diagnosed with EPM are either retired to pasture or breeding (if the damage is mild) or are euthanized for humane reasons.However, there are plenty of horses exposed to raccoon feces in their feed who never get EPM, and there are some horses who develop EPM but have no history of exposure to raccoons.

Do possums carry diseases fatal to horses?

Opossums don't carry a disease fatal to horses, they more like leave it behind. When consumed, opossum fecies can cause a horse to develop EPM (equine protozoal myeloencephalitis) which is a neurological disease. The horse may seem dissorientated, dizzy, unstable, and overall act very odd. It is treatable but a vet examination and testing is the first action one should take. Recovery may not be 100% and your horse may not seem themselves. I have a horse that tested positive with EPM and showed all the symptoms, was treated for it, and cured 100%. If you suspect your horse to have EPM, again call your vet. To try and avoid a horse from contracting EPM and if you suspect there is a possibility of them coming in contact with opossum feceis (or any other kind for the matter) try feeding them hay in a hay bag and off the ground outside, feed them hay in a stall if possible, or frequently muck their fields. Oh and the FULLY answer the question, yes if not caught or treated properly EPM is commonly fatal


What parasite causes Equine Protozal Myeloncephalitis?

Opossums are the definitive host for Sarcocystis neurona, which is the parasite that causes EPM (equine protozoal myeloencephalitis. The parasite is excreted from opossums in their manure which can then be ingested by the horse while grazing or drinking water.


ARE possums dangerous to horses?

yes, Equine Protozal Myelitis is a "bug" that can be passed.
