The effect of becoming infected by the parasite varies by horse. Due to the transport of horses and feedstuffs from one part of the country to another almost all horses are at risk.
In some cases the protozoa may cross into the horses central nervous system and damage the spinal cord andor brain causing equine protozoal myeloencephalitis EPM.
Can horses die from epm. Equine protozoal myeloencephalitis EPM is a devastating disease that can leave horses severely disabled and may result in death. Diagnosis is often difficult because the onset is very similar to other diseases especially Chagas. EPM can be deadly if left untreated but thankfully it is a treatable condition.
If you fear that your horse might have EPM dont hesitate to call your vet. As you read the sooner symptoms are recognized and treated the more likely your horse is to make a full recovery. Due to the transport of horses and feedstuffs from one part of the country to another almost all horses are at risk.
Not all horses exposed to the protozoan Sarcocystis neurona will develop the disease and show clinical signs of EPM. Some horses seem to mount an effective immune response and are able to combat the disease before it gains a foothold. All horses are susceptible to EPM but not all infected horses develop the disease.
Preventative approaches include decreasing stress and reducing exposure to opossum feces. Life After EPM. One womans account of managing the rehabilitation processand her own expectationsas her horse recovers from a severe neurological condition.
EPM stands for Equine Protozoal Myeloencephalitis. Its an infection caused by a parasite that attacks the horses nervous system. There are a couple of parasites involved and the most common carriers are opossums.
The effect of becoming infected by the parasite varies by horse. When horses do show signs it can go misdiagnosed because it can slowly progress and infect any portion of the central neurologic system mimicking other conditions. Left untreated EPM can.
The disease is equine protozoal myeloencephalitis or EPM and is transmitted from opossums to horses when they eat or drink where infected opossums have defecated. The organism responsible for EPM is a parasite Sarcocystis neurona a protozoan or microscopic single-cell organism. One may also ask can possums kill horses.
Since most horses exposed to EPM never develop the disease the causes of reinfection are likely to be the dose of organism consumed health of the horses immune system and digestive tract and possibly an immune defect in highly susceptible horses. Horses that have had EPM probably should not be allowed to graze. EPM in horses is not a very serious disease but without treatment may lead to progressive death.
Moreover treatment is a costly affair for every disease. The preventive measures for the disease I have discussed are also important for other diseases. Secondary oxidative damage also occurs which explains why vitamin E a natural antioxidant has been advocated for horses with EPM.
Experts recommend administering between 5000 and 10000 IU of natural vitamin E per day for horses with EPM. Not all horses with EPM can be saved unfortunately. This video shows a chestnut horse with the disease that was a few days later humanely euthanized for safety reasons.
Unstable horses can hurt themselves or anyone close enough to be in the way if they fall. The horse may ingest sporocysts. Horses are considered aberrant hosts because so far no evidence has been found that the protozoa complete their life cycles in horses.
In some cases the protozoa may cross into the horses central nervous system and damage the spinal cord andor brain causing equine protozoal myeloencephalitis EPM. EPM in horses can be a fatal disease. EPM is one of the most commonly diagnosed neurological diseases in horses.
Interestingly it has not been reported in mules donkeys or other non-horse equids. EPM has been found in horses from 2 months to 24 years of age. In a more recent study on proportional morbidity rate an indicator of incidence of EPM among a population of horses researchers found a higher incidence among Standardbreds Tennessee Walking.
This horse has Equine Protozoal Myeloencephalitis. Before euthanasia it had high EPM titers on the UC Davis IFAT serum. Treatment was initiated but after.
