What does a horse with EPM look like?

Paralysis of muscles of the eyes, face, or mouth, evident by drooping eyes, ears, or lips; Loss of sensation of the face; Difficulty swallowing; and.

Head tilt with poor balance—the horse might assume a splay-footed stand or lean against stall walls for support..

Can humans get EPM?

People can get sarcocystosis. They acquire the disease by ingesting (oral) the protozoan, most common- ly through undercooked meat prod- ucts. Disease in humans can involve either intestinal infection or muscular invasion by the parasite. Usually the disease resolves on its own with no signs of illness.

What causes a horse to trip a lot?

It happens every now and then: A careless misstep or an unexpected surface change causes your horse to crumble a little under you, before he catches himself and keeps going. … Often the sign of an underlying orthopedic or neurologic problem, repetitive or severe stumbling can be dangerous for both horse and rider.

What is EPM horse disease?

Equine protozoal myeloencephalitis (EPM) is a disease of horses that affects the central nervous system. Equine obviously refers to the horse, protozoal refers to the type of organism that causes the disease and myeloencephalitis refers to that portion of the animal, which is damaged.

Can a horse with EPM be ridden?

EPM can cause nerve damage, so a reader wonders if an affected horse can be rehabilitated. … For horses that do recover, the improvement is based on the initial severity of the clinical signs (see box). However, not all horses that “improve” according to the clinical scale are able to be safely ridden again.

How long can a horse have EPM?

six to eight weeksThese products are labeled for 28 days of treatment, though how long horses need to stay on the drugs usually depends on their treatment response. Consensus statement authors say most horses with EPM are treated for six to eight weeks or longer, if clinical improvement is still apparent under treatment.

How quickly does EPM progress?

Our results indicate that EPM can manifest as long as 90 days after the parasite has crossed the blood-brain barrier (data not shown), but in most of the challenged horses evidence of infection occurred within 30 days and ataxia was present by 60 days.

What are signs of EPM?

Learn to Recognize the Symptoms of EPMAtaxia (incoordination), spasticity (stiff, stilted movements), abnormal gait or lameness.Incoordination and weakness which worsens when going up or down slopes or when head is elevated.More items…

How do you diagnose EPM in horses?

The standard of practice for diagnosis is to perform a complete neurological exam, accompanied by laboratory tests that detect an immunological response to infection. Testing of cerebrospinal fluid (CSF), with a paired serum, is more predictive of active disease than serum alone.

What causes EPM?

Equine Protozoal Myeloencephalitis (EPM) is a neurologic disease in horses caused by infection with the protozoan Sarcocystis neurona (SN). SN infects horses when they ingest the organism in contaminated feed or water. The definitive host of this organism is the opossum, which passes the organism in its feces.

Can a horse fully recover from EPM?

In fact, 80% to 90% recover completely. Horses that have mild cases tend to have a lower rate of relapse. If your horse has a severe case of EPM, the prognosis is not as good. 10% or less achieve full recovery, and the sicker the horse, the more likely it is they will have a relapse.

Is there a vaccine for EPM in horses?

18, 2000, a vaccine to prevent EPM was approved by the USDA. As of Jan. 25, a total of 43 states had approved the use of the EPM vaccine under USDA conditional licensure. The vaccine must be used under the supervision of a veterinarian.

Does EPM cause weight loss?

Parasite dose is also likely to be a factor. Horses that show clinical signs typically show the “three A’s” of EPM: asymmetry, atrophy, and ataxia. Ataxia is incoordination and not knowing where their legs are in space. Atrophy manifests in what comes across as weight loss, when really the horse is losing muscle mass.

How can you prevent EPM?

Preventive Strategies First and foremost to EPM prevention is to manage any possible contamination of horse feed or water from the primary reservoir host, the opossum. Skunks, raccoons, sea otters and even cats also can be protozoal sources. Lock away all feed containers in varmint-proof containers and rooms.

Can a possum kill a horse?

A. You are correct that opossums (not cats) are the host animal that transmits Sarcocystis neurona, the protozoan parasite that causes EPM. … Bottom line: Yes, opossums are the culprit that transmits the causative parasite of EPM to horses.

What animals carry EPM?

A few types of wild animals and all opossums can be the carrier of the protozoa for EPM. While other animals may carry the protozoa in their body, only opossums can transmit EPM. 1 The feces of opossums contain sporocysts and that is how they transmit the disease.

Can horses transfer Lyme disease to humans?

To sum up matters, flies and mosquitoes have never been shown to serve as vectors for the spirochete that causes Lyme disease. The only proven vector in the U.S. is the tick. However, horses can serve as hosts for ticks, as many horse people know.

Can dogs get EPM?

EPM-like illness has also been recorded in several other mammals, including domestic dogs and cats.

How much does it cost to treat EPM in horses?

$800-$1000). Horses that recover can still encounter temporary or permanent deficits. It is estimated that up to 30% of horses treated may experience relapse, likely due to the lack of immune support during and post treatment.

Is there a cure for EPM?

If left undiagnosed and untreated, EPM can cause devastating and lasting neurological deficits. The success rate for treated horses is high. Many will improve and a smaller percentage will recover completely, but 10-20% of cases may relapse within two years.
