Do Opossums Carry A Disease That Kills Horses?

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..

Can you ride a horse that has EPM?

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.

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.

Do possums carry diseases fatal to horses?

Answer: 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.

Can a horse 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.

What are signs of EPM?

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.

How long can horses live with EPM?

The early or mildly infected diseases can be cured within 28 to 30 days whereas the moderately infected horses may need more than 120 days to be able to function normally.

What disease can horses get from possums?

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.

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.

How much does it cost to test a horse for EPM?

The test costs $61 per sample and the results usually come back within a week. Spinal tapping allows your veterinarian to look at your horse’s cerebrospinal fluid (CSF). A spinal tap better detects infection but it’s more invasive than a blood test.

Should I let a possum live under my house?

To a possum, the crawlspace under a house seems like a good place to set up its own home. Dark, ground level and protected from the elements, a home’s crawlspace has the same qualities a possum would seek for its den in the wild. Most homeowners, on the other hand, prefer not to have a possum living under their house.

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.

Do all possums carry EPM?

How EPM Is Transmitted and What It Does to a Horse. 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.

Why are possums bad for horses?

Opossums can transmit Equine Protozoal Myeloencephalitis (EPM) to horses. It is caused by a protozoal parasite whose eggs are shed in opossum feces. Infected animals show various signs of illness, including symptoms of central nervous system disease.
