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.
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.
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.
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.
The causative agent of the symptoms of tetanus is Clostridium tetani.
Symptoms include unnatural eye colour, loss of hair, loss of flesh, and cravings for flesh and brains.
EPM means Earning per minute. When we calculate CM we need to know EPM. Example SMVxEPM=CM.

That is one of the symptoms of EPM. This is a serious neurological issue due to protozoa in the spinal cord and/or brain.
Nothing in the description you give points to EPM. Dietary imbalance or metabolic disease would be more likely with what you describe, but a full veterinary exam would be recommended to determine the cause of the symptoms you are seeing.
That means how fast it advances.
No, EPM is not transmitted from horse to horse. EPM is contracted by eating feedstuffs or drinking water that has been contaminated by oppossum feces wich contain S. neurona sporocysts--this is the infective stage of the S. neurona lifecycle. This infective stage is not shed in equine feces.
While some veterinarians in Kentucky may have vaccinated against EPM in the past, there is no longer and EPM vaccine on the market. Fort Dodge, while able to prove the safety of their vaccine and having it conditionally licensed for several years, could not prove efficacy and so lost the license for the vaccine.
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.
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

There is a new drug that has just been approved by the FDA called Marquis.
EPM is detected through physical exam, blood testing and cerebrospinal fluid testing. It is important to note that a positive blood test may simply indicate exposure to the parasite and not disesae, therefore a diagnosis should not be made based upon a blood test alone.
