Equine protozoal myeloencephalitis.

The research article discusses Equine protozoal myeloencephalitis (EPM), a disease in horses caused by a certain type of protozoa. The disease affects the brain or spinal cord of the animal and can only be definitively diagnosed through histopathology. Currently, there are no known preventative measures or treatments for it.

Understanding EPM

• Equine Protozoal Myeloencephalitis (EPM) is a disease that primarily affects horses, producing neurological symptoms.
• It is characterized by signs of brain or spinal cord dysfunction as the protozoa damage critical parts of the central nervous system.
• The causative organism of EPM is believed to be a species of protozoa called Sarcocystis, although, actual confirmation of this is still under study.

Diagnosis of EPM

• The research states that a definitive diagnosis of EPM can only be made using histopathology of the affected spinal cord or brain.
• Histopathology is the microscopic examination of biological tissues to observe the appearance of diseased cells in detail.
• This means that tissues have to be taken from the affected horse for testing, probably after it has shown significant neurological signs, or, unfortunately, post-mortem in most cases.

Lack of Prevention and Treatment

• According to the study, there currently aren’t any preventive measures that can be taken against EPM.
• Unhelpfully, the study also revealed that there is no documented treatment available for the suspected cases of EPM, posing a significant challenge in equine health.
• The absence of preventive measures and definite cures underscores the need for further research into this disease, to better understand its course, effect, and possibly, to discover a cure.
