Our mission is to develop patent-protected technologies for the diagnosis and treatment of animal diseases. Developing disease models, including an animal infection model, allows us to investigate disease associated with Sarcocystis neurona, diagnose early signs of Equine Protozoal Myeloencephalitis (EPM), and test treatments in the horse. We currently investigate inflammation associated with neurodegenerative diseases.

I don't know about performance but my grades in chemistry have improved! Levamisole HCl, originally described for treating helminth infections, is also used for modulating immune responses in humans and animals. Although the mechanisms of actions of levamisole HCl on signal transduction pathways in horses have not been thoroughly defined, levamisole [...]

We are conducting an EPM-treatment effectiveness study that will compare the treatment response between two drugs. The new drug is compared to a drug selected from those that are available commercially. The commercially available drug is called the Active, we will compare our treatment to an Active. The FDA's Freedom [...]

Affordable Testing

Affordable Testing

Pathogenes offer a 24-Hour turnaround time and the option of running multiple tests from a single sample.


Laboratory Testing

Pathogenes specializes in the bioassay of clinical samples.   Laboratory testing is an important part of case management and positively influences treatment decisions in cases of  neuromuscular diseases including EPM.

Our featured tests:

Enzyme-Linked Immunosorbent Assay (ELISA) Test

  •  SAG 1, 5, 6 ELISA's- Quantitative assay's that detect serotype antibodies to immunodominant surface antigens of Sarcocystis neurona in horses that have been infected or exposed to Sarcocystis neurona.


  • Sarcocystis fayeri antitoxin ELISA-Quantitative assay detects the presence of antitoxin, toxins are released from S. fayeri muscle cysts.  Sarcocystis fayeri is a common infection in horses.


  • MP2 ELISA- A quantitative assay that detects anti-myelin protein antibodies that are produced in autoimmune disease.


  • MPP ELISA- A quantitative assay that detects a neuritogenic peptide that is active in autoimmune neurodegenerative disease.


  • C-Reactive Protein (CRP) - A quantitative assay that measures inflammation due to protozoa, bacteria, or virus infections.


  • Sarcocystis neurona IFAT-A test to detect antibody against multiple antigens of S. neurona. This assay is used to qualify for our field studies.


  • Borrelia burgdorferi Assay-A quantitative screening bioassay to determine current infection due to B. burgdorferi.

How we help

It is our desire to help you manage your horse exhibiting signs of neurodegenerative disease. We collaborate with leading industry partners providing quality products that extend and significantly improve the well-being of animals. Testing accurately identifies animals with exposure or infection by S. neurona, the etiologic agent that causes EPM; S. fayeri, an overlooked cause of neuromuscular disease in horses; and polyneuritis, an autoimmune disease that is a result of chronic inflammation. Our goal is to deliver affordable testing, quality products, and reliable customer service. You can count on us to continue our research for the discovery and development of scientific techniques to enhance understanding of disease. We offer personal and professional development credit courses and certificate programs, which reflect and anticipate the changing nature of protozoal research.
