About Us and our Mission

Pathogenes is a small research laboratory with large ideas, located in Fairfield, Florida.  We test samples, analyze data, and invent tools to diagnose and treat horses with neurodegenerative diseases including EPM, equine protozoal myeloencephalitis.  You can read about our work, Learn More, or call us at 352-591-3221 and speak to any member of our team. We have Zoom meetings that can be scheduled upon request, discuss your case or new research that can help you with your case.

samples are set up when they come in, giving you same 

day service.

And of course, there's our resident PHD, Siobhan Ellison. 



In the US, many animal species do not have drugs specifically labeled for them. To ensure their welfare is protected and diseases can be successfully treated MUMS attempts to create an FDA controlled process by which effective treatments are produced. MUMS offers incentives to manufacturers that produce drugs for rare diseases.

If the phone is unresonsive, use the cell or email to get
hold of us. The utilities in the country can be sketchy.
