Shoestring, loved by everyone that knew him. Can EPM be prevented with drugs? What are the unintended consequences of continued antiprotozoal therapy? These are complex questions without simple answers. Equine protozoal myeloencephalitis is a syndrome that involves infection with pathogenic protozoa and, in some horses, the infection can cause neuroinflammation. [...]

Yes, you can understand Equine protozoal myeloencephalitis! We have looked at over 12,000 suspect cases and found meaningful patterns. Remember that EPM is a syndrome that involves infection with Sarcocystis neurona and the inflammation that results from infection. Sure, ataxia can accompany other diseases that may look [...]
