This entry is part 1 of 2 in the series 2024 Series on EPM

What is EPM?

EPM is a parasitic infection of the central nervous system caused by a single-celled microscopic organism called a protozoa (protozoa are not worms and are not killed by worming). The protozoa associated with most EPM infections appears to be Sarcocystis Neurona (S. neurona). Other protozoa also may be involved, including Neospora Hughesi (N. hughesi).
