Equine parasitology is the study of parasites and their interaction with the horse and other equines. It involves the study of protozoa, such as Sarcocystis neurona, which causes equine protozoal Myeloencephalitis (EPM), helminths (worms) such as roundworms, and arthropods such as the tick, Ixodes scapularis, that transmits Lyme disease.

Anthelminitic resistance, or resistance of worms to equine dewormers, is an important issue in equine parasitology and is a growing problem worldwide. No new medications are being produced to combat intestinal parasitism therefore we must research better ways to manage our horses.
