Description. Equine piroplasmosis (EP) is an infectious, noncontagious, tick-borne disease of horses and other Equidae (donkeys, mules, and zebras). It is caused by either of two protozoan parasites, Babesia caballi or Theilaeria equi. They are transmitted primarily by ticks. Horses that recover from EP remain as carriers without displaying any signs of infection and can act as reservoirs for transmission of the pathogens by ticks.
