Ectoparasites on a horse
Several of these organisms were recovered from a Quarter horse in New Jersey. What are they and what pathogens do they transmit?
These are Ixodes scapularis, the deer tick or black-legged tick. Adult deer ticks are commonly found on horses, particularly in the colder months, and in areas where disease is endemic, these ticks may transmit Borrelia burgdorferi and Anaplasma phagocytophilum to horses.
