Texas Horses Confirmed Positive with EIA – and EP
Smith County, Texas
February 13, 2019
Texas authorities confirm nine horses located on a Smith County property are positive for equine infectious anemia (EIA).
Officials from the Texas Animal Health Commission (TAHC) state seven of the EIA positive “racing Quarter Horses” and another horse on-site tested positive for a secondary infectious disease called equine piroplasmosis (EP).
EP is a tick-borne disease that affects horses, donkey, mules, and zebras. Specifically, its caused by the protozoa Babesia caballi or Theileria equi.
Although several species of ticks in the United States are capable of spreading the parasitic disease, experts state, “the spread of EP through ticks has only been seen in isolated areas in South Texas.” Other transmission methods include blood transfusions, contaminated needles, syringes, and even dental floats.
Equine piroplasmosis cases can be mild or acute. Symptoms in an acutely affected equine may include fever, anemia, jaundiced mucous membranes, swollen abdomen, and labored breathing. EP can also cause a roughened hair coat, constipation, and colic.
Horse owners can choose to treat their EP positive horse although there is no guarantee of clearance, according to TAHC. Until that time, EP horses must remain quarantined. They are microchipped with an ISO 11784/11785 compliant microchip and another acceptable form of identification such as a tattoo.
For the EIA positive horses, they must remain under a lifelong quarantine or face euthanasia.
The state implemented a quarantine of the premises.
