1. Equine Piroplasmosis: Emerging Threat to the Horse Industry Lauren Lewis1 and Pete D. Teel2 Department of Entomology, Texas A&M University, College Station, Texas 1Senior Biomedical Science and Entomology Double major, 2Professor and Associate Department Head 1
2. 2 Equine Piroplasmosis (EP) : Acute tick-borne disease of Equids (horses, mules, donkeys, and zebras) >50% mortality in naïve animals Difficult to diagnose Recent increase in serologically positive US horses Effects breeding, working, and performance horses Major constraint to interstate and international movement of horses
8. Endemic in many tropical and subtropical regions including parts of Africa, the Middle East, Asia, Central and South America, the Caribbean and Europe
21. 6 Negative Effects of EP: Travel Restrictions Mandatory Serological Testing Quarantine Loss of non endemic status
22. 7 Diagnosis: Clinical Signs Variable and nonspecific EP should be suspected in horses with anemia, jaundice and fever T. equicauses more severe disease than B. caballi Incubation period is 12 to 19 days when caused by T. equiand 10 to 30 days when caused by B. caballi EP is a reportable disease; suspect cases should be reported to state & federal authorities
23. 8 Prevention and Control Prevention with acaricide applications to animals prior to exposure, and post-exposure if needed Vegetation free zones Avoidance of Tick infested areas Post exposure tick checks Pre-purchase evaluations & testing
