09 Dec Equine Piroplasmosis Testing Required for Kentucky Racetrack Entry – Effective 1 January 2011
Equine Piroplasmosis (“Piro”) testing protocols have been increased for horses heading to Kentucky’s Racetracks in 2011. This continues to be a disease that requires greater attention from all of us. Since October 2009 there have been approximately 550 horses throughout the United States found to be infected with the causative protozoan (predominantly T. equi but some B. caballi) that results in equine piroplasmosis being contracted. Though the vast majority of cases have been discovered in quarter horses, there is growing evidence the disease is present in the thoroughbred racing population as well. Because of limited testing having been conducted in this class of animal, the established prevalence continues to be an unknown. A map depicting the geographic distribution of horses tested and found to be positive during this period is attached for your information. The map was compiled from data provided by the USDA’s Veterinary Services. Additionally, equine piroplasmosis continues to be listed and described by the USDA as a Foreign Animal Disease.
