Donald P. Knowles, DVM, PhD, Dipl. ACVP, who devised and confirmed efficacy of imidocarb dipropionate as a treatment that eliminates Theileria equi from horses infected with equine piroplasmosis, is the inaugural recipient of the American Association of Equine Practitioners’ (AAEP) Research Award.

The AAEP Research Award recognizes an individual who has completed research that has or will make a significant impact on the diagnosis, treatment or prevention of equine disease. Knowles was honored Dec. 9 during the President’s Luncheon at the AAEP’s 60th Annual Convention, takind place Dec. 6-10 in Salt Lake City, Utah.

A 1982 graduate of the University of Illinois, Knowles is a professor in the Department of Microbiology and Pathology at the Washington State University College of Veterinary Medicine and research leader of the Animal Disease Research Unit of the United States Department of Agriculture. Since 2011, his research group has been included on six peer-reviewed publications related to equine piroplasmosis.

Following an outbreak of equine piroplasmosis on a Texas ranch in 2009, Knowles was involved with the emergency response to contain and eradicate the disease. As a result of this involvement, his research team helped to identify a new tick vector (Amblyomma cajennense) for equine piroplasmosis, developed a treatment to effectively eliminate one of the causative agents (T. equi) from infected horses, developed novel diagnostic techniques and characterized protozoal strains that could have previously eluded identification using existing diagnostic tests.

The results of this research will have a
