Okla. Admin. Code § 35:15-11-51
Equine Piroplasmosis is a parasitic infection of horses, donkeys, mules, and zebras. It can be spread either naturally by ticks or through contaminated needles, syringes, dental equipment, and surgical equipment. These rules allow the State Veterinarian to issue interstate stop movement orders or quarantines of Equine Piroplasmosis reactors. In managing any premises that houses negative, positive, or reactor equids, exposing a negative equid to the blood or blood products of a positive or reactor equid shall be avoided. Proper handling of infected needles, surgical instruments, dental equipment, blood or blood products collected from positive or reactive equids, or other blood contaminated fomites, including blood contaminated semen collected for artificial insemination is essential, as Equine Piroplasmosis may also be transmitted through these routes.
