CHEYENNE, Wyo. (AP) — Wyoming State Veterinarian Jim Logan says a crippling disease has been found in more than a dozen race horses in Wyoming and they are under quarantine.

Officials say it is not a threat to the general horse population.

The animals have tested positive for equine piroplasmosis.

The American Association of Equine Practitioners says the tick-borne disease can cause fever, weight loss and swelling of the limbs. Treatment can take more than two years and some animals may have to be euthanized.
