PRIOR LAKE, Minn. (AP) - One of two horses that contracted a contagious virus at a Prior Lake farm has been put down. The other was taken to the University of Minnesota's Large Animal Clinic for treatment.

Minnesota Board of Animal Health assistant director Paul Anderson says the equine herpes virus cases were found at Dark Horse Farms. Anderson tells reporters the stable owner reported the illness and reached out to area veterinary hospitals.

Last spring, 14 horses in Minnesota were diagnosed with the virus which causes neurological problems. At least three horses were euthanized. It also limited the number of horses in the annual Minnesota Horse Expo at the state fairgrounds in St. Paul.
