The Oregon State University College of Veterinary Medicine has diagnosed a horse with a form of equine herpes virus, a naturally occurring virus that can cause serious illness in horses. The horse is being treated for the neurotropic form of the virus, which is a mutated type of EHV-1 with a higher likelihood of causing neurologic disease. The horse in question is from the Coos Bay, Oregon, area and became acutely affected with weakness and staggering on Nov. 4. The animal is isolated at the Lois Bates Acheson Veterinary Teaching Hospital at the OSU College of Veterinary Medicine in Corvallis.
