Citaat:Dr. Valentine writes that EPSM "has been confirmed or suspected in virtually every draft horse breed, including Belgian, Percheron, Clydesdale, Shire, Haflinger, Norwegian Fjord, Irish Draught, Friesian, Gypsy Vanner, draft cross, and a draft mule. This newly-recognized disease, under research at the College of Veterinary Medicine at Oregon State University, has likely been around for hundreds of years."
