Mad cow DNA may offer clues to latest U.S. case
US - DNA from the brain of an aged beef animal could show why there were conflicting results from U.S. mad cow tests and if the disease arose spontaneously, a British expert told Reuters on Friday. Danny Matthews, head of the research and surveillance program for transmissible spongiform encephalopathy at the Veterinary Laboratories Agency in Weybridge, said British scientists have done similar DNA analyzes on other animals.Source: Reuters
