Chronic Wasting Disease Test Developed by Scientists

BILLINGS — Scientists have developed a new way to test live animals for chronic wasting disease that holds promise for one day detecting the illness in the wild.

“We need to do more in the form of field testing to verify its utility,” said Byron Caughey, chief of the TSE/Prion Biochemistry Section at the National Institute of Allergy and Infectious Diseases in Hamilton.

The new method utilizes a piece of tissue from the animal’s ear for testing. Previously, more invasive tests had proven effective but difficult to collect, including a rectal sample or biopsy of lymph nodes.
