A 22-month-old, female red deer (Cervus elaphus) was submitted to the University of Minnesota Veterinary Diagnostic Laboratory for necropsy and chronic wasting disease (CWD) testing. The deer was found positive for the abnormal prion protein in the obex and the retropharyngeal lymph node by immunohistochemical staining. Microscopic lesions of spongiform encephalopathy and immunohistochemical staining patterns and intensity were similar to those in CWD-positive elk and experimentally infected red deer.
