First Detection of Chronic Wasting Disease in Moose (Alces alces) in Sweden

Abstract

We report the first detection of chronic wasting disease (CWD) in Sweden, in three old female moose (Alces alces). Prions (PrPCWD) were detected in brain but not in lymph nodes. The findings are similar to previously described CWD cases in old moose in Norway, where a spontaneous origin is hypothesized.
