A Prion Protein Gene Polymorphism at Codon 138 Modulates Chronic Wasting Disease Pathogenesis ...
Prion diseases are fatal and infectious neurodegenerative diseases caused by prions. Chronic wasting disease (CWD) is a prion disease of cervids found in North America (NA), Scandinavia and South Korea. Although there are no reports of CWD in caribou (Rangifer tarandus spp.) in NA so far, previous f...
