Creutzfeldt-Jakob disease in humans and scrapie in small ruminants are the longest known diseases in this group, but prion diseases entered the public spotlight with the massive bovine spongiform encephalopathy (BSE) epidemic started in 1986 in the United Kingdom, revealing the zoonotic potential of animal prions.
HCC believes it has overcome the main potential stumbling block for imports of EU lamb - the existence of TSEs which manifests itself as scrapie in sheep.
In humans, they comprise Creutzfeldt-Jakob disease (CJD), fatal familial insomnia (FFI), kuru, Gerstmann-Straussler-Scheinker disease (GSS), and the recently described variably protease-sensitive prionopathy (VPSPr), whereas natural TSEs in animals include scrapie of sheep and goats, bovine spongiform encephalopathy (BSE), and chronic wasting disease (CWD) in deer and elk.
Classical scrapie strain, for example, can be distinguished from more sensitive atypical scrapie strain based on the difference in resistance to low and high concentrations of PK [20].
(P1NKSHEETS: MEDS) said on December 13 that its CEO Thomas Ichim co-authored a research project using MRI to assess brain changes in sheep infected with scrapie (the sheep form of mad cow disease) before symptoms of the fatal brain disease appear.
