Prion strain adaptation : breaking and building species barriers
MetadataShow full item record
Prions have been an enigma to researchers and agricultural producers alike since their inception. The timing and order of prion disease discovery can be attributed to the scrutiny of the prion protein-only hypothesis. The characterization of bacteria, viruses, and the infectious qualities encoded by their genomes only confounded the hypothetical notion of protein as an infectious agent. Perhaps viral etiology theories could have been disregarded earlier if genetic prion diseases were not quickly overshadowed by experimental transmissibility of the putative infectious protein. Despite the ...
