Prion proteins and prion diseases
The so called prion diseases (for more details see ) result in destruction of the brain, this is eventually fatal. The first such disease described (in the 18th century) was scrapie in sheeps. It was noted that this disease could be spread to other animal species by feeding them infected brain. One of the most remarkable features of the infectious agent of scrapie is its incredible resistance to destruction. A sheep head, buried for three years, proved still infectious when fed to mice. The agent can not be inactivated with formalin (methanal), with UV light or by heat sterilisation.
