Prions, short for proteinaceous infectious particles, are misfolded proteins that carry the ability to trigger further proteins to misfold, leading to debilitating brain disorders, including:
- Bovine spongiform encephalopathy (BSE or mad cow disease).
- Creutzfeldt-Jakob disease(CJD), the human form of mad cow disease.
- Scrapie in sheep.
Prions are unique in being an infectious agent without any genes, unlike viruses or bacteria. They are extremely tenacious, sticking to metal surfaces of surgical instruments and surviving the high temperatures and chemical agents that kill off infectious viruses and microbes.
