What causes Creutzfeldt-Jakob disease?

Answer:
The causative agent of Creutzfeldt-Jakob disease is the CJD prion (proteinaceous infectous particle). It is neither virus, bacteria, protozoan or fungi. In fact, it is not living. It is a mutated protein, an unfolded alpha-helix into a beta-pleated sheet.
