What diseases can a CT scan detect? A bowel perforation consists of a hole that runs all the way through the bowel or large intestine. The danger is that perforation can cause peritonitis, an inflammation of the membrane lining the entire abdominal cavity. If acid from the stomach, bile or bacteria enters the cavity, then peritonitis can take place -- a life-threatening condition.
The statement that a prion is an infectious, self-reproducing protein structure is true. Prion is short for short for proteinaceous infectious particle. All known prion diseases in mammals affect the structure of the brain or other neural tissue. Hope this answers the question. Comments.
Prions are abnormal forms of the protein PrP; they transmit several diseases that affect neural tissues in animals and humans. Viroids differ from viruses in that they lack a protein coat; they are merely circular, single-stranded RNA fragments that replicate on their own inside plant cells.iroids do not cause disease processes in humans or animals; their effects are limited to plants. However, a similar infectious agent, a virusoid, causes type D hepatitis, an exceptionally virulent form of that disease.
