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 extremely small, smaller than viruses, and even through an electron microscope only aggregations (clusters), not individual prions, can be seen. Prions are unique pathogens in that they appear to have no nucleic acid and thereby differ from viruses, bacteria, fungi and other pathogens. Prions are resistant to procedures that break down nucleic acid and destroy biological forms of pathogens.
