- Transmissible
Spongiform Encephalopathy (TSE): A family of progressive,
incurable, fatal diseases caused by prions. Characterized
by dementia, and holes in the brain on autopsy. Can
be transmitted between mammals when one mammal eats
parts of the nervous system (e.g., brain, spinal cord)
of another mammal.
- Prion:
Prion: (pronounced pree-on) Novel infectious agent common
to these diseases. Not a virus or bacterium, but an
infectious protein which can set off a chain reaction
which destroys nerve cells. They cannot be inactivated
by most sterilization methods.
- Bovine
Spongiform Encephalopathy (BSE): The technical name
for Mad Cow Disease - the TSE found in cattle. The form
of BSE found in European cattle is probably not the
same as that in US cattle.
- Creutzfeldt-Jakob
Disease (CJD): A human TSE. The classic form of
CJD appears to arise spontaneously, but the so-called
"new variant" of CJD (nvCJD) is now known
to be the human equivalent of mad cow disease thought
to be contracted by eating contaminated beef.
- Kuru:
Another human TSE, found in Pacific Islanders who ate
human brains.
- Scrapie:
The TSE found in sheep. The probable source of all other
animal TSEs.
- Downer
cow: US industry term for an animal who falls down
and dies without an apparent disease. Some people speculate
that some US downer cows have a form of BSE with different
symptoms from the British form of BSE.
