The word you are looking for is "prion", not "preon" http://en.wikipedia.org/wiki/Prion.
BSE is a prion. http://en.wikipedia.org/wiki/Mad_cow
Chronic Wasting disease is possibly a prion http://en.wikipedia.org/wiki/Chronic_wasting_disease
But AIDS is a retrovirus http://en.wikipedia.org/wiki/Mad_cow
One thing the three diseases have in common, though, is that they aren't "alive" and only function
at all within a living organism-- and one with similar proteins to which the diseases are adapted.
Retrovirii are closer to living (yep, there are degrees to "not alive") than prions, but even HIV
dies very quickly when removed from a living host. So those examples would be about the longest
shots imaginable for making it on another planet.
