>>There are antiserums raised from animals against tetanus and snakebite
that are farther removed from humans than primates: horses, goats,
sheep to name a few. It is my understanding that such antibody preparations
can be purified by running the material through an affinity column.
Recently a company in Wisconsin has sucessfully made anti-sera against
snake venoms from chicken eggs by injecting the hens with non-lethal
doses of snake venom and recovering the antibodies from the eggs.
The real unbelievable part of the film Outbreak, which started this
conversation, was Dustin's Hoffman's (aka Dr Daniels) luck in finding a
single escaped cotton-topped marmoset running around the woods of
Northern California. Of course it helped that he had a virologist
with him that knew how to fly a chopper and could outfly the army's most
experienced fighter pilots who were trying to bring them down. Top that
off with getting sucessfully back to a mobile field lab in the middle
of the town where the epidemic was occuring and manufacturing in a few hours
enough serum to cure the entire town! Boy thats what I call unbelievable.
Makes you proud don't it?
