This is why most domestic born horses (which Nasi is) don't suffer
from SE. They develop immunities from birth and imports don't have
that opportunity. I think the young age exposure is the key but I'm
no scientist so this is just my take on what I've read.

You are absolutely correct about the immunology, Laree! Most
any agent that an animal is exposed to in utero or shortly after
birth (when his immune system is getting programmed) is later
recognized as what is called "self"; it thus does not normally elicit
an immune reaction (except in cases of auto-immune diseases, of
course). As you correctly say, that is why only few domestic-born
horses develop SE (and generally those were born in very arid or far
Northern areas, where there is little exposure to culicoides).
If you are interested in this, you can read a quick summary in my
two Eidfaxi articles on SE (available at < http://iceryder.net/
se.html > ).
