How do we usually see it, if we ever see it? Usually in animals - primarily sheep or cattle. One of the first things you learn in infectious disease class in veterinary school is "if you are called out to post (autopsy) a dead cow and she has blood coming out her orifices (sorry)do NOT open her up right there in the field without getting a complete history and eliminating other causes of death. If you are unlucky enough to post her anyway and you find a 'blackberry jelly spleen,' you are in deep sh*t."
Does this mean we should all be apopletic over this - we shouldn't, just yet. However, the CDC and FBI should be and they are, so hold onto your undies and don't get 'em in a wad just yet.

I beg your pardon? Mine are never in a wad....I find that disgusting.
