You posted some interesting food for thought. E. zaire and E. reston could recombine naturally, and form one nasty murderous bug. On the other hand, someone with just the right kind of knowledge could create such a virus, with common genetic recombination techniques.

To put it another way, as I explained to my husband recently, I am a very dangerous person because of what's in my head. (So are most of the people I know.) I choose to use my knowledge in a way that will advance science and humankind; what could a truly evil person (e.g. a terroristic dictator) do with the same knowledge?

Viruses and Bacteria can not combine naturally from two strains...they are both asexual and reproduce from internal processes with no external contribution. Now...man made, that's a different story.
