Immune systems arn't that good at detecting, much less combating, 'any'
non-self organism.  They are best at detecting and defeating things that the
organism routinly is attacked by.  Alien micro life would not be something
were 'tuned' to fight or look for.

Or never came here, or whiped out an area to quickly to sustain itself.

Still its unlikely to make us all run home and hide under the bed.  It never
did before when we encountered alien (foreign) cultures with magical
technologies and alien forms.  I can't see we'ld be that much less able to
handel the same thing now or in the future?

If it failed the real significant impact would have been international
relations and soviet vs U.S. world power.  But to people involved or
interested in the space program, it was a basic assumption that once the door
was opened we'ld stream out onto the new frounteir.  Didn't happen.

My point was the aliens wouldn't care about those effects.  If we can't play
nice with the new toys, thats our problem.

Send them the info via E-mail.  ;)  Besides to a galactic civilization, 5
billion is a few.

Anthropologists would tend to disagree.
