Another explanation would be that as I suggested: Contamination won't
happen unless you are contaminating with large numbers of bacteria.
And what about those typical totally grey-skin with large black eyed aliens
that every selfrespecting abductee tells about. Couldn't that grey skin not
just be a "space"suit? If these aliens breathe oxigen, then they would
hardly need anything more than a water-tight suit to survive in Earth's
atmosphere. (So no cumbersome backpacks nor metal parts to avoid the
spacesuit from becoming a balloon.

Our body can become very agressive, it will change environmental parameters
of which the best known is temperature. This will reduce the growth rate of
the alien cells while our body has a wealth of options to partially
compensate for this thermal inconveniance.
Furthermore leukocytes (attack cells) will attack and won't make feeding
for the bacteria or small organisms any easier.
In fact our body can destroy part of itself in a fight: High fever can
cause serious damage to organs, the high temperature is generated by the
body itself in response to the intruder.
