Your asuming they have an evolved defence against the intruders (unlikly) and
that the bacteria themselves might not be the food for the intruder.  Even
tiny samples of more toxic bacteria introduced into a filled culture, will
whip out the rest of the stuff in the culture.

There are.  The ones merntioned above handel frezing to hundreds of degrees
water just fine.  They can survive far worse.

Many unnatural substances can be introduced without reactino.  the deseases
that kill us specifically are ones te body often does not react to effectivly
or at all.

Poisons can work quickly or take years.  They are just chemical componds.  If
the body doesn't normally break them down and excreat them safely, we get
