Is it conceivable that there are human-borne organisms now living on the moon?

I've read about bacteria being able to survive vacuums and some are able to persist as memnospores.

So is it possible that on our missions to the moon, we transported organisms to the moon that are, in some way, 
still alive? What sort of organisms would we be likely to find?

How about Mars? Could some have come off the rovers sent there?

I recall Apollo 12 recovering the remains of the Surveyor 3 probe and finding that a small colony of bacteria that had been placed in it had survived 3 years on the moon. So yeah, they can survive, apparently. For 40 years? We won't find out until we go back.
