Moon Landing Could Have Infected the Earth With Lunar Germs, Say Astronauts (independent.co.uk) 180
PolygamousRanchKid quotes a report from The Independent: A mistake made during the Apollo 11 moon landing could have brought lunar germs to the Earth, astronauts have revealed. When the three astronauts flew to the Moon and back, exactly 50 years ago this month, NASA worked hard to ensure that no bugs were brought back from the lunar surface. All three of the Apollo 11 crew were put into special clothes, scrubbed down and taken to a quarantine facility where they lived until scientists could be sure the Earth would not be contaminated. But interviews from a new documentary -- filmed by PBS and revealed by Space.com -- show that the plan to keep Earth could easily have failed, and that space bugs could have got into the Earth's atmosphere despite Nasa's best efforts. The astronauts noted that Nasa did not think there would be anything alive on the Moon that could be brought back down to the Earth. But the precautions were taken in case there were. "Look at it this way," astronaut Michael Collins said. "Suppose there were germs on the moon. There are germs on the moon, we come back, the command module is full of lunar germs. The command module lands in the Pacific Ocean, and what do they do? Open the hatch. You got to open the hatch! All the damn germs come out!"

There may be bacteria on earth capable of colonizing other bodies in space. In fact, bacteria exists on the outside of the ISS and other satellites, so, there might be some that can survive elsewhere.
HOWEVER, earth and the moon have regulary exchanged substrate over the eons. Asteroids have caused exchange of rocks.

Just a couple of points:
One, the helium on the moon is in the rocks, and extractable through mining not breathing.
One point five, the moon does not have any atmosphere to breathe anyways.
And two, there is no rationale in a creature that breathes helium because helium is too nonreactive, and the energies it requires to get it to react with something as might be required for a biological process like breathing would probably be detrimental to the life of any creature that tried to breathe it.

By that logic, why do invasive species exist?

The reason that terrestrial germs are dangerous to humans is that they've spent millions of years evolving to attack animal immune systems.
