... what kind of microbes?

Staph.

IIRC, one of the Apollos stripped an unmanned probe that had been there a while. The parts were found to have staph bacteria on them (surprise, surprise - "staph" is omnipresent on humans).

The scary part is that the bacteria was reactivated after all those years on the Moon.

I think NASA blamed the subcontractor on failing to properly (successfully?) sterilize the probe.

"staph"

Well, staph can get out of hand......(and into your eye, and under your skin, and into your blood, etc)

Wonder if there's anything else they're not telling us?
Secret cargo, perhaps?
