Space-dwelling microbe
A space-dwelling microbe was a microbe which resided in outer space.

By 2151, Polycocyx astris was one of over two hundred million space-dwelling microbes that had been cataloged. It resided inside grains of interstellar dust and was one of the most virulent species, which could drift in a dormant state for millions of years and still cause a cold. ()
