What is the most populous bacteria in all the world? An attending told me Staph Aureus, but this is generally on humans only right? In other words, if you took all the bacteria on earth, which species would have the greatest number?
 
Shouldn't it be that bacteria that fixes nitrogen for plant roots? mycorrhizzae something? I thought i learned that in gen bio....

My first inclination would be to go with the most abundant species in the ocean--like a cyanobacterium or P. marinus.

I don't think that it is S. aureus. On humans alone, you'd find more coag-negative staph. Pseudo is both a human pathogen and is very ubiquitos in the environment. B. subtilis is plentiful in soil.
