Bacteria belong to the most wide-spread of organisms; we may say 

 they are omnipresent; they never fail either in air or water; they at- 

 tach themselves to the surface of all firm bodies, but develop in masses 

 only where decomposition, corruption, fermentation or putrefaction 

 are present. (Ferdinand Cohn, transl. by C. S. Dolley).
