1 There are some useful bacteria but all viruses are harmful. 2  Antibiotics cannot kill viruses, but can kill most bacteria, with the exception of most Gram-negative bacteria.  An example of a disease caused by bacteria is strep throat and an example of an affliction caused by a virus is the flu.

First of all, bacteria are much larger in size. The largest virus is only as big as the very smallest bacterium (singular for bacteria). But bacteria are still microscopic and cannot be seen with the naked eye.
