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.
Recognize the differences in reproduction. Viruses must have a living host to multiply, such as a plant or animal. Meanwhile, most bacteria can grow on non-living surfaces. 1  Bacteria have all the machinery (cell organelles) needed for their growth and multiplication and usually reproduce asexually. Both bacteria and viruses can cause nausea, vomiting, elevated temperatures, fatigue, and general malaise. 2  The best (and sometimes only) way to determine whether you have a bacterial or viral infection is to see your doctor. 3  Your doctor will perform lab tests to determine what kind of infection you have.
