1. Viruses are the smallest and simplest life form known. They are 10 to 100 times smaller than bacteria.
2. The biggest difference between viruses and bacteria is that viruses must have a living host - like a plant or animal - to multiply, while most bacteria can grow on non-living surfaces.
3. Bacteria are intercellular organisms(i.e. they live in-between cells); whereas viruses are intracellular organisms (they infiltrate
the host cell and live inside the cell). They change the host cell's
genetic material from its normal function to producing the virus itself.
4. There are some useful bacteria but all viruses are harmful.
5. Antibiotics can kill bacteria but not viruses.
6. An example of a disease caused by bacteria is strep throat and an example of an affliction caused by a virus is the flu.
