1 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. 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). 2  They change the host cell's genetic material from its normal function to producing the virus itself.
