One of the major disparities between bacteria and viruses is the host. A bacteria cell is able to grow on both non-living and living surfaces, whereas a virus must have a living host, such as animal or plant.
Bacteria cells possess the cell organelles required for their multiplication as well as growth, they typically reproduce asexually by the process of binary fusion (McComas, 1998). Viruses contain genetic material (RNA or DNA) that are packed in a membranous protein coat, unlike bacteria viruses utilize the host cell during their reproductive process.
A virus makes contact with an individual cell. It inserts RNA or DNA materials in the host cell, thereby undergoing lytic and lysogenic phases respectively. These phases lead to the production of numerous viruses within the host cell, thus killing it (Ahrcanum Word Press, 2009).
