A bacterial cell is a single-celled organism, but a virus is just a protein wall containing DNA or RNA, which it injects into the nucleus of a cell to cause it to start replicating the virus's NA rather than the cell's own. Bacteria are large enough to be seen with optical microscopes, but virus's are so small they weren't discovered until electron microscopes came along. Bacteria are alive and virus's are not. Bacteria can be killed and therefor cured. Virus's live in the blood and they can be treated but not cured and it could always show itself again. bacteria are cellular form of life, bacteria can be good or bad. Good bacteria in intestines which help digestion, bad bacteria such as pathogens are able to reproduce on their own. Virus's are pathogenic, virus's are not cells, and they reproduce by taking over cells.
