In this article we will discuss about difference between virus and bacteria. The main difference is that bacteria are free living cells that can survive inside and outside the body, while viruses are abiotic collection of molecules that need a host to survive.

Virus
A virus is made up of a core of genetic material. Virus is a Noncellular, microscopic infectious.
Virus is an infectious agents that can only replicate within a host organism. Viruses can infect a variety of living organisms including bacteria and plants.
A virus lacks cellular material or strength to sustain by itself. Hence it can not replicate on its own outside the host cell it feed on.
History of Virus
The virus identification goes back to February 12,1982 and it is discovered despite limited technological intervention.
Dutch scientists, Martinus Beijerinck was firstly discovered of a virus in 1898.Beijerinck used a filtration experiment to show that a disease that infected tobacco plants was caused by something smaller than bacteria, which is called a virus.
Bacteria
Bacteria are microbes with a cell structure simpler than that of many other organisms.
Bacteria are found almost everywhere on earth. Bacteria are unicellular organisms.
Bacteria are single celled organisms that can be seen only with a microscope, the single celled or one celled organisms means each bacterium is made is made up only one cell.
History of Bacteria
In 1632-1723 antoni van Leeuwenhoek discovered a bacteria. Leeuwenhoek is universally acknowledge as the father of microbiology.
