Virus And Bacteria

A virus needs a host body to survive and thrive while bacteria do not need a host body to survive. What are some other differences between a virus and bacteria.

Bacteria Versus Viruses Infection Control Nursing Medical Knowledge Medical Laboratory Science

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.

Virus and bacteria. Bacteria can sometimes cause infectious disease too. Whereas viruses are intracellular organisms they infiltrate the host cell and live inside the cell. They live in between cells.

Bacteria can live in almost every conceivable environment including in or on the human body. By contrast the smallest bacteria are about 400 nanometres in size. Bacteria are intercellular organisms i e.

Bacteria on the other hand are living organisms that consist of single cell that can generate energy make its own food move and reproduce typically by binary fission. They range in size from about 20 to 400 nanometers in diameter 1 nanometer 10 9 meters. The biggest viruses are only as large as the tiniest bacteria viruses are microscopic.

The size of the bacterium is larger than the virus. Some bacteria are healthy. All types of viruses can cause disease while all bacteria do not cause disease.

For this reason they are considered living organisms as they have in place various cellular mechanisms that allow them to grow and reproduce. As compared to viruses bacteria contain a few organelles that perform different functions which allow the organisms to obtain energy from their surrounding grow and reproduce. O another difference is their structure.

Viruses are not living organisms bacteria are. Viruses require the aid of a living cell in order to reproduce. Viruses also may contain an attachment structure that allows them to attach to the surface of the host cell.

Their life therefore requires the hijacking of the biochemical activities of a living cell. These bacteria are referred to as pathogenic. This allows bacteria to live in many places.

Viruses only grow and reproduce inside of the host cells they infect. Some fungi and algae can be pathogenic too. Bacteria are single celled organisms that reproduce asexually independently of other organisms.

Only a handful of bacteria cause infections in humans. Although bacteria and viruses are both too small to be seen without a microscope they re as different as giraffes and goldfish. Five distinct features differentiate between the virus and the bacteria.

Bacteria are relatively complex single celled creatures many with. Viruses are smaller in size than bacteria. As we noted in the intro a pathogen is an agent that can cause a disease especially a virus or bacterium.

Bacteria are complex compared to viruses. Viruses cause infection and those infections very often result in disease. Viruses are about 1 000 times smaller than bacteria and are visible under an electron microscope.

When found outside of these living cells viruses are dormant.
