Bacteria VS Virus

In our daily routine, most of the time we ignore little safeties required for our health, these types of habits spread different types of diseases. Researchers work day and night to produce strong and helpful medicines to protect us from different health issues. Some diseases are known as virus and objects involve to spread these diseases are known as bacteria. In this versus we are going to discuss about Bacteria and Virus.

Bacteria

Introduction (from Wikipedia):
Bacteria constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals.
Ribosomes:
Present
Cell wall:
Peptidoglycan / Lipopolysaccharide
Living attributes:
Living organism
Nucleus:
No
Number of cells:
Unicellular; one cell
Structures:
DNA and RNA floating freely in cytoplasm. Has cell wall and cell membrane.
Reproduction:
Fission- a form of asexual reproduction
Treatment:
Antibiotics
Enzymes:
Yes
Virulence:
Yes
Infection:
Localized
Benefits:
Some bacteria are beneficial (e.g. certain bacteria are required in the gut)
Size:
Larger (1000nm)

Virus

Introduction (from Wikipedia):
A virus is a small infectious agent that replicates only inside the living cells of other organisms
Ribosomes:
Absent
Cell wall:
No cell wall. Protein coat present instead.
Living attributes:
Opinions differ on whether viruses are a form of life or organic structures that interact with living organisms
Nucleus:
No
Number of cells:
No cells; not living
Structures:
DNA or RNA enclosed inside a coat of protein
Reproduction:
Invades a host cell and takes over the cell causing it to make copies of the viral DNA/RNA. Destroys the host cell releasing new viruses.
Treatment:
Vaccines prevent the spread and antiviral medications help to slow reproduction but can not stop it completely
Enzymes:
Yes, in some
Virulence:
Yes
Infection:
Systemic
Benefits:
Viruses are not beneficial. However, a particular virus may be able to destroy brain tumors (see references). Viruses can be useful in genetic engineering.
Size:
Smaller (20 - 400nm)
