Virus Vs Bacteria, Difference Between Virus And Bacteria

What is a virus? What are bacteria?

The virus is a kind of non-cellular organism. It can insert into the human body like a needle, infect cells, and replicate genetic information. and then they use host cells to replicate themselves. CDC told us that wearing masks can effectively reduce the spread of the virus

Bacteria is a kind of single-celled organism. It lives with human beings. A bacterium is an individual. Its main structure is nucleosomes, without other organelles, but it can divide and reproduce by itself.

What Do Virus And Bacteria Have In Common

virus and bacteria are microbes and all alive, and some of them are deadly harmful to us

How to Distinguish Viruses From Bacteria? Several Differences Between Viruses and Bacteria

① Virus Vs Bacteria In Size, The Basic Difference

Viruses and bacteria differ in size, origin, and function in the human body.

Viruses are the smallest and simplest living organisms, much smaller than bacteria.

Bacteria are single-celled microorganisms, which can survive in other cells or without a host.

Viruses are intracellular organisms, and they need to invade other cells to survive. Viruses change the genetic material of the host and use the host to produce a large number of viruses.

② The difference between the two reproduction

Whether it is animal cells or plant cells, viruses must find a host cell to reproduce, and most bacteria can survive and reproduce independently without any host.

Bacteria have a set of apparatus (organelles) for growth and reproduction, usually asexual.

Instead, viruses usually package their genetic information, such as nucleic acids (DNA or RNA), in their shells. They need to use the host’s organelles to replicate themselves.

Their external “feet” attach to the cells and inject their genetic material into the cells. But the virus actually wrapped in the genetic material and it is not really a living virus. They had no sign of life until they met the host.

③ Is it good for mankind

Viruses and bacteria can also be distinguished in terms of their benefits to humans. Since the human body contains about 90% microbial cells and 10% human cells. It seems incredible that we have so many microbes in our bodies, but they are different individuals from our body cells.

Many bacteria coexist peacefully with the human body, Besides that,  many of them enhance the ability of the immune system to fight disease.

Moreover, they are responsible for very important tasks.  and well-known tasks are the production of vitamins, the treatment of negligible waste in the body, and the production of oxygen.

For example, under a microscope, scientists have discovered that most of the digestion process is carried out by intestinal flora. These bacteria also help maintain acid-base balance in the body.

As we know probiotics (such as intestinal flora) are the widespread presence in yogurt, such as bacteriophages.

Phages kill bacteria by phagocytizing their organelles. But most viruses are bad for people

Bacterial or Viral Infection

If you are sick, and you know what it is, you can do some background (search). Common diseases caused by bacteria infection and viruses infection include:
Virus Vs Bacteria
Bacterial infections including:

pneumonia, food poisoning, meningitis, septic laryngitis, gonorrhea.

Viral infections:

influenza, chickenpox, common colds, hepatitis B, SARS, measles, Ebola, HPV (human papillomavirus) infection, herpes, rabies, and HIV (AIDS) infection.

Sometimes the symptoms caused by viruses and bacteria may be the same, such as nausea, vomiting, sore throat, fever, fatigue, and general discomfort.

If you don’t know what’s wrong with you, it’s hard to know the cause by observing the symptoms.

whether the cause is a virus or a bacterium, the best way is to see a doctor and do some tests accordingly. The doctor will tell you what microbes are infected.
