Differences Between Bacteria and Viruses


What is the bacteria?
Bacteria are microbes that belong to the Prokaryoter family. Bacteria have a thin but it is hard cell wall, and the rubbery membrane protects the fluid inside the cell. Bacteria can be multiply on their own, it is mentioned by division. The issues of fossil research state that bacteria have remained since 3.5 billion years ago.

Bacteria can live in a variety of environmental conditions, they include extreme environments , such as extremely hot or highly cold environments, in environments that consist of radioactivity and there is in human body.

Most bacteria do not cause disease, except...

Actually, there is only less than 1% of the types of bacteria that can cause the disease. Most bacteria are absolutely helpful, such as supporting to assimilate food, protect other microbes that generate the disease, protect from cancer cells, and provide good nutrients.

The diseases are caused by bacterial infections that include:
  • Sore throat
  • Tuberculosis
  • Urinary tract infection
  • Diphtheria, and others

What is virus?
Viruses are microbes that cannot stay without adding to their group. New viruses can be multiply when they attached to other living things. The size of virus is also much smaller that bacteria. Every virus has genetic material, either RNA and DNA. Usually, the virus will stick to a call and take over the cell to propagate other viruses until the cell dies. In other cases, the virus reorganizes the normal cells that are bad for our health.

Most viruses can cause the disease
Inversely related to bacteria, most viruses cause disease. Viruses are also "picky", such as specifically attacking certain cells. For example, certain viruses attack in the pancreas, respiratory system, and blood. In certain cases, the virus also attacks bacteria.

Diseases are caused by viral infections include:
  • Chicken pox
  • AIDS
  • Flu
  • Polio, and others

The signs of contracting a viral and bacterial infection

You have to discuss with your doctor to determine about your disease, whether it is a bacterial or virus infection. Usually, the doctor will listen to the signs that you feel, see your medical history, and check for physical signs.

Symptoms of a bacterial infection
Here are the signs that often appear in bacterial infections:
  • Slimy nose
  • Fever
  • Sometimes Coughing
  • Sore throat
  • Earache
  • Hard to breathe

Symptoms of a viral infection
Here are the signs that often appear in a viral infections:
  • Runny nose
  • Sometimes nosebleeds
  • Sometimes fever
  • Coughs
  • Sore throat (but it rarely happens)
  • Insomnia

The duration of the virus infection signs usually occurs briefly but it is acute, whereas the signs of bacterial infection usually occur for 10 to 14 days continuously.

If it is necessary, the doctors usually will ask for a blood urine test to confirm the diagnosis, or it does a culture test to identify the type of bacteria or virus that has infected you.
