Understanding Viruses and Bacteria
Bacteria are single celled living organisms. They have a cell wall and all the components necessary to survive and reproduce, although some may derive energy from other sources.
Viruses are not considered to be "living" because they require a host cell to survive long-term, for energy, and to reproduce. Viruses consist of only one-piece of Genetic material and a Protein shell called a Capsid. They survive and reproduce by "hijacking" host cell, and using its Ribosomes to make new viral products. Viruses are tiny germs. They invade the normal cells to multiply and produce other viruses like themselves. This can kill, damage or change the cells and make body sick. Different viruses attack certain cells in the body such as : Liver, Blood, Respiratory system. Viral infections are a symptom of weak immune system which is dependent on Gut health.
Less than 1% of Bacteria cause disease. Most are beneficial for good health and health of ecosystems. Most Viruses cause disease. Antibiotics may be used to treat some Bacterial infections but they do not work against Viruses.
As mentioned, Viruses consist of Genetic material, such as DNA or RNA (but not both) surrounded by a protein shell called Capsid. Sometimes, this shell is surrounded by an envelope of fat and proteins molecules, and out of this envelope may project Glycoprotein protrusions called Peplomers which can be triangular, spike or like a mushroom. These protrusions bind only to certain receptors and determine what type of hosts or host a virus will infect and how infectious that virus will be. A microscope is required to see viruses and they are 10 to 100 times smaller than the smallest Bacteria.
Viruses must infect host cell to carry out life sustaining functions or to reproduce, they are not considered living organism, although some can survive on surfaces for long periods. Viruses are essentially like a parasite, relying on a host cell to reproduce and survive.
Viruses are smaller than Bacteria and can't reproduce without the assistance of a Host. Bacteria are capable of reproducing on their own.
When Virus infects a Host cell, it uses its Genetic material to "Hijack" the Ribosomes in the host
cell.These are the cell structures that make Protein. So instead of Protein being made that can be
used by the host cell, Viral Proteins are made. The viral also takes advantage of other components within the host cell such as ATP ( Adenosine Triphosphate) for energy and Amino acids and fats to make new Capsids and assemble new viruses. Once enough new viruses are made, they burst out of the cell in a process called Lysis, which kills the host cell. This is called viral replication and it is the way Viruses reproduce. Once new viruses have been made, they can go on to effect new host cells and new hosts.
Bacteria and Viruses can be spread in similar ways such as in some infections, like Pneumonia and Diarrhea, it's difficult to determine whether it was caused by Bacteria or Virus and testing may be required.
