Bacteria are living organisms made up of a single cell, which is very small where they are seen only using a microscope. Bacteria are either bronchial, circular or clustered. The bacteria are self-sufficient, ie, they do not require a host to multiply, and they multiply by dividing.
Bacteria have been one of the earliest lifestyles on Earth and have evolved to resist various environmental conditions. Some bacteria can tolerate high temperatures or severe cold, and other species live even when exposed to levels of radiation that are fatal to humans. However, most bacteria are suitable for the medium environment in a healthy body.
Some bacteria are harmless, and these live on human skin or in the mouth or intestines and elsewhere, but that the existence of some of these species is necessary until human beings,
It helps digest food and distinguishes inflammatory organisms from the human body. But when harmful bacteria enter the human body, they can cause the disease. These bacteria multiply rapidly, and many of them produce toxins, powerful chemicals that destroy certain cells in the tissues that attack them, which makes a person sick.
Unlike viruses that also cause infections, bacterial infections can be treated with antibiotics that kill bacteria and hinder their growth and reproduction.
