The 'amazing' world of bacteria in the human body

A new study confirms the usefulness and importance of bacteria for the human body.

Learn what types of bacteria live in the human body

Many people still think that bacteria are 'uninvited' guests who enter the body and cause all sorts of troublesome illnesses. However, they actually account for up to 90% of living cells in the body (human intestinal tract alone contains up to 2kg of bacteria) and plays a very important role.

Dr. Roy D.Sleator, lecturer of Cork Institute of Technology, Kerry County, Ireland spent 4 years researching the topic of human interaction and bacteria to learn about the effects of they are for our body.

'Bacteria need to be considered as a true part of the body with much higher productivity than the liver.'

In the past, the role of natural bacteria was largely overlooked, but the latest analysis of DNA structure in the environment revealed the diversity and practicality of this microbial community. There are about 500 different species of bacteria in the human body. In an adult, the estimated number is about 100 trillion cells.

The number of parasitic germs that can be harmful to us can be said to be quite large but in general, most bacteria exist to be useful for our bodies, helping people stay healthy and longer. . The interaction between people and bacteria is a symbiotic relationship. They absorb food in our bodies but in turn help people produce vitamins, increase the ability to digest and enhance the immune system, helping to counteract the effects of 'bad' bacteria or dangerous pathogens. .

As we can see in nature, pets are often more susceptible to disease and have a much shorter lifespan than wild animals, even though they live in a much cleaner, safer environment. It is the most vivid proof for the important role of bacteria.
