The human body contains a large quantity of many different microbes, which play a fundamental role when it comes to human health.

Even though microbes have a negative effect on the body, it also has benefits and can help combat diseases and bad levels of bacteria, when studied and configured and treated accordingly. It is all thanks to microbiologists.

Microbes exist in the human body, as well as play a very significant role in the health of humans.

When it comes to specifying microbes, every individual has a variety of different microbes within their bodies. It can be found everywhere from the skin, oral and nasal cavity, reproductive organs and the gut.

Microbes can be either commensal or mutualistic. Commensal microbes are often found in humans, while mutualistic ones are found in relation to the host.

The interactions of microbes in the body allow humans to maintain their health, as well as grow effectively.

The Roles of Microbes to Aid in Health


To stay healthy, humans need microbes to survive. There are approximately 100 trillion cells in the average human’s body, but that doesn’t mean they are human cells whatsoever.

These cells consist of viruses, fungi and other organisms which are specified as microbes. Human microbiomes are a point of genetic diversity, where two human microbiomes, on the other hand, are the source of genetic diversity.

Microbiomes play a very important role in the human body and are essential for maintaining a healthy immune system. It can also best be described as a functional entity, which has a more significant effect on the metabolism and overall, aids in the maintenance of the human body’s health.

Microbes Overview

Microbes are considerably the oldest form of life that has been found on earth and have been around for 3.5 billion years.

According to scientific research, these microbes have even developed with humans over the past six million years and continues to change over time to this very day.

Microbes are needed in the body to ensure it stays healthy. When it comes to the human host, as well as its microbial flora, it creates a complex ecosystem that acts as an example of reciprocal adaption.

Microbes have been responsible for the resistance to colonisation within the body, by means of exogenous pathogenic organisms and when in contact with the host, is responsible for infections caused in our immune system daily. These are responsible for flu, colds and severe infections in the human body.

Since microbes have a larger effect on the skin, gut, reproductive organs and nasal, as well as oral cavity, it is understandable why it aids in fighting infections in bacteria, overall protecting our immune system. It is necessary to maintain proper health in all the points of our body, which exterior microbes meet interior microbes.
