• Research claims unique biological changes in mites living on dead facial skin.


• Researchers observed that these microorganisms are more adapted to human skin.


• According to experts, these mites can play a useful role in keeping skin pores clean.

You may not know but human on the skin There is always a reality of many microorganisms. These mysterious creatures are also known as mites or demodex folliculorum. These microorganisms hang upside down in the roots of your hair. You may be surprised to know that these microorganisms are born and die on human skin. Their whole life begins on our skin. They live by eating the dead skin on the skin. Meanwhile, it has been revealed in a new research that these microorganisms are changing rapidly and they are making different changes in themselves. Accordingly, they have now evolved from ectoparasites to fully obligate symbionts. Simply put, these organisms are slowly trying to assimilate into the human body.

In the new research, scientists performed deep sequencing of the genome of these microorganisms. But when the results of the research came out, it left the whole world stunned. Since they depend on humans, these microorganisms have undergone many changes. It contained some surprising changes in evolution that have never been revealed before. Alejandra Perotti, a leading researcher at the University of Reading, said: “These organisms have undergone a number of unusual changes in their DNA as they remain safely in the pores of the skin.” The structure of their body parts has also completely changed due to years of being safely in the facial pores.

How do these organisms reproduce?

• These mites cannot make the hormone melatonin in your body. In humans, this hormone helps regulate the nighttime sleep cycle. However, in small animals this hormone is essential for movement and reproduction.


• Although it is not a hormone, these organisms do not face any major problem. According to research, these microorganisms use the melatonin released by human skin at dusk.


• Unlike other organisms, the reproductive organs of these microorganisms are shifted to the anterior part of the body. The private parts of male mites are curved forward and upward from their back. Due to this, they have to maintain a certain position on the hair during mating.


• The role of reproduction is important for the survival and generation of the next generation of these microorganisms. However, according to research, their genetic diversity is continuously decreasing. Therefore, the possibility of new genetic changes is decreasing.


• According to the researchers, if this situation persists, it may seriously affect their evolutionary process in the future.

Are these microorganisms beneficial to humans?

Researchers have clarified the answer in their study. For many years, scientists around the world believed that these organisms did not have private parts for sperm. Until now, it was believed that feces accumulate in the body of these organisms and they die due to rupture due to this accumulated feces. This can cause skin problems in people. But a new study has completely disproved this old theory. These organisms actually have a small area to excrete feces. This means they don’t spread their feces on your face after they die. According to Henk Bragg, a noted zoologist at Bangor University, “mites are often blamed for various problems without any solid evidence.” He added that these microorganisms have a very old relationship with humans. Therefore, it cannot be ruled out that they may be doing some useful work for our body. In particular, they should play an important role in keeping the pores on the face clean.
