Scientists from the University of California told why bacteria and viruses can not escape

No matter how carefully we treat hygiene, no matter how thoroughly we wash, each part of our body will still be covered with different microorganisms: bacteria, viruses, fungi, archaea.

Scientists representing the University of California at San Diego, as well as their colleagues from the German Max Planck Institute, concluded that Humans are made up of about 43% cellsThe rest of the space is occupied by various microorganisms (human microbiome).

Professor Rob Knight of the University of California is convinced that microbiome It takes up more space than the person.

“Each of us is more a collection of microbes than a human being.”





His colleague, microbiologist Sarkis Mazmanyan, is quite sure that a person is a combination of human DNA and the DNA of his intestinal microbes.

It is naive to believe that a large number of microbes do not affect our daily lives. It is their interaction that allows you to provide the body with vital vitamins.

Thanks to the improvement of antibiotics and vaccines, humanity defeated smallpox and stopped tuberculosis. But in the fight against “bad” bacteria, scientists have harmed and beneficial microorganisms, which increased the number of problems with immunity, there were new diseases.

Facts about bacteria in the human body:

1. The number of bacteria in our body exceeds the number of cells by about 10 times.
2. The baby is born without bacteria, but over the next three years its microbiome is formed almost completely.
3. Some bacteria can be harmful, others good. But there are bacteria that can be both harmful and beneficial, depending on the state of health of the person.

4. Bacteria can adapt to the effects of antibiotics and mutate, becoming dangerous to health.
5. Probiotics are not as good as they say. The fact that taking probiotics, which contain several types of microorganisms, we can not completely restore the microflora, consisting of thousands of their varieties.
6. Harmful food affects not only a person’s physique and weight, but also the type of microbes that live in the digestive tract.

So far, medicine aimed at restoring the microbiome is developing at an early stage. But researchers hope that over time monitoring of the bacteriological environment It will become commonplace, and it will allow more people to stay healthy.

Microbes in humans They live in huge numbers, which is worth looking under a microscope at the handprint of an 8-year-old boy. The picture scared many Internet users, and now they are much more likely to wash their hands.

And how much dirt remains on poorly washed hands, we have already told. Washing your hands is worth taking seriously.

In your opinion, microbiology Can we save humanity from incurable diseases? Or will it just add more problems?
