A man is 90% of germs

The human body is almost entirely made up of micro-organisms. However, the first time is not afraid of standing, writes Daily Mail: these creatures - not alien life forms. For trillions of microscopic life forms of the human body is home."We are, in fact, only 10% of men, and all the rest - the microbes," - says Dr. Roy D. Slitor of the Irish Institute of Cork. For four years, a thorough study of the subject, he concluded that the proper role of bacterial populations living in the human body, unfairly diminished.Our relationship with single-celled creatures were so close that progressive scientists are now considering human and bacteria living in it as a single super-organism. "To date, the bacteria are considered as a virtual body, waste products which is much higher than that of the liver," - explains Dr. Slitor.According to him, in the human body contains about 500 different species of bacteria. Through their incessant reproduction in an adult population of about 100 trillion-celled creatures - almost ten times more than the trillions of cells that make up the human body itself. For example, only in the intestine contains almost 2 kg of bacteria.According to Dr. Slitora, bacteria not only our companions, but indispensable assistant. "This is a bacterial-human interaction for the most part is in the nature of symbiosis - says the scientist. - This means that in exchange for food bacteria involved in digestion, production of vitamins and strengthen our immune system." In addition, the friendly bacteria protect the host against infectious agents, fighting the "enemy" bacteria.For fans of yogurt and other "live" dairy products, this news is certainly good. But Dr. Slitor warns that strengthen the ability of "probiotic" products is very short-lived. "Most of these bacteria are not retained in the body. They pass through the body without being able to organize the colony" - sadly he says. On the other hand, the constant use of such products can enhance the beneficial bacteria colonies. This is especially true when the body is weakened antibiotic.However, the symbiosis of living organisms, we recall, is possible not only with beneficial bacteria and pathogenic microbes. Not long ago, a research team from Feinberg School of Medicine at Northwestern University found that in the genome of the pathogen of gonorrhea bacteria Neisseria gonorrhoeae was found a fragment of human DNA.And even earlier, scientists have found that bacteria can be an excellent source of hydrogen, which can be used to clean and with powerful engines. Discovered in 1993 on the Pacific coast in Texas microbe threatens to turn into a fuel of the future.Incidentally, some scientists believe that life itself, we have to microorganisms, which are listed from space. After all, even the most primitive bacteria is in their DNA about 6 million bits of information that can be copied into new organisms. It is possible that this argument into account, researchers NASA, a year ago decided to equip the space mission, the crew of which were not people, but, again, the bacteria.
