Can Man Live Without Bacteria?

6 Sep 2010

cleanupThe fact that there are trillions of bacteria that live in the skin and in our bodies naturally make us shudder. However, as far as humans could not possibly live without food and nutrition, we can not live without bacteria.

In the digestive tract, the bacteria help digest food, such as fibers derived from vegetables, which we can not digest itself. “We get nutrients from food bacteria diasup blessing services,” said Anne Maczulak, a microbiologist and author of Allies and Enemies: How the World Depends on Bacteria.

Step that the bacteria that supply the needs of our vitamins, such as biotin and vitamin K. Research carried out on guinea pigs that were bred in a sterile environment without bacteria showed that poor animals are malnourished and dying faster than animals that have the bacteria in their bodies.

Outside the body, millions of bacteria which consists of 200 species that dominate the skin environment. Both within and outside the body, exposure to the bacteria proved to be very important to enhance the immune system.

According to Gerald Clalahan, microbiologists, exposure to the bacteria, whether benign or malicious, will provoke the immune system response against invasive pathogens in the future. In research published in the New England Journal of Medicine, he also shows that babies and children who live in the environment is too clean it more susceptible to suffer asthma and allergies.

In our bodies, the number of good bacteria and bad bacteria are usually balanced. However, if the number of pathogens is too much, it usually arise disorders or infectious diseases.
