Does the human body can live without the bacteria?

There are facts that say that there are trillions of bacteria that live in groups and the skin on our bodies. And until now this man would not be possible to live without food, nutrition and also included with the bacteria.

In the human digestive system, there are bacteria that help to digest foods such as vegetable fibers derived from, which can not be digested by our own bodies. Nutrients from the foods we absorb each day are a blessing service from bacteria. Bacteria also can supply the needs of the human body vitamins like biotin and Vitamin K. A research ever conducted on guinea pigs developed in a sterile environment without bacteria has been shown that these poor animals are malnourished and die more quickly when compared with animals that have the bacteria in the body.

On the outside of the human body there are millions of bacteria which consist of 200 species that dominate the skin environment. On the inside of the human body are bacteria that have proven to be very important to improve the human immune system. Understanding of bacteria, especially in good times and the dangerous bacteria will be able to provoke the human immune system response against a pathogen in the future.

In humans the amount of good bacteria and bad bacteria should be balanced. But if the number of pathogens is too much interference will usually cause disease or infection.
