This handprint blew the Internet. Now I'm going to wash their hands as often as possible ...

Our body is home to a huge number of germs and bacteria without a microscope to see them impossible. Although it's probably just as well that we can not see all this horror.

Recently, the Internet has flown silhouette picture hands in a Petri dish. This print belongs to 8-year-old son, Tashi Starman. So she decided to check how many germs on the hands of her child, and she works as a laboratory assistant at Cabrillo College, California, it has not made it difficult. She filled petri dish nutritious tryptic soy agar and asked her son to leave the imprint of his hands in the tank after he played in the street. The result of this little experience only once again proves to us that you need as often as possible to wash your hands.

In a petri dish of bacteria develop only 2 days.





bacteria that has grown up Tasha, should not be taken as a biological hazard, because the presence of bacteria on the skin - this is normal.





After the bacteria are both outside and inside the body, providing a good immune system and gastrointestinal tract.





However, not all these bacteria are useful. Since the woman has not yet analyzed the grown microbes can not say that at the hands of her son were both dangerous and helpful bacteria only. But do not forget that the hands should be washed after each exit to the street!
