how many kinds of bacteria and microbes will the children carry in the outdoor play? A mother with a scientific spirit tries to find the answer herself. Mother Tasha Sturm owns a 8 year old son. When he returned from outdoor play, he printed his palm in a TSA culture dish, covered the lid for 24 to 48 hours in a temperature environment of 37 degrees, and then put it at room temperature for several days. Very beautiful hand like colored flora, yeast and fungal colonies.
Sturm firmly believes that the circular area of the lower right corner of the photo is bacteria, usually in the dust. Other white stains may be Staphylococcus, and orange and yellow may be yeast. Maybe some people will feel numb when they see these bacteria, but Sturm thinks that the results are expected, which are often touched in our daily life. Some bacteria are good for our immune system, and our body can resist most other bacteria. She said: "to provide some family recommendations, if you want to have a healthy immune system, you need to expose children to these things." But it doesn't mean you don't need to wash your hands.
