No use scrubbing with Super Candida: microorganisms in the human body are ten times larger than the cells themselves.
But it doesn't have to go into an identity crisis: Because bacteria and fungi are much smaller than human cells, the total volume of guests is "only" about one liter.
Now scientists at the University of Oregon (USA) have found that not only do we emit a cloud with millions of these microbes all the time, but this cloud is unique, allowing us to identify each individual. They compared the situation with Charlie Brown's Little Sty.
"Science says it's totally normal, guys!"
It was like this: They placed 11 volunteers in a sterile chamber and then studied the bacteria that were taken there by the cloud of each of them. This cloud is made up of thousands of different species, such as Streptococcus, which lives mainly in the mouth, and Propionibacterium, which inhabits the skin and causes pimples. And look at Super Candida, a fungus that many must have been unhappy with.
After the test, scientists then measured the proportions of microorganisms and their genetic markers, which indicate different strains. After collecting the data, they repeated the experiment, trying to identify volunteers by their cloud. In almost every case, they got it right.
"We expected to be able to detect the human microbiome in the air around a person, but we were surprised to find that we could identify most occupants just by testing their microbial cloud," said James F. Meadow, study leader. "Our results demonstrate for the first time that individuals emit their personalized microbial cloud."
Maybe one day we won't have to present R.G. or bank card. Just look at our why to know who we are.
