Mountaineers contaminate Everest with resistant microbes

Researchers were surprised to find that microbes living in the human body can survive in harsh environments.

American scientists discovered Staphylococcus and Streptococcus bacteria, which come from the human body, on the top of Everest. This was reported by ScienceAlert.

The researchers noted that extreme weather almost always reigns at the summit and should kill any life, but it turns out that some microbes can thrive in such a harsh climate.

According to experts, the found samples were taken about 170 meters from the place where hundreds of tourists set up their camps every year before climbing to the top of Everest. They are carried by climbers through saliva, sweat and cough.

“We predict that if we take samples from the mountain areas most used by humans, we may find more microbial evidence of human impact on the environment,” the scientists said.

Experts also emphasize that this work has implications for the search for extraterrestrial life, for example, if humans ever reach Mars.

It was previously reported that scientists discovered that one of the microbes common in the ocean, as well as the species closest to it, produces oxygen without sunlight.
