Found bacteria that the human immune system has never encountered before

A joint study of scientists has shown that there are some bacteria that are so foreign to

person that immune cells cannotregister. At the very least, the new discovery casts doubt on the long-held theory of universal immunity. According to it, human cells can recognize, if necessary, any bacteria with which they interact. However, the study found that some bacteria are determined solely by their surrounding or local habitat. The results of a new study have been published  In the magazineScience Immunology.

A group of scientists had to look deeper than3,000 m below the surface of the Earth to find such alien bacteria for humans. They will help scientists better understand how the human immune system reacts to completely foreign organisms.

“Our team has discovered and cultivated newbacteria that are completely impervious to the human immune system,” said Randy Rotian, assistant professor of biology at the New York State College of Arts and Sciences and co-author of the paper. He emphasizes that the bacteria did not cause any response from the human innate immune system. According to Rotyan, this discovery was unexpected for scientists.

This study is the culmination of a five-yearresearch carried out over 3,704 km (2,000 nautical miles) in the central Pacific Ocean. Scientists have sequenced thousands of genes, doing most of the work in the floating laboratory.
