Interplanetary threat: aggressive bacteria mutants returned from space


Scientists from Russia notice of microorganisms, which returned to Earth after a long stay in space, the increased aggressiveness and resistance to antibiotics. The researchers concluded that in the future, individual mutated individual can even be dangerous for life on our planet, and beyond.

Relevant findings included in the national report on the results of fundamental space research. To provide it professionals plan in July at a meeting of the international Committee on space research in the United States.

In particular, the researchers noticed that the strains of bacteria Bacillus subtilis, which are held in space for 31 months, an increase of the resistance to applied 6 of the 8 antimicrobial drugs. Consequently, when exposed to this kind of microorganisms range inherent in the open space factors, survive the most aggressive and drug-resistant strains.


Terrestrial microorganisms subjected to mutation in the course of space research, can, according to experts, a danger to life on Earth, therefore, it must be taken into account in the requirements of “planetary quarantine”.
“Since it was shown that organisms are able to survive in space, hypothetically, in the distant future possible entry of alien substances from other planets to Earth and to other planets from Earth” – leads the RIA Novosti words of the report of the Russian researchers – “in addition, the danger may be returned and terrestrial bugs that flew into space, visited another planet and an unknown image is transformed in the atmosphere”.
The knowledge obtained by Russian experts plan to use to develop effective measures to protect our planet from such threats.
