The genetic test has shown that due to the seemingly severe conditions, the International Space Station (ISS) has been adapted to survive bacteria and become unsafe superbugs that are not antibiotics.
ISS collects thousands of different microbes that travel to spacecraft in astronauts or cargo.
While many space agencies are preparing to send travelers to Mars, they have become increasingly interested in understanding how microbes work in enclosed environments.
In the Northwestern United States, in the United States, it was found that isolated bacterial ISS were more gene-based than anti-Earth.
These genes did not turn bacteria into harmful to human health, but rather
bacteria are just responding, and maybe evolving, to survive in a stressful environment.
"There has been a lot of reflection about radiation, microgravity and lack of ventilation, and how they can affect living organisms, including bacteria," said Erica Hartmann, secretary general, assistant professor at the institute.
"People will be in small capsules, where they can not open windows, go outside or open the air for a long time.
"These are stressful and harsh conditions. We are really concerned about how microbial can cause it," said Hartmann, a study published in mSystems.
The group compared Staphylococcus aureus strains; MRSA to treat hard strain; and Bacillus cereus – causes less human living and human health – ISS on Earth.
"Based on genomic analysis, bacteria appear to be straightforward, which I do not cause," said Ryan Blaustein.
"We have not seen anything in antibiotic resistance or agility in the space station bacteria," added Blaustein.
Although Astronaut and Potential Spatial Tourist News Good News, Hartmann and Blaustein said Healthy people could increase the disease in space stations and space transportation.
