A new study by US researchers shows that the microbes on board the International Space Station (ISS) are changing to adapt to challenging space conditions. The research, led by Professor Erica Hartmann, has been used by scientists from Northwestern University in the United States to determine if bacteria on board the ISS are modified to fit extreme conditions of space and do not necessarily pose a threat to the station's team.
found that IAS bacteria contained genes different from their terrestrial counterparts, but this does not mean that they are more harmful to human health.
Although the results bring good news, this does not mean that diseases can not spread in stations or spaceships.
"Astronauts are extremely healthy people […] but we do not know what will happen," he said, adding that there was no way if a Infected person is placed in a bubble closed in space.
According to Hartmann, as speculation about sending people to Mars becomes more and more serious, there is a growing interest in understanding the behavior of microbes in the interior.
Concerns about microbe mutations in the ISS appeared in November of last year, when a group of scientists discovered that these microorganisms were resistant to several drugs.
