When all goes to humans, our bacterial friends will continue. This space is sunny on the Earth, and while being aware of the microbial astronauts in international space stations, a team of researchers has found a new cause for concern.
A genome study with extracted samples from the common room on the station has, in other places, some of the ISS's bacteria that provide antibiotic resistance. Astronauts do not risk at this time, researchers said, from NASA's Jet Propulsion Laboratory, but they recall that the bacteria could be a threat in a limited space in the space station.
In this new study, the researchers described in detail the genome of these species and compared genomes of 1,201 genomes Enterobacter Earth tensions. And, by analyzing the bacterial genetic machinery, bacteria found that antibacterial drugs were resistant.
Nitin Singh, the first author of the research, stressed that these voltages are not virulent and do not have an active or special threat against astronauts. But Singh added, one of the tension found, Enterobacter bugandensis It is an opportunistic bacteria that can cause the disease. A computer analysis of species led to a significant risk to human beings in the future.
Future future of future astronauts work was part of the effort to understand how human life will be affected in space.
"An understanding of how living microbial lives in a closed environment helps us prepare for better health concerns," Singhe said in e-mail. "ISS offers us the opportunity to analyze the excluded options on many aspects of the space travel: how to interact with space microbiomes and life support systems," said Singhe
The enclosed closed system on a spatial system is a unique environment for microorganisms and bacteria in microorganisms. As the microbial species grow, adapt and multiply on the ground, they will do it in the same space. Local storage and storage facilities in the space station are kept clean, but microscopic organisms will now find a shelf and adapt to survival. Like researchers, some of these adaptations may have mutations that give resistance to antibiotics and bacteria can be very hard.
By better understanding the specific spaces in the space station, researchers want to figure out how to best protect astronauts. For example, when and how often it washed certain equipment on the board, Singh said.
The bacterial species in the space station do not create any danger, it exposes the immune human system in space, as explained by Singh. Therefore, in future deep-sea missions, astronauts can spend more time in space and bacteria can adapt more and multiply it, and may pose a higher risk of infection.
"At the start of the weakening of the immune system, the previously harmful microorganisms could be ill," Singhe said.
This study was published in the journal BMC Microbiology.
