It's a great spot for superbugs, a new study suggests, or even space. According to the research, the International Space Station (ISS) found resistant antibiotics to bacteria. And while bacterial astronauts do not get sick, the authors say it is quite likely.
The authors behind the research, last week published in BMC Microbiology, are part of the NASA Jet Propulsion Laboratory, mainly managed by the California Institute of Technology. NASA's most robotic space and space mission in Earth Sciences is Mars Curiosity Rover, as well as NASA Deep Space Network satellites.
The new study is an update on the continuous work of researchers. In January, the research group began to investigate the bacterial genetics of the 2015 ISS surface samples. Within these samples, anti-bacterial bacteria have been found to be more than 100 genetic bacteria that are used to make antibiotics. And the strains of a specific bacterial species, Enterobacter bugandensisThey were resistant to the nine anti-antibiotics that were opposed.
In the latest study, they expected the risk of human health being compromised. So the ISS tension genetics have been against three temperatures E. bugandensis He gathered people on the ground. ISS voltages were very common with terrestrial voltages, including antimicrobial resistance and end-to-end genes (a person's microbiological potential to infect). Based on similar genetic similarities, the team calculated the voltages of ISS 79 percent likely to be a disease or pathogen.
According to the results, the authors have "written these species to make important reflections on the future missions health".
Enterobacter Most bacteria live, including our branches. Usually they do not cause illness. But in people with poor immune systems, such as hospital patients, they can cause serious and dangerous infections. And I found it recently E. bugandensis In sepsis, immune infection is too great for infections that can infect the organs in newborns and elderly people.
Opportunistic infections are bad enough, but antibiotic resistance is increasingly difficult to treat. In space, when medical resources are limited and astronauts have the weakest immune systems, the potential infections could be disastrous.
Fortunately, the authors say, there is no evidence that these evidence affects ISS disease. And there is still a lot of work to be done to find out about these problems in order to solve these errors, as well as the conditions of space travel that promote growth or are more dangerous. A scientist, for example, has specified that microgravities can evolve faster than bacteria in the Earth or slow down the germ mortality from antibiotics. Future research must include live experiments in space.
"Whether it's an opportunistic pathogen E. bugandensis It causes the disease and is a threat, it depends on many factors, including the environment, "said Kasthuri Venkateswaran, the leading author of the Jet Propulsion Laboratory, a scientific researcher in the Biotechnology and Planetary Protection Group, in a statement." Other in vivo studies need These are the ISS conditions, such as microgravity, the impact of other spaces and space-based nuclear factors, may be pathogenic and virulent. "[BMC Microbiology]
