Researchers have found that you can live in the International Space Station (ISS) "super bugs".
Researchers and microbiologists at NASA Jet Propulsion Laboratory found that there are five types of enterobacter types in the ISOBs for invasive and exercise areas.
Previous studies showed that they were changing the space in the wrong way and adapting them to the new environment as "supercharged" in space. This led to microbial mutations and changed them. In fact, a particular bacterium suffered more than a dozen mutations in space, which improved its ability to multiply.

These bacteria formed biofilm in equipment and biofilm increased the growth on the ground with faster growth than similar biofilms. This means the rapid multiplication of these bacteria.
Dr Nitin Singh, the author of the first research, says "Given the high resistance to the ISS genomes and the increased possibilities of identifying identity, these species can create health considerations for future missions … However, it is important that the tensions found in the ISS were not to understand giblets, This means that they are not active threats to human health, but something to be controlled. "
However, computer modeling and simulations have shown that bacterial changes make 79% virulent beings and cause human illness. These bacteria on the ground develop anti-antibiotic resistance and can only infect those who endanger immunity. It may not be in space because the group will explain why 112 genes have bacterial pathogens on the ground.
Enterobacter strains were resistant to antivirals such as cefazolin, cefoxitin, oxacillin, penicillin, rifampin, and others.
JPL analyzes the microbes from space stations in a normal way so that astronauts do not harm or cause sensitive equipment. Microbiology Kasthuri Venkateswaran said: "To find out about the bacterial species in the ISS, we have used different methods to determine the genome in detail. Five ISS Enterobacter tension genomes have been found to be three genetically similar strains found in the Earth." These three strains are found in a single species of a bacterium they were there Enterobacter bugandensisPatients were diagnosed with illness and a risky patient in three hospitals (East Africa, Washington State and Colorado).
These samples came from 2015. Venkateswaran said: "Whether or not it is an opportunistic pathogen E. bugandensis It causes the disease and the amount of the threat depends on many factors, including the environmental ones … More living studies need to know the effect of ISS conditions, such as factors of microgravity, other spaces and space factors, can be pathogenesis and virulence.
