This is how our bacterial partner will go wherever people go. In space, spacecraft has the same reality on the planet, and cosmonauts know microbial cosmonauts at the International Space Station, and a group of researchers find a new cause for concern.
The genome analysis of the samples collected from the station's space toilet showed elsewhere that some bacteria in the DNA have genes that provide antibiotics resistance. At present, there is no danger for cosmonauts, says NASA's Jet Propulsion Laboratory, but it may be bacteria in a limited space environment.
In this new study, researchers fully described the genome of these species and compared their genes with the gene of 1.291 Enterobacter Strain from the ground. By studying the genetic makeup of bacteria, bacteria have also been able to see that they can be resistant to antibacterial drugs.
The first author of the study, Nitin Singh, stated that these strains were not harmful, which would not be an active or direct threat to cosmonauts. But, Singh says, one of the strains found, Enterobacter bugandensis this is opportunistic pathogen, which can cause illness. Computer expertise has shown that there is a risk of harm to people in the future.
This work has been a part of the effort to better understand how future cosmonauts will affect human life in space.
"Understanding how massage life will grow in a closed environment, like the ISS, will help improve health issues that arise during a space trip," Singh said. "The ISS will enable us to explore the most common aspect of space travel: the interaction of microbios and space systems of spacecrafts," Singh said.
On board the space station, the closed system is the unique environment for bacteria and other microbial organisms. Although microbic species grow, adapt and grow on Earth, they are the same in space. The equipment and storage facilities and cranes of the space station are kept clean, but the microscopic organisms find shelter and survival. Researchers have found that some adaptations can be extremely difficult for mutations and bacteria to be counteracted against antibiotics.
With a good understanding of the type of space station, scientists know how to protect the cosmonauts better. For example, he could know when and how often he was cleaning any equipment on board, said Singh.
At the space station, bacterial species does not cause current danger, but human immune system is spoiled in space, Singh said. Cosmonauts may be exposed to extreme cosmic exposure, and future deep space missions that may take longer to adapt and reproduce bacteria.
"Once the immune system begins to weaken, harmless microbes can cause you to get sick," Singh said.
