Researchers have found five stretch marks of a bacterium, which is capable of resisting multiple drugs. They are quite similar to the infections, one tend to acquire from a hospital. Now one can find them on the International Space Station. This has now, raised concerns related to the health of the organisms for carrying out missions in the future. It resembles a bacterium that has been recently discovered to infect newborns. There are certain elderly patients all across three hospitals, which have also got infected with the same. The bacterium is named Enterobacter bugadensis. The strains that are found on the International Space Station, in their current state do not cause any infection to human beings. Still, their genes act as if they are three pathogenic Earth strains. Hence, there is enough justification for carrying out further research.
The five bacterial strains were resistant towards five most commonly-used antibiotics like penicillin, resistant etc. Enterobacter species usually remain located in the human digestive tract as well as in soil and sewage. Still, one can notice its implications in different infections as well, like bacteraemia and endocarditis which are acquired from hospitals. The bugs present in the International Space Station possess a 79 percent possibility of causing infection to human beings. One good thing is, Dr. Kasthuri Venkateswaran, the senior research scientist said that there is no cause for alarm as of now. The doctor then emphasized the need to conduct further research in living creatures. There is a feeling that additional research will help to find out exactly how the factors in the environment are linked towards space travel, which impacted the bacteria.
Experiment by a Russian came to an end in the month of July. In a similar manner, it went on to discover that terrestrial bacterial that got delivered to space, helped in showing a marked increase in aggression while they had gone back to earth. There was also a significant amount of resistance noticed from the antibiotics. Four samples of E. Bugadensis were collected from station toilet of the area. In March 2015, one was on the Advanced Resistive Exercise Device foot platform, which was part of a greater effort to conduct a microbial census of the station.
