A finding has come to light about the survival of microbes on NASA’s International Space Station (ISS). Bacteria cells found changing their shapes even after getting treated with regular antibiotics.
The research has made at the University of Colorado by the team of researchers which led by Dr Luis Zea. The study discovered that the bacteria could cause the lethal problems to the astronauts which can be severe infections because of the near about weightlessness environment.
Researchers along-with CU Boulder’s BioServe Space Technologies exposed in an experiment which got done in zero gravity environment and conducted aboard the ISS that E. coli bacteria can “shape-shift” smartly and survive even after in the various doses of antibiotic gentamicin sulphate. Usually, the antibiotic kills the bacteria in the environment of earth. Whereas, in space, the results were unusual because exposure to gentamicin sulphate followed to 13-fold increase in bacterial cell numbers and 73 percent reduction in cell volume size. According to the researchers, this kind of morphism is helping the bacteria to survive in the space.
Ironically, the odd fact is the drug gentamicin sulphate usually helps in killing micro organisms on Earth But in space, the same drug is helping the ...
