As inevitable fellow travellers on the bodies of astronauts, spaceships, or equipment, terrestrial microorganisms will undoubtedly come into contact with extraterrestrial environments. Researchers from the Radboudumc describe in an article in Astrobiology that bacteria can survive on an ‘extraterrestrial diet’, which affected their pathogenic potential.
No matter how well astronauts and material are decontaminated, co-travelling microorganisms into space cannot be prevented. Given the enormous adaptability potential of bacteria, it is conceivable that they will sometimes survive space travel and be able to settle in an extraterrestrial environment.
For this study, four non-fastidious environment-derived bacterial species with pathogenic features were selected, including Klebsiel...
