Mutated Drug-Resistant Bacteria Proliferate on International Space Station

New research reveals that strains of Enterobacter bugandensis on the ISS have become genetically distinct from their Earth counterparts, raising concerns about astronaut health.

• Studies show Enterobacter bugandensis, a multi-drug resistant bacterium, has mutated under ISS conditions, becoming functionally distinct.
• The bacteria's adaptation includes increased antibiotic resistance and potential virulence, posing a risk to astronauts' immune systems.
• Genomic analysis of 13 ISS strains reveals significant differences from Earth strains, suggesting unique evolutionary paths.
• The unique ISS environment, including microgravity and elevated radiation, facilitates rapid microbial mutations.
• Researchers emphasize the need for robust preventive measures to protect astronaut health from these pathogens.
