Multi-drug resistant bacteria found on International Space Station mutate to become functionally distinct

Principal Investigator Dr. Kasthuri Venkateswaran of NASA’s Jet Propulsion Laboratory led a team that studied 13 strains of the bacterial species Enterobacter bugandensis that were isolated from the International Space Station (ISS). E. bugandensis is a bacterium notorious for being multi-drug resistant.

Study findings indicate that under stress, the ISS isolated strains were mutated and became genetically and functionally distinct compared to their Earth counterparts. The strains were able to viably persist in the ISS over time in significant abundances….
