Spaceflight Makes Bacteria More Infectious

This article reminded me of the Andromeda Strain:

Spaceflight Can Change Bacteria Into More Infectious Pathogens

“Bacteria that became more dangerous in space may help scientists design better antibiotics on Earth, U.S. researchers said on Monday. They found that a type of Salmonella that causes food poisoning became more virulent after spending 12 days at near-zero gravity in the space shuttle, killing more mice than Earthbound bacteria and killing them more quickly.

Their findings, published in the Proceedings of the National Academy of Sciences, might help protect both astronauts and people infected on the ground, said Cheryl Nickerson of the Center for Infectious Diseases and Vaccinology at Arizona State University.”
