Salmonella in space

npj Microgravity - 09 March 2021 13 March, 2021

New study from space station looks at human cells infected with Salmonella typhimurium. The cells were compared with cells infected on the ground on Earth to see what changes may occur in space. Spaceflight uniquely alters the physiology of both human cells and microbial pathogens, stimulating cellular and molecular changes directly relevant to infectious disease. 
The scientists found evidence that changes in the cells brought on by a microgravity environment may lead to salmonella being more virulent in space.
There were limitations to the study; not all samples that came back from space were able to be analyzed as fully as the scientists were hoping to. There were also small differences in the amount of pathogen administered to cells on the ground compared to inflight.
