An article written by Richard Mains, Mains Associates, titled “Microgravity Boosts Microbe’s Virulence” covering Dr. Cheryl Nickerson’s NASA-sponsored research with Salmonella. She has demonstrated that the microgravity of spaceflight enhances the disease-causing potential of this common bacteria that causes millions of cases of gastrointestinal disease per year and the gene activity underlying this change may be the key to developing new ways to treat and prevent such costly infections.
