Microbes and Outer Space

Growth of microflora on the astronauts in space faster than on Earth. It is feared because it can disturb the metabolism if the astronauts linger in its mission in space.
A professor from the Center for Infectious Diseases and Vaksinologi at The Biodesign Institute, Arizona State University, USA, Cheryl Nickerson, on Tuesday (07/26/2011), said that, the U.S. space agency (Nasa) is to take the microbes become one of the considerations in decision-making mission astronauts into space.

And takes medication that can be used to prevent microbial resistance is. At least one type of microbes that are pathogenic, ie Salmonella sp, known to be more virulent in space.
Besides changes in gravity also alter the activity of several other microbial species, among them, the bacteria Pseudomonas aeruginosa that can disturb the respiratory astronauts, showing similarity of molecular genetic changes in Salmonella.
