Microbes and Microgravity in Space
There are over one hundred strains of bacteria and fungi that have been identified from manned space missions. These microorganisms survive and propagate in space. Much effort is being made to ensure that the risks from exposure to the microbes are significantly reduced. Spacecraft are sterilized as good control practice by flushing with antimicrobial agents such as ethylene oxide and methyl chloride; and astronauts are quarantined for several days prior to a mission. However, these measures only reduce the microbe populations rather than eliminate them. Microgravity may increase the virulence of specific microbes. It is therefore important that the mechanisms responsible for this problem are studied and the appropriate controls are implemented to ensure that astronauts, in particular those that are immunocompromised, are not affected.
