The effects of space flight on the growth and pathogenicity of microorganisms and on the human immune response are reviewed giving attention to the implications for spacecraft design. The major sources of microbes within space habitats on long-duration missions are listed including food, crewmembers, and payloads. Many of the microorganisms are shown to be airborne suggesting that effective air-filtration techniques are required for the designs of the Space Station and other vehicles. It is shown that microbial growth rates generally increase during space flight, and space flight is thought to attenuate the human immune response. Some beneficial roles for microbes are identified demonstrating the need for careful control, application, and monitoring of microorganisms in the long-duration spaceflight environment.
