Skylab environmental and crew microbiology studies

The objectives of the Skylab microbiology studies were to detect the presence of potentially pathogenic micro-organisms on the crewmembers and their spacecraft and to obtain data which would contribute to an understanding of the response of the crew's microbial flora to the space flight environment. These data were interpreted in light of the theories of microbial simplification, intercrew transfer of medically important microorganisms, in-flight auto infections, and postflight microbial shock, which have been proposed by various authors.
