Identification of fungi isolated from astronaut nasal and pharyngeal smears and saliva

As part of a series studies regarding the microbiota in manned space environments, we isolated fungal strains from nasal and pharyngeal smears saliva 21 astronauts preflight, in-flight, postflight. On ground, 120 43 genera environmental fungi were astronauts. The dominant Cladosporium, Penicillium, Aspergillus. Only 18 four inside International Space Station. These are currently thought to be harmless, but regular screening cleaning necessary prevent fungus-related health disorders.
