The paper describes sanitary-hygienic and technological investigations aimed at development of the sorption method of water reclamation for personal hygiene needs of cosmonauts from wash water. Catamine-AB was used as a detergent with bactericidal properties. Manned experiments helped to identify the conditions that provided an adequate cleaning of skin and simultaneous sterilization of wash water. The technology of wash water purification was developed, proper sorbents were selected and recommended values of their use were established.
The antibacterial activity of surface-active substances -- catamine-AB, catapine B-300, GIPH-200 and Tego-51 was measured on the E. coli and Staphylococcus aureus cultures and anthracoid spores. The purpose of the measurements was to explore the use of the substances as urine conserving agents. Catamine-AB showed the highest antibacterial activity. Anthracoid spores exhibited the highest resistance to the substances; staphylococci were less resistant than E. coli. Investigations of the effectiveness of urine conservation demonstrated that catamine-AB at a concentration of 0.1% killed all Staph. aureus and E. coli. Therefore, it can be recommended as a urine conserving agent.
This paper presents the results of microbiological examinations of the Salyut-6 crewmembers and environment. There were few cases of adverse changes in the automicroflora composition, i. e., propagation of staphylococci of a certain biotype among crewmembers. However, no over manifestations of infectious pathology were seen. This allows the conclusion that personal hygiene measures and general hygiene and antiepidemic measures taken before and during Salyut-6 missions were adequate and efficient.
