[Lactobacillus flora of the digestive tract of the crews of Soiuz-13 and Saliut-4].
The species composition and biology of lactoflora of the saliva and feces of crewmembers from 8-, 30- and 63-day flights was investigated. Altogether 593 strains of lactobacilli were examined. The space flights did not cause significant changes in physiology, biochemistry, antagonistic properties or lysozyme activity of lactobacilli. They did not change drastically or unify the species composition of the digestive lactoflora. However, transfer of lactobacilli from one crewmember to another cannot be excluded, its probability increasing with flight time.
