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.
对来自8天、30天和63天飞行任务的机组人员唾液和粪便中的乳杆菌菌群的物种组成及生物学特性进行了研究。共检测了593株乳杆菌。太空飞行并未导致乳杆菌在生理、生化、拮抗特性或溶菌酶活性方面发生显著变化。它们并未使消化乳杆菌菌群的物种组成发生剧烈改变或趋于统一。然而，不能排除乳杆菌在机组人员之间传播的可能性，其概率会随着飞行时间增加。
