MICROBIOLOGIC STUDIES OF THE TWO-MAN SPACE CABIN SIMULATOR Interchange of Oral and Intestinal Bacteria

摘要

Studio were initiated to gain an understanding of the degree of meiotic interchange to be expected between individuals under conditions of dose occupancy, as would occur during space travel. Experiments were performed on subjects confined within the two-man space cabin simulator at the USAF School of Aerospace Medicine, Brooks Air Force Base, Tex. Results from eleven experiments, lasting from 14 to 80 days, are presented. Oral and intestinal surveys were conducted on each individual prior to, during, and following confinement. "Marker" organisms, initially harbored by only one of the individuals, were used to establish evidence of meiotic interchange. Implications of these findings, as related to future space flights, are discussed.
