Pseudomonas aeruginosa introduced directly into the stomach established itself more regularly in the intestinal tract of irradiated mice than of unirradiated mice. The irradiated mice had been exposed to 550 r total body x-irradiation 5 days before inoculation. This difference between irradiated and unirradiated mice could not be explained by differences in pH of gastric or duodenal contents, propulsive motility of the intestinal tract, or the ability of the intestinal contents to support growth of Pseudomonas in vitro.
直接引入胃内的铜绿假单胞菌在受辐照小鼠肠道内比在未受辐照小鼠肠道内更易定植。受辐照小鼠在接种前5天接受了550伦琴的全身X射线照射。受辐照小鼠与未受辐照小鼠之间的这种差异无法用胃或十二指肠内容物的pH值、肠道推进运动或肠道内容物在体外支持铜绿假单胞菌生长的能力差异来解释。
