[Intestinal flora under conditions of stress]

In healthy probands influenced by endocrinic stress (application of ACTH, growth hormone, and triiodothyronine) the microflora of the content of the duodenum and of the feces is examined. After three weeks, only, rising numbers of bacteria could be detected in the duodenal content. The number of the aerobic bacteria, mainly of the coliforms in the feces, decreased whereas the number of the anaerobic germs increased. This stress model seems to be suitable for such researches.
