Microecological problems have escalated recently in clinical medicine. We studied the microecology of the upper small bowel. Duodenal flora was examined, displaying microbial growth in 90.8% of the 400 patients examined. The microflora was classified according to germ quality into definite types of colonization. Frequency of microbial colonization is normally 36.7% and 63.3% by overgrowth, indicating differing dysbioses. Simulation of microbial overgrowth in the duodenum is possible with a continuous-flow culture, demonstrating a biocenosis of several groups of micro-organisms with great metabolic activity. Continuous culture technique suggests possibilities for future studies of human gastrointestinal microecology. © 1989 MMV Medizin Verlag GmbH München.
