An ecological investigation of alimentary flora of man was made by eight selective media and six specimens recovered from stomack, duodenum, gall bladder, gall ducts, jejumun, transverse colon of 112 patients who were undergoing laparotomy for either stomack cancer, duodenal and stomack ulcer, or gall ducts disease of them. Similarities and dissimilarities of obtained results proposed existence of four different ecological sites, stomack, upper intestine, transverse colon and gall ducts in the alimentary track. Such flora speciality of a different site, however, was much influenced by pathological changes thereon. Influences from another pathological site upon flora of a healthy site were variable. Existence of the glycolytic layer, which was found by Onisi et al in the human mounth was also proved among alimentary flora with some exceptions; Enterobacteria associated with this layer, population of Candidae did not run parallel with Lactobacilli, and fusobacterium count slightly related to that of Staphylococci, a member of the layer.
