[Characterization of the microflora of the small intestine (author's transl)].
Normal and abnormal microflora of the upper small intestine was studied in 356 patients. Low counts are characteristic of normal microbial colonization (eubiosis), changes in quality and/or quantity are pathological (dysbiosis). The latter status is described as overgrowth syndrome. We found some types of dysbiosis. Prevalent was type Dys1 with the highest counts and the greatest variety of bacteria and yeasts. In contrast to this, type Dys2 showed higher germ counts of only one genus like coliforms (Dys2 Coli), streptococci (Dys2 Str.), lactobacilli (Dys2 L.) or yeasts (Dys2 Y.). In dysbiosis, we frequently saw bifidobacterium and bacteroides. Simultaneous sampling from stomach, duodenum, and jejunum indicated different modes of colonization of these parts (oral or fecal type).
