Abstract

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).

因此我们才能看到
对356例上小肠正常与异常菌群进行了研究。低计数是正常微生物定植(良性)的特征,质量和/或数量的变化是病理性的(生态失调)。后一种状态被描述为过度生长综合征。我们发现了一些类型的生态失调。以Dys1型为主,细菌和酵母菌数量最多,种类最多。与此相反,Dys2型只有大肠菌群(Dys2 Coli)、链球菌(Dys2 Str.)、乳酸杆菌(Dys2 L.)或酵母(Dys2 Y.)一个属的细菌计数较高。在生态失调中,我们经常看到双歧杆菌和拟杆菌。同时从胃、十二指肠和空肠取样表明这些部位的定植模式不同(口腔或粪便型)。
