[Dynamics of the establishment of intestinal microflora in healthy full-term newborns].
A study was made of the dynamics of establishment of the intestinal microflora in 79 healthy mature neonates born of healthy mothers. A total of 223 bacteriological examinations were conducted. A stable prevalence of bifidobacteria over the aerobic portion of the intestinal biocenosis occurred in all the children from the 8th day after birth. Along with this the following bacteria were continuously present in the intestine: lactic bacilli and streptococci E. coli, enterococci and staphylococci; however, their portion in the biocenosis was not great. Bacteroids, microbes of the Proteus genus, and yeast-like fungi were found in the cultures only before the establishment of a high bifidobacteria level. Conditionally pathogenic microorganisms and their associations were continuously revealed in 19.8% of healthy mature neonates. Apparently the qualitative prevalence of bifidobacteria prevented the clinical expression of dysbacteriosis in these children.
