[Intestinal microbiocenosis at the critical periods of child development].
The bacteriological study of fecal specimens obtained from 595 children at different critical periods of the development of their immune system was carried out. The comparison of intestinal microflora in children at the critical periods of the development of their immune system revealed that in children under 1 year considerable changes in the microflora composition were observed during the first 6 months of life. These changes, most pronounced in children aged 1 month and 3-6 months, were characterized by decreased level of indigenous microflora and an increase in the qualitative and quantitative content of aerobic microflora with the representatives of the family Enterobacteriaceae playing the dominating role. In boys such disturbances were manifested to a greater extent than in girls.
