[Qualitative and quantitative composition of intestinal microflora in healthy young children].
The results of the qualitative and quantitative analysis of the microflora of the large intestine in 45 healthy children aged 6, 8, 10 months and 1 year, living in Moscow, are presented. During the first year of life high concentrations and detection rate of not only bifidobacteria, enterococci, nonpathogenic Escherichia, but also bacteria, commonly regarded as opportunistic were typical. The latter include lecithinase positive Clostridium, citrate assimilating enterobacteria, as well as Escherichia with low biochemical activity and capacity for hemolysin production. In addition, this group also includes coagulase-positive staphylococci. Later on, as these children become older, opportunistic bacteria are partially or completely eliminated under normal conditions. Suggestion is made that the composition of intestinal microflora depends on protective and other systems of the host at different periods of life, as well as on the character of nutrition and the microbial contamination of the environment.
