[Peculiarities of microbial colonization of the intestinal tract in newborns and pre-term infants in intensive care units].
The aim of the study was to compare the development of intestinal microflora in clinically healthy newborns, born by mothers with physiological pregnancy, and in small premature infants, who were treated in intensive care units (ICU) using various regimens of antibacterial therapy. The study revealed that the most frequent bacteria found in the intestinal tract of healthy infants at the and of neonatal period were bifidobacteria, enterobacteria, and coagulase-negative staphylococci and enterococci. Together with large quantity of autochtonous bacteria, the study revealed conditionally pathogenic microorganisms, such as klebsiella and coagulase-positive staphylococci at the end of neonatal period. The intestinal microflora of premature infants in ICU, treated with a combination of third generation cephalosporins and aminoglycosides from the first hours of life, was characterized by total absence of indigenous microflora, and prevalence of enterococci and staphylococci. The results show that the first stage of antibacterial therapy of preterm infants in ICU should be based upon the principles of selective decontamination.
