[Creating the optimal microecology of the intestines in premature newborn infants with the sour-milk mixture "biphilin"].

The paper is concerned with formation of intestinal biocenosis in premature infants and with approaches to the correction of its disorders with the aid of biphilin, a special mixture prepared from sour milk. Ninety newborns showed the derangement of biocenosis of various intensity by the 6th to the 10th day of life. Application of biphilin for 2 to 6 weeks as part of the multimodality treatment of such children made the intestinal microflora return to normal.
