[The microbial colonization of the skin of newborn infants rooming in with the mother in maternity homes]. / Mikrobnaia kolonizatsiia kozhi novorozhdennykh detei pri sovmestnom prebyvanii s mater'iu v rodil'nykh domakh.

The formation of skin biocenosis in children under the conditions of a maternity hospital with the joint care of mother and child was studied with the use of commercial bacteriological imprints manufactured in the USSR. The colonization of newborn infants in maternity hospitals with opportunistic, saprophytic and normal microflora was established. In newborn infants aged up to 5 years low skin resistance to colonization and, as a consequence, frequent colonization of the skin with opportunistic and saprophytic microflora was observed.

[The comparative characteristics of the vaginal microflora in parturient women who are carriers of Streptococcus serogroup B and in those who are free of carriage]. / Sravnitel'naia kharakteristika mikroflory vagalishcha rozhenits--nositelei streptokokkov serogruppy B i svobodnykh ot nositel'stva.

In the study of vaginal microflora in parturient women, carriers of group B streptococci (GBS), and those free of carriership a wide range of microorganisms, represented by aerobic and anaerobic species with the prevalence of lactobacteria in both groups of women, was isolated. The composition of vaginal microflora in parturient women did not depend on the presence of GBS in this biotope or on the level of colonization by lactobacteria. The colonization resistance (CR) of the vaginal mucosa had essential influence of the level of carriership with respect to GBS and a number of representatives of the symbiotic microflora of this locus. In the majority of cases GBS were isolated from parturient women with low CR.

[Microbial colonization and succession on the faucial mucosa in newborn infants rooming in with their mothers in a maternity hospital]. / Mikrobnaia kolonizatsiia i suktsessiia na slizistoi obolochke zeva u novorozhdennykh detei pri sovmestnom s mater'iu prebyvanii v akusherskom statsionare.

The formation of microflora on the laryngeal mucosa in newborn infants during the first 5 days of their life was studied in one of the maternity hospitals of Moscow. In this work modern methods of the isolation and identification of aerobic and anaerobic microorganisms were used, and the results thus obtained were computer-processed. In the maternity hospital of the "mother-child" type the microbial colonization of the laryngeal mucosa by normal and opportunistic microorganisms was noted in newborn infants. A wave-like course of the formation of laryngeal microflora, indicative of microbial succession occurring in the child, was revealed. The attempt to establish the cases of microbial interference between the species colonizing the laryngeal mucosa revealed that it was very rarely observed in 5-day-old newborns. This feature was seemingly the cause of low resistance of the larynx to colonization in newborn infants, which determined frequent colonization of their laryngeal mucosa with Staphylococcus aureus and Klebsiella.
