[Characterization of the biological properties of enterococci of different origin].

The species composition of enterococci isolated from different ecological niches in newborn infants was determined. Pathogenicity and persistence markers were unified into a single complex which integrally determined the pathogenic potential of enterococci. The mathematical model suitable for differentiation pathogenic and nonpatogenic enterococci was developed.

[Characteristics of the population and subpopulation composition of peripheral blood lymphocytes in noncomplicated pregnancy based on flow cytofluorometry data].

The population and subpopulation composition of peripheral blood lymphocytes of 33 women was studied in the dynamics of non-complicated pregnancy by the method of flow cytofluorometry with the use of equipment and reagents supplied by Becton Dickinson, Inc. This study revealed that the non-complicated course of pregnancy was characterized by the adequate reaction of the mother's immune system ensuring the physiological development of the fetus during pregnancy and timely labor.

[Pathogenicity factors of Corynebacterium diphtheriae circulating in the Primorski region under conditions of mass immunization of population].

The study of the main pathogenicity factors of C. diphtheriae (adhesive activity, toxigenicity, detection of tox+ gene) circulating in the Primorski Territory has been made. As revealed in this study, at the period of declined epidemic process due to mass immunization of the adult and child population against diphtheria the selection of C.

[Cesarean section as a means of prevention of child disability].

Analysis of the results of operations performed at the Ural Institute of Maternal and Neonatal Health Protection in 1988-1998 showed that women with high-risk pregnancy are purposefully hospitalized at the Perinatal Center, and therefore high percentage of abdominal deliveries is justified, because this operation is aimed at prevention of disabling diseases of the central nervous system in newborns and infants.
