Abstract.
Introduction. One of the major challenges of modern medicine is antibiotic resistance of hospital acquired infection pathogens. Thus, the detailed study of the mechanisms of their evolution is of a high importance.
The aim of the study was to evaluate the role of temperate bacteriophages circulating in hospital environment on the biological features of hospital acquired infection bacterial pathogens.
Materials and methods. The study was conducted in a number of medical facilities (surgical, traumatological, urological, oncological and burn departments, neonatal intensive care units). Isolation of hospital acquired infection bacterial strains was carried out in accordance with generally accepted bacteriological methods. Isolation of phages from clinical samples was carried out according to generally accepted methods, but in authors modification. Statistical analysis was performed using Statistica and WinPepi software.
Results. A strong correlation was revealed between the incidence of hospital acquired infection caused by E. coli and the intensity of E. coli circulation with prophage gene c2418, weak positive relationship was observed between the incidence of urinary tract infections and isolation rate of Enterococcus spp. with phage genes gp2 and yopX, a strong correlation was noted between the incidence of S. aureus HAIs and the intensity of circulation of temperate phages of S. aureus in the hospitals, a strong positive relationship was revealed between the activity of the circulation of Pseudomonas phages in the hospitals and the dynamics of P. aeruginosa hospital acquired infections.
Conclusion. It was established a significant role of temperate bacteriophages in evolution of pathogenic capacity of hospital acquired infection bacterial pathogens. Temperate bacteriophages promote the acquisition of important biological properties by hospital strains:  increased virulence and ability to epidemic spread, multiple resistance to antibiotics, disinfectants and antiseptics.

Abstract
Introduction. The preservation of reproductive health in women and the realization of their reproductive potential is largely determined by the body’s aging rate. Defining the risk of premature body aging based on somatometric and clinical indicators is a promising method of personalized prevention.
The aim of the study was to identify the correlation of somatometric and clinical indicators with biological age and the aging rate of women of three age periods.
Materials and methods. It was examined 320 women of the indigenous (Mongoloids – Khakass) and alien (European – Russian) population of the Republic of Khakassia aged 21 to 55 years. They were measured the length and body weight; chest circumference and buttocks; shoulders and pelvis diameter; by calculation was determined the body mass index, biological age and coefficient of the aging rate; ROC statistical analysis was used to identify signs affecting the body's aging rate with an assessment of the methods diagnostic effectiveness (sensitivity, specificity, accuracy, prognostic significance), and to identify the level of quantitative diagnostic criteria using the calculation of chance and odds ratio.
            Results. The body’s accelerated aging rates revealed in 77,8% of Europeans and 37,5% of Khakass (p=0,005). In Europeans, the following indicators are associated with the risk of body’s accelerated aging: body mass index ≥ 25 kg/m2 (odds ratio criterion–65,4); chest circumference ≥ 85,5 cm (odds ratio –38,1); the duration of the menstrual cycle ≥ 30 days or more (odds ratio –4,1); pelvic diameter ≥ 27,5 cm (odds ratio –4,2). For Khakass-women with the risk of body’s accelerated aging, the following values are associated: body mass index ≥ 24,7 kg/m2 (odds ratio –27,3); chest circumference ≥ 89,5 cm (odds ratio –41,7); pelvis diameter ≥ 26,5 cm (odds ratio –5,0).
Conclusions. The use of the obtained data allow to form the risk group for women with conditions affecting the reproductive system for the timely correction.

Abstract
Introduction. Blastocystis spp. widespread intestinal protozoa of humans and animals. Approaches to the preventive measures’ development require theoretical justification including the information on the genetic diversity of Blastocystis spp.
The aim of the study was to assess of the genetic diversity of Blastocystis spp. circulating in the territory of two geographically distant subjects of the Russian Federation.
Materials and methods. It was performed the genetic subtyping of 144 blastocyst isolates obtained from residents of Saint-Petersburg (117 samples) and the Chukotka Autonomous Area (27 samples) using two methods: PCR with STS primers and fragment sequencing of the small subunit ribosomal RNA gene (Barcoding).
Results. The distribution of isolates by subtype was as follows: St. Petersburg: ST1 - 33 (28.7%), ST2 - 33 (28.7%), ST3 -32 (27.8%), ST4 -1 (0.9 %), ST7 - 2 (1.7%), ST2 + ST3 - 1 (0.9%), it wasn’t determined a subtype of 13 (11.3%), nonspecific amplification was observed in 2 samples; Chukotka Autonomous Area: ST1 - 6 (22.2%), ST2 - 5 (18.5%), ST3 -7 (25.9%), ST4 -1 (3.7%), ST7 - 1 (3, 7%), it wasn’t determined a subtype - 7 (25.9%).
Conclusion. The obtained data confirm the presence of genetic heterogeneity of Blastocystis spp. circulating among the population of Russia. Moreover, the absence of significant differences in the structure of the subtype’s distribution, both between the two analyzed regions and worldwide, indicates the global nature of the epidemic process of Blastocystis spp. The results of blastocysts genetic subtyping should be considered while preventive measures implemented.

Abstract
Introduction. The main reasons for considering oil industry employees to be a group with a high risk of general and occupational diseases are: the impact of a complex of harmful factors in the work environment, the work process along with adverse climatic conditions.
The aim of the study was to performa comparative analysis of the questionnaire results of oil industry employees working under conditions of intense exposure to cold environment in order to analyze their self-rated health, to identify risk factors and events leading to its deterioration, and to analyze the contribution of production factors to health status.
Materials and methods. It wassurveyed 596 employees of an oil company of various professional groups in comparison with a control group consisting of administrative and managerial staff. The use of the developed questionnaire allow to assess the employees’ health status of various professional groups, and to determine the risk factors when working in the open area in the cold season.
Results. According to the questionnaire results, it was found that employees working in cold environment have the proven risk of the following pathologies development: musculoskeletal disorders, skin disorders, psychoemotional disorders. The majority of occupational groups mainly associate their illnesses with cold environment. Employees, who expose to severe cold while working, are more likely to suffer from respiratory infections. Significant risk factors for the diseases development during cold exposure are smoking and alcohol. The questionnaire results reveal the metabolic disorders (increased body weight and obesity) in the exposed group, which is considered as a cold adaptation factor. At the same time, a significant number of employees believe that special clothing does not offer an adequate level of cold protection. Humid clothes are a significant risk factor while working in the open area for the development of cold-related diseases.
Conclusion. According to the questionnaire resultsand risk factors for health disorders in the result of the adverse climate environment were proposed medical and preventive measures.
