[Organization and epidemiological surveillance of Western Nile fever in case of the Volgograd Region].

Western Nile fever (WNF) is an arboviral infection of the most relevance to the Volgograd Region. The observed decreasing incidence of WNF in 2001-2006, 2008, and 2009 and a decline in the number of its severe forms are only suggestive of the temporary regression of the epidemic process in the Volgograd Region. There are prerequisites and forerunners for a complication of the epidemiological Western Nile fever situation in the Volgograd Region.

[Disinfectology as molecular-epidemiologic direction of infection control].

Specific aims of environment biologic pathogen control by applying special disinfectologic means and technologies are formulated. The main components of disinfectologic process are examined: molecular-biologic properties of targets--their sensitivity (resistance) to biocidal agents; biocidal molecular-chemical properties of disinfection means; toxicological properties of the latter by their effect on human organism as the object of epidemiologic protection. Perspectives of improvement of disinfectologic technologies by using composition potential of different actively operating molecular substances are discussed.

[Chemical safety as a problem of epidemiology of non-infectious diseases].

Based on the analysis of adopted in sanitary science methodology for the study and evaluation of the biological action and hygienic significance of environmental factors there was shown the need for the use of laws and methodology of classical epidemiology to ensure the chemical safety in the recognition and elimination of the group of diseases of chemical etiology, outbreaks of similar non infectious diseases. It is stated that individually small "non-toxic" doses of chemicals, but "loading" a large population and forming a large collective dose apparently can be implemented in a stochastic population health damage, detectable only on the basis of large-scale epidemiological studies to assess the risk. These approaches are presented to be especially important for agents in the environment, optimal for which is not absence, but the presence for provision of necessary target effect (pesticides, disinfectants and other household products, etc.

[Disinfectology and disinfection activity--basis of nonspecific prophylaxis of infectious diseases].

The necessity of further development of disinfectology as a branch of science that studies regularities of nonspecific prophylaxis of infectious and parasitic diseases by impact on pathogenic biological objects and their carriers is justified. The importance and topicality of nonspecific prophylaxis of infectious diseases, the necessity to take into account significant factors that characterize epidemic process during selection and application of means and methods of nonspecific prophylaxis are specified. Data that are necessary to be taken into account during development of means, methods and technologies of disinfectologic prophylaxis of infectious and parasitic diseases are presented.

Guided self-assembly of electrostatic binary monolayers via isothermal-isobaric control.

Self-assembly of a binary monolayer of charged particles is modeled using molecular dynamics and statistical mechanics. The equilibrium phase diagram for the system has three distinct phases: an ionic crystal; a geometrically ordered crystal with disordered charges; and a fluid. We show that self-assembly occurs near the phase transition between the ionic crystal and the fluid, and that the rate of ordering is sensitive to the applied pressure.

[Improving the planning of sanitary and epidemiological institutions under current conditions].

It is shown that valid annual planning of the activities of the State Epidemiological and Sanitary Control Service oriented on social well-being parameters helps determine the role of each specialist of the staff, the scope of the measures and their sequence, thus warranting effective work of the service.

[Laboratory support of the State Sanitary and Epidemiologic Service under the new socioeconomic conditions].

Structural and functional changes in the system of laboratory provision of the State Sanitary and Epidemiological Service under modern economic conditions had a positive impact on the number and quality of laboratory studies. The concept of rearrangement of laboratory service for the period of up to the year 2000 and its staff and material provision improved the quality of laboratory work and eventually the quality of sanitary epidemiological surveillance at the very first stages of its realization.

[Provision of information on the activities of the State Sanitary-Epidemiologic Service].

Use of a multi-level automated information system has been scientifically validated for the State Sanitary Epidemic Surveillance Service of the Russian Federation in recent years. Such a system ensures rapid collection, processing, and analysis of information on the sanitary and epidemic status of the population, activities of sanitary and epidemiological institutions, prediction and simulation of sanitary epidemic situations, management of the service. It helped automate the routine processes of professional, financial, and managing activities of the service institutions.

[Organizational technologies and management of the organs and institutions of the State Sanitary and Epidemiological Surveillance in the Russian Federation].

The authors offer a scientifically-based rationale for the system of management of the State Sanitary and Epidemiological Service and its institutions under modern socioeconomic conditions in Russia. Organizational models of the structure of State Sanitary and Epidemiological Surveillance Centers are offered and their functions determined for various levels of management. A concept of development and organizational structure of the service and its institutions is proposed, aimed at provision of sanitary and epidemiological well-being in the Russian Federation.

[Microbial ecology and a retrospective assessment of the possibility of predicting an outbreak of suppurative meningitis caused by a Serratia marcescens strain in a hospital for the nursing care of premature infants].

An outbreak of purulent meningitides in a hospital ward for preterm babies, caused by Serratia marcescens strain of serovar 05/13 with multiple resistance, is described. Data on the results of the long-term observation of the ward showed that during three months preceding the outbreak the consecutive spread of the infective strain and its colonization of the intestine of children occurred. At the moment of the outbreak S.

[Work experience of the Minsk City Epidemiological Health Station in organizing a system for the epidemiological health surveillance of infectious diseases].

The system of the sanitary and epidemiological surveillance of infectious diseases comprises three aspects: supply of information, epidemiological and sanitary-hygienic surveillance. The system ensures the reliable epidemiological diagnosis, close collaboration in the work of specialists of sanitary and epidemiological departments, the differentiated surveillance of epidemiologically important objects, and the effectiveness of measures aimed at decreasing the infectious diseases incidence rates.
