The results are presented of the comparative study of the presence of characteristic features of disorders of the microstructural organization of the test strain B. cereus ATCC 10702 cells by stable nanoparticles of silver, gold, platinum, zinc oxide and titanium dioxide with loss of cell viability during their interaction with nanoparticles in an aqueous medium using methods of bacteriology and electron microscopy. General size-dependent features of the effect of nanoparticles on B. cereus ATCC 10702 cells and differences associated with both the adsorption of metal oxide and noble metal nanoparticles on the surface of bacteria and the loss of viability of bacterial cells with different levels of their destruction, reaching 67-70 % in the case of nanoparticles noble metals, were found. The chemistry of the effects of silver, gold, platinum and zinc and titanium oxides nanoparticles on the test microbe B. cereus ATCC 10702 is considered. The assumption is made that the main feature of the interaction of nanodispersed structures based on noble metals and metal oxides is not associated with an increase in the specific contact surface of the dispersed phase, but with a significant increase in the specific surface energy, which leads to the modification of the multilayer hydrated water shells surrounding nanoparticles. The measured zeta (ζ-)-potential of metal and metal oxides nanoparticles characterizes the total effect formed on the diffusion-mobile boundary of the nanoparticle; its value is a quantitative characteristic of the equilibrium energy state of dispersed systems acting as biocatalysts of intracellular enzymes and causing hydrolysis of the polymer structures of cytoplasmic membranes and cell membranes and ultimately the death of microbial cells. The obtained experimental data can be used in creation effective antimicrobial compositions.
Keywords: microorganisms, Bacillus cereus АТСС 10702, biocidal activity, nanoparticles, zeta potential, disinfectant compositions.

Cationic surfactants based disinfectants have been widely used in practice for over 20 years. Despite the significant advances in analytical chemistry during this period, the determination of mixtures of several quaternary ammonium compounds in one disinfectant still causes certain difficulties. This work describes the separation in the combined presence of alkyldimethylbenzylammonium chloride, alkyldimethyl (ethylbenzyl) ammonium chloride, and dimethyldioctylammonium chloride in disinfectants using high performance liquid chromatography with a charged aerosol detector. The method was tested on model solutions and real disinfectants. The linearity range for alkyldimethylbenzylammonium chloride was from 0.03 to 0.17 %, for alkyldimethyl (ethylbenzyl) ammonium chloride – from 0.03 to 0.15 %, and from 0.01 to 0.11 % for dimethyldioctylammonium chloride. The calculated relative error of the method did not exceed 9 %. Thus, the proposed method can be used to analyze preparative forms of disinfectants containing these and other cationic surfactants.
Keywords: alkyldimethylbenzylammonium chloride, alkyldimethyl (ethylbenzyl) ammonium chloride, dimethyldioctylammonium chloride, disinfectants, HPLC, charged aerosol detector.

Retrospective analysis of developments on the use of sterilization packaging materials for medical devices (literature review)

G.N. Melnikova

Scientific Research Disinfectology Institute of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing: 18 Nauchny proezd, Moscow, 117246, Russian Federation.

The article discusses issues related to the creation and use of packaging materials for different types of products, including those specially designed for placing medical devices in them, before sterilization. The changes taking place related to the improvement of the barrier properties of packages to extend the preservation period of sterility of medical devices (both new types and complex in design) sterilized by different methods are noted. It is shown how over the course of several years new materials have been developed, technologies/methods of processing and reprocessing of raw materials and materials have changed, which make it possible to obtain packaging materials of different chemical nature and properties. Changes in existing packages from traditional materials (metal) to of single-use sterilization packages of a new generation with improved manufacturing technologies that provide mechanical, barrier and antimicrobial properties of packages differing in types, sizes, material properties are noted. The priority in the use of packaging materials for medical devices remains for materials that meet the requirements of GOST ISO 11607 "Packaging for medical devices subject to terminal sterilization", since the standard imposes more stringent requirements for the execution of packaging materials.
Keywords: sterilization packaging materials, sterilization boxes, medical devices, sterilization, sterilization methods, preservation of sterility.

A.M. Morozov, A.N. Sergeev, G.A. Dubatolov, N.A. Sergeev, S.V. Zhukov, T.S. Ryzhova, K.I. Khorak

Federal State Budgetary Educational Institution of Higher Education "Tver State Medical University" of Ministry of Healthcare of the Russian Federation: 4 Sovetskaya str., Tver, 170000, Russian Federation.

The aim – analyze modern Russian and foreign literary sources in order to determine modern means for treating the hands of the surgeon and the operating field. Results. One of the key points in the prevention of surgical infection is the treatment of the surgeon’s hands and the operating field with effective skin antiseptics in order to destroy pathogenic and opportunistic microorganisms that colonize intact skin. In modern practice, skin antiseptics are predominantly used containing alcohols as active substances, in particular ethyl, propyl and isopropyl, halogenated substances such as iodine and iodophores, guanidines, which include chlorhexidine digluconate, as well as quaternary ammonium compounds. Moreover, the most widespread are combined preparations containing several active substances and functional additives, which makes it possible to neutralize the negative properties of various active substances. Also, an interesting and promising direction is the use of polymer operating films or film-forming antiseptics. Currently, research is being actively carried out aimed at finding and developing modern highly effective antiseptic agents and their rational combinations that meet the necessary requirements, are optimal in their properties, cost-effective and comfortable to use.
Keywords: skin antiseptics, asepsis and antiseptics, surgical treatment of hands, treatment of the operating field.

The territory of the Saratov Region is situated predominantly in steppe area and is not among the constituent entities of the Russian Federation characterized by consistently high human infections with hemorrhagic fever (HFRS) incidence rates among the population. In certain years, extreme weather events in combination with good feeding and protective conditions result in hard to forecast outbreaks of the red vole numbers – main carrier of the hantavirus Puumala. Risk territories for intensive and extensive epizooty development are intra-zonal and azonal forest biotopes, to which recreation, residential areas and dacha settlements adjust. Epidemic complications on HFRS have been registered since 1960s. The outbreaks of the disease occurred in 1986, 1992, 1999, and 2014. Record-breaking as regards the number of cases outbreak was reported in 2019, associated with intensive sub-snow reproduction of the red vole during winter season. Intensive morbidity rate was 109.7 per 100 thousand of the population, which is tens of times higher than the long term average annual values (7.2). Under the given circumstances, a broad range of preventive measures was implemented, including additional monitoring investigations, restrictive, and sanitary-technical activities, outreach campaign, disinfection and deratization. As a result of the measures performed, incidence rates in the first half of 2020 was reduced to 5.7 per 100 thousand of the population. The lessons learned can help to avoid similar events in the region, other constituent entities that are enzootic in terms of this zoonosis. The results obtained should also be taken into account when monitoring other zoonoses relevant to the region, as well as on the territories of other subjects of the Russian Federation.
Keywords: hemorrhagic fever with renal syndrome, incidence rates among the population, prophylaxis, deratization.
