Disinfection of environmental objects against oocysts of coccidia of foxes and arctic foxes

Irkutsk region is among territories of intense industrial development. Considerable part of the regional population is long exposed to chemical pollutants of environmental objects. Th e authors evaluated carcinogenic risk for the population of industrial centers and rural area. Findings are that maximal carcinogenic risk is carried by the urban population. Aggregated carcinogenic risk parameters evaluation proved inhalation to be a priority route of exposure. Irkutsk region appeared to have territories with high carcinogenic risk for public health. Among a list of chemicals in the ambient air are priority carcinogens: six-valent chromium and lead. The evidences necessitate measures on the risks minimization. Due to absent data on carcinogens content of drinkable water in some rural area, the necessity is to evaluate risk for the rural population by studies of drinkable water quality that does not match hygienic regulations, because oral one is a main route of carcinogens intake.

The analysis of cases of detection of bacteria of the genus Aeromonas in clinical material from various loci of patients of medical organizations was carried out. Their species diversity, isolation in monoculture and associations, resistance to antibiotics and spring-autumn rises indicate the etiological significance of these microorganisms in the infectious process. To improve the biological safety of aquatic biotopes, it is important to study their microbiocenosis, in particular, the circulation of bacteria of the genus Aeromonas, in order to obtain information on pathogenic properties, antibiotic resistance, and seasonal fluctuations. To prevent the spread of Aeromonas infections, it is necessary to carry out sanitary and bacteriological studies of water bodies, environmental objects and food products.

Организации водопроводно-канализационного хозяйства в рамках технологических процессов водоотведения должны обеспечивать дезинвазию очищенных сточных вод и осадков, образующихся в результате их очистки. В соответствии с пунктом 1.2 СанПиН 3.2.3215-14 Профилактика паразитарных болезней на территории РФ , санитарные правила устанавливают требования к комплексу организационных, санитарно-противоэпидемических (профилактических) мероприятий, проведение которых направлено на предупреждение возникновения и распространения паразитарных заболеваний. Проведена оценка нормативных документов по дезинвазии объектов окружающей среды, а также решений по судебным делам в части ее проведения. Выявлены разногласия в документах по проведению дезинвазии, в связи с чем направлены обращения в различные организации с предложением гармонизировать правила с целью исключения разночтений. Изучены индустриальные методы дезинвазии осадка сточных вод. Показано, что происходит необоснованное навязывание препарата Бингсти .Within the frames of the wastewater disposal processes water and wastewater utilities shall provide for the disinvasion of effluents and wastewater sludge generated in the process of wastewater treatment. In accordance with paragraph 1.2 of SanPiN 3.2.3215-14 Prevention of parasitic diseases in the territory of the Russian Federation , the sanitary rules set out the requirements for a comprehensive set of organizational, sanitary and anti-epidemic (preventive) measures, that are aimed at preventing the occurrence and spread of parasitic diseases. The assessment of regulatory documents on the disinvasion of environmental objects, as well as judicial decisions regarding its implementation, was carried out. Controversies were revealed in the regulatory documents, and appeals were sent to various organizations with a proposal to harmonize the rules in order to exclude discrepancies. Industrial methods for disinvasion of wastewater sludge were studied. It is shown that there is an unreasonable aggressive selling of Bingsti ineffective product.

Prevention And Treatment

BACKGROUND: For today, the most important and discussed issue in the professional medical community is the problem of prevention and treatment of a new coronaviral infection (COVID-19). The main reason for the non-decreasing increase in morbidity and mortality is the absence of an etiotropic drug. In our study, it is proposed to use a previously available drug for the treatment of tick-borne encephalitis, ribonuclease A, obtained from the pancreas of cattle. AIM: The aim of investigation was to study the antiviral activity of RNаse A against SARS-CoV-2 in in vitro experiments. MATERIALS AND METHODS: The experiment used samples of 50 patients with a confirmed (by PCR) primary diagnosis of a new coronoviral infection COVID-19. The preparation for the study was served by ribonuclease A (neoFroxx GmbH, Germany) at a concentration of 0.5; 1; 5 and 10 mg/ml, incubated at 4 and 37C, the exposure was 20 minutes, 20 hours. A set of reagents OTT-PCR-RV-SARS-CoV-2 (Syntol, Russia) was used as test systems. RESULTS: of the current study is the revealed antiviral activity of ribonuclease A at a minmal concentration of 0.5 mg/ml during incubation from 20 minutes to 20 hours, in the temperature range of 437C. CONCLUSIONS: The data obtained in the in vitro study confirmed the ability of ribonuclease A to destroy viral RNA, which suggests the possible use of the drug both for the treatment of patients and for the treatment of environmental objects.

The special mobile diagnostic group (MDG) is formed in the Federal State Budgetary Establishment «33 Central Scientific Research Test Institute» of the Ministry of Defenсe of the Russian Federation (hereinafter referred to as the institute) to perform tasks related to the radiation and chemical (RCh) control of different objects, to ensure RCh safety and security of mass events, as well as to perform special tasks of RCh examination of samples of all kinds. The purpose of the work is to consider the design, capabilities and organization of the mobile complex of chemical control (MCCC), which is the basis of the technical equipment of the MDG. The complex is created on the basis of Ford-Transit off-road vehicle with the equipment for the MDG and a container installed on a two-axle platform, where the equipment for the MDG is located. The complex is equipped with modern analytical equipment, means of communications, navigation, information processing and automatic meteorological observation, with the life support kit, autonomous power and water supply systems, exhaust ventilation, heating and air conditioning systems. The technical characteristics of the MCCC are as follows: crew – 8 people; preparation time – no more than 60 minutes; time for the preliminary identification of substances detected by the mobile group (from the moment of arrival) – no more than 60 minutes; the lower limit of detection of toxic chemicals in environmental objects – at the maximum concentration limit; time of confirming identification of detected toxic chemicals (from the moment of delivery of samples) – no more than 180 minutes; cruising range – up to 700 km. The methodological apparatus is also developed, that ensures the functioning of the MCCC crew during the performance of wide range of tasks of the MDG. Subsequently, this methodological apparatus has been repeatedly expanded and refined based on the results of the complex's participation in ensuring the RCh security of various mass events. The algorithm of carrying out special chemical control by technical means of the MCCC complex is presented in the article. The complex is capable of detecting both low-hazard and emergency concentrations of practically all known toxic chemicals in various samples, and identifying these substances in environmental objects.
