[Ab] Resumo:The aim is the study of the circulation, biological activity, persistent potential and genotypic characteristics of opportunistic Enterobacteriaceae of microbial community of the Lena River which is the one of the largest sources of water in Russia and Siberia. Gram-negative component of microbial community in the Lena River was mainly represented by Enterobacteriaceae (80%), including dominated Escherichia (dominant class) and Enterobacter and Klebsiella (subdominant class). In conditions of anthropogenic pollution there is a reorganization of microbial community of the Lena River in the direction of the increase in the proportion of opportunistic pathogens, their species diversity; there is a change of the biological activity of microorganisms, gains of share of strains characterized by antilysozyme activity, hemolytic activity, production DNase, phosphatase. The parameters of system "lysozyme-antilysozyme" are changing, the frequency of the occurrence of bacteria with antilysozyme activity is increasing. This shows the restructurization of the microbial community of water objects. Microorganisms of water objects in territories of anthropogenic pollution are characterized by multiple antibiotic resistance. The proportion of gram-negative opportunistic Enterobacteriaceae in microbial communities of water ecosystems determines the potential danger of water objects and the impact on the level of antibiotic resistance of bacteria. Opportunistic Enterobacteriaceae of microbial community of the Lena River near the city of Yakutsk are characterized by the presence of genetic determinants of pathogenicity (hlyA and sfaG). This is indicative of their potential epidemiological relevance. Microorganisms with high biological activity are markers of their epidemiological danger.

[Ab] Resumo:The increasing chemicalization of production and life leads to the pollution of water bodies by chemicals, the effect of which on the micro - and macro - organisms is poorly understood. This section of the study in sanitary bacteriology is becoming ever more topical and is an important task of modern hygienic science. One of complicacies of the study of the problem is related with the fact that the presence of only experimental data fails to be sufficient, as the impact of any given chemical substance on different bacteria in the experiment does not mean that under natural conditions, similar results will be obtained. One reason for this may be the inhibitory effect of the given chemical on biological properties of bacteria, while in field conditions in the water several chemicals interacting with each other can exist. In this regard, the aim of the work was to assess the indicator value of sanitary and microbiological indices of epidemic hazard of water use in conditions of chemical pollution of surface water bodies.

[Ab] Resumo:There are considered special social and economic aspects of the epidemiology of Helicobacter pylori. These aspects acquired the particular importance for the last time due to the fact that the provision of the people with pure water has been becoming the focus of the attention of geopolitical and socio-economic interests in a number of countries. The availability ofpure drinking water serves a marker of the socio-economic state of the territory and the population living there. In Russia where different climatic conditions are deposited by considerable regional differences in the conditions of communal services caused both by various level of the socio-economic development of the territory, the supplementation with pure drinking water serves as the social determinant of the ecological conditions of the population's life. This particularly has impact on the unfeasible technical state of the water distribution systems, microorganism ecology of which can substantially affect public health. The performed by authors a specialized screening ofpresented at the official web site of the joint-stock company «Mosvodokanal¼ current data concerning the quality of drinking water consumed by 2500 Moscovites, tested for the Helicobacter pylori infection revealed no deviations from the sanitary standards in the water received by the consumers. Along with that, the comparison of the map documents of the distribution of the Helicobacter pylori infection in Moscow with the distribution of citizens' complaints of the decline of the quality of tap water has revealed a territorial fastening of the high values of the population infection rate of n^ylori and the urban sites with the greatest number of complaints. In the microbial ecology of water-distribution systems there are tightly aligned problems of their epidemiological safety, technical state and economic damage caused by corrosion as a result of microbiotic activity. In contrast to acute bacterial and viral infections which are deemed of the greatest importance when assessing the sanitary condition of water sources and water-distribution systems, the consequences of infection with H. pylori may not be manifestedfor a long time but some years later they may be manifested as serious chronic diseases (from gastritis to adenocarcinoma of the stomach and a wide range of extraintestinal pathologies), which causes great social and economic losses. Thus, the socio-economic aspect of the epidemiology of helicobacteriosis includes at least two components: the technic - the maintenance of the feasible technic and sanitary state of the water distribution systems and the medico-social - expenditures for screening and treatment of infected patients. In total they are an inseparable part of the prevention of socially-important diseases in the public health system.

[Ti] Título:17α-Ethynylestradiol biodegradation in different river-based groundwater recharge modes with reclaimed water and degradation-associated community structure of bacteria and archaea.

[Ab] Resumo:This study investigated 17α-ethynylestradiol (EE2) biodegradation process and primary metabolic pathways associated with community structures of microorganism during groundwater recharge using reclaimed water. The attenuation rate is 1.58 times higher in wetting and drying alternative recharge (WDAR) than in continual recharge (CR). The primary biotransformation pathways of EE2 in WDAR system began with the oxidation of C-17 on ring D to form a ketone group, and D-ring was subsequently hydroxylated and cleaved. In the CR system, the metabolic pathway changed from the oxidation of C-17 on ring D to hydroxylation of C-4 on ring A, and ring A or B subsequently cleaved; this transition was related to DO, and the microbial community structure. Four hundred fifty four pyrosequencing of 16s rRNA genes indicated that the bacterial communities in the upper layer of the WDAR system were more diverse than those found in the bottom layer of the CR system; this result was reversed for archaea. Unweighted UniFrac and taxonomic analyses were conducted to relate the change in bacterial community structure to the metabolic pathway. Microorganism community diversity and structure were related to the concentrations of dissolved oxygen, EE2 and its intermediates in the system. Five known bacterial classes and one known archaeal class, five major bacterial genera and one major archaeal genus might be involved in EE2 degradation. The findings of this study provide an understanding of EE2 biodegradation in groundwater recharge areas under different recharging modes and can facilitate the prediction of the fate of EE2 in underground aquifers.

[Ab] Resumo:The paper presents experimental data on the pesticides action (molinate (OrdramA), Dinitroortocresolum and chlorophos) at concentrations of 0.01 mg /l to 10 mg/l on sanitary-indicative (TBC, total coliform bacteria, E. coli, E. faecalis), potentially pathogenic ( Ps. aeruginosa) and pathogenic (S. Derby) microflora of the river water. As the test cultures there were used isolated from the reservoir and museum strains of microorganisms. Due to the fact that the rate of decomposition ofpesticides in water increases in direct proportion to the extent of its biological contamination, the experiments were performed with the river water: native and sterilized by autoclaving. There were identified species and strain differences in the microbial response to the action of pesticides. The selectivity of OrdramA action at a concentration of 0.1 to 10 mg/l on Salmonella and of chlorophos at a concentration of 10 mg/l for Salmonella and E. coli is manifested in the stimulation of the reproduction of these bacteria. Dinitroortocresolum in concentrations of 10 mg/l and 1 mg/l gives rise in the reproduction of Pseudomonas aeruginosa and inhibits the growth of total coliform bacteria and E. coli, in a concentration of 0.1 mg/l the preparation stimulates the viability of all the studied microorganisms. When entering the body of water, pesticides were found to cause changes of biocenosis in the river water and disturb bacterial self-cleaning processes. In conditions of pesticide pollution total coliform bacteria, E. coli and E. faecalis unable to maintain their indicative value and therefore the use of only them for the evaluation of the sanitary-epidemiological status of the water source appears to be insufficient. Due to the fact that the epidemic potential of water is directly dependent on quantitative content ofpathogenic and opportunistic pathogenic microorganisms in it, the reproduction Salmonella and Pseudomonas bacteria is a negative moment from the sanitary and epidemiological point of view.

[Ab] Resumo:The used methodology of the scientific substantiation of indicators is in the establishment of the conformity of laws of vital activity of indicator and pathogenic microorganisms in the real conditions of the action of the complex of factors, including disinfecting agents. In the one water sample simultaneously there were determined both the general indicator (GICB), thermotolerant (TTCB), glucose positive (GPCB) coliform bacteria, E.coli. On the base of long-term research in the various regions of the Russian Federation, as well with bearing in mind the analysis of domestic and foreign data, comparing the water quality and the incidence of intestinal infections in population it is recommended to use the index of determination of the total number glucose positive coliform bacteria (GPCB), which brings together a much broader range of bacteria of the Enterobacteriaceae family in comparison with total coliform bacteria (TCB) and thermotolerant coliform bacteria (TTCB) and warrants the absence in the test volume of water as an indicator lactose positive (E.coli, TCB, TTCB) and pathogens (salmonella) and potentially pathogenic bacteria which do not ferment lactose. Proposed index of GPCB is shown to allow to assess epidemiological risks not only more accurate, but also more efficiently without increasing the cost performance of bacteriological research.

[Ab] Resumo:There was developed a liquid storage medium for the isolation of bacteria of genus Salmonella from water bodies (The culture medium for the accumulation of Salmonella, ready to use, "RNS"), providing the accumulation of Salmonella from different serogroups, inhibiting the growth of accompanying microflora, allowing to obtain objective information about the extent of bacterial contamination of water bodies. Medium is by nature of a solution for microbiological purposes which is produced by mixing the components with consequentfiltration and sterilization. In an experimental way there were chosen optimal ratios of the nutrient medium ingredients: extract offodder yeast in an amount of 4.55.0 g/l, sodium hydroxide - to 1.3-1.4 g/l, potassium phosphate - 8.6-8.8 g/l. The medium is a sterile, clear liquid, green in color, medium pH is 6.4 to 6.8, amine nitrogen - from 0.05 to 0.1%. Designed medium for accumulation is sensitivity, it ensures the growth of the test strains of salmonella at seeding of single cells in that favorably differs from similar media used in public health practice at the present time. The smallest time for the accumulation of biomass of Salmonella accounts of 6 hours, the optimal time is 24 hours. Incubation of crops is produced at 37 °C. Cultures of Salmonella at seeding in the developed medium retain their biological properties. Developed medium in terms of sensitivity is superior to magnesian and selenite media.

[Ab] Resumo:There remains a pressing need for systematic water quality monitoring strategies to assess drinking water safety and to track progress towards the Sustainable Development Goals (SDG). This study incorporated water quality testing into an existing national socioeconomic survey in Yogyakarta province, Indonesia; the first such study in Indonesia in terms of SDG tracking. Multivariate regression analysis assessed the association between faecal and nitrate contamination and drinking water sources household drinking water adjusted for wealth, education level, type of water sources and type of sanitation facilities. The survey observed widespread faecal contamination in both sources for drinking water (89.2%, 95%CI: 86.9-91.5%; n=720) and household drinking water (67.1%, 95%CI: 64.1-70.1%; n=917) as measured by Escherichia coli. This was despite widespread improved drinking water source coverage (85.3%) and commonly self-reported boiling practices (82.2%). E.coli concentration levels in household drinking water were associated with wealth, education levels of a household head, and type of water source (i.e. vender water or local sources). Following the proposed SDG definition for Target 6.1 (water) and 6.2 (sanitation), the estimated proportion of households with access to safely managed drinking water and sanitation was 8.5% and 45.5%, respectively in the study areas, indicating substantial difference from improved drinking water (82.2%) and improved sanitation coverage (70.9%) as per the MDGs targets. The greatest contamination and risk factors were found in the poorest households indicating the urgent need for targeted and effective interventions here. There is suggested evidence that sub-surface leaching from on-site sanitation adversely impacts on drinking water sources, which underscores the need for further technical assistance in promoting latrine construction. Urgent action is still needed to strengthen systematic monitoring efforts towards tracking SDG Goal 6.

[Ab] Resumo:In this study, New Delhi metallo-beta-lactamase (NDM)-producing Enterobacteriaceae were identified in Irish recreational waters and sewage. Indistinguishable NDM-producing Escherichia coli by pulsed-field gel electrophoresis were isolated from sewage, a fresh water stream and a human source. NDM-producing Klebsiella pneumoniae isolated from sewage and seawater in the same area were closely related to each other and to a human isolate. This raises concerns regarding the potential for sewage discharges to contribute to the spread of carbapenemase-producing Enterobacteriaceae.

[Ab] Resumo:Assessment of water quality status of 7 sites of Kavvayi Wetland in northern Kerala (India) was carried out. The physico-chemical, bacteriological and biological parameters were monitored during pre-monsoon, monsoon and post-monsoon seasons. Canadian Council of Ministers of the Environment (CCME) water quality index of the Kavvayi Lake samples ranged from 43.99-44.77; indicating that water quality was threatened or impaired. The poor water quality status might be due to dumping of wastes from municipal and domestic sources and agricultural runoff. Biological water quality criteria (BWQC) determined for wetland revealed that stations such as mixing point of Kariangode River into Kavvayi Lake and Kottikkadavu was moderately polluted in pre-monsoon and post- monsoon seasons. Mixing point of Nileswar River into Kavvayi Lake was moderately polluted in pre-monsoon season. Both calculated indices suggest that quality of lake was found to be influenced by anthropogenic activities such as unscientific tourism and infrastructure development, land encroachment, sand mining, pollution etc. The study was carried out as part of a programme, which aimed to conserve Kavvayi wetland because of its unique ecological and environmental characteristics.
