    The coliform bacteria group consists of several genera of bacteria belonging to the family enterobacteriaceae. These are harmless bacteria, mostly live in soil, water, and digestive system of animals. Fecal coliform bacteria, which belongs to this group, are present in large numbers in feces and intestinal tract of human beings and other warm-blooded animals which can enter into water bodies from human and animal waste. Swimming in water having high levels of Fecal coliform bacteria increases the chance of developing illness (fever, nausea or stomach cramps) from pathogens entering the body through mouth, nose, ears or cuts in the skin. The objective of the present study was to characterize the bathing quality of Pakistani coastal water with respect to coliform bacteria. Total and Fecal coliform bacteria were determined at seven different locations along Pakistan coast using membrane filtration (MF) technique. 100 ml of water was passed through 0.45 micron (mu) filter paper. These filter papers were put on pads, soaked in Lauryle sulphate broth in petri-dishes and incubated at 44 deg. C for Fecal and 37 deg. for Total coliform for 24 hours. Significantly high population of Fecal and Total coliform bacteria was recorded at Karachi harbour area and Indus delta region. Results indicate that a large amount of domestically originated waste is being discharged into these locations without any pre-treatment (e.g., screening, activated sludge, by using filtration beds etc.) resulting in a poor seawater quality making it unfit for bathing.

    The present work evaluated the performance of two treatment systems in reducing indicators of biological contamination in swine production wastewater. System I consisted of two upflow anaerobic sludge blanket (UASB) reactors, with 510 and 209 L in volume, being serially arranged. System II consisted of a UASB reactor, anaerobic filter, trickling filter, and decanter, being also organized in series, with volumes of 300, 190, 250, and 150 L, respectively. Hydraulic retention times (HRT) applied in the first UASB reactors were 40, 30, 20, and 11 h in systems I and II. The average removal efficiencies of total and thermotolerant coliforms in system I were 92.92% to 99.50% and 94.29% to 99.56%, respectively, and increased in system II to 99.45% to 99.91% and 99.52% to 99.93%, respectively. Average removal rates of helminth eggs in system I were 96.44% to 99.11%, reaching 100% as in system II. In reactor sludge, the counts of total and thermotolerant coliforms ranged between 105 and 109 MPN (100 mL)−1, while helminth eggs ranged from 0.86 to 9.27 eggs g−1 TS. PMID:24812560

    Full Text Available A cross-sectional study in four swine feed mills aimed to evaluate the correlation between the score of the inspection checklist defined in the Normative Instruction 4 (IN 4/ Brazilian Ministry of Agriculture, Livestock and Food Supply, and the enumeration of total coliforms throughout the manufacturing process. The most of non-conformities was found in the physical structure of the feed mills. Feed mill B showed the lowest number of unconformities while units A and D had the largest number of nonconformities. In 38.53% (489/1269 of the samples the presence of total coliform was detected, however no significant difference in the bacterial counts was observed between sampling sites and feed mills. The logistic regression pointed higher odds ratio (OR for total coliforms isolation at dosing (OR = 9.51, 95% CI: 4.43 to 20.41, grinding (OR = 7.10, 95% CI = 3.27 to 15.40 and residues (OR = 6.21, 95% CI: 3.88 to 9.95 In spite of having the second score in the checklist inspection, feed mill C presented the highest odds for total coliforms isolation (OR= 2,43, IC 95%: 1,68-3,53. The data indicate no association between the score of checklist and the presence of hygienic indicators in feed mills.

    Full Text Available This study was aimed to evaluate the performance of SSF in removing bacteria (Total Coliforms and E. Coli in regard to grain size distribution and grain shape intermittently. Two methodological approaches used in this reasearch were literature review and laboratory work. Bacteria removal was analyzed considering two different filter media (Rhine sand-spherical shape and Lava sand-angular shape with three different grain size distributions. The best performance was attained by filter column F4 which consisted of Lava sand and had the configuration C2 (d10 = 0.07 mm; Cu = 4.2. This filter column achieved 4.7log-units removal of Total Coliforms and 5.0log-units removal of E. coli. The results show that a smaller grain size and an angular shape of sand grain lead to an increase in bacteria removal.

    Full Text Available Readycult[tm] - LMX is a rapid method to test for the presence of total coliform bacteria and Escherichia coli in water, giving results in 24h. It is based on reactions of specific microbial enzymes or indicator nutrients of the medium. The goal of this paper was to study the use of Readycult[tm] - LMX to detect total coliform and E. coli in milk. One hundred twenty five samples of pasteurized and raw milk, collected in Londrina, PR, Brazil, were tested simultaneously by the most probable number (MPN method using Brilliant Green Bile Lactose Broth (2% (BRILA and Readycult[tm] - LMX. The Readycult[tm] - LMX test was evaluated for sensitivity, simplicity, and speed of results. There was a significant correlation between the results obtained by the two methods for total coliforms (r: 0.8224 and for E. coli (r: 0.8603. The two methods yielded similar results, but Readycult[tm] - LMX was easier to use. In addition, results were available as early as 24h.

    Full Text Available Electrocoagulation is an electrochemical method for the treatment of water and wastewater. The present cross-sectional study was designed to investigate the removal efficiency of total coliform and heterotrophic bacteria from surface water using the process. For this purpose, water samples were taken from the drinking water intake at Suleiman-Shahsonghur Dam. The electrocoagulation process was carried out in a Plexiglas reactor in the batch mode with Al and Fe used electrodes. The experiment design was carried out using the Design Expert Software (Stat-Ease Inc., Ver. 6.0.6. After each run, the values of metals dissolved due to anode electrode dissolution were measured using the Inductively Coupled Plasma (ICP and the results were analyzed using the RSM model. Results revealed maximum removal efficiencies of 100% and 89.1% for total coliform and heterotrophic bacteria using the Al electrode, respectively. Also, maximum removal efficiencies using the Fe electrode for the same pollutants were 100% and 76.1%. The measurements clearly indicate that the quantities of Al and Fe released in water were higher than the recommended values. While the electrocoagulation process showed to be effective in removing microbial agents from surface waters, the high concentrations of dissolved metals due to the dissolution of the anode electrode seem to remain a health problem that requires optimal conditions to be determined for acheiving standard concentrations of the dissolved metals.

    River water quality in rapidly urbanising Asian cities threatens to damage the resource base on which human health, economic growth and poverty reduction all depend. Dhaka reflects the challenges and opportunities for balancing these dynamic and complex trade-offs which goals can be achieved through effective policy interventions. There is a serious problem of water pollution in central Dhaka, in the Turag-Tongi-Balu River system in Bangladesh with the river system being one of the most polluted in the world at the moment. A baseline survey of water chemistry and total coliforms has been undertaken and shows dissolved oxygen close to zero in the dry season, high organic loading together with extreme levels of Ammonium-N and total coliform in the water. Models have been applied to assess hydrochemical processes in the river and evaluate alternative strategies for policy and the management of the pollution issues. In particular models of flow, Nitrate-N, Ammonium-N and indicator bacteria (total coliforms) are applied to simulate water quality in the river system. Various scenarios are explored to clean up the river system, including flow augmentation and improved effluent treatment. The model results indicate that improved effluent treatment is likely to have a more significant impact on reducing Ammonium-N and total coliforms than flow augmentation, but a combined strategy would greatly reduce the pollution problems in the Turag-Tongi-Balu River System.

The chicks broiler were treated with 0.04% antibiotics and 1% Spirulina plantensis as a prebiotic under different interval ingestion. This experiment was constructed under completely random design (CRD with 4 treatments and 5 repetition. The treatment that was applied were T0 (Poultry feed + 0.04% Zinc bacitracin, T1 (Poultry feed + 1% throughout 7 days, T2 (Poultry feed + 1% throughout 21 days, and T4 (Poultry feed + 1% throughout 35 days. The parameter measurements conducted in the 32nd day with random sampling from each experiments. Total amount of lactic acid and coliform from each samples were observed and the variance was with 5% accuration. The result showed the total amout of Coliform in ileum was significantly different (P<0.05 in the other hand the total amount of Coliform and acid bacteria in caecum were not influenced (P<0.05. It can be inferred that the Spirulina platensis treatment for 3 weeks reduced the total amount of bacteria inside caecum and ileum.

    Rizzo, Luigi

    2009-01-01

    In this study the potential application of TiO 2 photocatalysis as primary disinfection system of drinking water was investigated in terms of coliform bacteria inactivation and injury. As model water the effluent of biological denitrification unit for nitrate removal from groundwater, which is characterized by high organic matter and bacteria release, was used. The injury of photocatalysis on coliform bacteria was characterized by means of selective (mEndo) and less selective (mT7) culture media. Different catalyst loadings as well as photolysis and adsorption effects were investigated. Photocatalysis was effective in coliform bacteria inactivation (91-99% after 60 min irradiation time, depending on both catalyst loading and initial density of coliform bacteria detected by mEndo), although no total removal was observed after 60 min irradiation time. The contribution of adsorption mechanism was significant (60-98% after 60 min, depending on catalyst loading) compared to previous investigations probably due to the nature of source water rich in particulate organic matter and biofilm. Photocatalysis process did not result in any irreversible injury (98.8% being the higher injury) under investigated conditions, thus a bacteria regrowth may take place under optimum environment conditions if any final disinfection process (e.g., chlorine or chlorine dioxide) is not used.

    Combined sewer overflows (CSOs) are a known source of human fecal pollution and human pathogens in urban water bodies, which may present a significant public health threat. To monitor human fecal contamination in water, bacterial fecal indicator organisms (FIOs) are traditionally used. However, because FIOs are not specific to human sources and do not correlate with human pathogens, alternative fecal indicators detected using qPCR are becoming of interest to policymakers. For this reason, this study measured correlations between the number and duration of CSOs and mm of rainfall, concentrations of traditional FIOs and alternative indicators, and the presence of human pathogens in two urban creeks. Samples were collected May–July 2016 and analyzed for concentrations of FIOs (total coliforms and E. coli) using membrane filtration as well as for three alternative fecal indicators (human Bacteroides HF183 marker, human polyomavirus (HPoV), pepper mild mottle virus (PMMoV)) and nine human pathogens using qPCR. Four of the nine pathogens analyzed were detected at these sites including adenovirus, Enterohemorrhagic E. coli, norovirus, and Salmonella. Among all indicators studied, human Bacteroides and total coliforms were significantly correlated with recent CSO and rainfall events, while E. coli, PMMoV, and HPoV did not show consistent significant correlations. Further, human Bacteroides were a more specific indicator, while total coliforms were a more sensitive indicator of CSO and rainfall events. Results may have implications for the use and interpretation of these indicators in future policy or monitoring programs.

    Full Text Available The greatest risk of drinking water supply is a failure to provide safe drinking water for communities. Based on IPA Kedunguling testing report on March 2016 noted that sample exceeding the quality standart of Peraturan Menteri Kesehatan RI No 492/2010 for the total coliform quality standart. The presence of total coliforms indicating water contamination by pathogen means the water is not safe to consume. The disinfection process has an importance rule in pathogen inactivation. Disinfectant performance is influenced by temperature, pH, turbidity, and the presence of organic materials. One way to control the quality of water produced by using a risk management approach Failure Modes and Effect Analysis (FMEA methods. The potential risks should be measured to determine causes of the problems and find the appropriate risk reduction. The risk assessment is using Risk Priority Number (RPN scale as a basis prioritization of remedial action on issues. Based on identification and risk analysis using FMEA known that the greatest risk of failure is the stipulation of chlorine dose and organic substances (category of high risk level; residual chlorine (category of moderate risk level; turbidity and pH (very low risk level category. Improvement proposal that can be done to reduce total coliforms presence in IPA Kedunguling is by increasing residual chlorine to 0.6 mg/l, set a daily chlorine level, controlling DBPs forming by lowering the concentration of organic precursor using granular activated carbon (GAC or aeration, by lowering the dose of disinfectant, set aside DBPs after the compound is formed using granular activated carbon (GAC, turbidity and pH monitoring, and regularly washing the filters

    The concentrations of nutrients (nitrogen and phosphorus), total metals, and fecal coliform (FC) coupling with chlorophyll- a (chl- a), 5-day biochemical oxygen demand (BOD5) and other general environmental parameters were evaluated at the sub-surface and near-bottom water columns of 13 stations in the Sibu Laut River during low and high slack waters. The results indicated that inorganic nitrogen (mainly nitrate) was the primary form of nitrogen whereas organic phosphorus was the major form of phosphorus. The abundance of total heavy metals in Sibu Laut River and its tributaries was in the order of Pb < Cu < Zn < Cd. Fecal coliform concentration was relatively low along Sibu Laut River. The shrimp farm effluents contributed a substantial amount of chl- a, BOD5, nutrients, and FC to the receiving creek except for total metals. Nevertheless, the influence was merely noticeable in the intake creek and amended rapidly along Selang Sibu River and brought minimal effects on the Sibu Laut River. Besides, the domestic sewage effluents from villages nearby also contributed a substantial amount of pollutants.

    Photocatalytic water treatment has a currently elevated electricity demand and maintenance costs, but the photocatalytic water treatment may also assist in overcoming the limitations and drawbacks of conventional water treatment processes. Among the Advanced Oxidation Processes, heterogeneous photocatalysis is one of the most widely and efficiently used processes to degrade and/or remove a wide range of polluting compounds. The goal of this work was to find out a highly efficient photocatalytic disinfection process in superficial water with different doped photocatalysts and using three sources of radiation: mercury vapor lamp, solar simulator and UV-A LED. Three doped photocatalysts were prepared, SiZnO, NSiZnO and FNSiZnO. The inactivation efficiency of each synthesized photocatalysts was compared to a TiO2 P25 (Degussa(®)) 0.5 g L(-1) control. Photolysis inactivation efficiency was 85% with UV-A LED, which is considered very high, demanding low electricity consumption in the process, whereas mercury vapor lamp and solar simulator yielded 19% and 13% inactivation efficiency, respectively. The best conditions were found with photocatalysts SiZnO, FNSiZnO and NSiZnO irradiated with UV-A LED, where efficiency exceeded 95% that matched inactivation of coliforms using the same irradiation and photocatalyst TiO2. All photocatalysts showed photocatalytic activity with all three radiation sources able to inactivate total coliforms from river water. The use of UV-A LED as the light source without photocatalyst is very promising, allowing the creation of cost-effective and highly efficient water treatment plants. Copyright © 2016 Elsevier Ltd.

    In recent times, surface water resource in the Western Region of Ghana has been found to be inadequate in supply and polluted by various anthropogenic activities. As a result of these problems, the demand for groundwater by the human populations in the peri-urban communities for domestic, municipal and irrigation purposes has increased without prior knowledge of its water quality. Water samples were collected from 14 public hand-dug wells during the rainy season in 2013 and investigated for total coliforms, Escherichia coli, mercury (Hg), arsenic (As), cadmium (Cd) and physicochemical parameters. Multivariate statistical analysis of the dataset and a linear stoichiometric plot of major ions were applied to group the water samples and to identify the main factors and sources of contamination. Hierarchal cluster analysis revealed four clusters from the hydrochemical variables (R-mode) and three clusters in the case of water samples (Q-mode) after z score standardization. Principal component analysis after a varimax rotation of the dataset indicated that the four factors extracted explained 93.3 % of the total variance, which highlighted salinity, toxic elements and hardness pollution as the dominant factors affecting groundwater quality. Cation exchange, mineral dissolution and silicate weathering influenced groundwater quality. The ranking order of major ions was Na(+) > Ca(2+) > K(+) > Mg(2+) and Cl(-) > SO4 (2-) > HCO3 (-). Based on piper plot and the hydrogeology of the study area, sodium chloride (86 %), sodium hydrogen carbonate and sodium carbonate (14 %) water types were identified. Although E. coli were absent in the water samples, 36 % of the wells contained total coliforms (Enterobacter species) which exceeded the WHO guidelines limit of zero colony-forming unit (CFU)/100 mL of drinking water. With the exception of Hg, the concentration of As and Cd in 79 and 43 % of the water samples exceeded the WHO guideline limits of 10 and 3

    Bacterial pathogens are a major cause of water quality impairment in the United States. Freshwater ecosystems provide the ecosystem service of reducing pathogen levels by diluting and removing pathogens as water flows from source areas through the river network. However, the integration of field-scale monitoring data and watershed-scale hydrologic models to estimate pathogen loads and removal in varied aquatic ecosystems is still limited. In this study we applied a biogeochemical river network model (the Framework for Aquatic Modeling in the Earth System or FrAMES) and utilized available field data the Oyster R. watershed, a small (51.7 km2) draining coastal New Hampshire (NH, USA), to quantify pathogen removal at the river network scale, using fecal coliform as an indicator. The Oyster R. Watershed is comprised of various land use types, and has had its water quality monitored for fecal coliform, dissolved oxygen, and turbidity since 2001. Water samples were also collected during storm events to account for storm responses. FrAMES was updated to incorporate the dominant processes controlling fecal coliform concentrations in aquatic ecosystems: spatially distributed terrestrial loading, in-stream removal, dilution, and downstream transport. We applied an empirical loading function to estimate the terrestrial loading of fecal coliform across flow conditions. Data was collected from various land use types across a range of hydrologic conditions. The loading relationship includes total daily precipitation, antecedent 24-hour rainfall, air temperature, and catchment impervious surface percentage. Attenuation is due to bacterial "die-off" and dilution processes. Results show that fecal coliform input loads varied among different land use types. At low flow, fecal coliform concentrations were similar among watersheds. However, at high flow the concentrations were significantly higher in urbanized watersheds than forested watersheds. The mainstem had lower fecal coliform

    The use of antibiotics as growth promoters in feed has been fully or partially banned in several countries. The objective of this study was to evaluate effects of levan-type fructan on growth performance, nutrient digestibility, faecal shedding of lactic acid bacteria and coliform bacteria, diarrhoea scores, and faecal gas emission in weaning pigs. A total of 144 weaning pigs [(Yorkshire × Landrace) × Duroc] were randomly allocated to four diets: corn-soybean meal-based diets supplemented with 0, 0.1, 0.5, or 1.0 g kg -1 levan-type fructan during this 42-day experiment. During days 0 to 21 and 0 to 42, average daily gain and average daily feed intake were linearly increased (P bacteria counts were linearly increased (P = 0.001). The results indicate that dietary supplementation with increasing levan-type fructan enhanced growth performance, improved nutrient digestibility, and increased faecal lactic acid bacteria counts in weaning pigs linearly. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Total coliforms and total coliforms resistant to streptomycin, tetracycline, or chloramphenicol were isolated from filtered activated sludge effluents before and after UV light irradiation. Although the UV irradiation effectively disinfected the wastewater effluent, the percentage of the total surviving coliform population resistant to tetracycline or chloramphenicol was significantly higher than the percentage of the total coliform population resistant to those antibiotics before UV irradiation. This finding was attributed to the mechanism of R-factor mediated resistance to tetracycline. No significant difference was noted for the percentage of the surviving total coliform population resistant to streptomycin before or after UV irradiation. Multiple drug resistant to patterns of 300 total coliform isolates revealed that 82% were resistant to two or more antibiotics. Furthermore, 46% of these isolates were capable of transferring antibiotic resistance to a sensitive strain of Escherichia coli

    Full Text Available ABSTRACT In this study, we evaluated the risk factors associated with the occurrence of total coliforms, thermotolerant coliforms, and intestinal parasite eggs in vegetables from an agroindustry in the city of Ibiúna - SP, Brazil. A questionnaire with 17 questions was applied to 24 producers to carry out a diagnosis of the risk factors and their posterior association or not with total coliforms, thermotolerant coliforms, and intestinal parasite eggs. The questions addressed mainly the production system, fertilizer used, source of the water used for irrigation, sanitization of the vegetables, and form of transport. For the investigation of total coliforms, thermotolerant coliforms, and intestinal parasite eggs, the samples were processed at the microbiology and parasitology laboratory of the Federal Institute of São Paulo, São Roque Campus. The results revealed that total coliforms were found in 100% of the investigated samples and thermotolerant coliforms were detected in 95.83% of the samples. There was a significant statistical association for the risk factor use of reservoir water, where there was release of wastewater and absence of sanitization of the vegetables at the moment of harvest in relation to the presence of thermotolerant coliforms. Intestinal parasite eggs were found in 33.33% of the samples.

    Full Text Available Segundo o IBGE (2000, 73% dos municípios brasileiros possuem menos de 20.000 habitantes, que em sua maior parte vive na zona rural ou em pequenos núcleos urbanos. Quase a totalidade dos esgotos destas cidades é lançada nos corpos hídricos, contribuindo com o agravamento dos problemas de saúde pública e ambiental. Esses danos podem ser minimizados com o emprego de sistemas de tratamento simples, eficientes, sustentáveis e economicamente viáveis. O filtro anaeróbio com recheio de bambu combinado com filtros de areia satisfaria estas exigências, propiciando um efluente adequado para disposição nos cursos d'água ou para reúso, resguardando as fontes de água potável. A aplicação piloto deste método demonstrou que no emprego de baixas cargas de efluente anaeróbio nos filtros de areia havia uma remoção superior a 96% da DBO, adequação na emissão de coliformes totais e uma completa nitrificação. Aumentando-se as cargas, ocorria uma pequena redução da eficiência, no entanto os resultados ainda eram satisfatórios.According to IBGE (2000 73% of the Brazilian cities are considered small communities with population smaller than 20,000 inhabitants. The majority of domestic wastewater of these places is normally disposed in rivers with no treatment. As a consequence, the irregular disposal may cause health and environmental problems. To reduce this risk it is necessary to develop treatment systems that are simple, efficient, sustainable and of low cost. The treatment of wastewater using up flow anaerobic filter combined with sand filters would be able to satisfy these exigencies, producing an effluent that could be disposed in rivers or even be reused, safeguarding the sources of potable water. The system achieved BOD removal of 96% and complete nitrification for the application of low loads. The increase of the applied loads caused a reduction in the efficiency; however the final values were still satisfactory.

    The need to separate bacteria from sediment in order to appropriately count them has led to test the efficacy of different techniques. In this research, traditional techniques such as manual shaking, homogenization, ultrasonication, and surfactant are compared. Moreover, the possibility of using a set of enzymes (pancreatine) and an antibiotic (ampicillin) for sediment coliform extraction is proposed. Samples were obtained from Xochimilco Lake in Mexico City. The most probable number of coliform bacteria was determined after applying the appropriate separation procedure. Most of the techniques tested led to numbers similar to those of the control (manual shaking). Only with the use of ampicillin, a greater total coliform concentration was observed (Mann-Whitney, z = 2.09; p = 0.03). It is possible to propose the use of ampicillin as a technique for total coliform extraction; however, it is necessary to consider sensitivity of bacteria to the antibiotic.

    Full Text Available Individuals of the water louse, Asellus aquaticus, enter drinking water distribution systems in temperate parts of the world, where they establish breeding populations. We analysed populations of surface water A. aquaticus from two ponds for associated faecal indicator bacteria and assessed the risk of A. aquaticus transporting bacteria into distribution systems. Concentrations of up to two E. coli and five total coliforms·mL−1 were measured in the water and 200 E. coli and >240 total coliforms·mL−1 in the sediments of the investigated ponds. Concentrations of A. aquaticus associated bacteria never exceeded three E. coli and six total coliforms·A. aquaticus−1. During exposure to high concentrations of coliforms, concentrations reached 350 coliforms·A. aquaticus−1. A. aquaticus associated E. coli were only detected as long as E. coli were present in the water and sediment. The calculated probability of exceeding drinking water guideline values in non-disinfected systems by intrusion of A. aquaticus was low. Only in scenarios with narrow pipes and low flows, did total coliforms exceed guideline values, implying that the probability of detection by routine monitoring is also low. The study expands the knowledge base for evaluating incidents with presence of coliform indicators in drinking water by showing that intruding A. aquaticus were not important carriers of E. coli or other coliform bacteria even when emerging from faecally contaminated waters.

Materiales y métodos: Se estudiaron 45 muestras de pollo crudo (15 correspondieron a pollo sin aliños, 15 con aliños y 15 de origen industrial. Los indicadores de calidad sanitaria evaluados fueron: bacterias aerobias mesófilas, coliformes totales, Escherichia coli y Staphylococcus aureus, utilizando la metodología de la Comisión Venezolana de Normas Industriales. La identificación microbiológica y serológica de Salmonella spp. se realizó mediante técnicas convencionales. La sensibilidad antimicrobiana se determinó por concentración inhibitoria mínima (CIM y, para la detección de β-lactamasas de espectro expandido (BLEE, se utilizó la prueba del sinergismo del doble disco. La sensibilidad a desinfectantes se determinó por el método de dilución-neutralización. Resultados: Independientemente de las características de la muestra de pollo crudo (no industrial y del establecimiento comercial, los indicadores: bacterias aerobias mesófilas, coliforme totales, E. coli y S. aureus, superaron significativamente los recuentos límites de aceptabilidad. Salmonella enterica se aisló en 20% de las muestras, y las serovariedades Heidelberg (55,6% y Enteritidis (22,2% fueron las más frecuentes. Estas variedades serológicas presentaron multirresistencia y producción de BLEE, pero fueron sensibles a los desinfectantes probados. Conclusión: Los pollos crudos con aliños y sin ellos, manufacturados en los establecimientos estudiados, no cumplen con la calidad microbiológica adecuada, lo que hace de ellos un producto perecedero a corto plazo y un nicho favorecedor de patógenos importantes que amenazan la salud de los consumidores.Objectives: Evaluate the sanitary quality of raw chicken sold in the urban area of the State of Merida

    The current definition of coliform bacteria is method-dependent, and when different culture-based methods are used, discrepancies in results can occur and affect the accuracy in identifying true coliforms. This study used an alternative approach to identify true coliforms by combing the phenotypic traits of the coliform isolates and the phylogenetic affiliation of 16S rRNA gene sequences together with the use of lacZ and uidA genes. A collection of 1404 isolates from 12 US Environmental Protection Agency approved coliform-testing methods were characterized based on their phylogenetic affiliations and responses to their original isolation medium and Lauryl Tryptose broth, m-Endo and MI agar media. Isolates were phylogenetically classified into 32 true coliform or targeted Enterobacteriaceae (TE) groups, and 14 non-coliform or non-targeted Enterbacteriaceae (NTE) groups. It was statistically shown that detecting true-positive (TP) events is more challenging than detecting true-negative (TN) events. Furthermore, most false-negative (FN) events were associated with four TE groups (i.e., Serratia group I, Providencia, Proteus, and Morganella), and most false-positive (FP) events with two NTE groups, Aeromonas and Plesiomonas. In Escherichia coli testing, 18 out of 145 E. coli isolates identified by those enzymatic methods were validated as FNs. The reasons behind the FP and FN reactions could be explained through the analysis of the lacZ and uidA gene. Overall, combining the analyses of 16S rRNA, lacZ and uidA genes with the growth responses of TE and NTE on culture-based media is an effective way to evaluate the performance of coliform detection methods.

Isolates were phylogenetically classified into 32 true coliform or targeted Enterobacteriaceae (TE) groups, and 14 non-coliform or non-targeted Enterbacteriaceae (NTE) groups. It was statistically shown that detecting true-positive (TP) events is more challenging than detecting true-negative (TN) events. Furthermore, most false-negative (FN) events were associated with four TE groups (i.e., Serratia group I, Providencia, Proteus, and Morganella), and most false-positive (FP) events with two NTE groups, Aeromonas and Plesiomonas. In Escherichia coli testing, 18 out of 145 E. coli isolates identified by those enzymatic methods were validated as FNs. The reasons behind the FP and FN reactions could be explained through the analysis of the lacZ and uidA gene. Overall, combining the analyses of 16S rRNA, lacZ and uidA genes with the growth responses of TE and NTE on culture-based media is an effective way to evaluate the performance of coliform detection methods.

    Total arsenic concentrations (t As) and the presence of total and fecal coliforms in drinking water from Tecuala, Nayarit, Mexico, were determined. The presence of t As was analyzed by means of hydride generation atomic fluorescence spectrometry. Total and fecal coliforms were determined through the Most Probable Number (MPN) method. According to the results, the mean concentration of t As in Tecuala wa 15.82 {mu}g/L, in Atotonilco 19.88 {mu}g/L, in Pajaritos 21.49 {mu}g/L, in Quimichis 17.80 {mu}g/L, and in Playas de Novillero 19.79 {mu}g/L. The t As concentrations in drinking water from Tecuala, Nayarit, are within the limit set by the Mexican official standards (25 {mu}g/L); still, they are over the limit established by the World Health Organization (10 {mu}g/L). The concentration of coliforms in water from wells 1 and 3 was 180 MPN/100 ml and 43 MPN/100 ml for well water 2. The presence of total and fecal coliforms, suggest the infiltration of sewage which could increase the levels of dissolved arsenic. The results of this study will serve as an antecedent of the water quality in Tecuala, Nayarit. (Author)

    ABSTRACT: This study had the purpose to observe the effect of thawing procedures on survival of coliform and mesophilic aerobic bacteria in hospital-made enteral feedings. The samples are represented by three different lots. The tests were realized in three moments: immediately after the sample preparation and after freezing during 1 or 2 months. The thawing procedures were denominated convencional and alternative. The first, used by hospital, utilizes water bath at 50ºC, considering the time spent from the total thawing to its distribution in the infirmaries. The second was the fast thawing made by microwaving. The results showed that the reduction of the mesophiles and coliform was related to the time the samples were frozen. The results obtained indicate an advantage of the alternative method, which presented lower total and fecal coliform counts than the conventional one. KEYWORDS: Enteral feedings; thawing; food microbiology.

    The presence of coliform bacteria in pasteurized fluid milk typically indicates that product contamination occurred downstream of the pasteurizer, but it may also indicate pasteurization failure. Although coliform detection is frequently used as a hygiene indicator for dairy products, our understanding of the taxonomic and phenotypic coliform diversity associated with dairy products is surprisingly limited. Therefore, using Petrifilm Coliform Count plates (3M, St. Paul, MN), we isolated coliforms from high-temperature, short-time (HTST)-pasteurized fluid milk samples from 21 fluid milk processing plants in the northeast United States. Based on source information and initial characterization using partial 16S rDNA sequencing, 240 nonredundant isolates were obtained. The majority of these isolates were identified as belonging to the genera Enterobacter (42% of isolates), Hafnia (13%), Citrobacter (12%), Serratia (10%), and Raoultella (9%); additional isolates were classified into the genera Buttiauxella, Cedecea, Kluyvera, Leclercia, Pantoea, and Rahnella. A subset of 104 representative isolates was subsequently characterized phenotypically. Cold growth analysis in skim milk broth showed that all isolates displayed at least a 2-log increase over 10 d at 6°C; the majority of isolates (n=74) displayed more than a 5-log increase. In total, 43% of the representative isolates displayed lipolysis when incubated on spirit blue agar at 6°C for 14 d, whereas 71% of isolates displayed proteolysis when incubated on skim milk agar at 6°C for 14 d. Our data indicate that a considerable diversity of coliforms is found in HTST-pasteurized fluid milk and that a considerable proportion of these coliforms have phenotypic characteristics that will allow them to cause fluid milk spoilage.

    Fecal bacterial contamination of nearshore waters has direct economic impacts to coastal communities through the loss of shellfisheries and restrictions of recreational uses. We conducted seasonal measurements of fecal coliform (FC) sources and transport pathways contributing to FC contamination of Buttermilk Bay, a shallow embayment adjacent to Buzzards Bay, MA. Typical of most coastal embayments, there were no direct sewage discharges (i.e., outfalls), and fecal bacteria from human, domestic animal, and wildlife pools entered open waters primarily through direct deposition or after transport through surface waters or groundwaters. Direct fecal coliform inputs to bay waters occurred primarily in winter (December-March) from waterfowl, ~33 x 1012 FC yr-1 or ~67% of the total annual loading. Effects of waterfowl inputs on bay FC densities were mitigated by their seasonality, wide distribution across the bay surface, and the apparent limited dispersal from fecal pellets. On-site disposal of sewage by septic systems was the single largest FC source in the watershed-embayment system, 460 x 1012 FC yr-1, but due to attenuation during subsurface transport only a minute fraction, rain events with discharge concentrated in nearshore zones, wet-weather flows were found to have a disproportionately high impact on nearshore FC levels. Elution of FC from shoreline deposits of decaying vegetation (wrack) comprised an additional coliform source. Both laboratory and field experiments suggest significant elution of bacteria from wrack, ~3 x 1012 FC yr-1 on a bay-wide basis (6% of annual input), primarily by periodic tidal flooding and possibly by major rain events. Release of coliforms during resuspension of subtidal sediments was estimated to be a minor source in this system (<1.5 x 1012 FC yr-1 or < 3% of annual input), primarily associated with large storm events in the fall and winter. Based upon the relative source strengths and the spatial and temporal patterns of FC input

    The effect of six water quality constituents on wastewater effluent disinfection by tin oxide anodes (TOAs) was investigated in single cell laboratory reactors. Several concentrations of suspended solids, chemical oxygen demand (COD), alkalinity, ammonia-nitrogen, nitrite-nitrogen, and nitrate-nitrogen were added to media containing 10 6 total coliform bacteria mL -1 . Current was applied through the TOAs, and coliform bacteria viability was analyzed over time. Over 99.9% inactivation of coliform bacteria was found over 15 min in TOA reactors. Concentrations of the six water quality constituents typical of concentrations found in wastewaters had no effect on TOA disinfection efficacy. The results of this research demonstrate that TOAs, which could potentially be powered by solar panels, have potential as a sustainable disinfection process compared to chlorine, ozone, and ultraviolet light.

  2. Patterns and sources of fecal coliform bacteria in three streams in Virginia, 1999-2000

    Surface-water impairment by fecal coliform bacteria is a water-quality issue of national scope and importance. In Virginia, more than 175 stream segments are on the Commonwealth's 1998 303(d) list of impaired waters because of elevated concentrations of fecal coliform bacteria. These fecal coliform-impaired stream segments require the development of total maximum daily load (TMDL) and associated implementation plans, but accurate information on the sources contributing these bacteria usually is lacking. The development of defendable fecal coliform TMDLs and management plans can benefit from reliable information on the bacteria sources that are responsible for the impairment. Bacterial source tracking (BST) recently has emerged as a powerful tool for identifying the sources of fecal coliform bacteria that impair surface waters. In a demonstration of BST technology, three watersheds on Virginia's 1998 303(d) list with diverse land-use practices (and potentially diverse bacteria sources) were studied. Accotink Creek is dominated by urban land uses, Christians Creek by agricultural land uses, and Blacks Run is affected by both urban and agricultural land uses. During the 20-month field study (March 1999?October 2000), water samples were collected from each stream during a range of flow conditions and seasons. For each sample, specific conductance, dissolved oxygen concentration, pH, turbidity, flow, and water temperature were measured. Fecal coliform concentrations of each water sample were determined using the membrane filtration technique. Next, Escherichia coli (E. coli) were isolated from the fecal coliform bacteria and their sources were identified using ribotyping (a method of 'genetic fingerprinting'). Study results provide enhanced understanding of the concentrations and sources of fecal coliform bacteria in these three watersheds. Continuum sampling (sampling along the length of the streams) indicated that elevated concentrations of fecal coliform bacteria

    Peri-urban vegetable farming in Ghana is an important livelihood activity for an increasing number of people. However, increasing quality and public health concerns have been raised, partly because freshwater availability for irrigation purposes is a major constraint. This paper investigated on-farm vegetable contamination and potential health risks using samples of lettuce, spring onions and cabbage randomly selected from 18 vegetable farms in peri-urban Kumasi, Ghana. Vegetable samples were tested for total coliform, fecal coliform, Escherichia coli and Salmonella spp. bacteria contamination using the Most Probable Number method. Results show high contamination levels of total and fecal coliforms, and Escherichia coli bacteria in all 18 vegetable samples. The mean total coliform/100 ml concentration for spring onions, lettuce and cabbage were 9.15 × 10(9), 4.7 × 10(7) and 8.3 × 10(7) respectively. The mean fecal coliform concentration for spring onions, lettuce and cabbage were also 1.5 × 10(8), 4.15 × 10(7) and 2.15 × 10(7) respectively, while the mean Escherichia coli bacteria contamination for spring onions, lettuce and cabbage were 1.4 × 10(8), 2.2 × 10(7) and 3.2 × 10(7) respectively. The level of total coliform, fecal coliform and Escherichia coli bacteria contamination in all the vegetable samples however declined as the distance between the main water source (Wiwi River) and farms increases. Nonetheless, all contamination levels were well above acceptable standards, and could therefore pose serious public health risks to consumers. Increased education and supervision of farmers, as well as public health and food hygiene education of consumers, are critical to reducing on-farm vegetable contamination and the health risks associated with consumption of such vegetables.

    Widespread fecal pollution of surface water may present a major health risk and a significant pathway for dissemination of antibiotic resistance bacteria. The River Rhine is one of the longest and most important rivers in Europe and an important raw water source for drinking water production. A total of 100 coliform isolates obtained from River Rhine (Germany) were examined for their susceptibility to seven antimicrobial agents. Resistances against amoxicillin, trimethoprim/sulfamethoxazole and tetracycline were detected in 48%, 11% and 9% of isolates respectively. The antibiotic resistance could be traced back to the resistance genes bla TEM , bla SHV , ampC, sul1, sul2, dfrA1, tet(A) and tet(B). Whereby, the ampC gene represents a special case, because its presence is not inevitably linked to a phenotypic antibiotic resistance. Multiple antibiotics resistance was often accompanied by the occurrence of class 1 or 2 integrons. E. coli isolates belonging to phylogenetic groups A and B1 (commensal) were more predominant (57%) compared to B2 and D groups (43%) which are known to carry virulent genes. Additionally, six E. coli virulence genes were also detected. However, the prevalence of virulence genes in the E. coli isolates was low (not exceeding 4.3% per gene) and no diarrheagenic E. coli pathotypes were detected. This study demonstrates that surface water is an important reservoir of ARGs for a number of antibiotic classes such as sulfonamide, trimethoprim, beta-lactam-antibiotics and tetracycline. The occurrence of antibiotic resistance in coliform bacteria isolated from River Rhine provides evidence for the need to develop management strategies to limit the spread of antibiotic resistant bacteria in aquatic environment.

    Full Text Available Background: The poor sanitation and small numbers of households who own toilet in Sekotong regency may relate to the diarrheal events due to the fecal coliform contamination in drinking water. Aim: This paper aims to provide the concentrations of fecal coliform bacteria in shallow well waters and the factors associated to its growth. Method: Fifteen groundwater samples were collected from 5 shallow wells to provide the concentrations of total fecal coliform bacteria (FC, mercury concentration, inorganic nitrogen compounds (represent as ammonia, nitrate, and nitrite, total phosphorus (TP, dissolved oxygen (D, pH, and salinity. The concentration of the parameters was then compared to the safe limit set by World Health Organization (WHO. Results: The results indicated that the drinking water resources at the Sekotong regency were contaminated by coliform and mercury. One location with low mercury concentration was recorded with E. coli contamination. Residence, agriculture, and animal livestock were subjected as the sources of coliform contamination. Mercury concentrations may inverse the growth of FC. No apparent relationship was found between total phosphorous and inorganic nitrogen compounds to FC growth. However, we recognized the FC growth responded positively to the level of phosphorous in waters, but associated negatively to nitrate concentration. An inverse correlation was also found between coliform survival and salinity in this study. The pH range at 6.05 – 6.50 supported FC survival. Conclusion: The drinking water resources at the Sekotong shallow wells were contaminated by coliform and mercury. It is important for local government to inform drinking water protection and treatment.

    Full Text Available La Ciénaga Grande de Santa Marta es el sistema lagunar costero más grande e importante de Colombia y el más extenso del Caribe. En su territorio se alojan siete poblaciones carentes de un sistema de saneamiento básico adecuado, que vierten sus desechos sin ningún tipo de tratamiento directamente a la ciénaga. Teniendo en cuenta la importancia ambiental de este cuerpo de agua y con el objeto de conocer su calidad sanitaria se determinaron las concentraciones de Coliformes termotolerantes en aguas adyacentes de dos poblaciones costeras (Tasajera e isla del Rosario y tres palafiticas (Buenavista, Nueva Venecia y Trojas de Cataca durante el periodo 2004-2007. Adicionalmente, se realizaron mediciones de pH, temperatura, salinidad y oxígeno disuelto en cada sitio de muestreo. Las mayores concentraciones de Coliformes se encontraron en el palafito Trojas de Cataca, en la época seca mayor de cada año (7.800-9.000 NMP/ 100 mL y los menores niveles en la estación Buenavista (2-1.100 NMP/100mL. El patrón de comportamiento de las densidades de Coliformes en las poblaciones costeras fue similar en el tiempo y no se observó ninguna relación directa entre las variables fisicoquímicas y el grupo Coliformes. Dado lo observado, se considera importante vigilar la calidad del agua en el estuario, teniendo en cuenta que constituye una fuente potencial de riesgo para el desarrollo de las actividades económicas de la zona y para la salud de los pobladores.

    Full Text Available En este breve trabajo se pretende traer a la memoria el recuerdo de las «Conferencias Sanitarias Internacionales» que, en intervalos casi regulares, se celebraron desde 1851 hasta 1938, consistiendo en una serie de reuniones en las que participaron los más importantes sanitarios, higienistas y científicos de cada época, así como los embajadores correspondientes de los más importantes países, intentando unos acuerdos que fuesen conformes para todas las naciones y que evitasen la llegada y extensión de las enfermedades pestilenciales. Esta labor resultaba harto difícil en aquellos tiempos, dado que los participantes se encontraban divididos en dos grandes y potentes grupos: los contagionistas (partidarios de los cordones sanitarios, cuarentenas y lazaretos y los miasmáticos o anticontagionistas (que rechazaban estas medidas y defendían el pleno saneamiento: individual, ambiental y general. Los descubrimientos bacteriológicos que por entonces se fueron produciendo, facilitaron los caminos para un mejor entendimiento entre los participantes en las Conferencias. En este breve trabajo se ofrece un mínimo resumen del contenido de cada una de las mismas. Hay que destacar que estas Conferencias fueron el origen de la Organización Mundial de la Salud. Se mencionan algunas de las dificultades encontradas para conseguir las fotocopias de los textos de las 14 Actas de las Conferencias.

    Lago de Colina (Colina Lake) is located about 180 km south of the city of Chihuahua (Mexico), and during the Semana Santa (Holy Week) vacation period its recreational use is high. The objective of this study was to quantify coliform and heavy metal levels in this water body before and after the Holy Week vacation period in 2010. Twenty sampling points were randomly selected and two water samples were collected at each point near the surface (0.30 m) and at 1 m depth. After the Holy Week vacation the same twenty points were sampled at the same depths. Therefore, a total 80 water samples were analyzed for fecal and total coliforms and levels of the following metals: Al, As, B, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Se, Si and Zn. It was hypothesized that domestic tourism contaminated this water body, and as a consequence, could have a negative impact on visitor health. An analysis of variance (ANOVA) study was performed for each element and its interactions considering a factorial design where factor A was sample date and factor B was sample depth. Fecal coliforms were only detected at eight sampling points in the first week, but after Holy Week, both fecal and total coliforms were detected at most sampling points. The concentrations of Al, B, Na, Ni and Se were only statistically different for factor A. The levels of Cr, Cu, K and Mg was different for both date and depth, but the dual factor interaction was not significant. The amount of Ca and Zn was statistically different due to date, depth and their interaction. No significant differences were found for any factor or the interaction for the elements As, Fe and Mn. Because of the consistent results, it is concluded that local tourism is contaminating the recreational area of Colina Lake, Chihuahua, Mexico. PMID:21776236

    Yeasts and coliform bacteria were isolated from water that accumulated in the central cups and adjacent leaf axilae of two bromeliads, Neoregelia cruenta of a coastal sand dune and Quesnelia quesneliana of a mangrove ecosystem near the city of Rio de Janeiro, Brazil. The mean total coliform counts were above 10,000 per 100 mL for waters of both plants, but the mean fecal coliform counts were only 74 per 100 mL for Q. quesneliana and mostly undetected in water from N. cruenta. Of 90 fecal coliform isolates, 51 were typical of Escherichia coli in colony morphology and indol, methyl red, Volges-Proskauer, and citrate (IMViC) tests. Seven representatives of the typical E. coli cultures were identified as this species, but the identifications of nine other coliform bacteria were mostly dubious. The yeast community of N. cruenta was typical of plant surfaces with basidiomycetous yeasts anamorphs, and the black yeast Aureobasidium pullulans was prevalent. Quesnelia quesneliana had a substantial proportion of ascomycetous yeasts and their anamorphs, including a probable new biotype of Saccharomyces unisporus. Our results suggested that the microbial communities in bromeliad waters are typically autochtonous and not contaminants.

    Full Text Available Background and aims. Burning mouth syndrome (BMS is a chronic pain disorder characterized by a chief complaint of oral burning/pain with no clinically observable oral mucosal lesions. The prevalence of BMS has been reported to be 2.5- 5.1% in the general population and several psychological disorders have been reported as associated or predisposing factors for BMS. The aim of this study was to determine the correlation between BMS and anxiety in the elderly residents of sanitaria in Tehran, Iran. Materials and methods. In a cross-sectional analytical study, 50 patients with BMS were included along with 50 healthy individuals as controls. Inclusion criteria were: age over 60 years, burning sensation in the mouth, normal oral mucosa, absence of diabetes, satisfactory prosthesis, absence of iron deficiency and other nutrients, and no heavy smoking habits. Similar inclusion criteria were considered for the control group without any oral complaints. Burning/pain severity was assessed by a 100-mm visual analog scale and the severity of anxiety (state, trait, and total was determined by Cattell's Anxiety Scale. Data was analyzed by t-test and Pearson's correlation coefficient. Results. Individuals with BMS assessed their burning/pain severity to be 27.4 mm (95% CI=25.2 - 29.6 mm. Standardized total anxiety scale in individuals with and without BMS (±SE for mean was 5.9±0.2 and 4.6±0.3 with significant differences (p=0.001. Similar significant differences were observed in state and trait anxiety between the two groups. Conclusion. It seems that both state and trait anxiety are associated with burning mouth syndrome.

    A survey of the occurrence of enteric indicator organisms (e. g. total and fecal coliform) and enteric pathogenic bacteria (Salmonella sp.) was undertaken at ten sites, along the northern coast of the Gulf of Aq aba (Jordan)m during the period October 1994 to September 1995. Both total coliforms and Escherichia coli counts were within the accepted international standards for marine bathing water. the mean value per 100 ml seawater ranged between 18 to 70(n=12 months) for total coliforms, 1 to 27 (n=8 mon thus) for Escherichia coli and 1 to 9 (n = 8 months) for Salmonella species. The analysis of va rance for total coliforms revealed a highly significant temporal variations (P<0.001), but no significant spatial differences were found .Whereas, Salmonella sp. counts showed significant spatial variations (P<0.001), with the Border site being significantly different from the other sites except the Palace site. These results suggest that the hygienic water quality at the Jordanian side of the Gulf of Aq aba, is good all over the year although the sewage discharge from Ei lat might cause a health hazard as to be the major source of enteric pathogenic bacteria.

    Public aquaria evaluate coliform indicator bacteria levels in fish systems, but the purpose of testing, testing methods, and management responses are not standardized, unlike with the coliform bacteria testing for marine mammal enclosures required by the U.S. Department of Agriculture. An online survey was sent to selected aquaria to document current testing and management practices in fish systems without marine mammals. The information collected included indicator bacteria species, the size and type of systems monitored, the primary purpose of testing, sampling frequency, test methods, the criteria for interpreting results, corrective actions, and management changes to limit human exposure. Of the 25 institutions to which surveys were sent, 19 (76%) responded. Fourteen reported testing for fecal indicator bacteria in fish systems. The most commonly tested indicator species were total (86%) and fecal (79%) coliform bacteria, which were detected by means of the membrane filtration method (64%). Multiple types and sizes of systems were tested, and the guidelines for testing and corrective actions were highly variable. Only three institutions performed additional tests to confirm the identification of indicator organisms. The results from this study can be used to compare bacterial monitoring practices and protocols in fish systems, as an aid to discussions relating to the accuracy and reliability of test results, and to help implement appropriate management responses.

    Full Text Available This study aimed at evaluating the bacteriological effects of the treatment of sheep meat contaminated with total coliforms, coliforms at 45 °C and Salmonella spp. by using irradiation at doses of 3 kGy and 5 kGy. Thirty sheep meat samples were collected from animals located in Rio de Janeiro State, Brazil, and then grouped in three lots including 10 samples: non-irradiated (control; irradiated with 3 kGy; and irradiated with 5 kGy. Exposure to gamma radiation in a 137Cs source-driven irradiating facility was perfomed at the Nuclear Defense Section of the Brazilian Army Technological Center (CTEx in Rio de Janeiro. The samples were kept under freezing temperature (-18 °C until the analyses, which occurred in two and four months after irradiation. The results were interpreted by comparison with the standards of the current legislation and demonstrated that non-irradiated samples were outside the parameters established by law for all groups of bacteria studied. Gamma irradiation was effective in inactivating those microorganisms at both doses tested and the optimal dose was achieved at 3 kGy. The results have shown not only the need for sanitary conditions improvements in slaughter and processing of sheep meat but also the irradiation effectiveness to eliminate coliform bacteria and Salmonella spp.

    Full Text Available Introducción: A pesar del creciente reconocimiento de la potencial utilidad de los estudios de coste-efectividad, en España no existe ningún criterio que permita establecer si una determinada tecnología sanitaria puede considerarse rentable o no. El objetivo de este trabajo es describir cuáles han sido los límites y criterios utilizados en España para recomendar la adopción o el rechazo de intervenciones sanitarias en función de su coste-efectividad. Método: Se realizó una revisión de las evaluaciones económicas de intervenciones sanitarias publicadas en España desde 1990 hasta 2001. Se seleccionaron las evaluaciones económicas completas en las que el cociente coste-efectividad se había expresado como coste por año de vida ganado (AVG, como coste por año de vida ajustado por calidad (AVAC o como coste por vida salvada. Se analizaron las intervenciones sobre las que los autores establecieron algún tipo de recomendación (de adopción o rechazo, así como los criterios utilizados. Resultados: Veinte (20% de las 100 evaluaciones económicas completas publicadas cumplieron con los criterios señalados. En 16 de los estudios, los resultados se expresaron como coste por AVG, en 6 como coste por AVAC y en 1 como coste por vida salvada. Se evaluaron un total de 82 intervenciones sanitarias, en 44 de las cuales se realizó algún tipo de recomendación. Los autores recomendaron la adopción de todas las intervenciones sanitarias con un coste-efectividad inferior a 30.000 euros (5 millones de pesetas por AVG. Por encima de esa cifra no se apreció ninguna tendencia. Conclusiones: Si bien los resultados deben ser interpretados con mucha precaución, dadas las limitaciones del estudio, los límites de coste-efectividad presentados en este trabajo podrían constituir una primera referencia a lo que podría considerarse como una intervención sanitaria eficiente en España.Introduction: Despite the growing recognition of the potential

    A survey of environmental surfaces in two Atlanta area day care centers was conducted to determine the prevalence of fecal coliform bacteria, considered a marker for the presence of fecal contamination which might contain pathogenic parasites, bacteria, or viruses. Fecal coliforms were found in 17 (4.3%) of 398 representative samples of building surfaces, furniture, and other objects. These surfaces may be involved in the chain of transmission of enteric diseases among children. Therefore, disinfection of inanimate objects, in addition to good handwashing, may be important in controlling the spread of enteric diseases in day care centers. PMID:6830225

    In many areas of Uruguay groundwater is the only source of water for human consumption and for industrial-agricultural economic activities. Traditionally considered as a safe source, groundwater is commonly used without any treatment. The Uruguayan law requires bacteriological (fecal) analysis for most water uses, but virological analyses are not mentioned in the legislation. In the Salto district, where groundwater is used for human consumption and for agricultural activities, bacterial contamination has been detected in several wells but no viruses analysis have been performed. The Republic University (UDELAR), with the support of the National Agency for Research and Innovation (ANII), is studying the incidence of virus and fecal bacteria in groundwater on an intensive agriculture area of the Salto district. An initial screening campaign of 44 wells was performed in which, besides total and fecal coliforms, rotavirus and adenovirus were detected. A subgroup of the screening wells (15) where selected for bimonthly sampling during a year. In accordance with literature results, single well data analysis shows that coliform and viral contamination can be considered as independent variables. However, when spatial data is integrated, coliform and viral contamination show linear correlation. In this work we present the survey results, we analyse the temporal incidence of variables like precipitation, temperature and chemical composition in well contamination and we discuss the value of coliforms as global indicator of viral contamination for the Salto aquifer.

    Despite the widespread use of coliforms as indicator bacteria, increasing evidence suggests that the Enterobacteriaceae (EB) and total gram-negative groups more accurately reflect the hygienic status of high-temperature, short-time pasteurized milk and processing environments. If introduced into milk as postpasteurization contamination, these bacteria may grow to high levels and produce a wide range of sensory-related defects. However, limited information is available on the use and survival of bacterial hygiene indicators in dairy products outside of pasteurized fluid milk and cheese. The goal of this study was to (1) provide information on the survival of a diverse set of bacterial hygiene indicators in the low pH environment of Greek yogurt, (2) compare traditional and alternative detection methods for their ability to detect bacterial hygiene indicators in Greek yogurt, and (3) offer insight into optimal hygiene indicator groups for use in low-pH fermented dairy products. To this end, we screened 64 bacterial isolates, representing 24 dairy-relevant genera, for survival and detection in Greek yogurt using 5 testing methods. Before testing, isolates were inoculated into plain, 0% fat Greek yogurt (pH 4.35 to 4.65), followed by a 12-h hold period at 4 ± 1°C. Yogurts were subsequently tested using Coliform Petrifilm (3M, St. Paul, MN) to detect coliforms; Enterobacteriaceae Petrifilm (3M), violet red bile glucose agar and the D-Count (bioMérieux, Marcy-l'Étoile, France) to detect EB; and crystal violet tetrazolium agar (CVTA) to detect total gram-negative bacteria. Overall, the non-EB gram-negative isolates showed significantly larger log reductions 12 h after inoculation into Greek yogurt (based on bacterial numbers recovered on CVTA) compared with the coliform and noncoliform EB isolates tested. The methods evaluated varied in their ability to detect different microbial hygiene indicators in Greek yogurt. Crystal violet tetrazolium agar detected the highest

    Full Text Available The indiscriminate launching in water bodies of domestic sewage without treatment, or even treated, but without appropriate disinfection, contributes with significant amount of organisms of the called "coliform group” that can carry specific illnesses agents propagated through the water. The application of effluent in the ground, instead of direct disposal in water courses, in addition to being an alternative way for the disposal of residues and biological control of pollutants, constitutes an adequate way of nutrients supply to the soil and plants. So, this work had as objective the evaluation of the reduction of fecal coliforms, after controlled applications of 60 days treated effluent in cultivated soil, by analyzing the increase of fluorescent rhizobacterias Pseudomonas fluorescens and Bacillus spp. present in the rhizospheres of different crops. The experiment was developed in field conditions in the Experimental Farm of Department of Agrarian Sciences of the University of Taubaté, municipality of Taubaté, SP. The Experimental design consisted of random blocks, with five treatments including annual crops (Oats, Barley, Triticale - a cross between wheat and rye, Black Beans and non-cultivated soil as witness - blank reference and four repetitions, totalizing 20 ground plots with area of 2 m x 1 m with 50 cm space among plots on a Dystrophic Red-Yellow Latossol. Results from the microbial analyses of rhizosphere and non-rhizosphere soil indicated that the rhizosphere of oats had denser rhizobacterias than the other crops. However, the greatest efficiency was found in the reduction of thermo-tolerant coliforms for both black beans and non-cultivated soil.

    The dry-composting toilet, which uses neither water nor sewage infrastructure, is a practical solution in areas with inadequate sewage disposal and where water is limited. These systems are becoming increasingly popular and are promoted to sanitize human excreta and to recycle them into fertilizer for nonedible plants, yet there are few data on the safety of this technology. This study analyzed fecal coliform reduction in approximately 90 prefabricated, dry-composting toilets (Sistema Integral de Reciclamiento de Desechos Orgánicos [SIRDOs]) that were installed on the U.S.-Mexico border in Ciudad Juárez, Chihuahua, Mexico. The purpose of this study was to determine fecal coliform reduction over time and the most probable method of this reduction. Biosolid waste samples were collected and analyzed at approximately 3 and 6 months and were classified based on U.S. Environmental Protection Agency standards. Results showed that class A compost (high grade) was present in only 35.8% of SIRDOs after 6 months. The primary mechanism for fecal coliform reduction was found to be desiccation rather than biodegradation. There was a significant correlation (P = 0.008) between classification rating and percent moisture categories of the biosolid samples: drier samples had a greater proportion of class A samples. Solar exposure was critical for maximal class A biosolid end products (P = 0.001). This study only addressed fecal coliforms as an indicator organism, and further research is necessary to determine the safety of composting toilets with respect to other pathogenic microorganisms, some of which are more resistant to desiccation.

    The relationship of fecal coliforms, Escherichia coli, and Salmonella spp. was examined in freshly harvested and stored shellfish. In 16 of 40 freshly collected oyster samples, fecal coliform levels were above the recommended wholesale level suggested by the National Shellfish Sanitation Program (less than or equal to 230/100 g), and Salmonella spp. were present in three of these samples. Salmonella spp. were not, however, present in any sample containing less than 230 fecal coliforms per 100 g. Analysis of the data suggests that low fecal coliform levels in both fresh and stored oysters are good indicators of the absence of Salmonella spp., but that high levels of fecal coliforms are somewhat limited in predicting the presence of Salmonella spp. E. coli levels correlated very strongly with fecal coliform levels in both fresh and stored oysters and clams, suggesting that there is no advantage in replacing fecal coliforms with E. coli as an indicator of shellfish quality.

    The present study evaluated the performance of the species Mentha aquatica in constructed wetlands of horizontal subsurface flow (CW-HSSF) with regard to the removal of coliforms bacteria in an effluent from the primary treatment of sewage as well as to obtain adjustment parameters of the bacterial decay kinetic model along the length of the CW-HSSF. Therefore, four CW-HSSFs measuring 24.0 m x 1.0 m x 0.35 m were built and filled with number 0 gravel as the support medium to a height of 0.20m. Two of the CW-HSSFs were planted with the species M. aquatica, while the other two remained uncultivated. Cultivation of M. aquatica in CW-HSSF resulted in total coliforms (TC) and Escherichia coli (EC) removals from 0.9 to 1.3 log units greater than those obtained in the uncultivated experimental plots, for the hydraulic retention times (HRTs) of 4.5 and 6.0 days. For HRT ranged from 1.5 to 6.0 days, the highest removal efficiencies in counts of TC and EC were obtained when using longer HRT. The mathematical models evaluated showed good fit to average counts of TC and EC highlighting the modified first-order kinetic model with the inclusion of the power parameter in the HRT variable.

    The occurrence and removal of fecal indicators (total coliforms (TC), fecal coliforms (FC), fecal streptococci (FS)) and pathogens (helminthes eggs) were studied in various municipal wastewater treatment processes (UASB + FPU, ASP, EA, WSP). The reductions in TC and FC concentrations were usually between 2.0 and 2.5 log units in up-flow anaerobic sludge blanket reactor incorporated with final polishing unit (UASB + FPU). Almost similar reduction was observed in activated sludge process system (ASP) and waste stabilization ponds system (WSP), while it was log 3.0 in extended aeration system (EA). UASB + FPU and WSP systems were observed more efficient to reduce helminthes eggs at almost 100%, whereas only 97% removal was observed in case of ASP and EA system. In addition to monitoring of indicator organisms, turbidity, suspended solids (SS), and biochemical oxygen demand (BOD) were used as indirect measure of the potential presence of microorganisms. Interrelationship of BOD, SS, and turbidity with fecal indicator bacteria concentration in influent and effluent manifest that improvement of the microbiological quality of wastewater is strongly linked to the removal of BOD and SS.

    Scalding has been found to lower the levels of Campylobacter on broiler carcasses. However, the numbers recovered from whole-carcass rinse samples increase following defeathering. This study was undertaken to examine the effect of a second scald applied after defeathering on microbial levels recovered from carcass rinses. Four treatments were evaluated: 1) immersion at 60 C for 28 s 30 min after defeathering, 2) immersion at 60 C for 28 s immediately after defeathering, 3) spray at 73 C for 20 s 30 min after defeathering, and 4) spray at 71 C for 20 s immediately after defeathering. As reported earlier, a significant increase in Campylobacter counts per mL whole carcass rinse was noted after carcasses were defeathered. However, when applied 30 min after defeathering, neither the immersion nor the spray second scald treatments lowered the Campylobacter counts. Likewise, neither treatment had any affect on Escherichia coli or coliform bacteria counts, even though total counts were slightly reduced by the treatments. When the second scald treatment immediately followed defeathering, the same trends were observed. Campylobacter counts after the second scald remained at the postpick levels, as did counts for E. coli and coliform bacteria, but total plate counts were slightly reduced. Overall, it would appear that a postscald treatment gentle enough not to alter the carcass appearance or meat quality would not effectively lower Campylobacter, E. coli, or coliform bacteria counts.

    Full Text Available The scientific method is a fundamental concept in science. In this exercise the scientific method is taught as a hands-on investigative laboratory experience. Students generate a hypothesis concerning the environmental distribution of coliforms, design and execute an experimental test of that hypothesis, and analyze the resulting data. The exercise is safe and straightforward. It is appropriate for use in undergraduate laboratory courses for science majors and secondary school students and undergraduate non-majors with the appropriate mathematical backgrounds. Students learn both the process by which science progresses, as well as more advanced concepts in microbiology and statistics.

El objetivo de este artículo es explorar el papel de la desinversión de tecnologías de bajo valor como estrategia para la sostenibilidad del SNS. Material y método: Revisión narrativa y discusión de las características relevantes de las estrategias de desinversión en varios países. Resultados: La desinversión es un proceso explícito mediante el cual dejan de financiarse de forma parcial o completa medicamentos, dispositivos, aparatos o procedimientos con bajo o dudoso valor clínico. Sistemas sanitarios muy dispares -como los de Australia, Nueva Zelanda, Reino Unido o Estados Unidos- han puesto en marcha estrategias de desinversión diferenciadas adaptadas a su contexto, mientras que en España se mantienen las reticencias a incorporar mecanismos explícitos para la toma de decisiones sobre la incorporación o desinversión de tecnologías sanitarias al SNS. Discusión: Desinvertir en tecnologías de bajo valor es complejo. Muchas tecnologías son sólo candidatas a desinversión parcial o su valor es objeto de controversia y, adicionalmente, existen barreras psicológicas y sociológicas a la desinversión. La implantación de estas estrategias requiere el compromiso de profesionales y administraciones sanitarias y la complicidad de pacientes y ciudadanos, compromiso que debe ser gestionado.

    To characterize the integron-harbouring Gram-negative bacteria in recreational lakes, with focus on the genetic content of integrons, antimicrobial resistance profiles and virulence-associated genes. The presence and structure of integrons in coliform bacteria isolated from the water of four recreational lakes located in Poznań, Poland, was determined by PCR method. Antimicrobial resistance testing was done by disc diffusion method. Virulence-associated genes in integron-bearing Escherichia coli isolates were detected by PCR. A total of 155 integron-bearing strains of coliform bacteria were cultured. Sequence analysis showed the presence of dfrA7, aadA1, dfrA1-aadA1, dfrA17-aadA5 and dfrA12-orfF-aadA2 gene cassette arrays in class 1 integrons and dfrA1-sat2-aadA1 in class 2 integrons. Higher frequency of integron-positive bacteria and higher antimicrobial resistance ranges were noted in colder months (January and November) compared with spring and summer months. The integron-harbouring E. coli carried up to nine virulence-associated genes, with the highest frequency of kpsMT (84.6%) and traT (783%), coding for group 2 capsule and determining human serum resistance respectively. Integron-bearing multidrug resistant coliform bacteria carrying virulence genes are present in waters of recreational lakes. This study presents antimicrobial resistance and virulence-associated genes in integron-bearing coliform bacteria present in the waters of recreational lakes, which showed that multidrug resistant bacteria with virulence traits might pose a threat to public health. Moreover, the presence of genes typical for enterotoxigenic and Shiga toxin-producing E. coli is a concern. © 2015 The Society for Applied Microbiology.

    Climate change is one of the key factors affecting the future microbiological water quality in rivers and tidal estuaries. A coupled 3D hydrodynamic and fecal coliform transport model was developed and applied to the Danshuei River estuarine system for predicting the influences of climate change on microbiological water quality. The hydrodynamic and fecal coliform model was validated using observational salinity and fecal coliform distributions. According to the analyses of the statistical error, predictions of the salinity and the fecal coliform concentration from the model simulation quantitatively agreed with the observed data. The validated model was then applied to predict the fecal coliform contamination as a result of climate change, including the change of freshwater discharge and the sea level rise. We found that the reduction of freshwater discharge under climate change scenarios resulted in an increase in the fecal coliform concentration. The sea level rise would decrease fecal coliform distributions because both the water level and the water volume increased. A reduction in freshwater discharge has a negative impact on the fecal coliform concentration, whereas a rising sea level has a positive influence on the fecal coliform contamination. An appropriate strategy for the effective microbiological management in tidal estuaries is required to reveal the persistent trends of climate in the future.

    Sanita-kun™ CC (coliform count) and EC (Escherichia coli/coliform count), sheet quantitative culture systems which can avoid chromogenic interference by lactase in food, were evaluated in comparison with conventional methods for these bacteria. Based on the results of inclusivity and exclusivity studies using 77 micro-organisms, sensitivity and specificity of both Sanita-kun™ met the criteria for ISO 16140. Both media were compared with deoxycholate agar, violet red bile agar, Merck Chromocult™ coliform agar (CCA), 3M Petrifilm™ CC and EC (PEC) and 3-tube MPN, as reference methods, in 100 naturally contaminated food samples. The correlation coefficients of both Sanita-kun™ for coliform detection were more than 0·95 for all comparisons. For E. coli detection, Sanita-kun™ EC was compared with CCA, PEC and MPN in 100 artificially contaminated food samples. The correlation coefficients for E. coli detection of Sanita-kun™ EC were more than 0·95 for all comparisons. There were no significant differences in all comparisons when conducting a one-way analysis of variance (anova). Both Sanita-kun™ significantly inhibited colour interference by lactase when inhibition of enzymatic staining was assessed using 40 natural cheese samples spiked with coliform. Our results demonstrated Sanita-kun™ CC and EC are suitable alternatives for the enumeration of coliforms and E. coli/coliforms, respectively, in a variety of foods, and specifically in fermented foods. Current chromogenic media for coliforms and Escherichia coli/coliforms have enzymatic coloration due to breaking down of chromogenic substrates by food lactase. The novel sheet culture media which have film layer to avoid coloration by food lactase have been developed for enumeration of coliforms and E. coli/coliforms respectively. In this study, we demonstrated these media had comparable performance with reference methods and less interference by food lactase. These media have a possibility not only

    A total of 720 whole, romaine lettuce heads were purchased from retail locations in the Upper Midwest and assessed for coliform and Escherichia coli contamination and for the presence of E. coli O157:H7. During a 16-month period (August 2010 through December 2011), coliform and E. coli counts were enumerated on Petrifilm, and the presence of E. coli O157:H7 and the virulence gene eae was evaluated by real-time PCR (qPCR). Over half (400 of 720) of the lettuce samples were processed with an immunomagnetic separation step before the qPCR assay. All retail lettuce samples were negative for E. coli O157:H7 when tested with the R.A.P.I.D. LT qPCR targeting a region of the O-antigen, and only two (0.28%) were positive for the eae gene when tested with LightCycler qPCR. On Petrifilm, coliform counts of most lettuce samples (96.4%) were between lettuce samples (98.2%) were lettuce heads. These results contribute to the limited recorded data and understanding of microbial contamination of whole romaine lettuce heads purchased from retail locations, specifically revealing the absence of E. coli O157:H7 and low levels of contamination with coliforms and other E. coli strains.

    Full Text Available O semiárido é caracterizado pelas irregularidades pluviais e o tratamento de águas cinza para reuso na agricultura com tecnologia ecológica é uma forma de conviver com a seca nessas regiões. Nesse contexto, a pesquisa foi realizada no distrito de Ribeira no município de Cabaceiras/PB objetivando-se avaliar a eficiência da remoção dos coliformes totais e fecais do efluente tratado nas unidades de produção agrícola através da fitorremediação. Foram realizados dois tratamentos com e sem fitorremediação, a cultura utilizada foi o capim roxo. As águas cinza eram provenientes de uma lavanderia pública. Foram coletadas amostras mensais e analisadas os coliformes total e fecal (Escherichia coli. No tratamento sem fitorremediação, os coliformes totais variaram de 1,583 x 103 a 2,0224 x 103 (UFC/100 mL e quando o tratamento tinha o auxílio do capim roxo, ou seja, com fitorremediação os coliformes totais oscilaram de 1,354 x 103 a 2,0224 x 103 (UFC/100 mL. Ocorreu uma redução significativa de Escherichia coli no tratamento com fitorremediação. A utilização da fitorremediação no tratamento de águas cinza reduziu a presença de coliformes totais e fecal, sendo assim uma alternativa viável de tratamento, proporcionando um aumento da qualidade hídrica.

    Grana, D. C.; Wilkins, J. R.

    1979-01-01

    A prototype in situ system for monitoring the levels of fecal coliforms in shallow water bodies was developed and evaluated. This system was based on the known relationship between the concentration of the coliform bacteria and the amount of hydrogen they produce during growth in a complex organic media. The prototype system consists of a sampler platform, which sits on the bottom; a surface buoy, which transmits sampler-generated data; and a shore station, which receives, displays the data, and controls the sampler. The concept of remote monitoring of fecal coliform concentrations by utilizing a system based on the electrochemical method was verified during the evaluation of the prototype.

    lrradiation of 6 kGy could make the MPN of coliform bacteria in irradated spices and dehydrated vegetables meet the demands of the national microbiological examination of food hygiene. No new irradiation-resistance organism in coliform bacteria was found in 188 spices samples treated. The mistake in the MPN of coliform bacteria detection was caused mainly by operation. The main cause was that the detected bacteria for lactose refermentation and Gram-stain tests were not picked from the same colony. (authors)

    The faecal coliforms at different sites of a hypereutrophic lake near Valencia (Albufera) were identified and their relative amounts established along an annual cycle. Using lauryl tryptose broth at 35 degrees C, followed by incubation at 44.4 degrees C in 2% brilliant green bile, Escherichia coli and Klebsiella pneumoniae are practically the only coliforms present. A positive correlation was found between the water temperature and the relative amount of these two coliforms: K. pneumoniae predominates at high water temperatures, whereas E. coli shows preponderance during the cold period. The role of K. pneumoniae as the only faecal indicator under the circumstances described in the work is emphasized and discussed.

    Full Text Available Simple synthetic culture media of liquid and solid form (X broth and X agar were tested for selective isolation of coliform bacteria. Selectivity is based on the ability of coliform bacteria to grow when the minimal medium contains simple inorganic substances as nitrogen and carbon supply. Selectivity of the media was tested by inoculation of pure cultures of different microbes belonging to the genera of Staphylococcus, Bacillus and Pseudomonas and the family Enterobacteriaceae and was found to be complete in this range. The comparative investigation of milk, camembert cheese and egg melange samples in the traditional and new media proved good applicability of X broth and X agar for an effective and selective detection of coliform bacteria. When testing pasteurized milk samples, X agar detected coliforms in significantly higher counts than violet red-bile-lactose agar.

    The use of ice cubes in beverages is common among patrons of food outlets in Malaysia although its safety for human consumption remains unclear. Hence, this study was designed to determine the presence of faecal coliforms and several useful water physicochemical parameters viz. free residual chlorine concentration, turbidity and pH in ice cubes from 30 randomly selected food outlets in Kubang Kerian, Kelantan. Faecal coliforms were found in ice cubes in 16 (53%) food outlets ranging between 1 CFU/100mL to >50 CFU/ 100mL, while in the remaining 14 (47%) food outlets, in samples of tap water as well as in commercially bottled drinking water, faecal coliforms were not detected. The highest faecal coliform counts of >50 CFU/100mL were observed in 3 (10%) food outlets followed by 11-50 CFU/100mL and 1-10 CFU/100mL in 7 (23%) and 6 (20%) food outlets, respectively. All samples recorded low free residual chlorine concentration (contamination by faecal coliforms was not detected in 47% of the samples, tap water and commercially bottled drinking water, it was concluded that (1) contamination by faecal coliforms may occur due to improper handling of ice cubes at the food outlets or (2) they may not be the water sources used for making ice cubes. Since low free residual chlorine concentrations were observed (food outlets, including that of ice cube is crucial in ensuring better food and water for human consumption.

    The aim of this study was to evaluate the Escherichia coli and coliforms level of food utensils at sixty food premises in Kuala Pilah, Malaysia. The swab technique was used to investigate the presence of E. coli and coliforms on 180 of food utensils (chopping boards: 60, knives: 60 and dish plates: 60). The results indicated that 180 of food utensils were contaminated with E. coli and coliforms. More than 60% of the coliforms were exceeded the acceptable limit compared to E. coli on the food utensils. The one-way ANOVA analysis demonstrated that the presence of E. coli and coliforms differed significantly among the three types of food utensils (knives, chopping boards, and dish plates). In conclusion, this study revealed that there are hygiene issues exist in every food premises. The food utensils are safe to use during the food preparation if the presence of E. coli and coliforms are not exceed the acceptable limit. Thus, it is recommended that the food handlers in the food premises should improve effective cleaning and sanitizing of food utensils in their daily work.

    2006-03-01

    Full Text Available Fecal coliform bacteria are the most common pollutant in rivers and streams. In Louisiana, it has been reported that 37% of surveyed river miles, 31% of lakes, and 23% of estuarine water had some level of contamination. The objective of this research was to assess the effect of surface runoff amounts and rainfall amount parameters on fecal coliform bacterial densities in Bayou Dorcheat in Louisiana. Bayou Dorcheat has been designated by the Louisiana Department of Environmental Quality as a waterway that has uses such as primary contact recreation, secondary contact recreation, propagation of fish and wildlife, agriculture and as being an outstanding natural resource water. Samples from Bayou Dorcheat were collected monthly and analyzed for the presence of fecal coliforms. Fecal coliforms isolated from these samples were identified to the species level. The analysis of the bacterial levels was performed following standard test protocols as described in Standard Methods for the Examination of Water and Wastewater. Information regarding the rainfall amounts and surface runoff amounts for the selected years was retrieved from the Louisiana Office of State Climatology. It was found that a significant increase in the fecal coliform numbers may be associated with average rainfall amounts. Possible sources of elevated coliform counts could include sewage discharges from municipal treatment plants and septic tanks, storm water overflows, and runoff from pastures and range lands. It can be concluded that nonpoint source pollution that is carried by surface runoff has a significant effect on bacterial levels in water resources.

    Coliform mastitis is a severe and sometimes fatal disease characterized by an unregulated inflammatory response. The initiation, progression, and resolution of inflammatory responses are regulated, in part, by potent oxylipid metabolites derived from polyunsaturated fatty acids. The purpose of this study was to characterize the biosynthesis and diversity of oxylipid metabolites during acute bovine coliform mastitis. Eleven cows diagnosed with naturally occurring acute systemic coliform mastitis and 13 healthy control cows, matched for lactation number and days in milk, were selected for comparison of oxylipid and free fatty acid concentrations in both milk and plasma. Oxylipids and free fatty acids were quantified using liquid chromatography-tandem mass spectrometry. All polyunsaturated fatty acids quantified in milk were elevated during coliform mastitis with linoleic acid being the most abundant. Oxylipids synthesized through the lipoxygenase and cytochrome P450 pathways accounted for the majority of the oxylipid biosynthesis. This study demonstrated a complex and diverse oxylipid network, most pronounced at the level of the mammary gland. Substrate availability, biosynthetic pathways, and degree of metabolism influence the biosynthesis of oxylipids during bovine coliform mastitis. Further studies are required to identify targets for novel interventions that modulate oxylipid biosynthesis during coliform mastitis to optimize inflammation.

    Directory of Open Access Journals (Sweden)

    Inés Ma. Barrio Cantalejo

    2006-01-01

    Full Text Available Actualmente las relaciones sanitarias se apoyan en el reconocimiento del derecho de los pacientes a participar en las decisiones sobre su salud. Esta idea es el fundamento del consentimiento informado. Sin embargo, problema surge cuando el paciente no puede participar en estas decisiones porque se halla en una situación de incapacidad. Es otro, un representante, quien debe decidir por él. En España no existe claridad sobre qué criterios deben orientar las decisiones que ha de tomar el representante. El presente artículo presenta los criterios de decisión en pacientes incapaces desarrollados por la jurisprudencia norteamericana: el criterio subjetivo, el criterio del juicio sustitutivo y el criterio del mejor interés o mayor beneficio. El criterio subjetivo consiste en seguir las directrices que el paciente dictó antes de perder la capacidad. El criterio del juicio sustitutivo trata de deducir la decisión que hubiese tomado el propio paciente si pudiera, a partir de lo que conocemos de él. El criterio del mayor beneficio intenta proteger el bienestar del paciente. Tradicionalmente el «mejor interés» ha sido defender la vida a toda costa, sin atender a otro tipo de consideraciones. Quizás sea el momento de buscar un consenso sobre lo que socialmente hoy en día se considera «mejor interés». Su significado no podrá derivarse exclusivamente del derecho a la vida, sino de la conjunción entre éste –en cantidad y calidad suficientes– y la libertad, interpretados a la luz del respeto a la dignidad de la persona.

    Full Text Available La cobertura sanitaria universal (CSU está ocupando el centro de los debates sobre las reformas de los sistemas de salud. Desde el 2.000, los desafíos planteados para cumplir con los Objetivos de Desarrollo del Milenio han señalado la necesidad de un “retorno del Estado” en el campo de la salud. Consecuentemente, se renovaron los compromisos y responsabilidades que competen a los Gobiernos en cuanto a sus obligaciones para con los ciudadanos y, con ello, una nueva forma de participación comprometida y solidaria para resolver problemas específicos e impostergables para el desarrollo de los pueblos. Con la CSU se podrá asegurar que todas las personas reciban los servicios sanitarios que necesitan, sin tener que pasar penurias financieras para pagarlos. Para que una comunidad o un país pueda alcanzar la CSU se deben cumplir varios requisitos como: un sistema de salud sólido, un sistema de financiación de los servicios de salud, acceso a medicamentos y tecnologías esenciales y personal sanitario bien capacitado. Los programas de detección neonatal forman parte esencial de todo servicio de salud. El país debe garantizar que todos los RN tengan acceso a la detección y el tratamiento oportunos, sin que las familias incurran en gastos considerables y tengan que realizar el pago directo en el momento de recibir el servicio. Paraguay está realizando grandes esfuerzos para el logro de la cobertura universal en la detección neonatal. En el presente artículo se pone de manifiesto la situación actual de la DN en el país en el contexto latinoamericano.

    Thirty-six crossbred calves (Holstein cross) of 5 days of age were used to study the effect of garlic extract feeding on their performance up to the age of 2 months (pre-ruminant stage). They were randomly allotted into treatment and control groups (18 numbers in each group). Performance was evaluated by measuring average body weight (BW) gain, feed intake (dry matter (DM), total digestible nutrient (TDN) and crude protein (CP)), feed conversion efficiency (FCE; DM, TDN and CP), faecal score, faecal coliform count and feeding cost. Diets were the same for the both groups. In addition, treatment group received garlic extract supplementation at 250 mg/kg BW per day per calf. Body weight measured weekly, feed intake measured twice daily, proximate analysis of feeds and fodders analysed weekly, faecal scores monitored daily and faecal coliform count done weekly. There was significant increase in average body weight gain, feed intake and FCE and significant decrease in severity of scours as measured by faecal score and faecal coliform count in the treatment group compared to the control group (P Feed cost per kilogramme BW gain was significantly lower in the treatment group compared to control group (P calves for better performance.

    Full Text Available The Perequê and Penedo rivers flow through the plains of Praia de Leste and fall into the sea between the municipalities of Pontal do Sul and Ponta do Poço. Both of these rivers belong to the sub-basin of Paranaguá Bay, and are constituent parts of the hydrographic basin of the Atlantic Ocean (State of Paraná. Four sites along the Perequê River (Stations 1-4 and one along the Penedo River (Station 5 were monitorated for water pollution over a 12-month period. During the period of December 1995 to November 1996, three water samples were collected from each site, placed in sterilized bottles and transported to the laboratory in ice-boxes. They were analyzed for the occurrence of total and fecal coliforms, temperature and pH. Fecal pollution was detected throughout the period of study. Coliform contamination was smaller in Station 1 and 5 than in any other sites, probably due to lesser influence from urbanized areas. Water at Station 4 was strongly contaminated due to its close proximity to a sewage canal. This study demonstrated that the Pequerê and Penedo rivers, freshwater shrimps habitats, were heavily contaminated with fecal indicator bacteria, and this occurrence was not related with temperature or pH.Os rios Perequê e Penedo têm suas fontes na planície de Praia Leste e fluem para o mar entre os municípios de Pontal do Sul e Ponta do Poço.

    Full Text Available Las autoridades de Salud Pública tienen implantados y consolidados programas de vigilancia sanitaria de aguas de consumo humano y aguas de baño, cuya finalidad es evitar riesgos para la salud de la población que consume agua o que utiliza con fines recreativos zonas de baño continentales. A la luz de los conocimientos científicos actuales, la proliferación de cianobacterias es un nuevo riesgo, que es necesario tener en cuenta en los programas de protección de la salud. En el presente trabajo, cuyo principal objetivo es conocer la presencia de cianobacterias y microcistinas en aguas utilizadas para consumo humano y baño, se muestran los resultados obtenidos en los programas de vigilancia llevados a cabo en el Área de Salud de Talavera de la Reina en los últimos cuatro años. Se ha realizado un estudio descriptivo de la presencia de cianobacterias y microcistinas, en agua bruta de la captación de dos embalses y en agua tratada a la salida de dos plantas de tratamiento de agua potable. Esto mismo se ha estudiado en otros dos embalses utilizados para baño en época estival. Para ello se han efectuado muestreos quincenales y posterior identificación y recuento de cianobacterias y determinación de microcistinas disueltas en agua mediante técnica ELISA.De los resultados de la vigilancia de aguas de consumo humano, se concluye que los valores de microcistinas detectados en los embalses no son elevados, apareciendo en menos del 6% de los muestreos efectuados y que el tratamiento aplicado en las plantas de tratamiento de agua potable, es eficaz para su eliminación. De la vigilancia de cianobacterias en el agua de baño, se concluye que a lo largo de tres temporadas, en el 48% de los muestreos realizados en las dos zonas de baño del área, se han superado las 100.000 células/ml, valor guía dado por la OMS, para valorar probabilidad moderada de efectos adversos en bañistas.Destacar que es necesario disponer de datos sobre exposición a

    Full Text Available Debido a la importancia que la inocuidad de los alimentos entraña para la salud pública, se procuró determinar la calidad microbiológica de los alimentos que consumen los usuarios de los comedores comunitarios del conurbano de Buenos Aires, Argentina. Se trata de un estudio descriptivo, cuyo universo lo conformaron tres municipios con índices medianos y altos de pobreza, de los que se extrajo al azar una muestra de 52 comedores. La información se recolectó desde abril de 1994 hasta abril de 1995 inclusive, por medio de encuestas, observaciones directas y análisis microbiológicos del agua y los alimentos servidos. Los análisis del agua y los alimentos se ajustaron, respectivamente, a las recomendaciones del Código Alimentario Argentino y de la Comisión Internacional de Especificaciones Microbiológicas para Alimentos. Los resultados se interpretaron según los valores para alimentos cocidos acordados por el Grupo de Trabajo de Control de Alimentos. La parte microbiológica del estudio mostró que en 28 (54% de los comedores la comida o el agua era inadecuada y en 11 (21%, ambas eran inadecuadas. Bacillus cereus fue la bacteria patógena que se encontró con mayor frecuencia en los alimentos analizados. Los factores significativamente asociados con condiciones microbiológicas insatisfactorias de las comidas y el agua fueron no desinfectar el agua (P = 0,009, la falta de higiene en el ambiente (P = 0,03, la presencia de roedores e insectos (P = 0,05, el sistema de provisión de materias primas (P = 0,01 y un número de usuarios menor de 100 (P = 0,008. Se concluyó que la desinfección del agua y la limpieza general de los comedores son medidas que pueden implantarse por medio de intervenciones educativas en materia de higiene y manipulación de alimentos dirigidas a los encargados y empleados de los comedores. Los resultados obtenidos también apoyan la conveniencia de incluir la evaluación sanitaria de los alimentos entre los

    Full Text Available Objetivo: comparar um método alternativo com o teste do número mais provável (NMP para detecção de coliformes totais em leite humano ordenhado. Métodos: 343 amostras de leite humano ordenhado, obtidas a partir de frascos oriundos de coleta domiciliar, recebidas pelo Banco de Leite Humano do Instituto Fernandes Figueira - IFF, por doadoras previamente orientadas, foram encaminhadas ao laboratório de controle de alimentos do IFF e empregadas na comparação de dois métodos: 1 - técnica do número mais provável, conforme descrito no Standard methods for the examination of dairy products; 2 - método alternativo proposto. Resultados: os microorganismos do grupo coliformes foram detectados em 31,2% das amostras analisadas, com populações variando de 3,0 x 100 a 1,1 x 104 coliformes totais N.M.P/ml. A comparação do teste clássico com o alternativo revelou resultados semelhantes quanto à recuperação de microorganismos coliformes em amostras de leite humano ordenhado. O método alternativo detectou a presença de coliformes totais em todas as amostras contaminadas e em quatro amostras não contaminadas, segundo o teste de NMP. Conclusão: o teste alternativo permite constatar a presença ou ausência de coliformes, tornando-se útil no controle de qualidade dos frascos de leite humano ordenhado pasteurizados, manipulados nos bancos de leite humano. Portanto, o teste de NMP pode ser substituído pelo teste alternativo, que poderá ser empregado como rotina nos bancos de leite humano, já que seu custo equivale a 1/7 do tradicional.

    Full Text Available Se evaluó el recuento de coliformes totales y Escherichia coli en canales bovinas sometidas a diferentes tratamientos que incluyeron combinaciones de los métodos de lavado, desinfección y vaporización, utilizando el diseño completamente aleatorizado de un factor con 3 repeticiones. El muestreo se realizó mediante frotis de superficie en tres áreas diferentes de la muestra (espalda, pecho y anca, que fueron posteriormente analizadas mediante el método de recuento en placa. Al aplicar secuencialmente los métodos de remoción microbiana se apreció la disminución progresiva en el recuento de coliformes totales y E. coli, y en la variabilidad de los datos, principalmente en los tratamientos C, D y E. La prueba de contrastes múltiples de Friedman mostró la inexistencia de diferencias estadísticas entre los recuentos de los tratamientos C y E en la muestra 2, indicando la ineficacia de la vaporización como coadyuvante de la acidificación para disminuir el recuento de los microorganismos de estudio. Las pruebas de comparación en muestras independientes mostraron resultados idénticos a la prueba de Friedman, excepto para el recuento de E. coli entre los tratamientos D y E, sugiriendo que la vaporización tiene efecto significativo para potenciar la disminución del recuento del microorganismo en las canales.

    A sewage sample was mixed with drinking water and subjected to low voltage (15V) electrolysis in the presence of 1% NaCl. The prepared sample was also kept in freezer with and without the presence of sodium chloride for 4-hours. Among these treatments the electrolysis proved to kill the coliforms, while the freezing reduced the bacterial content. Antibiotics sensitivity patterns revealed that certain of the coliform strains survived the freezing and thawing shocks. Nature of such surviving bacteria and need to study chemical parameters of electrolyzed water are discussed. (author)

    Full Text Available Los aranceles han dejado de representar la principal barrera al comercio exterior, debido a la reducción constante de éstos en el ámbito multilateral o bilateral. Contrariamente, las medidas no arancelarias han ido en aumento, siendo la principal preocupación para las exportaciones mundiales. En este escenario, se presentan las medidas sanitarias y fitosanitarias, las cuales sirven para proteger la salud de las personas, animales y plantas en contra de riesgos asociados con enfermedades, pestes u otros; sin embargo, por la naturaleza de las mismas pueden distorsionar el comercio hasta ser utilizadas con fines proteccionistas en favor de las industrias nacionales de los países importadores. El presente artículo cuestiona si es que a pesar de contar con una serie de acuerdos comerciales internacionales, los cuales han disminuido progresivamente los aranceles, el Perú ha logrado un acceso real al mercado del Asia-Pacífico con productos agropecuarios y pesqueros. En ese sentido, se presentan casos históricos y pendientes en materia de acceso a mercados por medidas de carácter sanitario o fitosanitario, tal como el acceso de paltas a Japón. Asimismo, se analizan las disposiciones de los acuerdos comerciales en materia de medidas sanitarias y fitosanitarias y se presentan las potenciales oportunidades que se establecen en estos acuerdos, a fin de agilizar el acceso a mercados internacionales, y que no se han aprovechado.

    In response to bacterial contamination in the Meduxnekeag River and the desire to manage the watershed to reduce contaminant sources, the Houlton Band of Maliseet Indians (HBMI) and the U.S. Geological Survey began a cooperative effort to establish a baseline of water-quality data that can be used in future studies and to indicate potential sources of nutrient and bacterial contamination. This study was conducted during the summer of 2005 in the Meduxnekeag River Basin near Houlton, Maine. Continuously recorded specific conductance can be a good indicator for water quality. Specific conductance increased downstream from the town of Houlton, between runoff events, and decreased sharply following major runoff events. Collections of discrete samples during the summer of 2005 indicated seasonal positive concentration-discharge relations for total phosphorus and total nitrogen; these results indicate that storm runoff may mobilize and transport these nutrients from the terrestrial environment to the river. Data collected by the HBMI on fecal coliform bacteria indicated that bacterial contamination enters the Meduxnekeag River from multiple paths including tributaries and surface drains (ditches) in developed areas in Houlton, Maine. The Houlton wastewater treatment discharge was not an important source of bacterial contamination. Bacteroidales-based tests for general fecal contamination (Bac32 marker) were predominantly positive in samples that had excessive fecal contamination as indicated by Enterococci density greater than 104 colony-forming units per 100 millilters. Of the 22 samples tested for Bacteroidales-based markers of human-associated fecal contamination (HF134 and HF183), 8 were positive. Of the 22 samples tested for Bacteroidales-based markers of ruminant-associated fecal contamination (CF128 and CF193), 7 were positive. Human fecal contamination was detected consistently at two sites (surface drains in urban areas in the town of Houlton) and occasionally

    This study aimed to assess the importance of quantitatively detecting Campylobacter spp. in environmental surface water. The prevalence and the quantity of Campylobacter spp., thermotolerant coliforms, and Escherichia coli in 2,471 samples collected weekly, over a 2-year period, from 13 rivers and 12 streams in the Eastern Townships, Québec, Canada, were determined. Overall, 1,071 (43%), 1,481 (60%), and 1,463 (59%) samples were positive for Campylobacter spp., thermotolerant coliforms, and E. coli, respectively. There were weak correlations between the weekly distributions of Campylobacter spp. and thermotolerant coliforms (Spearman's rho coefficient = 0.27; P = 0.008) and between the quantitative levels of the two classes of organisms (Kendall tau-b correlation coefficient = 0.233; P water samples from the Eastern Townships were also tested. Five (10%) of 53 samples from private surface wells were positive for Campylobacter jejuni, of which only 2 were positive for thermotolerant coliforms. These findings suggest that microbial monitoring of raw water by using only fecal indicator organisms is not sufficient for assessing the occurrence or the load of thermophilic Campylobacter spp. Insights into the role of environmental water as sources for sporadic Campylobacter infection will require genus-specific monitoring techniques.

    El objetivo del presente trabajo fue analizar la situación epidemiológica de la tuberculosis (TB) en la Región Sanitaria V (RSV), provincia de Buenos Aires. El estudio de tendencia permitió conocer un valor promedio de las variaciones de la tasa de incidencia (TI), calculadas por regresión lineal simple y expresadas como variación anual promedio (VAP). Se analizaron el número de casos notificados y TI por 100 000 habitantes de todas las formas de TB, los casos de TB pulmonar (TBP) y TBP confirmados por bacteriología, total casos por grupos de edad: 0 – 14; 15 – 29 y mayores de 64 años, entre el 1° de enero de 2000 al 31 de diciembre de 2011. La declinación de la TI fue menor al 5% para todas las formas de TB e inferior en las TBP confirmadas bacteriológicamente. Los casos de TBP y TI más elevadas, se concentraron en el grupo de 15 a 29 años, con tendencia estable o ligeramente ascendente de la TI en la TBP bacilífera. El mismo comportamiento presentaron los casos de TBP infantil con confirmación bacteriológica. La mayor velocidad de descenso en la TI de la TBP se produjo en este grupo de edad, mientras que en mayores de 64 años, el descenso fue sostenido en el tiempo. La TB persiste como un riesgo de salud en la RSV, con casos en edades jóvenes, por lo que sigue siendo necesario fortalecer el control de la TB en esta región. PMID:26117604

    Full Text Available OBJECTIVE: Odorous compounds produced at the biosolids composting plant in Bariloche (NW Patagonia attract a variety of insects, mainly belonging to the order Diptera. In order to characterize these flies, collected specimens were taxonomically identified, their community characteristics were described and their sanitary and synanthropic importance and autochthonous or introduced character were determined. METHODS: Sampling was performed from October 1999 until March 2000. Adults were collected using an entomological net, and larvae and puparia were obtained from the composting material and incubated to obtain adults. Richness, abundance and sex ratio were calculated. RESULTS: A total of 9 taxa of Diptera were identified: Sarconesia chlorogaster, Phaenicia sericata, Calliphora vicina, Cochliomya macellaria, Ophyra sp, Muscina stabulans, Musca domestica, Sarcophaga sp and Fannia sp. Specimens of Anthomyiidae, Acaliptratae and one larva of Eristalis tenax were also found. Ophyra sp. was the most abundant taxa. All the captured Diptera belonged to introduced taxa. Most of them are considered to be eusynanthropic and/or hemisynanthropic and have sanitary importance as they may cause myiasis and pseudomyiasis. The high number of females registered and the finding of immature stages indicated that flies can develop their complete life cycle on biosolid composting windrows. CONCLUSIONS: The characterization of flies obtained in this study may be useful for defining locations of urban or semi-urban composting facilities. It also highlights the importance of sanitary precautions at such plants.OBJETIVO: Los compuestos odoríferos producidos en la Planta de Compostaje de Biosólidos de Bariloche (NO Patagonia atraen diferentes insectos, principalmente moscas (Orden Diptera. Con el objeto de caracterizarlas, se colectaron especímenes que fueron identificados taxonómicamente. Se describieron sus características comunitarias y se determinó su importancia

    The aim of this study was to rapidly and effectively analyze coliforms, which are the most fundamental indicators of water quality for fecal pollution, using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). Coliform bacteria were isolated from municipal sewage, river water, and groundwater. For each sample, 100 isolates were determined by MALDI-TOF MS. In addition, these same 100 isolates were also identified via 16S rRNA gene sequence analysis. Obtained MALDI-TOF MS data were compared with the 16S rRNA sequencing analysis, and the validity of MALDI-TOF MS for classification of coliform bacteria was examined. The concordance rate of bacterial identification for the 100 isolates obtained by MALDI-TOF MS analysis and 16S rRNA gene sequence analysis for sewage, river water, and ground water were 96%, 74%, and 62% at the genus level, respectively. Among the sewage, river water, and ground water samples, the coliform bacterial flora were distinct. The dominant genus of coliforms in sewage, river water, and groundwater were Klebsiella spp., Enterobacter spp., and Serratia spp., respectively. We determined that MALDI-TOF MS is a rapid and accurate tool that can be used to identify coliforms. Therefore, without using conventional 16S rRNA sequencing, it is possible to rapidly and effectively classify coliforms in water using MALDI-TOF MS.

    Full Text Available A garantia do fornecimento de água potável nos serviços de alimentação é uma questão relevante para a saúde pública. Assim, o objetivo deste estudo foi avaliar a qualidade microbiológica da água destinada ao abastecimento de uma rede de lojas fast-food da cidade de Recife (PE e Região Metropolitana e comparar os resultados aos padrões estabelecidos pela Portaria nº 518/2004 do Ministério da Saúde. Mensalmente, foi analisada uma amostra proveniente de uma das torneiras da área de manipulação das oito lojas investigadas, perfazendo 96 amostras ao longo de um ano, todas coletadas em duplicata. As análises seguiram a metodologia estabelecida na American Public Health Association (APHA para realização do ensaio presuntivo utilizando o Teste Presença-Ausência, considerando-se o padrão de potabilidade determinado na legislação pertinente. Os resultados revelaram que 11,46% de todas as amostras apresentaram água contaminada por coliformes totais e 1,04% contaminação por coliformes termotolerantes. Conclui-se, portanto, que a qualidade da água disponível nos estabelecimentos produtores de alimentos estudados encontra-se em estado de alerta, uma vez que o percentual significativo das amostras analisadas mostrava-se impróprio para o consumo humano de acordo com a legislação vigente, a qual preconiza ausência de coliformes totais e termotolerantes.A guaranteed supply of clean drinking water in food outlets is a relevant subject for public health.

    Full Text Available In the dairy industry the coliforms detection can he used as indicative of hygiene production of the raw milk and the contamination after-pasteurization. The traditional methods for the enumeration of the total and faecal coliforms are laborious and needs an incubation time of 96 hours. Rapid methods for detection of these microorganisms have been developed and among them the ColsSuroit is a rapid method that gives results in 24 hours and involves defined substrates for simultaneous determination of total conforms and E. coli in water based in specific enzymatic reactions of these microorganisms. The objective of this study was to evaluate its utilization in milk. Ninety-five samples of pasteurized milk were collected from the markets in Londrina city, Parana and analyzed by the Most Probable Number (NMP enumeration using the Brilliant Green Bile Lactose Broth (BGBL and ColiSure™. There was a correlation of 0.80 betwee-n the mediums when the incubation time was 43 hours for total conforms. The low down occurrence of E. coffin the analyzed samples made impossible to comparate the performance of methods for this microorganism. Compfementary analysis showed a greater sensibility and especifity of the ColiSure™ in comparation with the BGBL. The CofiSure™ can be indicated as a substitute for the traditional method, with the advantage to be faster and easier.Na indústria láctea a detecção de microrganismos do grupo coliformes é utilizada como indicativo da higiene na produção do leite e de contaminação pós-pasteurizaçüo.

    An interlaboratory evaluation was made of the 96 h AOAC method and the 24 h A-1 procedure for the enumeration of fecal coliforms in samples of yellow corn meal, rye flour, mung beans, raw ground beef, and raw oyster homogenate. Results indicated that the efficiency of the A-1 procedure, measured in terms of recovery of fecal coliforms, and the reproducibility of that recovery were dependent on the particular food being analyzed. Accordingly, until its efficiency can be more fully demonstrated, the A-1 procedure is recommended only as a screening procedure for fecal coliforms in foods.

    This study describes the results of a randomized clinical trial investigating the effect of oxytetracycline treatment dose and mode of administration on the selection of antibiotic-resistant coliform bacteria in fecal samples from nursery pigs. Nursery pigs (pigs of 4 to 7 weeks of age) in five pig herds were treated with oxytetracycline for Lawsonia intracellularis -induced diarrhea. Each group was randomly allocated to one of five treatment groups: oral flock treatment with a (i) high (20 mg/kg of body weight), (ii) medium (10 mg/kg), or (iii) low (5 mg/kg) dose, (iv) oral pen-wise (small-group) treatment (10 mg/kg), and (v) individual intramuscular injection treatment (10 mg/kg). All groups were treated once a day for 5 days. In all groups, treatment caused a rise in the numbers and proportions of tetracycline-resistant coliform bacteria right after treatment, followed by a significant drop by the time that the pigs left the nursery unit. The counts and proportions of tetracycline-resistant coliforms did not vary significantly between treatment groups, except immediately after treatment, when the highest treatment dose resulted in the highest number of resistant coliforms. A control group treated with tiamulin did not show significant changes in the numbers or proportions of tetracycline-resistant coliforms. Selection for tetracycline-resistant coliforms was significantly correlated to selection for ampicillin- and sulfonamide-resistant strains but not to selection for cefotaxime-resistant strains. In conclusion, the difference in the dose of oxytetracycline and the way in which the drug was applied did not cause significantly different levels of selection of tetracycline-resistant coliform bacteria under the conditions tested. IMPORTANCE Antimicrobial resistance is a global threat to human health. Treatment of livestock with antimicrobials has a direct impact on this problem, and there is a need to improve the ways that we use antimicrobials in livestock

    This study assessed fecal coliform contamination in the Wachusett Reservoir Watershed in Massachusetts, USA using Soil and Water Assessment Tool (SWAT) because bacteria are one of the major water quality parameters of concern. The bacteria subroutine in SWAT, considering in-stream bacteria die-off only, was modified in this study to include solar radiation-associated die-off and the contribution of wildlife. The result of sensitivity analysis demonstrates that solar radiation is one of the most significant fate factors of fecal coliform. A water temperature-associated function to represent the contribution of beaver activity in the watershed to fecal contamination improved prediction accuracy. The modified SWAT model provides an improved estimate of bacteria from the watershed. Our approach will be useful for simulating bacterial concentrations to provide predictive and reliable information of fecal contamination thus facilitating the implementation of effective watershed management.

    Resource-limited communities throughout the developing world face significant environmental health problems related to the myriad of coliform sources within those communities. This study comprehensively investigated contamination sources and the biological and chemical mechanisms sustaining them in two adjacent communities in rural Limpopo, South Africa. An 8-month study was conducted of household ( n = 14) and source water quality, measurements of biofilm layers on the inside of household water storage containers and water transfer devices, and also hand-based coliforms and hand-washing effectiveness. A 7-day water container incubation experiment was also performed to determine the biological and chemical changes that occur in a household water storage container independent of human interference. Results indicate that household drinking water frequently becomes contaminated after collection but before consumption (197 versus 1,046 colony-forming units/100 mL; n = 266; p water treatment and other interventions aimed at maintaining the safe water chain and preventing biological regrowth.

    To investigate the effect of oral administration of two Bacillus strains on fecal coliforms, Lactobacillus and Bacillus spp. in rat animal model. An in vivo experiment was conducted for 49-day period on 36 adult male albino Wister rats divided equally into to four groups. After 7-day adaptation period, one group (T1) was fed on sterile skim milk along with basal diet for the next 28 days. Second (T2) and (T3) groups received spore biomass of Bacillus coagulans B37 and Bacillus pumilus B9, respectively, suspended in sterilized skim milk at 8-9 log colony-forming units/ml plus basal diet for 28 days, while control group (T4) was supplied with clean water along with basal diet. There was a 14-day post-treatment period. A total of 288 fecal samples (8 fecal collections per rat) were collected at every 7-day interval starting from 0 to 49 days and subjected to the enumeration of the counts of coliforms and lactobacilli and Bacillus spores using respective agar media. In vitro acid and bile tolerance tests on both the strains were performed. The rats those (T2 and T3) received either B. coagulans B37 or B. pumilus B9 spore along with non-fermented skim milk showed decrease (pBacillus spore counts as compared to the control group (T4) and the group fed only skim milk (T1). In vitro study indicated that both the strains were found to survive at pH 2.0 and 3.0 even up to 3 h and tolerate bile up to 2.0% concentration even after 12 h of exposure. This study revealed that oral administration of either B. coagulans B37 or B. pumilus B9 strains might be useful in reducing coliform counts accompanied by concurrent increase in lactobacilli counts in the intestinal flora in rats.

    Full Text Available Water borne infections in Nepal, especially in Kathmandu valley is one the major public health problems, causing thousands of deaths every year. Among three cities in the valley, the water borne infection including cholera is most predominant in Bhaktapur district. So the study was carried out to know the microbial drinking water quality in the city and to determine the prevalence of water borne infections in the specified region of the district in 2012. Altogether eighty (two samples from a single site at different interval-2/3 days water samples were collected from Bhaktapur Municipality, one of the most vulnerable regions for water borne diseases, following standard methods as described by APHA, 2010. All samples were transferred to Microbiology laboratory of Khwopa College, Dekocha, Bhaktapur and preceded immediately for Microbial analysis. The coliform density in the water samples were determined by Most Probable Number (MPN method followed by microscopy, colonial morphology and biochemical characterization. Subsequently, the presence of Vibrio cholerae, a causative agent of Cholera was analyzed in the same samples by enrichment in alkaline peptone water followed by culture on Thiosulphate citrate bile-salt sucrose (TCBS agar, a selective media for Vibrio spp. The biochemical tests were then performed to identify V. cholerae. Among eighty water samples, 87.5 percent water samples contained coliforms and half of which (45% contained feacal coliforms, Escherichia coli and remaining 12.5 percent water samples contained no coliforms. Vibrio cholerae were isolated from four water samples (5%. The drinking water quality in the region was found to be very poor. Therefore, the people in the region were suggested to treat the drinking water by using any of physical or chemical disinfection methods prior to drinking.

    The large quantities of slurry and manure that are produced annually in many areas in which cattle are raised could be an important source of organic matter and nutrients for agriculture. However, the benefits of waste recycling may be partially offset by the risk of water pollution associated with runoff from the fields to which slurry or manure has been applied. In this paper, the effects of cattle manure application on soil erosion rates and runoff and on surface water pollution by faecal coliforms are analysed. Rainfall simulations at a rate of 70 mm h(-1) were conducted in a sandy loam soil packed into soil flumes (2.5m long x 1m wide) at a bulk density of 1400 kg m(-3), with and without cattle slurry manure applied on the surface. For each simulation, sediment and runoff rates were analysed and in those simulations with applied slurry, presumptive faecal coliform (PFC) concentrations in the runoff were evaluated. The application of slurry on the soil surface appeared to have a protective effect on the soils, reducing soil detachment by up to 70% but increasing runoff volume by up to 30%. This practice implies an important source of pollution for surface waters especially if rainfall takes place within a short period after application. The concentrations of micro-organisms (presumptive faecal coliforms (PFCs)) found in water runoff ranged from 1.9 x 10(4) to 1.1 x 10(6) PFC 100mL(-1), depending on the initial concentration in the slurry, and they were particularly high during the first phases of the rainfall event. The result indicates a strong relationship between the faecal coliforms transported by runoff and the organic matter in the sediment.

    The coliform group of bacteria are consider to be one of the prominent indicators of surface/groundwater pollution as their presence in drinking water sources shows that water has been in contact with soil, plants, septic tanks or sewerage lines/drains. As a part of surface/groundwater pollution studies in various areas of Rawalpindi city coliform bacteria have been determined in the available drinking sources to evaluate their possible connection with the nearby septic tanks and sewerage lines/drains. Selective water samples were tapped from 72 domestic dug wells, and 98 municipal corporation tube-wells and associated water supply lines in some poorly drained areas of Rawalpindi. These samples were analyzed using membrane filter technique. In general, the sampled areas have indicated poor water quality w.r.t. coliform activity. 52% samples of the collected samples have indicated presence of Ecoli. Of these, 73% samples mostly collected from the poorly drained areas have shown significant counts of Ecoli. These water are rendered unfit for drinking purposes. Thirteen water samples collected indicated toxic levels of Ecoli in the municipal water supply caused due to a known leakage in the main domestic water supply line. The presence of coliform in the tube-well water supply taps are thus attributed to ruptures in the underground water supply lines. Present study reveals that general sanitary condition and water quality in the city are poor and that there is an urgent need of improvement in the water treatment and distribution systems by the concern quaters.

    The occurrence of resistance patterns among wastewater fecal coliforms was determined in the study. Susceptibility of the isolates was tested against 19 antimicrobial agents: aminoglycosides, aztreonam, carbapenems, cephalosporines, beta-lactam/beta-lactamase inhibitors, penicillines, tetracycline, trimethoprim/sulfamethoxazole, and fluoroquinolones. Additionally the removal of resistant isolates was evaluated in the laboratory-scale wastewater treatment model plant (M-WWTP), continuously supplied with the wastewater obtained from the full-scale WWTP. Number of fecal coliforms in raw (after mechanical treatment) and treated wastewater, as well as in aerobic chamber effluent was determined using selective medium. The selected strains were identified and examined for antibiotic resistance using Phoenix Automated Microbiology System (BD Biosciences, USA). The strains were identified as Escherichia coli (n=222), Klebsiella pneumoniae ssp. ozaenae (n=9), and Pantoea agglomerans (n=1). The isolate of P. agglomerans as well as 48% of E. coli isolates were sensitive to all antimicrobials tested. The most frequent resistance patterns were found for ampicillin: 100% of K. pneumoniae ssp. ozaenae and 41% of E. coli isolates. Among E. coli isolates 12% was regarded as multiple antimicrobial resistant (MAR). In the studied M-WWTP, the applied activated sludge processes reduced considerably the number of fecal coliforms, but increased the ratio of antimicrobial-resistant E. coli isolates to sensitive ones, especially among strains with MAR patterns.

    Endotoxins in grain dust, household dust, and animal bedding may induce respiratory symptoms in rodents and humans. We assayed the endotoxin, coliform, and dust levels in 20 types of rodent bedding. Endotoxin concentrations were measured by using a commercial test kit, coliform counts were determined by using conventional microbiologic procedures, and dust content was evaluated by using a rotating-tapping shaker. Paper bedding types contained significantly less endotoxin than did other bedding types; the highest levels of endotoxin were detected in hardwood and corncob beddings. The range of endotoxin content for each bedding type was: corncob bedding, 1913 to 4504 endotoxin units per gram (EU/g); hardwood bedding, 3121 to 5401 EU/g; corncob-paper mixed bedding, 1586 to 2416 EU/g; and paper bedding, less than 5 to 105 EU/g. Coliform counts varied from less than 10 to 7591 cfu/g in corncob beddings, 90 to 4010 cfu/g in corncob-paper mixed beddings, less than 10 to 137 cfu/g in hardwood beddings, and less than 10 cfu/g in paper beddings. Average dust content was less than 0.15% in all commercial bedding types. We conclude that paper bedding is the optimal bedding type for conducting LPS inhalation studies and that rodent bedding containing high levels of endotoxin may alter the results of respiratory and immunologic studies in rodents.

    Full Text Available Water was one of the natural resources, which was needed by all of living creatures. Safe drinking-water supply should be sought because there was a probability of microorganism contamination in the drinking water, such as Coliform bacteria contamination. The dangerous of Coliform bacteria was that it could cause various illnesses, such as diarrhea, typhus and bacillary dysentery. According to Indonesia National Standard 01- 3553-2006 for packaged drinking water quality requirements, the maximum acceptable contaminant level for Coliform bacteria in each 100 ml refill drinking water sample was <2/100 ml. The purpose of this research is to know or no Coliform bacteria in refill drinking-water and the amount of contaminant in MPN/100 ml, and also to find out whether the drinking-water in various refilling stations in Kayutangi Banjarmasin had fulfilled the requirements of Indonesia National Standard or not. The method of this research was quantitative descriptive research a research which described a phenomenon in a certain population. Saturation sampling technique was used to collect data, and this research used the method of Most Probable Number MPN/100 ml. The results showed that 5 (31,25% samples were positive for containing Coliform bacteria and 11 (65,78% samples were negative for containing Coliform bacteria. The highest MPN/100 ml amount of Coliform bacteria was 190 MPN/100 ml and the lowest MPN/100ml amount of Coliform bacteria was 4 MPN/100 ml. According to the calculation of colony amount using MPN/100 ml table, it was found that all of the five positive samples exceeded the Indonesia National Standard limit, in which the maximum contaminant level was <2/100 ml.

    In general, it can be said that secondary contamination in the slaughter line along with gradual increase in temperature of the chiller can increase bacterial load of both coliforms and salmonella but it will not affect the amount of psychrophile bacteria. Due to some differences between the studied slaughterhouses, microbial load of coliform and salmonella can be acheived by improving the management and installation of appropriate aquipments in the evisceration line.

    Full Text Available El objetivo del trabajo es presentar el proceso de centralización administrativa de la repartición sanitaria nacional. Para ello se analizan, en primer lugar y con la intención de situar el problema en un plazo más largo, los límites que debió afrontar el Departamento Nacional de Higiene desde el momento de su creación, en 1880, para avanzar en sus intenciones centralizadoras. Entre ellos se encuentran su escasa autonomía administrativa, las superposiciones jurisdiccionales con otras dependencias del Estado, las indefiniciones respecto de su supremacía jerárquica, la resistencia de las provincias, los municipios fuertes y las asociaciones benéficas y los conflictos de proyectos al interior mismo de la repartición. En segundo lugar se muestra cómo los sucesivos presidentes del Departamento Nacional de Higiene asumieron ese límite para su gestión y apostaron a la organización interna de la repartición antes que al desafío de la centralización de la asistencia sanitaria. Su estrategia fue el fortalecimiento de nuevas áreas de incumbencia que constituyeron una agenda que sirvió como base de la definitiva centralización de la administración sanitaria. En esta tarea contaron con el apoyo parlamentario, fundamentalmente de la bancada socialista, que logró convertir en ley durante los años 30 a una serie de nuevas atribuciones del Departamento en aspectos que ligaban la salud con la asistencia social. Por último se analiza un momento clave de este proceso, el primer ensayo de centralización sanitaria a través de la creación, en 1943, de la Dirección Nacional de Salud Pública y Asistencia Social.

    Full Text Available The aim of the present study was to evaluate the effect of the new probiotic strain Lactobacillus plantarum on chemically induced carcinogenesis in rats. Sprague dowley rats (n = 33 were divided into control and experimental groups and were fed a conventional laboratory diet. In the experimental group, rats were treated with the probiotic at the dose of 1 × 109 CFU (colony-forming units/ml. Two weeks after the beginning of the trial, N,N-dimethylhydrazine (chemical carcinogen injections were applied s.c. at the dose of 21 mg/kg b.w., 5 × weekly. At the end of the 8-month experimental period, faeces samples were taken from the rats and used for laboratory analysis. The counts of lactobacilli and coliforms and bacterial enzyme activity were determined. The probiotic strain L. plantarum as single species or in combination with oil (Lini oleum virginale decreased the count of total coliforms and increased lactobacilli in faeces of rats. Application of probiotic microorganisms significantly (P < 0.05 decreased the activities of bacterial enzymes (β-galactosidase and β-glucuronidase compared to the control group rats. The results of this study indicate that probiotic microorganisms could exert a preventive effect on colon carcinogenesis induced by N,N-dimethylhydrazine.

    This study compared the performance of a commercial chromogenic medium, CHROMagarECC (CECC), and CECC supplemented with sodium pyruvate (CECCP) with the membrane filtration lauryl sulfate-based medium (mLSA) for enumeration of Escherichia coli and non-E. coli thermotolerant coliforms (KEC). To establish that we could recover the maximum KEC and E. coli population, we compared two incubation temperature regimens, 41 and 44.5°C. Statistical analysis by the Fisher test of data did not demonstrate any statistically significant differences (P = 0.05) in the enumeration of E. coli for the different media (CECC and CECCP) and incubation temperatures. Variance analysis of data performed on KEC counts showed significant differences (P = 0.01) between KEC counts at 41 and 44.5°C on both CECC and CECCP. Analysis of variance demonstrated statistically significant differences (P = 0.05) in the enumeration of total thermotolerant coliforms (TTCs) on CECC and CECCP compared with mLSA. Target colonies were confirmed to be E. coli at a rate of 91.5% and KEC of likely fecal origin at a rate of 77.4% when using CECCP incubated at 41°C. The results of this study showed that CECCP agar incubated at 41°C is efficient for the simultaneous enumeration of E. coli and KEC from river and marine waters. PMID:10427079

    Full Text Available The diseases due of the consumption septic and unsafe nutrition are one of the major problems in developed and developing countries yet. Ice cream is a dairy product which favors the growth of microorganisms. Production of non-pasteurized hand made ice cream as traditional ice cream is very popular in Iran. In attention to more consumption of ice cream in warm seasons, especially in tropical areas, this study was conducted from the aspect of indicator microorganisms in ice cream. In this research, totally 120 samples were collected during summer of 2009 from different part of Ahvaz. According to reference methods and in order to examine Coliform and E.coli and Staphylococcus aureus contamination of samples, selective media and finally biochemical test were carried out. The results showed that 94 (78.33% and 13 (10.83% samples were contaminated to coliform and E.coli respectively, while 38 (31.67% out of 120 samples were contaminated to coagulase positive Staphylococcus aureus. The result of this study showed that in attention the standard limits, the most of the examined ice creams were not allowed for consumption. Therefore, the more seriously monitoring to prevent bacterial contaminations should be considered by responsible authorities.

    It is estimated that approximately 1.1 billion people globally drink unsafe water. We previously reported both a novel copper-alginate bead, which quickly reduces pathogen loading in waste streams and the incorporation of these beads into a novel swirl flow bioreactor (SFB), of low capital and running costs and of simple construction from commercially available plumbing pipes and fittings. The purpose of the present study was to trial this system for pathogen reduction in waste streams from an operating Dewats system in Hinjewadi, Pune, India and in both simulated and real waste streams in Seattle, Washington, USA. The trials in India, showed a complete inactivation of coliforms in the discharged effluent (Mean Log removal Value (MLRV) = 3.51), accompanied by a total inactivation of E. coli with a MLRV of 1.95. The secondary clarifier effluent also showed a 4.38 MLRV in viable coliforms during treatment. However, the system was slightly less effective in reducing E. coli viability, with a MLRV of 1.80. The trials in Seattle also demonstrated the efficacy of the system in the reduction of viable bacteria, with a LRV of 5.67 observed of viable Raoultella terrigena cells (100%).

    A major concern derived from using antimicrobials in pig production is the development of resistance. This study aimed to assess the impact of selected combinations of oral dose and duration of treatment with oxytetracycline (OTC) on selection of tetracycline resistant (TET-R) coliforms recovered from swine feces. The work encompassed two studies: 1) OTC 5mg/kg and 20mg/kg were administered to nursery pigs for 3 and 10days, respectively, under controlled experimental conditions, and 2) 10mg/kg, 20mg/kg and 30mg/kg OTC were given to a higher number of pigs for 6, 3 and 2days, respectively, under field conditions. Statistical modeling was applied to analyze trends in the proportion of TET-R coliforms. In the experimental study, no statistical difference in proportion of TET-R coliforms was observed between treatments at the end of the trial (day 18) and compared to day 0. In the field study, treatment had a significant effect on the proportion of TET-R bacteria two days after the end of treatment (2dAT) with the regimes "low dose-six days" and "medium dose-three days" yielding the highest and lowest proportions of TET-R strains, respectively. No indication of co-selection for ampicillin- and sulphonamide -R bacteria was observed for any treatment at 2dAT. By the end of the nursery period, the proportion of TET-R bacteria was not significantly different between treatments and compared to day 0. Our results suggest that similar resistance levels might be obtained by using different treatment regimes regardless of the combinations of oral dose-duration of treatment.

    Disinfection of coliform and E. Coli in water has been performed by electrolysis using carbon electrodes. Carbon electrodes were used as an anode and cathode with a purity of 98.31% based on SEM-EDS analysis. This study was conducted using electrolysis powered by electric field using carbon electrode as the anode and cathode. Electrolysis method was carried out using variations of time (30, 60, 90, 120 minutes at a voltage of 5 V) and voltage (5, 10, 15, 20 V for 30 minutes) to determine the effect of the disinfection of the bacteria. The results showed the number of coliform and E. coli in water before and after electrolysis was 190 and 22 MPN/100 mL, respectively. The standards quality of drinking water No. 492/Menkes/Per/IV/2010 requires the zero content of coliform and E. Coli. Electrolysis with the variation of time and potential can reduce the number of coliforms and E. Coli but was not in accordance with the standards. The effect of hydrogen peroxide (H2O2) to the electrochemical disinfection was determined using UV-Vis spectrophotometer. The levels of H2O2 formed increased as soon after the duration of electrolysis voltage but was not a significant influence to the mortality of coliform and E.coli.

    Pathogens in manure can cause waterborne-disease outbreaks, serious illness, and even death in humans. Therefore, information about the transformation and transport of bacteria is crucial for determining their source. In this study, the Soil and Water Assessment Tool (SWAT) was applied to simulate fecal coliform bacteria load in the Miyun Reservoir watershed, China. The data for the fecal coliform were obtained at three sampling sites, Chenying (CY), Gubeikou (GBK), and Xiahui (XH). The calibration processes of the fecal coliform were conducted using the CY and GBK sites, and validation was conducted at the XH site. An interval-to-interval approach was designed and incorporated into the processes of fecal coliform calibration and validation. The 95% confidence interval of the predicted values and the 95% confidence interval of measured values were considered during calibration and validation in the interval-to-interval approach. Compared with the traditional point-to-point comparison, this method can improve simulation accuracy. The results indicated that the simulation of fecal coliform using the interval-to-interval approach was reasonable for the watershed. This method could provide a new research direction for future model calibration and validation studies.

    Urban wastewater contains different micropollutants and high number of different microorganisms. Some bacteria in wastewater can attach to the surfaces and form biofilm, which gives bacteria advantage in fight against environmental stress. This work is focused on bacterial community analysis in biofilms isolated from influent and effluent sewerage of wastewater treatment plant in Bratislava. Biofilm microbiota detection was performed by culture-independent and culture-dependent approaches. Composition of bacterial strains was detected by denaturing gradient gel electrophoresis fingerprinting coupled with the construction of 16S rRNA clone libraries. The biofilm collected at the inlet point was characterized primarily by the presence of Pseudomonas sp., Acinetobacter sp. and Janthinobacterium sp. clones, while in the biofilm isolated at outflow of wastewater treatment plant members of Pseudomonas genus were largely detected. Beside this analysis prevalence of antibiotics and resistant coliforms, Enterococcus spp. and Staphylococcus spp. in sewerage was studied. In influent wastewater were dominant antibiotics like azithromycin, clarithromycin and ciprofloxacin. Removal efficiency of these antibiotics notably azithromycin and clarithromycin were 30% in most cases. The highest number of resistant bacteria with predominance of coliforms was detected in sample of effluent biofilm. Multidrug resistant strains in effluent biofilm showed very good ability to form biofilm. Copyright © 2018. Published by Elsevier Ltd.

    Although recent reports indicated that produce contamination with foodborne pathogens is widespread in Nigeria, the sources and magnitude of microbial contamination of fruits and vegetables on farms and in markets have not been thoroughly identified. To ascertain possible pathways of contamination, the frequency and magnitude of coliform and Escherichia coli contamination of tomatoes produced in northwest Nigeria was assessed on farms and in markets. Eight hundred twenty-six tomato fruit samples and 36 irrigation water samples were collected and assessed for fecal indicator organisms. In addition, the awareness and use of food safety practices by tomato farmers and marketers were determined. Median concentration of coliforms on all field- and market-sourced tomato fruit samples, as well as in irrigation water sources, in Kaduna, Kano, and Katsina states exceeded 1,000 most probable number (MPN) per g. Median E. coli counts from 73 (17%) of 420 field samples and 231 (57%) of 406 market tomato fruit samples exceeded 100 MPN/g. Median E. coli concentrations on tomato fruits were higher (P market tomato fruit samples (2.66 Log MPN/g) were higher (P marketers were generally unaware of the relationship between food safety practices and microbial contamination on fresh produce. Good agricultural practices pertaining to food safety on farms and in local markets were seldom used. Adoption of food safety practices on-farm, during transport, and during marketing could improve the microbial quality of tomatoes available to the public in this region of the world.

    Full Text Available Los modelos son aproximaciones, matemáticas generalmente, que permiten simular la realidad a partir de la información de los eventos principales. Su diseño adecuado permite obtener información sobre un conjunto complejo de eventos en un marco de incertidumbre. Las intervenciones farmacéuticas pueden ser analizadas mediante modelos, a partir de los datos obtenidos en estudios piloto, permitiendo estimar el valor esperado de los resultados de interés sin necesidad de realizar ulteriores estudios dotados de un mayor tamaño de muestra y/o de mayor duración del seguimiento. Las intervenciones sanitarias llevadas a cabo en el seno de procesos con unos estados de salud inicial, intermedio/s y final definidos –como es el caso de las patologías agudas-, se pueden analizar adecuadamente mediante los árboles de decisión. En el caso de intervenciones llevadas a cabo en procesos en donde el paciente puede transitar en cualquier dirección entre los diferentes estados de salud –como ocurre en las patologías crónicas-, el manejo de los árboles de decisión se hace excesivamente complejo, por lo que el problema se resuelve mediante la utilización de otro tipo de modelo de decisión, el de Markov. Sea cual sea el tipo de modelo utilizado, el análisis evaluativo de la intervención se completa mediante la realización de diversos análisis de sensibilidad, los cuales permiten estimar la sensibilidad del resultado ante la modificación de las variables más relevantes.Ello permite estimar el valor esperado de un resultado en todos rey cada uno de los escenarios que potencialmente sean posibles, así como hacer una predicción de los valores umbrales de cada variable a partir de los cuales, el resultado final cambia significativamente su tendencia. El objetivo de este capítulo es el de introducir al farmacéutico comunitario en el manejo de los modelos de decisión utilizados en la evaluación de intervenciones farmacéuticas. Para facilitar su

The significant income inequality in the use of specialized and dental services, which favor the rich, deserves policy makers' attention and further investigation related to the quality of these services.OBJETIVO: Medir y explicar las desigualdades en salud y en la utilización de la atención sanitaria relacionadas con los ingresos en Chile durante el período 2000 - 2009, evaluar sus factores determinantes y las variaciones dentro del país. MÉTODOS: Se usaron datos de las Encuestas de Caracterización Nacional Socio-económica de 2000, 2003 y 2009. La desigualdad en la utilización de la atención sanitaria relacionada con los ingresos se evaluó con los índices estandarizados de concentración para la probabilidad y el total de consultas de atención especializada, general, de urgencia, odontológica, de salud mental y hospitalaria. El estado de salud autoevaluado y las limitaciones físicas se usaron como mediciones indirectas de la necesidad de atención sanitaria. Se estandarizó por variables demográficas y de necesidad; se utilizó el método de descomposición para calcular la contribución de cada uno de los factores usados para calcular el índice de concentración, entre ellos la etnia, el estado de empleo, el seguro de salud y la región de residencia. RESULTADOS: Las personas en los quintiles de menores ingresos refirieron peor estado de salud y más limitaciones físicas que las de los quintiles superiores. Se encontraron desigualdades a favor de las personas de mayores ingresos para las consultas especializadas y odontológicas, y una leve utilización mayor en este grupo de consultas generales y totales, aunque todas han disminuido en el tiempo. La atención en salas de emergencias y las hospitalizaciones se concentraron en los quintiles de menores ingresos y han aumentado en el tiempo. Los ingresos y tener mayor educación y seguro de salud privado contribuyen a la inequidad a favor de las personas de mayores ingresos respecto de

    2010-12-01

    Jajrood River watershed is one of the main drinking water resources of the capital city of Tehran, Iran. In addition it has been available as many recreational usages especially in the warm months. As a result of being located near one of the crowded cities of the world, a variety of microbial pollutions is commonly perceived in the Jajrood River. Among them, there are strong concerns about fecal coliform bacteria concentration. This article aimed to model fate and transport of fecal coliform bacteria in Jajrood River watershed using Soil and Water Assessment Tool (SWAT) model version 2005. Potential pollutant sources in the study area were detected and quantified for modeling purposes. In spite of being lack of knowledge about bacteria die-off rate in small river bodies, as well as in other watershed-based forms, fecal coliform bacteria die-off rates were estimated using both laboratory and field data investigations with some simplifications. The SWAT model was calibrated over an extended time period (1997-2002) for this watershed. The river flow calibrated using SUFI-2 software and resulted in a very good outputs (R2=0.82, E=0.81). Furthermore SWAT model was validated over January 2003 to September 2005 in the study area and has resulted in good outputs (R2=0.61, E=0.57). This research illustrates SWAT 2005 capability to model fecal coliform bacteria in a populated watershed, and deals with most of watershed microbial pollution sources that are usually observed in developing countries. Fecal coliform concentration simulation results were mostly in the same order in comparison with real data. However, Differences were judged to be related to lack of input data. In this article different aspects of SWAT capabilities for modeling of fecal coliform bacteria concentration will be reviewed and it will present new insights in bacteria modeling procedures especially for mountainous, high populated and small sized watersheds.

    Use of the A-1M method, which was originally devised for testing water samples, has recently been extended for enumeration of fecal coliforms and Escherichia coli in shellfish and other food products. Results of our study indicate that while this method is reliable for analysis of growing waters, the use of the A-1M method for testing Pacific oysters may be less reliable because bacteria not belonging to the coliform group but which are sometimes present in these animals also give a positive reaction.

  5. Fresh steam-flaked corn in cattle feedlots is an important site for fecal coliform contamination by house flies.

    House flies are a common pest at food animal facilities, including cattle feedlots. Previously, house flies were shown to play an important role in the ecology of Escherichia coli O157:H7; house flies in cattle feedlots carried this zoonotic pathogen and were able to contaminate cattle through direct contact and/or by contamination of drinking water and feed. Because house flies aggregate in large numbers on fresh ( # 6 h) steam-flaked corn (FSFC) used in cattle feed, the aim of this study was to assess FSFC in a cattle feedlot as a potentially important site of fecal coliform contamination by house flies. House flies and FSFC samples were collected, homogenized, and processed for culturing of fecal coliforms on membrane fecal coliform agar. Selected isolates were identified by 16S rRNA gene sequencing, and representative isolates from each phylogenetic group were genotyped by pulsed-field gel electrophoresis. Fecal coliforms were undetectable in FSFC shortly (0 h) after flaking; however, in summer, after 4 to 6 h, the concentrations of fecal coliforms ranged from 1.9 × 10(3) to 3.7 × 10(4) CFU/g FSFC (mean, 1.1 ± 3.0 × 10(4) CFU/g). House flies from FSFC carried between 7.6 × 10(2) and 4.1 × 10(6) CFU of fecal coliforms per fly (mean, 6.0 ± 2.3 × 10(5) CFU per fly). Fecal coliforms were represented by E. coli (85.1%), Klebsiella spp. (10.6%), and Citrobacter spp. (4.3%). Pulsed-field gel electrophoresis demonstrated clonal matches of E. coli and Klebsiella spp. between house flies and FSFC. In contrast, in winter and in the absence of house flies, the contamination of corn by fecal coliforms was significantly (∼10-fold) lower. These results indicate that FSFC is an important site for bacterial contamination by flies and possible exchange of E. coli and other bacteria among house flies. Further research is needed to evaluate the potential use of screens or blowers to limit the access of house flies to FSFC and therefore their effectiveness in preventing

    Full Text Available El presente trabajo examina el impacto de la financiación de la asistencia sanitaria sobre las desigualdades en la oferta, el acceso y la utilización de los servicios de salud. El nuevo modelo de financiación autonómica y sanitaria, pese a las iniciales ganancias de equidad y suficiencia en el momento de su puesta en funcionamiento, introduce incertidumbre con respecto al volumen de recursos que en el futuro podrán dedicar las comunidades autónomas a la financiación de la sanidad, lo que puede originar desigualdades en la oferta de servicios y en el acceso a la asistencia sanitaria. El Fondo de Cohesión Sanitaria, diseñado para financiar la atención a los desplazados, no parece el instrumento adecuado para garantizar la igualdad de acceso a las prestaciones en el conjunto del Sistema Nacional de Salud. Por otra parte, el cambio en la composición de las fuentes de financiación de la sanidad, en la medida en que otorgue más peso a los impuestos indirectos, puede acarrear pérdidas de equidad o progresividad. Finalmente, este trabajo discute el posible impacto de la actual asignación funcional del presupuesto sanitario, excesivamente sesgada hacia el ámbito de la atención especializada, en las desigualdades en su utilización.This article summarizes the impact of health care financing instruments on inequalities of supply, access and use of health care services. Firstly, the new scheme of regional and health care financing, apart from the initial gains in terms of equity and sufficiency, introduces uncertainty about the volume of resources that will be devoted to health care facilities by the regions. This fact may cause some inter-territorial inequalities in the health care supply and the access to public services. The Health Care Cohesion Fund, which was designed to guarantee equality of access to the National Health Service, is not the optimal instrument to achieve such an ambitious goal. Secondly, the change in composition of

    This study was conducted at lab scale to determine the performance of the canal-bed for the removal of turbidity and microorganisms TC (Total Coliforms) from surface water. The canal-bed sediments were collected and analyzed for the characteristics of sediments for grain size distribution, hydraulic conductivity and the POM (Particulate Organic Matter) percent. Canal-bed sediments were containing fine particles<0.075mm in the range of 40-58%, with hydraulic conductivity averaged 7ft/day, and the POM 2.75%. The water samples collected from the canal-water have shown average POM 3.6%. Theremoval-reduction in turbidity and TC were determined through the column experiments on the canal-bed sediments. Three columns were prepared at lab-scale by using prepared canal-bed sediment as a filter-bed in the columns for the filtration of raw water samples. Fine particles of the canal-bed grain size D10 0.2 and D10 0.1mm were selected for the filter-bed formation. The prepared concentrated and diluted influent water samples containing turbidity and TC were passed through the washed filter-bed into the columns for 8-weeks filter run. The frequency of sampling and analysis were followedafter the interval of one-week run, the influent (raw water) and effluent (filtered) water samples were collected and analyzed for the turbidity and TC concentrations. The performance of the grain size D10 0.1mm have shown 95-99.95% reduction in turbidity and TC compared to the larger grain size having D10 0.2mm particles. (author)

    on the implicit scheme of the finite difference method was implemented which, when ran with MATLAB 6.1, generated values for the pollutant concentration which depend on the mentioned constants. The results obtained with the simulation were compared with the reference values to determine the longitudinal dispersion coefficient value which leads to the least residual value for each kind of support bed. The obtained results lead to the conclusion that the constructed wetland with crushed stone and chopped tires is better than the one with crushed stone alone to reduce fecal and total coliforms.

    Ellesmere Island is the northern most member of the Canadian Arctic Archipelago with over one-third of the land mass covered by ice. A joint services expedition to the island's Blue Mountains offered a unique opportunity for microbiological studies of resident bacteria in an environment uninhabited by man. Over 100 samples of water and ice were collected from stream, lake and glacier and the filtrate cultured under canvas. Bacterial growth was harvested onto swabs for transport back to the UK and 50 coliforms chosen at random for identification and antibiotic susceptibility testing. Most of the glacial strains were capsulated, pigmented and some over 2000 years old. Genera such as Serratia, Enterobacter, Klebsiella and Yersinia were found; speciation was inconclusive and some organisms remain unidentified. Ampicillin resistance was evident in 80% of water isolates as opposed to 30% of the glacial organisms, but the isolates were generally exquisitely susceptible to antibiotics. The facility for ampicillin resistance did not appear to be transferable. Plasmid DNA was found in 33% of the glacial organisms and over 50% of the water isolates. Similar profiles were identified within and apparently between species and required plasmid restriction analysis to help establish identity. Plasmid-free Serratia spp. were subjected to genomic fingerprinting. Indistinguishable patterns were found within sets of isolates both widely spaced by distance and collection date and it was postulated that coliforms able to survive an Arctic environment had spread extensively throughout the expedition area. In conclusion, this study contributes towards knowledge of naturally occurring antibiotic resistance, confirms the presence of plasmids and genotypic data provided evidence that potentially ancient organisms from glaciers can be cultured from water samples significantly distant.

    Laboratory strains of coliforms Escherichia coli and Klebsiella mobilis were used to artificially contaminate water samples in two different cultivation and detection systems, without and with bubble flow. Samples were collected with an automated system (ASCS). The positive coliform signal caused the color change into yellow (at 550-570nm). This signal could also be transmitted on-line to cell phones. E. coli containing samples emitted UV fluorescence at 480-560nm when activated by UV light. If cultivation was started with inocula varying from 10,000 to 1cfu/ml, the positive detection was obtained between 2 and 18h, respectively, in Colilert medium using Coline PMEU device without gas bubbling. Accordingly, a single K. mobilis cell produced detectable growth in 18h. Various clinical E. coli strains were compared to each other with equal inoculum sizes, and they showed slight variations in the initiation and speed of growth. The gas bubble flow in PMEU Spectrion promoted the mixing and interaction of bacteria and indicator media and speeded the onset of growth. Carbon dioxide also accelerated bacterial growth. In the presence of vancomycin, the onset of E. coli culture growth was speeded up by the volatile outlet flow from previous cultures. In the last cultivation syringe in a series of five, the lag phase disappeared and the growth of the inoculum continued without major interruption. the stimulation of the cultures by the gas flow turned out to be a useful means for improving the detection of indicator bacteria. It could also be used in combination with antibiotic selection in the broth medium. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    This study evaluated the effect of anaerobic digestion at 22, 38 and 55°C on odour, coliforms and chlortetracycline (CTC) in swine manure or monensin (MON) in cattle manure. Swine or cattle were fed the respective growth promotant, manure was collected, and 2-l laboratory methane digesters were established at the various temperatures and sampled over 25 or 28 days. After 21 days, the concentration of CTC in the 22, 38 and 55°C swine digester slurries decreased 7, 80 and 98%, respectively. Coliforms in the 22°C digester slurries were still viable after 25 days; however, they were not detectable in the 38 and 55°C slurries after 3 and 1 days, respectively. After 28 days, the concentration of MON in the 22, 38 and 55°C cattle digester slurries decreased 3, 8 and 27%, respectively. Coliforms in the 22°C cattle digester slurries were still viable after 28 days; however, they were not detectable in the 38 and 55°C slurries after 14 and 1 days, respectively. These studies indicate that anaerobic digestion at 38 or 55°C may be an effective treatment to reduce coliforms and CTC; however, it is not an effective treatment to reduce MON. More studies are needed to determine which pharmaceuticals are susceptible to degradation by a specific manure treatment to prevent negative environmental consequences. © 2012 The Authors.

    Consumption of iced beverages is common in Malaysia although specific research focusing on its safety parameters such as presence of faecal coliforms and heavy metal elements remains scarce. A study conducted in Kelantan indicated that faecal coliforms were detected in the majority of the ice cube samples analyzed, largely attributable to improper handling. Hence, it was found pertinent to conduct similar study in other parts of the country such as Johor Bahru if the similar pattern prevailed. Therefore, this present cross sectional study which randomly sampled ice cubes from 30 permanent food outlets in Taman Universiti, Johor Bahru for detecting contamination by faecal coliforms and selected heavy metal elements (lead, copper, manganese and zinc) acquires significance. Faecal coliforms were detected in 11 (36.67%) of the samples, ranging between 1 CFU/100 mL to > 50 CFU/100 mL; two of the samples were grossly contaminated (>50 CFU/100 mL). Interestingly, while positive detection of lead was observed in 29 of the 30 ice cube samples (mean: 0.511±0.105 ppm; range: 0.489-0.674 ppm), copper, manganese and zinc were not detected. In addition, analysis on commercially bottled mineral water as well as in tap water samples did not detect such contaminations. Therefore, it appears that (1) contamination of faecal coliforms in ice cubes in food outlets in Malaysia may not be sporadic in pattern but rather prevalent and (2) the source of water used for manufacturing the ice cubes that contained significant amount of lead would suggest that (3) it was neither originated from the treated tap water supply nor bottled mineral water or (4) perhaps contaminated during manufacturing process. Further studies exploring the source of water used for manufacturing these ice cubes as well as the handling process among food operators deserve consideration.

    To date, the microbiological quality of river sediments and its impact on water resources are not included in the water quality monitoring assessment. Therefore, the aim of this study was to establish genetic relatedness between faecal coliforms and enterococci isolated from the river water and riverbed sediments of Apies River to better understand the genetic similarity of microorganisms between the sediment and water phases. Indicator bacteria were subjected to a molecular study, which consisted of PCR amplification and sequence analysis of the 16S rRNA and 23S rRNA gene using specific primers for faecal coliforms and enterococci, respectively. Results revealed that the Apies River had high faecal pollution levels with enterococci showing low to moderate correlation coefficient (r 2 values ranged from 0.2605 to 0.7499) compared to the faecal coliforms which showed zero to low correlation (r 2 values ranged from 0.0027 to 0.1407) indicating that enterococci may be better indicator than faecal coliforms for detecting faecal contamination in riverbed sediments. The phylogenetic tree of faecal coliforms revealed a 98% homology among their nucleotide sequences confirming the close genetic relatedness between river water and riverbed sediment isolates. The phylogenetic tree of the enterococci showed that Enterococcus faecalis and Enterococcus faecium are the predominant species found in both river water and riverbed sediments with bootstrap values of ≥99%. A high degree of genetic relatedness between sediment and water isolates indicated a possible common ancestry and transmission pathway. We recommend the microbial monitoring of riverbed sediments as it harbours more diverse microbial community and once resuspended may cause health and environmental problems.

    A study was conducted to determine the efficacy of β-mannanase supplementation to a diet based on corn and soya bean meal (SBM) on growth performance, nutrient digestibility, blood urea nitrogen (BUN), faecal coliforms and lactic acid bacteria, and noxious gas emission in growing pigs. A total of 140 pigs [(Landrace × Yorkshire) × Duroc; average body weight 25 ± 3 kg] were randomly allotted to a 2 × 2 factorial arrangement with dietary treatments consisting of hulled or dehulled SBM without or with supplementation of 400 U β-mannanase/kg. During the 6 weeks of experimental feeding, β-mannanase supplementation had no effect on body weight gain, feed intake and gain:feed (G:F) ratio. Compared with dehulled SBM, feeding hulled SBM caused an increased feed intake of pigs in the entire trial (p = 0.05). The G:F ratio was improved in pigs receiving dehulled SBM (p < 0.05). Dietary treatments did not influence the total tract digestibility of dry matter, nitrogen and gross energy. Enzyme supplementation reduced (p < 0.05) the population of faecal coliforms and tended to reduce the NH3 concentration after 24 h of fermentation in a closed box containing faecal slurry. Feeding hulled SBM tended to reduce NH3 emission on days 3 and 5 of fermentation. In conclusion, mannanase supplementation had no influence on growth performance and nutrient digestibility but showed a positive effect on reducing coliform population and tended to reduce NH3 emission. Dehulled SBM increased G:F ratio and hulled SBM tended to reduce NH3 emission.

    MacConkey agar, standard M-FC agar, M-FC agar without rosolic acid, M-FC agar with a resuscitation top layer, Teepol agar, and pads saturated with Teepol broth, were evaluated as growth media for membrane filtration counting of fecal coliform bacteria in water. In comparative tests on 312 samples of water from a wide variety of sources, including chlorinated effluents, M-FC agar without rosolic acid proved the medium of choice because it generally yielded the highest counts, was readily obtainable, easy to prepare and handle, and yielded clearly recognizable fecal coliform colonies. Identification of 1,139 fecal coliform isolates showed that fecal coliform tests cannot be used to enumerate Escherichia coli because the incidence of E. coli among fecal coliforms varied from an average of 51% for river water to 93% for an activated sludge effluent after chlorination. The incidence of Klebsiella pneumoniae among fecal coliforms varied from an average of 4% for the activated sludge effluent after chlorination to 32% for the river water. The advantages of a standard membrane filtration procedure for routine counting of fecal coliforms in water using M-FC agar without rosolic acid as growth medium, in the absence of preincubation or resuscitation steps, are outlined.

    The presence of coliforms in processed foods is an useful indicator of post-sanitization and post processing contamination, and members of the mesophilic aerobic spore formers have great importance in food spoilage. Spore - forming aerobic bacilli have been observed in fermenting cocoa in Jamaica and West Africa. The results of this work has shown a considerable reduction of the mesophilic aerobic spore formers in irradiated Brazilian Comun Cocoa beans as long as the irradiation dose was increased from 1.05 to 3.99 kGy. The presence of coliforms irradiated has not been found even in the coroa beans with the dose of 1.05 kGy. (author). 4 refs., 1 tab.

    This study investigated the potential of laboratory- scale columns of immobilized micro-algae to disinfect effluents using thermo-tolerant coliforms (TTC) as a model system. Cells of a Chlorella species isolated from a waste stabilization pond complex in Northeast Brazil were immobilized in calcium alginate, packed into glass columns and incubated in contact with TTC suspensions for up to 24 hours. Five to six log removals of TTC were achieved in 6 hours and 11 log removals in 12 hours contact time. The results were similar under artificial light and shaded sunlight. However little or no TTC removal occurred in the light in columns of alginate beads without immobilized algae present or when the immobilized algae were incubated in the dark suggesting that the presence of both algae and light were necessary for TTC decay. There was a positive correlation between K(b) values for TTC and increasing pH in the effluent from the immobilized algal columns within the range pH 7.2 and 8.9. The potential of immobilized algal technology for wastewater disinfection may warrant further investigation.

    Manure-borne bacteria can be transported in runoff as free cells, cells attached to soil particles, and cells attached to manure particles. The objectives of this work were to compare the attachment of fecal coliforms (FC) to different soils and soil fractions and to assess the effect of bovine manure on FC attachment to soil and soil fractions. Three sand fractions of different sizes, the silt fraction, and the clay fraction of loam and sandy clay loam soils were separated and used along with soil samples in batch attachment experiments with water-FC suspensions and water-manure-FC suspensions. In the absence of manure colloids, bacterial attachment to soil, silt, and clay particles was much higher than the attachment to sand particles having no organic coating. The attachment to the coated sand particles was similar to the attachment to silt and clay. Manure colloids in suspensions decreased bacterial attachment to soils, clay and silt fractions, and coated sand fractions, but did not decrease the attachment to sand fractions without the coating. The low attachment of bacteria to silt and clay particles in the presence of manure colloids may cause predominantly free-cell transport of manure-borne FC in runoff.

    The Medini Iskandar Development is a 2300-acre multi-purpose urban development comprising residential, commercial, educational, business and recreational areas. The developer applied to the Department of Environment (DOE) Johor in July 2008 for approval of the environmental impact assessment (EIA) report for the overall Medini development. A conditional approval of the EIA report was granted by the DOE subject to some conditions, one of which stipulated that sewage effluent from the centralized sewage treatment plant (STP) is not permitted to be discharged into Sungai Pendas. A suitable location for the discharge of sewage into the Selat Johor is to be identified, based on a hydraulic and water quality modelling investigation. This modelling investigation aims to assess the impact of the discharge of treated sewage effluent on the marine water quality and on aquatic life in the Selat Johor. The supplementary EIA report was submitted to the DOE. Approval was granted in December 2011 for the construction of the marine sewage outfall and its operations. This paper presents the sampling and simulation results for key hydraulic and environmental parameters suitable for sustaining acceptable faecal coliform criteria in Selat Johor. Simulation models used include WASP7 developed by USEPA and AQUASEA developed by Vatnaskil Consulting Engineers.

    2004-01-01

    To determine how eugenol affects fermentation parameters and faecal coliforms in cattle and swine waste slurries stored anaerobically. Waste slurries (faeces:urine:water, 50:35:15) were blended with and without additives and aliquoted to triplicate 1-l flasks. Faecal coliforms were eliminated in cattle and swine waste slurries within 1 or 2 days with additions of eugenol at 10.05 mm (0.15%) and 16.75 mm (0.25%). At these concentrations volatile fatty acids (VFA) were reduced ca 70 and 50% in cattle and swine waste, respectively, over 6-8 weeks. Additionally, in cattle waste, eugenol stimulated the accumulation of lactate (>180 mm) when compared with thymol treatment (20 mm lactate). In swine waste, lactate accumulation did not occur without additives; eugenol and thymol stimulated lactate accumulation to concentrations of 22 and 32 mm, respectively. Eugenol added to cattle waste may be more beneficial than thymol because not only does it effectively control faecal coliforms and odour (VFA production), it also stimulates lactate accumulation. This in turn, causes the pH to drop more rapidly, further inhibiting microbial activity and nutrient emissions. Plant essential oils have the potential to solve some of the environmental problems associated with consolidated animal feeding operations. Thymol and eugenol reduce fermentative activity, thus, have the potential to reduce emissions of greenhouse gases and odour, and curtail transmission of pathogens in cattle and swine wastes.

    This study describes the distribution of sewage pollution markers (faecal coliforms, Clostridium perfringens and faecal sterols) in seawater and marine sediments around Rothera Research Station, Antarctic Peninsula. Untreated sewage waste has been released from this site since 1975, creating the potential for long-term contamination of the benthic environment. Faecal coliform concentrations in seawater reached background levels within 300 m of the outfall. In sediment cores, both C. perfringens and faecal coliform concentrations declined with distance from the outfall, though C. perfringens persisted at greater depths in the sediment. High concentrations of 5{beta}(H)-cholestan-3{beta}-ol (coprostanol) relative to the corresponding 5{alpha}-epimer (cholestanol), indicative of sewage pollution, were only found in sediments within 200 m of the sewage outfall. This study has shown that sewage contamination is limited to the immediate vicinity of the sewage outfall. Nevertheless, a sewage treatment plant was installed in February 2003 to reduce this contamination further. - Sewage contamination of seawater and marine sediments near Rothera Research Station (Antarctic Peninsula) was limited to the immediate vicinity of the outfall.

    Ninety beverages of three types (sugar sodas, diet sodas and water) were obtained from 20 self-service and 10 personnel-dispensed soda fountains, analyzed for microbial contamination, and evaluated with respect to U.S. drinking water regulations. A follow-up study compared the concentration and composition of microbial populations in 27 beverages collected from 9 soda fountain machines in the morning as well as in the afternoon. Ice dispensed from these machines was also examined for microbial contamination. While none of the ice samples exceeded U.S. drinking water standards, coliform bacteria was detected in 48% of the beverages and 20% had a heterotrophic plate count greater than 500cfu/ml. Statistical analyses revealed no difference in levels of microbial contamination between beverage types or between those dispensed from self-service and personnel-dispensed soda fountains. More than 11% of the beverages analyzed contained Escherichia coli and over 17% contained Chryseobacterium meningosepticum. Other opportunistic pathogenic microorganisms isolated from the beverages included species of Klebsiella, Staphylococcus, Stenotrophomonas, Candida, and Serratia. Most of the identified bacteria showed resistance to one or more of the 11 antibiotics tested. These findings suggest that soda fountain machines may harbor persistent communities of potentially pathogenic microorganisms which may contribute to episodic gastric distress in the general population and could pose a more significant health risk to immunocompromised individuals. These findings have important public health implications and signal the need for regulations enforcing hygienic practices associated with these beverage dispensers. Copyright 2009 Elsevier B.V.

    2006-05-01

    The present study was conducted with the aim of improving faecal coliform (FC) and faecal streptococcus (FS) removal efficiencies in tertiary maturation stages of a sewage treatment plant in Southern England, where climatic conditions are sub-optimal. The research used intensive field assessments (bacteriological, general quality and hydraulic) to identify the parameters that affect the bacteriological quality of the effluent from three parallel maturation ponds (North, Central and South) of similar geometry and dimensions. An engineering intervention was carried out to convert the South pond to three channels to increase the L/W ratio from 9:1 to 79:1. Hydraulic tracer studies in the South pond with Rhodamine WT showed that the dispersion number 'd' was reduced from 0.37 (dispersed flow) to 0.074 by this intervention under similar flow conditions (4.5l/s). Hydraulic retention time was thus increased by 5h, delay in jet flow short-circuiting was increased from 2.5 to 17.5h thus increasing the exposure times for all elements. As a result of the intervention FC removal increased substantially. Maximum channel-lagoon efficiency of 99.84% was obtained at 4.5l/s and 19 degrees C, when exposure to sunlight was 17 h in summer. It is concluded that the channel configuration produces a higher hydraulic efficiency than conventional maturation ponds. It is therefore recommended as a viable engineering solution which permits a low-cost upgrading of plant performance, requiring no additional land, and with minimal maintenance costs.

    The objective of this study was to investigate the potential use of bacteriophage in preventing Escherichia coli mastitis on dairies. A cocktail consisting of 4 distinct bacteriophages was generated by screening against 36 E. coli isolates from dairy cows in Washington State with clinical mastitis. The bacteriophage significantly inhibited growth of 58% of the Washington State isolates and 54% of E. coli mastitis isolates from New York State, suggesting that the cocktail of phages had a relatively broad spectrum of action against relevant strains from 2 distinct geographies. The ability to suppress bacterial growth of these isolates in a liquid growth medium was not affected by the ratio of bacteriophage particles to bacterial cells (multiplicity of infection, MOI). For those E. coli that were completely inhibited by the phage cocktail, an MOI as low as 10 had the same effect as 10 µg/mL of ceftiofur on the growth rate of E. coli over a 12-h period using optical density measurements. A 3.3- to 5.6-log reduction of growth was achieved when E. coli was co-incubated with our phage cocktail in raw milk over a 12-h period at physiologic temperature. A modified gentamicin protection assay using bovine mammary epithelial cells provided a model to test whether bacteriophage could prevent cell attachment and invasion by chronic coliform mastitis strains. Pretreatment of cell cultures with the phage cocktail significantly reduced adhesion and intracellular survival of E. coli compared with controls. When combined with a bismuth-based teat sealant, the phage cocktail was able to inhibit bacterial growth when challenged with 1.6 × 10(3) cfu/mL of a clinical mastitis E. coli strain. In vitro results show bactericidal activity by our phage in raw milk and mammary tissue culture systems. Before a bacteriophage-based dry-cow treatment becomes a potential option for dairies, in vivo studies must be able to demonstrate that a specific dose of bacteriophage can protect cows from

Sublethally injured coliform bacteria on nonrinsed shredded cabbage were either absent or they were injured at a 64-65% level when present. Rinsing of shredded cabbage with electrolyzed water containing 25ppm available chlorine reduced the coliform counts by 0.4 to 1.1 log and caused sublethal injury ranging from 42 to 77%. Pantoea ananatis was one of the species injured by chlorine stress. When shredded cabbage, nonrinsed or rinsed with electrolyzed water, was stored in air and high CO 2 atmospheres at 5°C for 7days and 10°C for 5days, coliform counts on TAL plates increased from 3.3-4.5 to 6.5-9.0 log CFU/g during storage, with the increase being greater at 10°C than at 5°C. High CO 2 of 10% and 15% reduced the bacterial growth on shredded cabbage during storage at 5°C. Although injured coliform bacteria were not found on nonrinsed shredded cabbage on the initial day, injured coliforms at a range of 49-84% were detected on samples stored in air and high CO 2 atmospheres at 5°C and 10°C. Injured cells were detected more frequently during storage at both temperatures irrespective of the CO 2 atmosphere when shredded cabbage was rinsed with electrolyzed water. These results indicated that injured coliform bacteria on shredded cabbage, either rinsed or not rinsed with electrolyzed water, exhibited different degrees of injury during storage regardless of the CO 2 atmosphere and temperature tested.

    Bacterial enteropathogens acquired from contaminated food are the principal causes of travelers' diarrhea (TD). We evaluated desserts obtained from popular restaurants in the tourist city of Guadalajara, Mexico, and Houston, Texas, to determine coliform and Escherichia coli contamination levels and presence of diarrheagenic E. coli known to be important in TD. Contamination for all organisms was seen for desserts served in Guadalajara restaurants. Desserts should be considered as potentially risky foods for development of TD among international visitors to developing regions of the world.

    Full Text Available La transferencia, a principios del año 2002, del INSALUD a todas las comunidades autónomas que no disponían todavía de las competencias sobre servicios sanitarios de la Seguridad Social cierra un ciclo de gestión sanitaria moderna en España que, no obstante, no ha tenido el dinamismo ni la capacidad de innovación de la gestión empresarial. A pesar de ello, ha conocido, en estos 25 años de existencia, un auge y florecimiento espectaculares. Los problemas de nuestro sistema sanitario, o bien están vinculados a los inherentes a un sistema público de cobertura universal, generosas prestaciones y subfinanciación clara, o son los propios de un modelo organizativo obsoleto con falta de autonomía de los centros y de los profesionales, o guardan relación con las mayores expectativas de los ciudadanos y con la enorme complejidad de la medicina del futuro. Todo ello debe abordarse desde la perspectiva de una nueva gestión propia del nuevo siglo. El Sistema Nacional de Salud es apreciado por los ciudadanos, a la vez que tiene carencias y problemas muy serios; el principal riesgo es una deslegitimación crónica y progresiva, por la que los ciudadanos pierdan la fe y la confianza en el sistema sanitario público.

    Haider, H.; Ali, W.

    2011-01-01

    A Fecal Coliform (FC) management framework is developed incorporating segmentation of river reaches, hydrodynamic and water quality models and FC management under critical winter low flow conditions for a highly polluted River Ravi. FC die-off rate in the river is determined from a field survey of a selected river reach. The travel time calculated with the help of a hydrodynamic model is 0.25 days in the selected reach. FC die-off rate (Kb) was found to be 1.2 day/sup -1/ at 20 degree C. Model calibration with monitoring data set reveals reasonable agreement of the simulation results with the measured field values under low flow conditions. Presently, the river is receiving raw wastewater and the simulation results shows very high fecal coliform levels up to 100 X 10/sup 6/ MPN/100mL in the river water. These levels are much higher than the required recreation and irrigation standards. Simulations are carried out to assess water quality for the future fecal pollution loads in year 2025 and the results reveal that up to 6 log reduction in FC is required at the wastewater out falls, whereas, 5 log reduction would be sufficient for surface drains to meet desired FC standards under low flow conditions.

    A single-step most-probable-number method for determining the number of fecal coliform bacteria present in sewage treatment plant effluents is discussed. A single growth medium based on that of Reasoner et al. (1976) and consisting of 5.0 gr. proteose peptone, 3.0 gr. yeast extract, 10.0 gr. lactose, 7.5 gr. NaCl, 0.2 gr. sodium lauryl sulfate, and 0.1 gr. sodium desoxycholate per liter is used. The pH is adjusted to 6.5, and samples are incubated at 44.5 deg C. Bacterial growth is detected either by measuring the increase with time in the electrical impedance ratio between the innoculated sample vial and an uninnoculated reference vial or by visual examination for turbidity. Results obtained by the single-step method for chlorinated and unchlorinated effluent samples are in excellent agreement with those obtained by the standard method. It is suggested that in automated treatment plants impedance ratio data could be automatically matched by computer programs with the appropriate dilution factors and most probable number tables already in the computer memory, with the corresponding result displayed as fecal coliforms per 100 ml of effluent.

    Full Text Available Total thyroidectomy is a surgery that removes all the thyroid tissue from the patient. The suspect of cancer in a thyroid nodule is the most frequent indication and it is presume when previous fine needle puncture is positive or a goiter has significant volume increase or symptomes. Less frequent indications are hyperthyroidism when it is refractory to treatment with Iodine 131 or it is contraindicated, and in cases of symptomatic thyroiditis. The thyroid gland has an important anatomic relation whith the inferior laryngeal nerve and the parathyroid glands, for this reason it is imperative to perform extremely meticulous dissection to recognize each one of these elements and ensure their preservation. It is also essential to maintain strict hemostasis, in order to avoid any postoperative bleeding that could lead to a suffocating neck hematoma, feared complication that represents a surgical emergency and endangers the patient’s life.It is essential to run a formal technique, without skipping steps, and maintain prudence and patience that should rule any surgical act.

    We developed a chemiluminometric assay of beta-galactosidase in coliform bacteria, using a phenylgalactose-substituted 1,2-dioxetane derivative as a substrate. Permeabilization of cells is required to ensure the efficient cellular uptake of this compound. By this method, one coliform seeded in 100 ml of sterile water can be detected after a 6- to 9-h propagation phase followed by a 45-min enzyme assay in the presence of polymyxin B. Compared with fluorometry and colorimetry, chemiluminometry afforded 4- and 1,000-fold increases in sensitivity and 1- and 6-h increases in the speed of detection, respectively. PMID:8534120

    Studies with the nematode model Caenorhabditis elegans have identified conserved biochemical pathways that act to modulate life span. Life span can also be influenced by the composition of the intestinal microbiome, and C. elegans life span can be dramatically influenced by its diet of Escherichia coli. Although C. elegans is typically fed the standard OP50 strain of E. coli, nematodes fed E. coli strains rendered respiratory deficient, either due to a lack coenzyme Q or the absence of ATP synthase, show significant life span extension. Here we explore the mechanisms accounting for the enhanced nematode life span in response to these diets. The intestinal load of E. coli was monitored by determination of worm-associated colony forming units (cfu/worm or coliform counts) as a function of age. The presence of GFP-expressing E. coli in the worm intestine was also monitored by fluorescence microscopy. Worms fed the standard OP50 E. coli strain have high cfu and GFP-labeled bacteria in their guts at the L4 larval stage, and show saturated coliform counts by day five of adulthood. In contrast, nematodes fed diets of respiratory deficient E. coli lacking coenzyme Q lived significantly longer and failed to accumulate bacteria within the lumen at early ages. Animals fed bacteria deficient in complex V showed intermediate coliform numbers and were not quite as long-lived. The results indicate that respiratory deficient Q-less E. coli are effectively degraded in the early adult worm, either at the pharynx or within the intestine, and do not accumulate in the intestinal tract until day ten of adulthood. The findings of this study suggest that the nematodes fed the respiratory deficient E. coli diet live longer because the delay in bacterial colonization of the gut subjects the worms to less stress compared to worms fed the OP50 E. coli diet. This work suggests that bacterial respiration can act as a virulence factor, influencing the ability of bacteria to colonize and

    Consumers increasingly use bottled water and home water treatment systems to avoid direct tap water. According to the International Bottled Water Association (IBWA), an industry trade group, 5 billion gallons of bottled water were consumed by North Americans in 2001. The principal aim of this study was to assess the microbial quality of in-house and imported bottled water for human consumption, by measurement and comparison of the concentration of bacterial endotoxin and standard cultivable methods of indicator microorganisms, specifically, heterotrophic and fecal coliform plate counts. A total of 21 brands of commercial bottled water, consisting of 10 imported and 11 in-house brands, selected at random from 96 brands that are consumed in Puerto Rico, were tested at three different time intervals. The Standard Limulus Amebocyte Lysate test, gel clot method, was used to measure the endotoxin concentrations. The minimum endotoxin concentration in 63 water samples was less than 0.0625 EU/mL, while the maximum was 32 EU/mL. The minimum bacterial count showed no growth, while the maximum was 7,500 CFU/mL. Bacterial isolates like P. fluorescens, Corynebacterium sp. J-K, S. paucimobilis, P. versicularis, A. baumannii, P. chlororaphis, F. indologenes, A. faecalis and P. cepacia were identified. Repeated measures analysis of variance demonstrated that endotoxin concentration did not change over time, while there was a statistically significant (p bacterial count over time. In addition, multiple linear regression analysis demonstrated that a unit change in the concentration of endotoxin across time was associated with a significant (p bacterial growth was not detected in some water samples, endotoxin was present. Measurement of Gram-negative bacterial endotoxins is one of the methods that have been suggested as a rapid way of determining bacteriological water quality.

Se parte de las teorías de la acción humana para poder establecer las dos corrientes que pretenden explicar la acción o no-acción de las personas. Se plantean dos principios de trabajo: es necesario conocer y contar con el ser humano, los cuales se expresan en dos premisas: "Sólo conociendo al individuo y sus circunstancias es posible una acción eficiente y permanente en salud"; y "Nadie puede cuidar la salud de otro, si éste no quiere hacerlo por si mismo". Luego se postulan las siete tesis: I - No hay uno que sabe y otro que no sabe, sino dos que saben cosas distintas. II - La educación no es sólo lo que se imparte en programas educativos, sino en toda la acción sanitaria. III - La ignorancia no es un hueco a ser llenado, sino un lleno a ser transformado. IV - La educación debe ser dialógica y participativa V - La educación debe reforzar la confianza de la gente en sí misma. VI - La educación debe procurar reforzar el modelo de conocimiento: esfuerzo-logro.VII - La educación debe fomentar la responsabilidad individual y la cooperación colectiva.This article attempts to establish some postulates to orient health education aimed at promoting community participation. Theories on human action serve as the point of departure for establishing two currents of thought explaining action or non-action by people.

    Full Text Available Runoff from agricultural lands and farm animal feedlots is one of the major sources of fecal coliforms in surface waters, and fecal coliform (FC bacteria concentrations tend to vary with season because of seasonal variations in climatic factors. However, El Niño -Southern Oscillation (ENSO events may affect the extent and patterns of seasonality in FC levels in coastal waters. Water quality monitoring data for shellfish management collected during El Niño (1990, 1992, 1997, and La Niña (1999, 2000 years were analyzed to evaluate the extent to which these events influenced Pearl River stage, and bacterial levels, water temperature, and salinity in the western part of Mississippi Sound. Models to predict FC levels in relation to various environmental factors were also developed. In 1990, 1992 and 1997, FC geometric mean counts peaked in late winter (January/February reaching 120 MPN (February 1990, 165 MPN (January 1992, and 86 MPN (January 1997, and then decreased considerably during spring and summer (1.2 – 19 MPN. Thereafter, FC abundance increased slightly in fall and early winter (1.9 – 24 MPN. Fecal coliform abundance during the 2000 La Niña year was much lower (1.0 – 10.3 MPN than in 1992 (1.2 – 165 MPN, and showed no seasonal pattern from January to August, perhaps due to the relative scarcity of rainfall in 2000. In 1995 (ENSO neutral year, peak geometric mean FC count (46 MPN was lower than during El Niño years and occurred in early spring (March. The seasonal and between year variations in FC levels determined the number of days during which the conditionally approved shellfish growing area was opened for harvesting shellfish. For example, from January to April 1997, the area was not opened for shellfish harvesting, whereas in 2000, the number of days during which the area was opened ranged from 6 - 27 (January to April to 24 - 26 (October to December

    A simple, automated microplate system for biochemical characterization of water isolates can be used to obtain fingerprints of the bacterial flora from various water samples. Mathematical models for calculating the diversities and similarities between bacterial populations are described for such fingerprints. The diversity may give information on whether an indigenous or allochthonous flora is present, and the similarities between bacterial populations, as calculated by using a population similarity coefficient (Sp), may indicate contaminations between different water samples. The system was demonstrated on coliform bacterial populations from various water samples, with or without suspected intercontamination. For unrelated water samples, the Sps were close to 0, whereas repeated samples of the same source showed Sps of 0.64 to 0.74. The Sp values from several water samples were also clustered to form a dendrogram, thus indicating the relative similarities between the bacterial populations to confirm suspected common sources of pollution.

    Urology, having been part of general surgery for centuries, was completely consolidated as a medical speciality in the middle of the XX Century as the result of years of evolution and development, and all the studies and works of certain authors that represent today the mainstays of our speciality. Valencia in the middle of the 20th century saw the birth of new hospitals including the "Ciudad Sanitaria La Fe". Alfredo Tramoyeres Cases was the first chairman of the Department of Urology. This article reviews his long and fertile professional life. We have reviewed all his scientific works. The articles have been obtained from Medicina Española, Revista Española de Cirugía Traumatológica y Ortopedia, and Archivos Españoles de Urología. His most important urological work is his doctoral thesis with the title "Sigmoid-procto-ureterostomy: personal modification" published in Valencia in 1976. For his biography we used the" Biographic and bibliographic history of the Spanish Urology over the XX century" and interviews with family members. We emphasize his thorough description of the various types of urinary diversion. He covers the topics of bladder diverticula and bladder neck disorders, in which he supports surgical treatment. Finally, he sets out the rupture of the posterior urethra and various treatments for prostate cancer at that time. Alfredo Tramoyeres Cases contributed to the definitive consolidation of our speciality in the area of Valencia during the second half of the XX century, through his long professional life, with his interesting scientific contributions.

  13. Coliform bacteria as indicators of diarrheal risk in household drinking water: systematic review and meta-analysis.

    Current guidelines recommend the use of Escherichia coli (EC) or thermotolerant ("fecal") coliforms (FC) as indicators of fecal contamination in drinking water. Despite their broad use as measures of water quality, there remains limited evidence for an association between EC or FC and diarrheal illness: a previous review found no evidence for a link between diarrhea and these indicators in household drinking water. We conducted a systematic review and meta-analysis to update the results of the previous review with newly available evidence, to explore differences between EC and FC indicators, and to assess the quality of available evidence. We searched major databases using broad terms for household water quality and diarrhea. We extracted study characteristics and relative risks (RR) from relevant studies. We pooled RRs using random effects models with inverse variance weighting, and used standard methods to evaluate heterogeneity and publication bias. We identified 20 relevant studies; 14 studies provided extractable results for meta-analysis. When combining all studies, we found no association between EC or FC and diarrhea (RR 1.26 [95% CI: 0.98, 1.63]). When analyzing EC and FC separately, we found evidence for an association between diarrhea and EC (RR: 1.54 [95% CI: 1.37, 1.74]) but not FC (RR: 1.07 [95% CI: 0.79, 1.45]). Across all studies, we identified several elements of study design and reporting (e.g., timing of outcome and exposure measurement, accounting for correlated outcomes) that could be improved upon in future studies that evaluate the association between drinking water contamination and health. Our findings, based on a review of the published literature, suggest that these two coliform groups have different associations with diarrhea in household drinking water. Our results support the use of EC as a fecal indicator in household drinking water.

    There is a desire by US consumers for eggs produced by hens in alternative production systems. As the retail shell-egg market offers these products to accommodate consumer demands, additional information is needed to ensure processing methodologies result in safe eggs from all egg sources. A study was conducted to determine if there were differences in the prevalence of coliforms, Salmonella, Listeria, and Campylobacter on and within eggs and in the environment of a sister flock of conventional cage and free-range laying hens. Microbial sampling occurred approximately every 6 wk between 20 and 79 wk of age. A random sampling of typical coliform colonies produced 371 viable isolates for biochemical identification. Twenty-nine genera or species of bacteria were identified. There was a significantly greater (P free-range nest box swabs compared with that in the free-range grass and conventional cage swab samples (number of positives: 8 nest box, 1 grass, 0 cage). Seven isolates of Listeria innocua were detected with no significant difference in prevalence between the treatments. Isolates were associated with eggshells (2 free-range floor, 1 cage) and the free-range environment (2 nest box, 2 grass). There were 21 Salmonella isolates detected between all sample locations, with no significant difference in the prevalence of Salmonella detection between the treatments. Additional studies are needed to fully understand the effect of alternative production methods on the prevalence of pathogens and coliforms associated with nest-run eggs and the production environment.

    Several mastitis-causing pathogens are able to colonize the bovine teat canal. The objective of this study was to investigate the association between the treatment of sawdust bedding with a commercial alkaline conditioner and the bacterial counts on teat skin and in the teat canal. The study used a crossover design. Ten lactating Holstein cows that were free of udder infections and mastitis were included in the study. The animals were bedded on either untreated sawdust or sawdust that had been treated with a hydrated lime-based conditioner. Once a day, fresh bedding material was added. After 3 weeks, the bedding material was removed from the cubicles, fresh bedding material was provided, and the cows were rotated between the two bedding material groups. Teat skin and teat canals were sampled using the wet and dry swab technique after weeks 1, 2, 3, 4, 5 and 6. Staphylococcus aureus, Streptococcus uberis, Escherichia coli and other coliform bacteria were detected in the resulting agar plate cultures. The treatment of the bedding material was associated with the teat skin bacterial counts of Str. uberis, Esch. coli and other coliform bacteria. An association was also found between the bedding material and the teat canal bacterial counts of coliform bacteria other than Esch. coli. For Staph. aureus, no associations with the bedding material were found. In general, the addition of a hydrated lime-based conditioner to sawdust reduces the population sizes of environmental pathogens on teat skin and in teat canals.

    Antimicrobial resistance is recognized as one of the most important global health challenges. Broilers are an important reservoir of antimicrobial resistant bacteria in general and, more particularly, extended-spectrum β-lactamases (ESBL)/AmpC-producing Enterobacteriaceae. Since contamination of 1-day-old chicks is a potential risk factor for the introduction of antimicrobial resistant Enterobacteriaceae in the broiler production chain, the presence of antimicrobial resistant coliform bacteria in broiler hatching eggs was explored in the present study. Samples from 186 hatching eggs, collected from 11 broiler breeder farms, were inoculated on MacConkey agar with or without ceftiofur and investigated for the presence of antimicrobial resistant lactose-positive Enterobacteriaceae, particularly, ESBL/AmpC-producers. Escherichia coli and Enterobacter cloacae were obtained from the eggshells in 10 out of 11 (10/11) sampled farms. The majority of the isolates were recovered from crushed eggshells after external decontamination suggesting that these bacteria are concealed from the disinfectants in the egg shell pores. Antimicrobial resistance testing revealed that approximately 30% of the isolates showed resistance to ampicillin, tetracycline, trimethoprim and sulphonamides, while the majority of isolates were susceptible to amoxicillin-clavulanic acid, nitrofurantoin, aminoglycosides, florfenicol, neomycin and apramycin. Resistance to extended-spectrum cephalosporins was detected in eight Enterobacteriaceae isolates from five different broiler breeder farms. The ESBL phenotype was confirmed by the double disk synergy test and blaSHV-12, blaTEM-52 and blaACT-39 resistance genes were detected by PCR. This report is the first to present broiler hatching eggs as carriers and a potential source of ESBL/AmpC-producing Enterobacteriaceae for broiler chicks.

    Declining oyster (Crassostrea virginica) production in the Chesapeake Bay has stimulated aquaculture based on floats for off-bottom culture. While advantages of off-bottom culture are significant, the increased use of floating containers raises public health and microbiological concerns, because oysters in floats may be more susceptible to fecal contamination from storm runoff compared to those cultured on-bottom. We conducted four commercial-scale studies with market-size oysters naturally contaminated with fecal coliforms (FC) and a candidate viral indicator, F-specific RNA (FRNA) coliphage. To facilitate sampling and to test for location effects, 12 replicate subsamples, each consisting of 15 to 20 randomly selected oysters in plastic mesh bags, were placed at four characteristic locations within a 0.6- by 3.0-m "Taylor" float, and the remaining oysters were added to a depth not exceeding 15.2 cm. The float containing approximately 3,000 oysters was relaid in the York River, Virginia, for 14 days. During relay, increases in shellfish FC densities followed rain events such that final mean levels exceeded initial levels or did not meet an arbitrary product end point of 50 FC/100 ml. FRNA coliphage densities decreased to undetectable levels within 14 days (16 to 28 degrees C) in all but the last experiment, when temperatures fell between 12 and 16 degrees C. Friedman (nonparametric analysis of variance) tests performed on FC/Escherichia coli and FRNA densities indicated no differences in counts as a function of location within the float. The public health consequences of these observations are discussed, and future research and educational needs are identified.

Using probabilistic distributions for parameters, these methods represent parameter uncertainty more effectively than deterministic models. The results of this simulation process represent the joint distribution of cost and effects in the cost-effective plane. More precisely, the cost-effectiveness ratio of each simulation is used to determine whether the ratio is cost effective in relation to the ceiling ratio. This kind of information is represented in the cost-effectiveness acceptability curve, which indicates the probability of a health technology being cost-effective for a particular quality-adjusted life year value.

    Consumption of ready-to-eat (RTE) salads has increased worldwide. Consequently, the number of outbreaks caused by food-borne pathogens, including diarrheagenic E. coli pathotypes (DEPs), associated with the consumption of RTE-salads has increased. DEPs include enterotoxigenic (ETEC), typical and atypical enteropathogenic (tEPEC, aEPEC), enteroinvasive (EIEC), enteroaggregative (EAEC), diffuse adherent (DAEC) and Shiga toxin-producing (STEC) E. coli. In less-developed areas of the world, fresh crops continue to be irrigated with untreated sewage water. The aims of this study were to evaluate the microbiological quality and prevalence of DEPs in RTE-salads of raw vegetables, purchased from restaurants at Pachuca-City, Hidalgo, Mexico, where most locally consumed vegetables are irrigated with untreated sewage water. A total of 130 salads were purchased from restaurants of three categories: A) national chain restaurants and B) local restaurants, both with the H distinctive (a recognition that the Secretary of Tourism grants to restaurants that manage supplies with high levels of hygiene); and C) local small inexpensive restaurants without H distinctive. A total of 6 restaurants were included, 2 per category (A(1-2), B(1-2), C(1-2)). Each sample was tested for the presence of faecal coliforms (FC) and E. coli by standard procedures. E. coli strains were further characterized for the presence of DEPs loci by two multiplex polymerase chain reactions. Among the 130 salad samples 99% (129) were contaminated with FC; 85% (110/129) harboured E. coli and 7% (8/110) DEPs. The amount of positive salad samples for FC and E. coli was similar between restaurants and categories. The FC mean (571 FC/g) of all samples was significantly higher (p<0.001) than the E. coli mean (63 E. coli/g). A weak correlation of 7.7% (r(2)=0.077, p=0.003) between median FC and E. coli MPN (most probable number) per sample was found. Of the 8 salad samples contaminated with DEPs, 2 were spinach salads

Results of a four year survey in the sanitary department of Talavera de la Reina are presented. A descriptive study of the presence of cyanobacteria and microcystins, in non treated water from two reservoirs at the pick up point and after treatment in the exit point from two treatment plants. The same approach has been used in two recreational summer natural water reservoirs. Every fifteen days samples were analysed for cyanobateria recount and free microcystin level determination by ELISA essay. From the results of the analysis in drinking water we concluded that microcystines levels in non treated water from reservoirs are not high, less than 6 per cent of samples showed a positive results for microcystins. Treatment was effective as no sample after treatment showed a positive result for microcystins. 48 per cent of recreational water samples showed levels above 100,000 cells per ml, which corresponds to the WHO moderate adverse effect risk guide level.

It was found that health surveillance is represented by subjects as a process that, despite the contradictions, is being constructed and lived in the job routine with signs of renovation of existing representations. Thus, health protection acquires a new understanding, deviating from the prevention limits that traditionally focus on disease in order to return to promotion itself. Also, the image of health police is displaced from punishment to health education, establishing links between normative and educative performance. Moreover, professionalism is based on responsibility and knowledge, and professional devaluation is anchored in the idea of exclusion. The results allow for an analysis of the elements that can be causing permanencies and influencing the movements of daily practice, being able to revert into a benefit for the construction of a professional profile.Estudio cualitativo, exploratorio-interpretativo con el objetivo de conocer las representaciones sociales de trabajadores acerca de la vigilancia sanitaria en la Agencia Nacional de Vigilancia Sanitaria - ANVISA, RS.

    Antibiotic-resistant bacteria are an escalating grim menace to global public health. Our aim is to phenotype and genotype antibiotic-resistant commensal Escherichia coli (E. coli) from humans, animals, and water from the same community with a ‘one-health’ approach. The samples were collected from a village belonging to demographic surveillance site of Ruxmaniben Deepchand (R.D.) Gardi Medical College Ujjain, Central India. Commensal coliforms from stool samples from children aged 1–3 years and their environment (animals, drinking water from children's households, common source- and waste-water) were studied for antibiotic susceptibility and plasmid-encoded resistance genes. E. coli isolates from human (n = 127), animal (n = 21), waste- (n = 12), source- (n = 10), and household drinking water (n = 122) carried 70%, 29%, 41%, 30%, and 30% multi-drug resistance, respectively. Extended spectrum beta-lactamase (ESBL) producers were 57% in human and 23% in environmental isolates. Co-resistance was frequent in penicillin, cephalosporin, and quinolone. Antibiotic-resistance genes blaCTX-M-9 and qnrS were most frequent. Group D-type isolates with resistance genes were mainly from humans and wastewater. Colistin resistance, or the mcr-1 gene, was not detected. The frequency of resistance, co-resistance, and resistant genes are high and similar in coliforms from humans and their environment. This emphasizes the need to mitigate antibiotic resistance with a ‘one-health’ approach. PMID:28383517

The aim of this study was to determine the phenotypic and genotypic characteristics of E. coli and antibiotic resistance of the isolates collected from qanats and springs in East-Azerbaijan province. For this purpose, 118 samples were selected from above mentioned area and examined by MPN method. The positive coliform samples were identified by phenotypic and genotypic methods. Afterwards, to determine the genetic diversity of E. coli isolates, phylogenetic typing we conducted by means of multiplex PCR. To determine the antibiotic resistance profile, antibiotic discs of Nalidixic Acid, Co-trimoxazol, Amoxicillin, Gentamaicin Ciprofloxacin, Chloramphenicol, Imipenem, Cefotaxime and Ceftazidime antibiogram were used. Based on results, 48% of the samples were evaluated as positive for coliform including 40% for E. coli and 19% for Klebsiella. Amongst 23 isolates confirmed as E. coli by PCR. Phylogenetic typing revealed  that 44% of E. coli strains belonged to type D and B2 and 56% belonged to A and B1 phylotypes. Antimicrobial susceptibility pattern showed that 92% of E. coli isolates were resistant to Amoxicillin. All E. coli isolates were sensitive to Imipenem. It was concluded that presence of pathogenic E. coli with high rate of antibacterial resistance in waters source could be considered as a human health hazard.

    Understanding the excretion and treatment of human waste (feces and urine) in low and middle income countries (LMICs) is necessary to design appropriate waste management strategies. However, excretion and treatment are often difficult to quantify due to decentralization of excreta management. We address this gap by developing a mechanistic, stochastic model to characterize phosphorus, nitrogen, biochemical oxygen demand (BOD), and fecal coliform pollution from human excreta for 108 LMICs. The model estimates excretion and treatment given three scenarios: (1) use of existing sanitation systems, (2) use of World Health Organization-defined "improved sanitation", and (3) use of best available technologies. Our model estimates that more than 10(9) kg/yr each of phosphorus, nitrogen and BOD are produced. Of this, 22(19-27)%, 11(7-15)%, 17(10-23)%, and 35 (23-47)% (mean and 95% range) BOD, nitrogen, phosphorus, and fecal coliforms, respectively, are removed by existing sanitation systems. Our model estimates that upgrading to "improved sanitation" increases mean removal slightly to between 17 and 53%. Under the best available technology scenario, only approximately 60-80% of pollutants are treated. To reduce impact of nutrient and microbial pollution on human and environmental health, improvements in both access to adequate sanitation and sanitation treatment efficiency are needed.

    Full Text Available Las redes centinela sanitarias han estado activas en nuestro país desde la década de los años ochenta, con variados objetivos, metodología y diferente grado de desarrollo en las comunidades autónomas donde se han implantado. La necesidad de normalizar el funcionamiento y de armonizar los indicadores ha propiciado un proyecto de investigación de redes centinela sanitarias españolas, uno de cuyos objetivos es establecer una guía de principios y métodos de trabajo. Se ha procedido a realizar un estudio con el método Delphi, en el que un panel de 23 expertos ha consensuado, en 3 fases consecutivas, la definición de red centinela, los objetivos, los principios que deben regirlas y otros aspectos relacionados con la organización y funcionamiento. En conjunto se plantearon 41 cuestiones sobre la base de un primer borrador, las cuales necesitaban un 80% de consenso en una primera fase y un 70% en la segunda. Todos los expertos participaron en la primera fase, 22 en la segunda y 20 en la tercera. Se alcanzó un consenso en 36 cuestiones en la primera fase y en 4 de las 5 restantes en la segunda. En la tercera fase se dio forma definitiva al documento de la guía. El método de consenso Delphi ha resultado extremadamente útil en la resolución de discrepancias y divergencias, obteniéndose una guía válida para redes centinela. Los expertos ajenos a los sistemas centinela del panel seleccionado aportaron una visión más extensa sobre los objetivos y la aplicabilidad de las redes centinela sanitarias en España.Since the eighties, health sentinel networks have been active in our country, but with a variety of objectives, methods and different development levels in the autonomous communities.

    Full Text Available La evaluación económica de tecnologías sanitarias se ha convertido en los últimos años en Europa en una herramienta de primer orden para los gestores sanitarios en sus estrategias de asignación de recursos sanitarios y de adopción de nuevas tecnologías. España fue uno de los países pioneros en realizar propuestas de estandarización metodológica aplicable a estudios de evaluación económica. No obstante, la falta de decisión política y de apoyo de los gestores sanitarios a este tipo de herramientas hizo que las propuestas cayeran en desuso. Sin embargo, lo esperable es que a medio plazo sea cada vez más habitual que las nuevas tecnologías sanitarias financiadas por el Sistema Nacional de Salud deban aportar una adecuada evidencia de su valor terapéutico y social en comparación con su coste. Llegado ese momento, los actores del sistema requerirán una serie de reglas claras y consensuadas por parte de los agentes del sistema sobre las cuestiones técnicas o metodológicas que deben respetar los estudios de evaluación de tecnologías sanitarias. Por este motivo, las presentes recomendaciones orientan sobre cómo realizar y analizar los estudios de evaluación económica de calidad. Las recomendaciones aparecen bajo 17 encabezamientos o dominios, y bajo cada recomendación hay además un comentario, en el cual se justifican y discuten las propuestas en relación con otras opciones posibles.Over the last few years, economic evaluation of health technologies has become a major tool used by European health policy decision-makers to create strategies for prioritizing the allocation of health resources and the approval of new technologies.

Examines the case of Alcoy, one of the pioneer hubs of the Spanish industrialization. The main sources of the study are the municipality budgets of Public Health and the stature of the conscripts. Results show that the starting of the sanitary reform, in the late 19th, meant not only an improvement of the conditions and the salubrity of the city, but of the resident´s state of health. Until the liberal politicians did not increase the public health and the urban infrastructures assignments on the Budgets, Alcoy suffered the initial problems of the urban penalty, with negative effects that were revealed directly in the increasing morbi-mortality and the falling stature. Data suggest a positive correlation between active public health politics and biological welfare.En este artículo analizamos los efectos que la reforma sanitaria tuvo sobre el bienestar biológico y la salud de las poblaciones españolas durante el proceso de industrialización. Examinamos el caso de Alcoy, una de las ciudades pioneras de la industrialización española. Los presupuestos municipales en salud pública y los datos de estatura de los reemplazos militares constituyen las principales fuentes para su estudio. Los resultados muestran que los comienzos de la reforma sanitaria, a finales del siglo XIX, supusieron una mejora no sólo de las condiciones ambientales y de salubridad de la ciudad, sino también del estado de salud de su población residente. Hasta que los políticos liberales no incrementaron las dotaciones presupuestarias en el campo de la salud pública y las infraestructuras urbanas, Alcoy sufrió los lastres iniciales del urban penalty con secuelas negativas que se manifestaron directamente en el aumento de la morbi-mortalidad y la caída de la estatura.

    Full Text Available The medical statements of the time show us a common opinion of the deplorable sanitary conditions of Madrid and of the most of its districts in the turn of the XIX century. This situation was so terrible that Madrid was named the «death city». In this project, using as the main sources the Healthy Demographic Statitiscs of the Town Council and of the Home Office, we aim to compare the information appeared in these statements and in the historiography studies with the one obtained by the exam of the variations in the mortality of Madrid districts between 1880 and 1931. In order to do that, this project is focused on the analyse of the changes on the general and infant mortalities and on the different Madrid districts rates of some diseases such as diarrhea and enteritis in under-2s, smallpox, diphtheria, pulmonary tuberculosis, flu and the other respiratory diseases. With all of this we try to know better its sanitary conditions in the period mentioned before.

    2003-10-01

    Full Text Available Los gastos de la atención sanitaria en los Estados Unidos de América continúan aumentando y se calcula que para 2003 habrán ascendido a US$ 1,66 mil millones. Gran parte de estas erogaciones corresponden al diagnóstico y al tratamiento de enfermedades y afecciones crónicas, como la diabetes mellitus, la obesidad y las enfermedades cardiovasculares. Sobre las entidades empleadoras recae una parte considerable de los costos asociados con estos trastornos crónicos y prevenibles. Por ejemplo, los problemas de la salud relacionados con la obesidad costaron a las empresas de ese país aproximadamente US$ 13 mil millones en 1994, de los cuales US$ 8 mil millones correspondieron a costos de seguros de salud, US$ 2,4 mil millones a licencias por enfermedad, US$ 1,8 mil millones a seguros de vida y cerca de UD$ 1 mil millones a seguros por incapacidad física. Como respuesta a esta situación, se establecen cada vez más iniciativas y programas, tanto públicos como privados, para promover conductas saludables, según indica un informe publicado en septiembre de 2003 por el Departamento de Salud y Servicios Sociales del Gobierno de los Estados Unidos. El informe revela que los empleadores comienzan a percatarse de que la falta de actividad física, el exceso de peso y la obesidad, y el consumo de tabaco menoscaban la salud y la productividad de sus empleados y, a la postre, la viabilidad financiera del negocio. Esta situación es particularmente manifiesta en los Estados Unidos, ya que una gran parte del sistema de atención sanitaria de ese país pertenece a instituciones privadas y muchos empleadores ayudan a sus trabajadores a adquirir seguros de salud privados y subsidian parcialmente el costo de esos seguros. Además de ofrecer una visión general de los esfuerzos que realizan los empleadores en los Estados Unidos para promover la salud y prevenir las enfermedades, el informe del Departamento de Salud y Servicios Sociales presenta estudios de

    Full Text Available El Real Decreto-Ley 16/2012, de 20 de abril, de “Medidas urgentes para garantizar la sostenibilidad del Sistema Nacional de Salud y mejorar la calidad y seguridad de sus prestaciones”, supuso la eliminación del derecho al acceso a la salud para las personas no inscritas en el Régimen de la Seguridad Social, poniendo así punto y final a la atención sanitaria gratuita y universal para toda la ciudadanía del Estado español. Como consecuencia de la aplicación de este Real Decreto-ley se ha generado un acceso desigual a un derecho humano básico y legalmente reconocido. Este artículo pretende ofrecer un diagnóstico del impacto de la eliminación de dicha atención en las personas inmigradas, concretamente en lo que se refiere a las mujeres, y de las consecuencias derivadas del Real Decreto-ley en materia de violencia contra las mujeres y de derechos sexuales y reproductivos.

    Enterohaemorrhagic Escherichia coli O157:H7 causes severe illness in humans, especially young children and elder people. Some 2-3% salted vegetables (called Asazuke) contaminated with E. coli O157:H7 have caused food-poisoning and even death. The viability of E. coli O157:H7 in saline water and in salted vegetables was tested. During cold and frozen storage, the apparent decrease in the number of E. coli O157:H7 was not observed. However, electron-beam irradiation (0.534, 1.097 and 2.639 kGy) caused clear decrease in the numbers of E. coli O157:H7 in frozen salted Mizuna. The number of standard plating count (SPC) and coliforms were also counted and compared with the changes in the number of E. coli O157:H7. (author)

    The purpose of this study was to assess the association of bulk tank milk standard plate counts, bulk tank coliform counts (CC), and the presence of Staphylococcus aureus in bulk tank milk with various management and farm characteristics on organic and conventional dairy farms throughout New York, Wisconsin, and Oregon. Data from size-matched organic farms (n=192), conventional nongrazing farms (n=64), and conventional grazing farms (n=36) were collected at a single visit for each farm. Of the 292 farms visited, 290 bulk tank milk samples were collected. Statistical models were created using data from all herds in the study, as well as exclusively for the organic subset of herds. Because of incomplete data, 267 of 290 herds were analyzed for total herd modeling, and 173 of 190 organic herds were analyzed for the organic herd modeling. Overall, more bulk tanks from organic farms had Staph. aureus cultured from them (62% of organic herds, 42% conventional nongrazing herds, and 43% of conventional grazing herds), whereas fewer organic herds had a high CC, defined as ≥50 cfu/mL, than conventional farms in the study. A high standard plate count (×1,000 cfu/mL) was associated with decreased body condition score of adult cows and decreased milk production in both models. Several variables were significant only in the model created using all herds or only in organic herds. The presence of Staph. aureus in the bulk tank milk was associated with fewer people treating mastitis, increased age of housing, and a higher percentage of cows with 3 or fewer teats in both the organic and total herd models. The Staph. aureus total herd model also showed a relationship with fewer first-lactation animals, higher hock scores, and less use of automatic takeoffs at milking. High bulk tank CC was related to feeding a total mixed ration and using natural service in nonlactating heifers in both models. Overall, attentive management and use of outside resources were useful with regard to CC

    Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

    Full Text Available The climatological characteristics of total ozone over Estonia based on the Total Ozone Mapping Spectrometer (TOMS data are discussed. The mean annual cycle during 1979–2000 for the site at 58.3° N and 26.5° E is compiled. The available ground-level data interpolated before TOMS, have been used for trend detection. During the last two decades, the quasi-biennial oscillation (QBO corrected systematic decrease of total ozone from February–April was 3 ± 2.6% per decade. Before 1980, a spring decrease was not detectable. No decreasing trend was found in either the late autumn ozone minimum or in the summer total ozone. The QBO related signal in the spring total ozone has an amplitude of ± 20 DU and phase lag of 20 months. Between 1987–1992, the lagged covariance between the Singapore wind and the studied total ozone was weak. The spring (April–May and summer (June–August total ozone have the best correlation (coefficient 0.7 in the yearly cycle. The correlation between the May and August total ozone is higher than the one between the other summer months. Seasonal power spectra of the total ozone variance show preferred periods with an over 95% significance level. Since 1986, during the winter/spring, the contribution period of 32 days prevails instead of the earlier dominating 26 days. The spectral densities of the periods from 4 days to 2 weeks exhibit high interannual variability.

De los informes de medicamentos, 59 fueron solicitados por la DNM. La concordancia entre las decisiones tomadas por las dos direcciones que participan en el proceso alcanzó 80%. Conclusiones La ETS se inició en el MSP en 2012 a través de la DIS. Considerando que la mayoría de informes evalúan medicamentos, es indispensable que se desarrollen informes para otros tipos de tecnologías médicas y que se difunda al máximo su desarrollo y uso. A pesar de que el nivel de concordancia entre las decisiones es elevado, es importante seguir mejorando el alcance y la calidad de los informes, así como monitorizar la incorporación y difusión de las tecnologías autorizadas y financiadas para conocer la efectividad y el impacto de la ETS en Ecuador.

  14. Total photon absorption

    The present discussion is limited to a presentation of the most recent total photonuclear absorption experiments performed with real photons at intermediate energy, and more precisely in the region of nucleon resonances. The main sources of real photons are briefly reviewed and the experimental procedures used for total photonuclear absorption cross section measurements. The main results obtained below 140 MeV photon energy as well as above 2 GeV are recalled. The experimental study of total photonuclear absorption in the nuclear resonance region (140 MeV< E<2 GeV) is still at its beginning and some results are presented

    evaluación de las políticas de salud. MÉTODOS. Se usaron los datos de la Encuesta sobre Condición de Vida en Jamaica de 2004 y 2007, representativas del país. Se midieron las desigualdades relacionadas con los ingresos mediante curvas e índices de concentración de tres variables de resultados en salud (probabilidad de enfermedad o lesión, duración de la última enfermedad y autoevaluación del estado de salud y dos variables de utilización de servicios (probabilidad de recibir atención sanitaria y número de consultas sanitarias. Se utilizaron sus contrapartes estandarizadas para medir las inequidades. Con la descomposición del índice de concentración se explica la contribución de los factores socioeconómicos y demográficos a las desigualdades. RESULTADOS. La probabilidad de enfermar y la duración de la enfermedad se concentraron en la población de menores ingresos, con una clara desigualdad a favor de las personas de mayores ingresos en la utilización de los servicios de salud. Estas desigualdades e inequidades crecieron en el período 2004 - 2007. El nivel del bienestar doméstico fue el factor único que más contribuyó a estas desigualdades; otros factores que contribuyeron de manera significativa para los resultados en salud fueron el de-sempleo y la ubicación rural y, para la utilización de los servicios, tener seguro de salud. CONCLUSIONES. A pesar de las medidas tomadas en Jamaica relacionadas con la equidad en la salud, las desigualdades en los resultados en salud y en la atención sanitaria relacionadas con los ingresos han aumentado y el grupo de población que más necesita los servicios de salud es el que menos los usa. El país requiere programas más innovadores orientados a mejorar la equidad en salud.

  17. Estimated fecal coliform bacteria concentrations using near real-time continuous water-quality and streamflow data from five stream sites in Chester County, Pennsylvania, 2007–16

    Several streams used for recreational activities, such as fishing, swimming, and boating, in Chester County, Pennsylvania, are known to have periodic elevated concentrations of fecal coliform bacteria, a type of bacteria used to indicate the potential presence of fecally related pathogens that may pose health risks to humans exposed through water contact. The availability of near real-time continuous stream discharge, turbidity, and other water-quality data for some streams in the county presents an opportunity to use surrogates to estimate near real-time concentrations of fecal coliform (FC) bacteria and thus provide some information about associated potential health risks during recreational use of streams.The U.S. Geological Survey (USGS), in cooperation with the Chester County Health Department (CCHD) and the Chester County Water Resources Authority (CCWRA), has collected discrete stream samples for analysis of FC concentrations during March–October annually at or near five gaging stations where near real-time continuous data on stream discharge, turbidity, and water temperature have been collected since 2007 (or since 2012 at 2 of the 5 stations). In 2014, the USGS, in cooperation with the CCWRA and CCHD, began to develop regression equations to estimate FC concentrations using available near real-time continuous data. Regression equations included possible explanatory variables of stream discharge, turbidity, water temperature, and seasonal factors calculated using Julian Day with base-10 logarithmic (log) transformations of selected variables.The regression equations were developed using the data from 2007 to 2015 (101–106 discrete bacteria samples per site) for three gaging stations on Brandywine Creek (West Branch Brandywine Creek at Modena, East Branch Brandywine Creek below Downingtown, and Brandywine Creek at Chadds Ford) and from 2012 to 2015 (37–38 discrete bacteria samples per site) for one station each on French Creek near Phoenixville and

    2010-06-01

    The aims of this study were to assess how different bacterial groups in bulk milk are related to bulk milk somatic cell count (SCC), bulk milk total bacterial count (TBC), and bulk milk standard plate count (SPC) and to measure the repeatability of bulk milk culturing. On 53 Dutch dairy goat farms, 3 bulk milk samples were collected at intervals of 2 wk. The samples were cultured for SPC, coliform count, and staphylococcal count and for the presence of Staphylococcus aureus. Furthermore, SCC (Fossomatic 5000, Foss, Hillerød, Denmark) and TBC (BactoScan FC 150, Foss) were measured. Staphylococcal count was correlated to SCC (r=0.40), TBC (r=0.51), and SPC (r=0.53). Coliform count was correlated to TBC (r=0.33), but not to any of the other variables. Staphylococcus aureus did not correlate to SCC. The contribution of the staphylococcal count to the SPC was 31%, whereas the coliform count comprised only 1% of the SPC. The agreement of the repeated measurements was low. This study indicates that staphylococci in goat bulk milk are related to SCC and make a significant contribution to SPC. Because of the high variation in bacterial counts, repeated sampling is necessary to draw valid conclusions from bulk milk culturing. 2010 American Dairy Science Association.

    Total lymphoid irradiation by itself can produce sufficient immunosuppression to prolong the survival of a variety of organ allografts in experimental animals. The degree of prolongation is dose-dependent and is limited by the toxicity that occurs with higher doses. Total lymphoid irradiation is more effective before transplantation than after, but when used after transplantation can be combined with pharmacologic immunosuppression to achieve a positive effect. In some animal models, total lymphoid irradiation induces an environment in which fully allogeneic bone marrow will engraft and induce permanent chimerism in the recipients who are then tolerant to organ allografts from the donor strain. If total lymphoid irradiation is ever to have clinical applicability on a large scale, it would seem that it would have to be under circumstances in which tolerance can be induced. However, in some animal models graft-versus-host disease occurs following bone marrow transplantation, and methods to obviate its occurrence probably will be needed if this approach is to be applied clinically. In recent years, patient and graft survival rates in renal allograft recipients treated with conventional immunosuppression have improved considerably, and thus the impetus to utilize total lymphoid irradiation for its immunosuppressive effect alone is less compelling. The future of total lymphoid irradiation probably lies in devising protocols in which maintenance immunosuppression can be eliminated, or nearly eliminated, altogether. Such protocols are effective in rodents. Whether they can be applied to clinical transplantation remains to be seen

    Optimality of decision rules (patterns) can be measured in many ways. One of these is referred to as length. Length signifies the number of terms in a decision rule and is optimally minimized. Another, coverage represents the width of a rule’s applicability and generality. As such, it is desirable to maximize coverage. A totally optimal decision rule is a decision rule that has the minimum possible length and the maximum possible coverage. This paper presents a method for determining the presence of totally optimal decision rules for “complete” decision tables (representations of total functions in which different variables can have domains of differing values). Depending on the cardinalities of the domains, we can either guarantee for each tuple of values of the function that totally optimal rules exist for each row of the table (as in the case of total Boolean functions where the cardinalities are equal to 2) or, for each row, we can find a tuple of values of the function for which totally optimal rules do not exist for this row.

This increase, in particular the care burden will weigh in countries development, is the result, among other factors, the transition patterns epidemiological, accompanied by an increase in life expectancy at birth. This determines the prevalence of chronic and degenerative diseases within which highlights the cardiovascular and oncological diseases. In Uruguay, the life expectancy at birth has increased from 45 in 1900-75 to end of the century. In parallel we are witnessing a progressive aging of the population, with an increasing proportion of older age groups. taking population aged 65 or more, it represented 4.5% in 1908 and reached 21.2% in 2000 Similarly, cancer mortality has increased percentage, in 2001 representing 23.8% of total deaths. Depending on age, analyzed the increased risk of developing or dying from cancer in Uruguay and its impact is weighted mortality of seven locations more frequent. For each of these locations the percentage of deaths in the population of 65 or more years is as follows: lung 60.9%, breast 60.3%, prostate 91.4%, colorecto 78.3%, 72.3% stomach, esophagus 70.3%, 72.2% pancreas, averaging 69.4% overall.

    Full Text Available FIABA ONLUS (Italian Fund for Elimination of Architectural Barriers was founded in 2000 with the aim of promoting a culture of equal opportunities and, above all, it has as its main goal to involve public and private institutions to create a really accessible and usable environment for everyone. Total accessibility, Total usability and Total mobility are key indicators to define quality of life within cities. A supportive environment that is free of architectural, cultural and psychological barriers allows everyone to live with ease and universality. In fact, people who access to goods and services in the urban context can use to their advantage time and space, so they can do their activities and can maintain relationships that are deemed significant for their social life. The main aim of urban accessibility is to raise the comfort of space for citizens, eliminating all barriers that discriminate people, and prevent from an equality of opportunity. “FIABA FUND - City of ... for the removal of architectural barriers” is an idea of FIABA that has already affected many regions of Italy as Lazio, Lombardy, Campania, Abruzzi and Calabria. It is a National project which provides for opening a bank account in the cities of referring, in which for the first time, all together, individuals and private and public institutions can make a donation to fund initiatives for the removal of architectural barriers within its own territory for a real and effective total accessibility. Last February the fund was launched in Rome with the aim of achieving a Capital without barriers and a Town European model of accessibility and usability. Urban mobility is a prerequisite to access to goods and services, and to organize activities related to daily life.

    The spreading of extended-spectrum β-lactamases (ESBL)-producing thermotolerant coliforms (TC) in the water environment is a threat to human health but little is known about ESBL-producing TCs in the Yangtze River. We received 319 ESBL-producing stains obtained from the Chongqing basin and we investigated antibiotic susceptibility, bla gene types and the presence of integrons and gene cassettes. 16.8% of TC isolates were ESBL-producing bacteria and bla TEM+CTx-M was the predominant ESBL type. 65.2% of isolates contained class 1 integrons, but only 3 carried intI 2. Gene cassettes were amplified and sequenced. aadA, drfA, cmlA, sat1, aar3 and two ORF cassettes were found. In conclusion, Yangtze River is heavily polluted by ESBL-producing TC bacteria and the combined bla gene type could enhance antibiotic resistance. Class 1 integrons were widespread in ESBL-producing isolates and play an important role in multi-drug resistance. Characterization of gene cassettes could reveal the dissemination of antibiotic resistance genes. - Yangtze River is heavily polluted by ESBL-producing TC bacteria and Class 1 integrons play an important role in multi-drug resistance.

    Optical properties of colored dissolved organic matter (CDOM) were measured as a tracer of polluted waters in a Southern California surf-zone with consistently high levels of fecal indicator bacteria. Salinity, temperature, fecal coliform, absorbance (200-700nm) and fluorescence (lambda(excitation)=350nm; lambda(emission)=360-650nm) were measured in the creek and surf-zone during a dry and rain event. Fluorescence to absorption ratios for CDOM were used to distinguish water masses, with two distinct CDOM end-members identified as creek (flu/abs=8.7+/-0.8x10(4)) and coastal (flu/abs=2.2+/-0.3x10(4)). Waters containing the same CDOM end-member had highly variable bacterial levels during the dry event, suggesting intermittent sources of bacteria added to a uniform water source, consistent with marine birds. During the rain event, increased levels of the creek end-member and bacteria indicated a second bacteria source from runoff.

    Thermotolerant coliform (TC) loadings were quantified for 49 catchments draining into the North and South Bays of Santa Catarina (SC, southeastern Brazil), an area known for its tourism and aquaculture. TC loadings were calculated based on flow measurements taken in 26 rivers. TC concentrations ere quantified based on surface water samples collected at 49 catchment outlets in 2012 and 2013. Median TC loads ranged from 3.7 × 10 3 to 6.8 × 10 8 MPN s -1 . TC loadings in the catchments increased in proportion to increases in resident human population, population density and percentage of urbanised area. Catchments with more than 60% of area covered by wastewater collection and treatment systems had higher TC loads per person than catchments with less than 25%. Based on the study catchments, these results indicate that current sewerage infrastructure is ineffective in reducing contamination of faecal origin to surface waters. These findings have important implications for the management of microbiological health hazards in bathing, recreational and shellfish aquaculture waters in the North and South Bays of Santa Catarina Island.

In totale sono state analizzate oltre 1200 procedure. La prevalenza di infezioni nosocomiali delle vie urinarie è stata del 12,28% (IC 95% 7,98-16,50%. Tutti i cateterizzati avevano un sistema di drenaggio di tipo chiuso. I modelli di regressione logistica hanno dimostrato un accresciuto rischio di mancato lavaggio delle mani in presenza di un regime di ricovero d’urgenza e in unità operativa chirurgica (p‹0,01, parimenti si è evidenziato un minor livello di controllo del meato urnario in presenza del regime del ricovero d’urgenza in unità operativa chirurgica (p‹0,01.

    Conclusioni: le raccomandazioni fornite dalla letteratura in relazione all’inserimento e alla gestione del cateterismo vescicale sono solo in parte seguite nella pratica quotidiana. In particolare il lavaggio delle mani, anche se è una procedura semplice e poco costosa risulta comunque poco seguita, soprattutto in regime di urgenze e nelle chirurgie, dove per la tipologia delle prestazioni effettuata, l’aderenza a queste procedure dovrebbe essere massima. Questi comportamenti “scorretti” rendono inefficace l’utilizzo del cateterismo vescicale a ciclo chiuso. Nonostante queste problematicità la

    Novack, D.H.; Kiley, J.P.

    1987-01-01

    The multitude of papers and conferences in recent years on the use of very large megavoltage radiation fields indicates an increased interest in total body, hemibody, and total nodal radiotherapy for various clinical situations. These include high dose total body irradiation (TBI) to destroy the bone marrow and leukemic cells and provide immunosuppression prior to a bone marrow transplant, high dose total lymphoid irradiation (TLI) prior to bone marrow transplantation in severe aplastic anemia, low dose TBI in the treatment of lymphocytic leukemias or lymphomas, and hemibody irradiation (HBI) in the treatment of advanced multiple myeloma. Although accurate provision of a specific dose and the desired degree of dose homogeneity are two of the physicist's major considerations for all radiotherapy techniques, these tasks are even more demanding for large field radiotherapy. Because most large field radiotherapy is done at an extended distance for complex patient geometries, basic dosimetry data measured at the standard distance (isocenter) must be verified or supplemented. This paper discusses some of the special dosimetric problems of large field radiotherapy, with specific examples given of the dosimetry of the TBI program for bone marrow transplant at the authors' hospital

A produção de três diferentes lotes de queijo foi acompanhada, sendo coletadas amostras de várias etapas do processamento. Além disso, amostras de queijo pertencente ao lote acompanhado foram coletadas na prateleira de um estabelecimento comercial durante seu período de validade. Os suabes coletados foram semeados em ágar sangue ovino; as amostras de água foram submetidas à Colimetria; as demais amostras foram submetidas à contagem de S. aureus, coliformes e mesófilos totais por meio de protocolos de rotina. Verificou-se que, apesar da pasteurização ter diminuído consideravelmente as populações microbianas presentes no leite cru, a falta de sanificação adequada de um equipamento que entrava em contato com o leite cru e que dá acesso ao tanque de coagulação, resultou na recontaminação da matéria-prima. Ao final do processamento, o queijo encontrava-se dentro dos padrões exigidos pela legislação, contudo a elevada contagem de mesófilos totais sugere que sejam melhoradas as medidas de sanitização durante o processamento, a fim de garantir a qualidade higiênica e uma maior vida de prateleira ao queijo produzido.The aim of this study was to evaluate the hygienic conditions throughout the manufacture process of a goat unripened cheese, using the enumeration of coliforms, S. aureus and aerobic mesofilic bacteria as indicators.

    Frederickson, Paul O.

    1988-01-01

    Four totally parallel algorithms for the solution of a sparse linear system have common characteristics which become quite apparent when they are implemented on a highly parallel hypercube such as the CM2. These four algorithms are Parallel Superconvergent Multigrid (PSMG) of Frederickson and McBryan, Robust Multigrid (RMG) of Hackbusch, the FFT based Spectral Algorithm, and Parallel Cyclic Reduction. In fact, all four can be formulated as particular cases of the same totally parallel multilevel algorithm, which are referred to as TPMA. In certain cases the spectral radius of TPMA is zero, and it is recognized to be a direct algorithm. In many other cases the spectral radius, although not zero, is small enough that a single iteration per timestep keeps the local error within the required tolerance.

    Full Text Available La transferencia, a principios del año 2002, del INSALUD a todas las comunidades autónomas que no disponían todavía de las competencias sobre servicios sanitarios de la Seguridad Social cierra un ciclo de gestión sanitaria moderna en España que, no obstante, no ha tenido el dinamismo ni la capacidad de innovación de la gestión empresarial. A pesar de ello, ha conocido, en estos 25 años de existencia, un auge y florecimiento espectaculares. Los problemas de nuestro sistema sanitario, o bien están vinculados a los inherentes a un sistema público de cobertura universal, generosas prestaciones y subfinanciación clara, o son los propios de un modelo organizativo obsoleto con falta de autonomía de los centros y de los profesionales, o guardan relación con las mayores expectativas de los ciudadanos y con la enorme complejidad de la medicina del futuro. Todo ello debe abordarse desde la perspectiva de una nueva gestión propia del nuevo siglo. El Sistema Nacional de Salud es apreciado por los ciudadanos, a la vez que tiene carencias y problemas muy serios; el principal riesgo es una deslegitimación crónica y progresiva, por la que los ciudadanos pierdan la fe y la confianza en el sistema sanitario público.At the beginning of 2002, the transference of authority over public health care services from the Spanish national health System (INSALUD to all the autonomous communities hitherto lacking this authority closed a period of modern halthcare management in Spain which, nevertheless, had lacked tye dynamism and innovative capacity of business management.

    Full Text Available El Instituto de Salud Carlos III es la sede de los Institutos Nacionales de Sanidad en España, con un componente muy importante de investigación científica en áreas relacionadas con la salud, tales como las enfermedades infecciosas, el cáncer, las enfermedades cardiovasculares y la sanidad ambiental, así como de vigilancia e investigación epidemiológica. Este artículo describe el desarrollo de los Institutos de Salud Pública, que se originan con la introducción y afianzamiento de la Medicina de Laboratorio y Científica, basada en la incorporación a la práctica sanitaria, de la vacunación antivariólica, el saneamiento y el control del agua y de los alimentos. Aproximadamente en la misma época, se producen los grandes descubrimientos de la microbiología y de la inmunología que se funden con los avances prácticos en el control de productos. Para hacer frente a las necesidades de orden práctico, se crearon instituciones con responsabilidad para el mantenimiento y provisión de la vacuna antivariólica, pero que incorporaron pronto la producción de sueros y otras vacunas, así como el control de aguas, del saneamiento y de los alimentos, a medida que los avances científicos lo permitían. Al mismo tiempo, la colonización de África, la exploración de muchas zonas de América Central y el Caribe, enfrentaron a los científicos de los países avanzados con nuevas enfermedades y la necesidad de laboratorios donde estudiarlas. Estas circunstancias dieron origen, a comienzos del siglo XX al nacimiento de los Institutos Nacionales de Sanidad en numerosos países, que en España llega hasta hoy con el Carlos III.

    Full Text Available Los médicos y quienes elaboran guías y políticas a veces pasan por alto criterios importantes, les dan un peso indebido o no usan la mejor evidencia disponible para informar sus juicios. Los sistemas explícitos y transparentes para la toma de decisiones pueden ayudar a garantizar que se consideren todos los criterios importantes, y que las decisiones estén basadas en la mejor evidencia disponible. El grupo de trabajo GRADE ha desarrollado marcos «de la evidencia a la decisión» (EtD para los diferentes tipos de recomendaciones o decisiones. El objetivo de los marcos EtD es ayudar a los paneles a usar la evidencia de una manera estructurada y transparente para informar las decisiones respecto de las recomendaciones clínicas, decisiones de cobertura sanitaria y recomendaciones o decisiones sobre el sistema sanitario o sobre salud pública. Los marcos EtD tienen una estructura común: formulación de una pregunta, evaluación de la evidencia y conclusiones. No obstante, existen diferencias entre los marcos para cada tipo de decisión. Los marcos EtD informan a los usuarios sobre los juicios que se han hecho y la evidencia que los apoya dotando de transparencia la base para las decisiones de los que tienen que tomarlas. Los marcos EtD también facilitan la diseminación de las recomendaciones y permiten a los decisores de otros ámbitos adoptar recomendaciones o decisiones, o adaptarlas a su contexto. El siguiente artículo es una traducción del artículo original publicado en British Medical Journal. Los marcos EtD se utilizan actualmente en el marco del Programa de Guías de Práctica Clínica en el Sistema Nacional de Salud, coordinado por GuíaSalud.

    A 10-step total synthesis of the polycyclic polyprenylated acylphloroglucinol (PPAP) natural product hyperforin from 2-methylcyclopent-2-en-1-one is reported. This route was enabled by a diketene annulation reaction and an oxidative ring expansion strategy designed to complement the presumed biosynthesis of this complex meroterpene. The described work enables the preparation of a highly substituted bicyclo[3.3.1]nonane-1,3,5-trione motif in only six steps and thus serves as a platform for the construction of easily synthesized, highly diverse PPAPs modifiable at every position.

    En la microbiología ambiental es de vital importancia contar con un control de la calidad, dentro del cual, debe considerarse el método de ensayo para garantizar una óptima calidad de los datos resultantes. El cálculo de la incertidumbre está siendo abordado por la comunidad de laboratorios y se espera que en un futuro se disponga de directrices más claras en este campo. La incertidumbre, como un atributo cuantificable, es un concepto relativamente nuevo en la historia de las mediciones, a pe...

    Semi-Markov models can be used to analyze the reliability of virtually any fault-tolerant system. However, the process of delineating all of the states and transitions in the model of a complex system can be devastatingly tedious and error-prone. Even with tools such as the Abstract Semi-Markov Specification Interface to the SURE Tool (ASSIST), the user must describe a system by specifying the rules governing the behavior of the system in order to generate the model. With the Table Oriented Translator to the ASSIST Language (TOTAL), the user can specify the components of a typical system and their attributes in the form of a table. The conditions that lead to system failure are also listed in a tabular form. The user can also abstractly specify dependencies with causes and effects. The level of information required is appropriate for system designers with little or no background in the details of reliability calculations. A menu-driven interface guides the user through the system description process, and the program updates the tables as new information is entered. The TOTAL program automatically generates an ASSIST input description to match the system description.

  13. Fortalecimiento de la función rectora de las autoridades sanitarias en las reformas del sector de la salud Strengthening the steering role of health authorities within the context of health sector reform

    Full Text Available El fortalecimiento de la capacidad rectora de las autoridades sanitarias, ahora y en futuras décadas, es asunto de relieve en el contexto de la reforma sectorial. Implica, entre otras cosas, replantear el lugar que ocupa la salud en el contexto de las principales tendencias sociales y económicas observables en el mundo en los albores del nuevo siglo, constituidas fundamentalmente por la redefinición del modelo de desarrollo, la creciente participación en el quehacer sanitario de entidades ajenas al Estado, la transición hacia una democracia participativa en diversos países, la modificación del concepto de lo "público" y lo "privado" y la globalización de la economía. En este nuevo panorama, se impone la necesidad de que el sector sanitario asuma una función distinta: coordinar la movilización de los recursos nacionales, a escala multisectorial, con miras a mejorar la equidad y el bienestar social y focalizar los escasos recursos que existen en los grupos sociales más desprotegidos. La liberalización de la producción y de la distribución de los bienes y servicios de salud, así como la dinámica de mercado que se observa cada vez más en el ámbito de estos servicios y la creciente autonomía de los sistemas de aseguramiento, constituyen nuevos retos para el ejercicio de la autoridad en materia de salud. Adicionalmente, la formación de bloques económicos regionales y el enorme peso ejercido por las grandes compañías multinacionales, con su control del mercado de medicamentos, instrumentos y tecnologías médicas, obligan al sector de la salud a buscar maneras de armonizar la legislación en el ámbito sanitario con las negociaciones de carácter internacional. Y todas estas exigencias superan, al parecer de no pocos expertos, la capacidad de los ministerios de salud de los países latinoamericanos para responder con la debida eficacia, en vista de las limitaciones impuestas en la actualidad por la organización, poder pol

    Full Text Available RESUMO O uso de lodo de esgoto na agricultura se tornou prática corrente em diversos países, sendo atrativa em muitos aspectos, principalmente no fornecimento de matéria orgânica e nutrientes ao solo. Embora os benefícios ambientais e agrícolas do uso de lodo sejam consideráveis, tal prática deve ser realizada de forma sanitariamente segura. Nesse contexto, o objetivo deste estudo foi avaliar a eficiência de um processo de higienização térmica de lodo de esgoto utilizando energia solar. O lodo era aquecido através de um trocador de calor, construído com tubos de cobre e instalado dentro do reator, no qual circula água aquecida em coletores solares planos. Foram realizados 16 ensaios experimentais em diferentes condições de irradiação solar. A inativação térmica da Escherichia coli foi avaliada através do modelo cinético de primeira ordem em condições não isotérmicas. O processo mostrou-se eficiente em ensaios realizados com irradiação solar média do período acima de 500 W.h.m-2, com redução de E. coli entre 4,2 e 7,1 log10 e de coliformes totais entre 4,8 e 7,4 log10. Os ensaios realizados em dias com menores índices de irradiação solar tiveram a eficiência de higienização comprometida, devido às baixas temperaturas atingidas pelo lodo.

  15. Total process surveillance: (TOPS)

    International Nuclear Information System (INIS)

    Millar, J.H.P.

    1992-01-01

    A Total Process Surveillance system is under development which can provide, in real-time, additional process information from a limited number of raw measurement signals. This is achieved by using a robust model based observer to generate estimates of the process' internal states. The observer utilises the analytical reduncancy among a diverse range of transducers and can thus accommodate off-normal conditions which lead to transducer loss or damage. The modular hierarchical structure of the system enables the maximum amount of information to be assimilated from the available instrument signals no matter how diverse. This structure also constitutes a data reduction path thus reducing operator cognitive overload from a large number of varying, and possibly contradictory, raw plant signals. (orig.)

    The Total Quality at Source philosophy is based on optimizing the effectiveness of people in achieving ZERO-DEFECT results. In this paper a philosophy of what, I have come to perceive, it takes to get people to perform to the very best of their abilities and thereby achieve the best results they can, is presented. In the examples I shall describe I have played an instrumental role since it has become my belief that any job can always be done better provided that the people doing it can themselves become convinced that they can do better. Clearly there are many ideas on how to do this. The philosophy that I am presenting in this paper is based on my own experience, where I have both participated and observed it being applied; its effectiveness may be judged by the results.

  18. Total ankle joint replacement.

    Science.gov (United States)

    2016-02-01

    Ankle arthritis results in a stiff and painful ankle and can be a major cause of disability. For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications.

    An outline review notes recent work on total lymphoid irradiation (TLI) as a means of preparing patients for grafts and particularly for bone-marrow transplantation. T.L.I. has proved immunosuppressive in rats, mice, dogs, monkeys and baboons; when given before bone-marrow transplantation, engraftment took place without, or with delayed rejection or graft-versus-host disease. Work with mice has indicated that the thymus needs to be included within the irradiation field, since screening of the thymus reduced skin-graft survival from 50 to 18 days, though irradiation of the thymus alone has proved ineffective. A more lasting tolerance has been observed when T.L.I. is followed by an injection of donor bone marrow. 50% of mice treated in this way accepted allogenic skin grafts for more than 100 days, the animals proving to be stable chimeras with 50% of their peripheral blood lymphocytes being of donor origin. Experiments of a similar nature with dogs and baboons were not so successful. (U.K.)

    The total artificial heart (TAH) is a form of mechanical circulatory support in which the patient's native ventricles and valves are explanted and replaced by a pneumatically powered artificial heart. Currently, the TAH is approved for use in end-stage biventricular heart failure as a bridge to heart transplantation. However, with an increasing global burden of cardiovascular disease and congestive heart failure, the number of patients with end-stage heart failure awaiting heart transplantation now far exceeds the number of available hearts. As a result, the use of mechanical circulatory support, including the TAH and left ventricular assist device (LVAD), is growing exponentially. The LVAD is already widely used as destination therapy, and destination therapy for the TAH is under investigation. While most patients requiring mechanical circulatory support are effectively treated with LVADs, there is a subset of patients with concurrent right ventricular failure or major structural barriers to LVAD placement in whom TAH may be more appropriate. The history, indications, surgical implantation, post device management, outcomes, complications, and future direction of the TAH are discussed in this review.

Para ello, se realizó un estudio de caso durante 1982-1986. Se analizó información documental parlamentaria y prensa médica, principales diarios y revistas e informes y prensa de los actores políticos, sociales y sanitarios. La primera versión de LGS presentada por el PSOE propuso un sistema de salud con financiamiento y gestión pública para lograr cobertura universal, atención integral, participación comunitaria y educación sanitaria. Esta propuesta fue sometida a compleja negociación con grupos empresariales, sindicatos, profesionales de salud.

    La Paz River in Andean highlands is heavily polluted with urban run-off and further contaminates agricultural lowlands and downstream waters at the Amazon watershed. Agricultural produce at this region is the main source of vegetables for the major Andean cities of La Paz and El Alto. We conducted a 1 year study, to evaluate microbial quality parameters and occurrence of multiple enteropathogenic bacteria (Enterohemorrhagic E. coli-EHEC, Enteroinvasive E. coli or Shigella-EIEC/Shigella, Enteroaggregative E. coli-EAEC, Enteropathogenic E. coli-EPEC Enterotoxigenic E. coli-ETEC and Salmonella) and its resistance to 11 antibiotics. Four sampling locations were selected: a fresh mountain water reservoir (un-impacted, site 1) and downstream sites receiving wastewater discharges (impacted, sites 2-4). River water (sites 1-4, N = 48), and soil and vegetable samples (site 3, N = 24) were collected during dry (April-September) and rainy seasons (October-March). Throughout the study, thermotolerant coliform density values at impacted sites greatly exceeded the guidelines for recreational and agricultural water uses. Seasonal differences were found for thermotolerant coliform density during dry season in water samples nearby a populated and hospital compound area. In contrast to the un-impacted site, where none of the tested enteropathogens were found, 100 % of surface water, 83 % of soil and 67 % of vegetable samples at impacted sites, were contaminated with at least one enteropathogen, being ETEC and Salmonella the most frequently found. ETEC isolates displayed different patterns of toxin genes among sites. The occurrence of enteropathogens was associated with the thermotolerant coliform density. At impacted sites, multiple enteropathogens were frequently found during rainy season. Among isolated enteropathogens, 50 % were resistant to at least two antibiotics, with resistance to ampicillin, nalidixic acid, trimethoprim-sulfamethoxazole and tetracycline commonly

Metodología: Se utilizó la metodología de evaluación BIOGAVAL propuesta por el Gabinete de Seguridad e Higiene en el Trabajo de Valencia para la evaluación del riesgo biológico existente en los puestos de técnico de animalario y veterinario. El método seleccionado requiere, para la determinación del nivel de riesgo, la identificación de los microorganismos involucrados, el daño a la salud, las vías de transmisión, la posibilidad de vacunación y el porcentaje de personal vacunado o las medidas higiénicas existentes en el momento de llevar a cabo la evaluación. Resultados: Los resultados de la evaluación de los puestos de trabajo indican la necesidad de medidas preventivas, en especial encaminadas al control de Leptospira y Brucella. Una vez adoptadas las medidas de prevención se observa que el nivel de riesgo de todos los agentes se sitúa en valores inferiores a los límites de exposición biológica establecidos por el método. Se constata la falta de datos determinantes para la valoración numérica del riesgo relativo a algunos agentes identificados. Se considera que los niveles de riesgo emanados del método pueden ser superiores a los reales al no contabilizarse en el "Formulario de medidas higiénicas adoptadas" aquellas medidas realizadas sobre los propios animales. Conclusiones: La metodología de evaluación prueba ser un método ágil, ordenado y relativamente sencillo para la determinación del riesgo biológico al que están expuestos los trabajadores.

    ón internacional ha sostenido que el fortalecimiento de la capacidad de investigación es una de las formas más poderosas, eficientes y sostenibles de hacer progresar la salud y el desarrollo. Sin embargo, los esfuerzos mundiales para promover la investigación en los países en desarrollo han sido guiados sobre todo por la política y, en gran parte, por iniciativa de organismos donantes de los países desarrollados. Aunque esencial, este enfoque político es complementario de y al mismo tiempo contrasta con el de los gestores de la investigación, que deben fortalecerla "sobre el terreno", en servicios de salud que varían mucho según el país, y con mandatos, recursos y limitaciones muy diferentes. El concepto de investigación de las organizaciones sanitarias es amplio y las prácticas son muy variables. Sin embargo, la formación de la capacidad de investigación no es muy diferente de la formación de otros tipos de capacidad organizativa y tiene dos grandes aspectos: el estratégico y el operativo. En las organizaciones del campo de la salud, la creación de una capacidad de investigación importante se hace mucho más difícil cuando no se menciona la investigación en el enunciado de su misión.

La reflexión y el análisis se concretan en la relevancia que tuvieron las relaciones de género y las mujeres en el discurso y la práctica médico-sanitaria en el espacio colonial, y viceversa: cómo la sanidad colonial intervino en la configuración de las relaciones de género; también se constituye en una cuestión central la manera en que resultaron esenciales estas relaciones que, implícita o explícitamente, formaron parte de las actuaciones sanitarias para establecer una distinción clara entre 'nosotros' y 'ellos', para establecer identidades y relaciones que no fueron sólo de género, permitiendo el ejercicio del poder colonial, a la vez que posibilitaron complicidades entre determinados grupos de colonizados y colonizadores.Approaching from a perspective that takes discourse as a tool of power in arranging and shaping the 'social body,' the article shows the importance of looking at gender when addressing the issues of coloniality and the colonial difference in general and when addressing the issue of the Spanish Protectorate of Morocco in particular. This reflection and analysis concentrates on the relevance of gender relations, and of women, in the medical-sanitary discourse and practices of the colonial period. Some central points include how health influenced the shaping of gender relations under colonialism and how these gender relations were implicitly or explicitly part of sanitary initiatives, serving to establish a distinction between 'us' and 'them.' The author also underscores that these relations were not only of gender, and that they enabled colonial power to be exercised

    In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. The close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation.

    Plant phenolics and flavonoids have a powerful biological activity, which outlines the necessity of their determination. The phenolics and flavonoids content of 20 medicinal plants were determined in the present investigation. The phenolic content was determined by using Folin-Ciocalteu assay. The total flavonoids were measured spectrophotometrically by using the aluminium chloride colorimetric assay. The results showed that the family Mimosaceae is the richest source of phenolics, (Acacia nilotica: 80.63 mg gallic acid equivalents, Acacia catechu 78.12 mg gallic acid equivalents, Albizia lebbeck 66.23 mg gallic acid equivalents). The highest total flavonoid content was revealed in Senna tora which belongs to the family Caesalpiniaceae. The present study also shows the ratio of flavonoids to the phenolics in each sample for their specificity.

  16. MODIFIED TECHNIQUE OF TOTAL LARYNGECTOMY

    2010-12-01

    Full Text Available Surgical technique of total laryngectomy is well presented in many surgical textbooks. Essentially, it has remained the same since Gluck an Soerensen in 1922 described all its details. Generally, it stresses the U shape skin incision with releasing laryngeal structures and removing larynx from up to down. Further, pharyngeal reconstruction is performed with different kinds of sutures in two or more layers and is finished with skin suture and suction drainage. One of worst complications following this surgery is pharyngocutaneous fistula (PF. Modifications proposed in this this article suggests vertical skin incision with larynx removal from below upwards. In pharyngeal reconstruction we used the running locked suture in submucosal plan with „tobacco sac“ at the end on the tongue base instead of traditional T shaped suture. Suction drains were not used.The aim of study was to present the modified surgical technique of total laryingectomy and its impact on hospital stay duration and pharyngocutanous fistula formation. In this randomized study we analyzed 49 patients operated with modified surgical technique compared to 49 patient operated with traditional surgical technique of total laryngectomy. The modified technique of total laryngectomy was presented. Using modified technique we managed to decrease the PF percentage from previous 20,41% to acceptable 8,16% (p=0,0334. Also, the average hospital stay was shortened from 14,96 to 10,63 days (t =-2.9850; p=0.0358.The modified technique of total laryngectomy is safe, short and efficient surgical intervention which decreases the number of pharyngocutaneos fistulas and shortens the hospital stay.

  17. Economic total maximum daily load for watershed-based pollutant trading.

    Science.gov (United States)

    Zaidi, A Z; deMonsabert, S M

    2015-04-01

    Water quality trading (WQT) is supported by the US Environmental Protection Agency (USEPA) under the framework of its total maximum daily load (TMDL) program. An innovative approach is presented in this paper that proposes post-TMDL trade by calculating pollutant rights for each pollutant source within a watershed. Several water quality trading programs are currently operating in the USA with an objective to achieve overall pollutant reduction impacts that are equivalent or better than TMDL scenarios. These programs use trading ratios for establishing water quality equivalence among pollutant reductions. The inbuilt uncertainty in modeling the effects of pollutants in a watershed from both the point and nonpoint sources on receiving waterbodies makes WQT very difficult. A higher trading ratio carries with it increased mitigation costs, but cannot ensure the attainment of the required water quality with certainty. The selection of an applicable trading ratio, therefore, is not a simple process. The proposed approach uses an Economic TMDL optimization model that determines an economic pollutant reduction scenario that can be compared with actual TMDL allocations to calculate selling/purchasing rights for each contributing source. The methodology is presented using the established TMDLs for the bacteria (fecal coliform) impaired Muddy Creek subwatershed WAR1 in Rockingham County, Virginia, USA. Case study results show that an environmentally and economically superior trading scenario can be realized by using Economic TMDL model or any similar model that considers the cost of TMDL allocations.

    Full Text Available Intrathoracic hernias after total gastrectomy are rare. We report the case of a 78-year-old man who underwent total gastrectomy with antecolic Roux-Y reconstruction for residual gastric cancer. He had alcoholic liver cirrhosis and received radical laparoscopic proximal gastrectomy for gastric cancer 3 years ago. Early gastric cancer in the remnant stomach was found by routine upper gastrointestinal endoscopy. We initially performed endoscopic submucosal dissection, but the vertical margin was positive in a pathological result. We performed total gastrectomy with antecolic Roux-Y reconstruction by laparotomy. For adhesion of the esophageal hiatus, the left chest was connected with the abdominal cavity. A pleural defect was not repaired. Two days after the operation, the patient was suspected of having intrathoracic hernia by chest X-rays. Computed tomography showed that the transverse colon and Roux limb were incarcerated in the left thoracic cavity. He was diagnosed with intrathoracic hernia, and emergency reduction and repair were performed. Operative findings showed that the Roux limb and transverse colon were incarcerated in the thoracic cavity. After reduction, the orifice of the hernia was closed by suturing the crus of the diaphragm with the ligament of the jejunum and omentum. After the second operation, he experienced anastomotic leakage and left pyothorax. Anastomotic leakage was improved with conservative therapy and he was discharged 76 days after the second operation.

  2. NIF total neutron yield diagnostic

    Cooper, Gary W.; Ruiz, Carlos L.

    2001-01-01

    We have designed a total neutron yield diagnostic for the National Ignition Facility (NIF) which is based on the activation of In and Cu samples. The particular approach that we have chosen is one in which we calibrate the entire counting system and which we call the ''F factor'' method. In this method, In and/or Cu samples are exposed to known sources of DD and DT neutrons. The activated samples are then counted with an appropriate system: a high purity Ge detector for In and a NaI coincidence system for Cu. We can then calculate a calibration factor, which relates measured activity to total neutron yield. The advantage of this approach is that specific knowledge of such quantities as cross sections and detector efficiencies is not needed. Unless the actual scattering environment of the NIF can be mocked up in the calibration experiment, the F factor will have to be modified using the results of a numerical simulation of the NIF scattering environment. In this article, the calibration factor methodology will be discussed and experimental results for the calibration factors will be presented. Total NIF neutron yields of 10 9 --10 19 can be measured with this method assuming a 50 cm stand-off distance can be employed for the lower yields

    Full Text Available The paper is devoted to testing electrooptical distance measuring devices (EDM built in total stations, than can be used for various tasks in the contemporary geodetic works. A rich market offer and availability of these universal measuring systems with satisfying distance range, excellent accuracy and other parameters, make total stations as dominant terrestrial geodetic instruments.For succesfully applying these instruments, above all for relliable distance measurements, the stability of the modulation frequency is the most important pre-condition. In the article, therefore, there are given some methods to verify the modulation frequency stability. In addition, some ways for determining the EDM distance constant and periodical corrections of the phase measuring unit are introduced for 4 types of EDM : LEICA 1700L, TOPCON GTS6A, TOPCON GTS2, C.ZEISS ELTA50. It were also investigated their possibilities for precise distance survey. Values of the determined constants and periodical corrections are presented in Tab. 2.Based on the investigation results of the 4 EDM types and using the values m obtained for different distances S, equations of the a posteriori standard deviations in form : m = (a+b.S were derived too.

    Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost P flows must be recovered and reused, alongside improvements in P-use efficiency. While this motivation is increasingly being recognized, little P recovery is practiced today, as recovered P generally cannot compete with the relatively low cost of mined P. Therefore, P is often captured to prevent its release into the environment without beneficial recovery and reuse. However, additional incentives for P recovery emerge when accounting for the total value of P recovery. This article provides a comprehensive overview of the range of benefits of recovering P from waste streams, i.e., the total value of recovering P. This approach accounts for P products, as well as other assets that are associated with P and can be recovered in parallel, such as energy, nitrogen, metals and minerals, and water. Additionally, P recovery provides valuable services to society and the environment by protecting and improving environmental quality, enhancing efficiency of waste treatment facilities, and improving food security and social equity. The needs to make P recovery a reality are also discussed, including business models, bottlenecks, and policy and education strategies.

    Full Text Available OBJECTIVE: To describe the methodology used to measure and explain income-related inequalities in health and health care utilization over time in selected Latin American and Caribbean countries. METHODS: Data from nationally representative household surveys in Brazil, Chile, Colombia, Jamaica, Mexico, and Peru were used to analyze income-related inequalities in health status and health care utilization. Health was measured by self-reported health status, physical limitations, and chronic illness when available. Hospitalization, physician, dentist, preventive, curative, and preventive visits were proxies for health care utilization. Household income was a proxy for socioeconomic status except in Peru, which used household expenditures. Concentration indices were calculated before and after standardization for all dependent variables. Standardized concentration indices are also referred to as horizontal inequity index. Decomposition analysis was used to identify the main determinants of inequality in health care utilization. RESULTS: Results of analysis of the evolution of income-related inequality in health and health care utilization in Brazil, Chile, Colombia, Jamaica, Mexico, and Peru are presented in separate articles in this issue. CONCLUSIONS: The methodology used for analysis of equity in all six country research studies attempts not to determine causality but to describe and explain income-related inequalities in health status and health care utilization over time. While this methodology is robust, it is not free of errors. When possible, errors have been identified and corrected.OBJETIVO: Describir la metodología usada para medir y explicar la evolución de las desigualdades en la salud y la utilización de la atención sanitaria relacionadas con los ingresos en países seleccionados de América Latina y el Caribe.

    Fecal coliforms concentration and load, and flow of four ditches (Burlamacca, Abate, Motrone, Fiumetto) with mouth into Versilia coast have been studied. Superficial water environmental impact on surrounding sea-water (according to DPR 470/82) has been evaluated. During the study period (from April to September) these mouths behave like lagoons, showing negative positive or no flow, in relation both to the sea and to affluent waters hydrodynamic force. Positive correlation between mm of rain fallen during the week before the drawing and the number of FC/100 ml of ditches water has been pointed out, while there is no correlation with FC/100 ml of sea-water. Sea-water pollution is influenced by ditches flow a nd load of FC s{sup -1}; these two parameters are not correlated to rain, because it is often associated with sea-land wind. Fiumetto ditch is an exception, with its significant correlation index (r = 0.64). The correlation between the number of FC s{sup -1} of the ditches and the number of FC/100 ml of littoral water is significant for Burlamacca and Abate ditches (r > 0.63, p < 0.05). Burlamacca ditch produces greater fecal pollution (FC s{sup -1} = 247077332) than Motrone (FC {sup -1} = 5406436), Abate (FCs{sup -1} = 4114183) and Fiumetto (FCs{sup -1} 2201103) ditches.

    Full Text Available Water quality testing (in situ and in laboratory was conducted on 50 wells across the state of Campeche. Further to this (to aid in water quality management and policy, a GIS was implemented to i approximate Zones of Contribution (ZOC for well recharge which in turn supplies water for main cities in the state and ii perform predictive land change modeling on these ZOC’s to predict the future effect of non-point source pollution. Due to natural geohydrological conditions, values of TDS, pH, and SO4 exceeded Mexican regulations in roughly one third of the wells. Although most wells do not exceed the permissible limits of nutrients and heavy metals, some wells show worryingly high levels of NO2-, TP, and Pb, indicators of pollution from anthropogenic sources. All wells were contaminated by coliform bacteria. Poor water quality in some of the main water sources in the state is mainly due to the proliferation of open dumps and the lack of sewage infrastructure, as well as the ongoing conversion of vegetated land to agriculture into the ZOC’s. It is shown that unless remedial measures are implemented, human activities will continue to extend into these areas, placing the state’s water supply at even higher risk of contamination.Â

  13. Total employment effect of biofuels

    1998-08-01

    The study examined the total employment effect of both direct production of biofuel and energy conversion to heat and electricity, as well as the indirect employment effect arising from investments and other activities in conjunction with the production organization. A secondary effect depending on the increased capital flow is also included in the final result. The scenarios are based on two periods, 1993-2005 and 2005-2020. In the present study, the different fuels and the different applications have been analyzed individually with regard to direct and indirect employment within each separate sector. The greatest employment effect in the production chain is shown for logging residues with 290 full-time jobs/TWh, whereas other biofuels range between 80 and 280 full-time jobs/TWh. In the processing chain, the corresponding range is 200-300 full-time jobs per each additional TWh. Additionally and finally, there are secondary effects that give a total of 650 full-time jobs/TWh. Together with the predicted increase, this suggests that unprocessed fuel will provide an additional 16 000 annual full-time jobs, and that fuel processing will contribute with a further 5 000 full-time jobs. The energy production from the fuels will provide an additional 13 000 full-time jobs. The total figure of 34 000 annual full-time jobs must then be reduced by about 4000 on account of lost jobs, mainly in the oil sector and to some extent in imports of biofuel. In addition, the anticipated increase in capital turnover that occurs within the biofuel sector, will increase full-time jobs up to year 2020. Finally, a discussion is given of the accomplishment of the programmes anticipated by the scenario, where it is noted that processing of biofuel to wafers, pellets or powder places major demands on access to raw material of good quality and that agrarian fuels must be given priority if they are to enter the system sufficiently fast. Straw is already a resource but is still not accepted by

  14. Conversion total hip arthroplasty: Primary or revision total hip arthroplasty

    2015-01-01

    Total hip arthroplasty (THA) is an increasingly common procedure among elderly individuals. Although conversion THA is currently bundled in a diagnosis related group (DRG) with primary THA, there is a lack of literature supporting this classification and it has yet to be identified whether conversion THA better resembles primary or revision THA. This editorial analyzed the intraoperative and postoperative factors and functional outcomes following conversion THA, primary THA, and revision THA to understand whether the characteristics of conversion THA resemble one procedure or the other, or are possibly somewhere in between. The analysis revealed that conversion THA requires more resources both intraoperatively and postoperatively than primary THA. Furthermore, patients undergoing conversion THA present with poorer functional outcomes in the long run. Patients undergoing conversion THA better resemble revision THA patients than primary THA patients. As such, patients undergoing conversion THA should not be likened to patients undergoing primary THA when determining risk stratification and reimbursement rates. Conversion THA procedures should be planned accordingly with proper anticipation of the greater needs both in the operating room, and for in-patient and follow-up care. We suggest that conversion THA be reclassified in the same DRG with revision THA as opposed to primary THA as a step towards better allocation of healthcare resources for conversion hip arthroplasties.

    Instability following total hip arthroplasty (THA) is an unfortunately frequent and serious problem that requires thorough evaluation and preoperative planning before surgical intervention. Prevention through optimal index surgery is of great importance, as the management of an unstable THA is challenging even for an experienced joints surgeon. However, even after well-planned surgery, a significant incidence of recurrent instability still exists. Non-operative management is often successful if the components are well-fixed and correctly positioned in the absence of neurocognitive disorders. If conservative management fails, surgical options include revision of malpositioned components; exchange of modular components such as the femoral head and acetabular liner; bipolar arthroplasty; tripolar arthroplasty; use of a larger femoral head; use of a constrained liner; soft tissue reinforcement and advancement of the greater trochanter.

    2002-01-01

    In nuclear organizations, quality and safety are inextricably linked. Therefore, the search for excellence means reaching excellence in nuclear safety. The International Atomic Energy Agency, IAEA, developed, after the Chernobyl accident, the organizational approach for improving nuclear safety based on the safety culture, which requires a framework necessary to provide modifications in personnel attitudes and behaviors in situations related to safety. This work presents a Total Safety Management Model, based on the Model of Excellence of the Brazilian Quality Award and on the safety culture approach, which represents an alternative to this framework. The Model is currently under validation at the Nuclear Engineering Institute, in Rio de Janeiro, Brazil, and the results of its initial safety culture self assessment are also presented and discussed.

    This bibliographical note presents a book, in which the authors make a plea for a total nuclear disarmament. They think that humanity cannot be found in competition, but in emulation, and examine how we can get rid of the nuclear bomb. They discuss the background of nuclear energy, state that nuclear weapons have always been useless and extremely dangerous, consider arms race as crazy and as a crime against humanity, recall that nuclear weapons already made numerous victims (Hiroshima, Nagasaki, nuclear tests), that they are a sword of Damocles over 7 billions human beings, that nuclear winter would be an apocalypse, that the Non Proliferation Treaty is a decoy. They discuss the political role of nuclear weapons, and outline that the only solution is their abolition. They discuss what has already been done and what is still to be done, and formulate a strategy for the future

    This communication describes a concise and efficient total synthesis of mycalamide A by the convergent coupling of pederic acid unit with the mycalamine unit. The left-half, (+)-7-benzoylpederic acid, was synthesized from (2R,3R)-3-methylpent-4-en-2-ol in seven steps and 34.6% overall yield through a route that features a one-step Pd(II)-catalyzed tandem Wacker/Heck cyclization reaction to prepare the tetrahydropyran ring system. The right-half, the mycalamine unit, was synthesized in 21 steps and 10.5% overall yield from diethyl d-tartrate. Effective, stereoselective methods were developed for the assembly of the two parts to yield either mycalamide A or C(10)-epi-mycalamide A.

    1993-12-01

    These Guidelines were designed by the Energy Quality Council to help managers and supervisors in the Department of Energy Complex bring Total Quality Management to their organizations. Because the Department is composed of a rich mixture of diverse organizations, each with its own distinctive culture and quality history, these Guidelines are intended to be adapted by users to meet the particular needs of their organizations. For example, for organizations that are well along on their quality journeys and may already have achieved quality results, these Guidelines will provide a consistent methodology and terminology reference to foster their alignment with the overall Energy quality initiative. For organizations that are just beginning their quality journeys, these Guidelines will serve as a startup manual on quality principles applied in the Energy context.

    As government funding grows scarce, competition between the national laboratories is increasing dramatically. In this era of tougher competition, there is no for resistance to change. There must instead be a uniform commitment to improving the overall quality of our products (research and technology) and an increased focus on our customers` needs. There has been an ongoing effort to bring the principles of total quality management (TQM) to all Energy Systems employees to help them better prepare for future changes while responding to the pressures on federal budgets. The need exists for instituting a vigorous program of education and training to an understanding of the techniques needed to improve and initiate a change in organizational culture. The TQM facilitator is responsible for educating the work force on the benefits of self-managed work teams, designing a program of instruction for implementation, and thus getting TQM off the ground at the worker and first-line supervisory levels so that the benefits can flow back up. This program plan presents a conceptual model for TQM in the form of a hot air balloon. In this model, there are numerous factors which can individually and collectively impede the progress of TQM within the division and the Laboratory. When these factors are addressed and corrected, the benefits of TQM become more visible. As this occurs, it is hoped that workers and management alike will grasp the ``total quality`` concept as an acceptable agent for change and continual improvement. TQM can then rise to the occasion and take its rightful place as an integral and valid step in the Laboratory`s formula for survival.

    Background Knee prosthesis instability (KPI) is a frequent cause of failure of total knee arthroplasty. Moreover, the degree of constraint required to achieve immediate and long-term stability in total knee arthroplasty (TKA) is frequently debated. Questions This review aims to define the problem, analyze risk factors, and review strategies for prevention and treatment of KPI. Methods A PubMed (MEDLINE) search of the years 2000 to 2010 was performed using two key words: TKA and instability. One hundred and sixty-five initial articles were identified. The most important (17) articles as judged by the author were selected for this review. The main criteria for selection were that the articles addressed and provided solutions to the diagnosis and treatment of KPI. Results Patient-related risk factors predisposing to post-operative instability include deformity requiring a large surgical correction and aggressive ligament release, general or regional neuromuscular pathology, and hip or foot deformities. KPI can be prevented in most cases with appropriate selection of implants and good surgical technique. When ligament instability is anticipated post-operatively, the need for implants with a greater degree of constraint should be anticipated. In patients without significant varus or valgus malalignment and without significant flexion contracture, the posterior cruciate ligament (PCL) can be retained. However, the PCL should be sacrificed when deformity exists particularly in patients with rheumatoid arthritis, previous patellectomy, previous high tibial osteotomy or distal femoral osteotomy, and posttraumatic osteoarthritis with disruption of the PCL. In most cases, KPI requires revision surgery. Successful outcomes can only be obtained if the cause of KPI is identified and addressed. Conclusions Instability following TKA is a common cause of the need for revision. Typically, knees with deformity, rheumatoid arthritis, previous patellectomy or high tibial osteotomy, and

    Foodborne disease (FBD) is a global public health concern, and foods from animal sources have been associated with outbreaks of food-related illness. In this study, animal carcasses from the two abattoirs (HT1 and HT2) in the formal meat sector (FMS) and slaughter points in the informal meat sector (INMS) were examined at two stages of slaughter (before washing and after washing) for aerobic colony counts (ACC) and total viable count (TCC), as well as Escherichia coli and Staphylococcus aureus count. At each stage, carcasses were sampled by swabbing at the neck, brisket, flank, and rump. ACC for beef, mutton, and pork carcasses at HT1 and HT2 before washing were between 2.5⁻5.8, 2.2⁻4.7, and 2.7⁻3.7 mean log CFU/cm², respectively, and TCC count before washing was highest on the neck of cattle (6.3 ± 2.4) and after washing was highest on the perineal of sheep (5.7 ± 6.9). In the INMS, TCC count was highest on the brisket (6.9 ± 3.2) and in the neck (5.5 ± 2.4). Higher ACC values of 6.2⁻6.7 mean log CFU/cm² were obtained in the INMS. The highest count for E. coli (4.2 mean log CFU/cm²) after washing was in the neck, while the highest count for S. aureus (4.0 mean log CFU/cm²) was in the flank. All bacteria count in the INMS exceeded acceptable limits, and washing did not significantly reduce microbial load in meat in the FMS and INMS. Bacteria count in the FMS and INMS exceeded acceptable standards. However, meat processed in the INMS poses a more significant risk of FBD to consumers.

    The consumption of crops fertilized with human waste represents a potential route of exposure to antibiotic-resistant fecal bacteria. The present study evaluated the abundance of bacteria and antibiotic resistance genes by using both culture-dependent and molecular methods. Various vegetables (lettuce, carrots, radish, and tomatoes) were sown into field plots fertilized inorganically or with class B biosolids or untreated municipal sewage sludge and harvested when of marketable quality. Analysis of viable pathogenic bacteria or antibiotic-resistant coliform bacteria by plate counts did not reveal significant treatment effects of fertilization with class B biosolids or untreated sewage sludge on the vegetables. Numerous targeted genes associated with antibiotic resistance and mobile genetic elements were detected by PCR in soil and on vegetables at harvest from plots that received no organic amendment. However, in the season of application, vegetables harvested from plots treated with either material carried gene targets not detected in the absence of amendment. Several gene targets evaluated by using quantitative PCR (qPCR) were considerably more abundant on vegetables harvested from sewage sludge-treated plots than on vegetables from control plots in the season of application, whereas vegetables harvested the following year revealed no treatment effect. Overall, the results of the present study suggest that producing vegetable crops in ground fertilized with human waste without appropriate delay or pretreatment will result in an additional burden of antibiotic resistance genes on harvested crops. Managing human exposure to antibiotic resistance genes carried in human waste must be undertaken through judicious agricultural practice. Copyright © 2014, American Society for Microbiology.

    Full Text Available Objectives: we analyzed the characteristics of patients with gastric tumors diagnosed with multiple malignant primary neoplasm (MMPN in the Health District of León. Material and methods: using the information in the Tumor Registry at León Hospital patients selected were those with gastric neoplasms diagnosed between 1993 and 2002. A follow-up was performed until December 31, 2004, and the characteristics of patients diagnosed with a second neoplasm were analyzed. Results: MMPN prevalence was 1,96%; 56% of patients had a history of cancer in first-degree relatives. The most frequent second neoplasms were digestive (26% and urologic (21%; 87% of patients were diagnosed with a second neoplasm within the first two years. No significative differences in survival were observed among patients with synchronous or metachronous MMPN. Conclusions: MMPN in patients with gastric neoplasms is a relevant problem. While external carcinogenic agents could act as promoters in the development of second neoplasms, these patients seem to have a genetic background favoring the development of MMPN. Secondary prevention is the best measure to avoid MMPN development.Objetivos: analizar las características de los pacientes con tumores gástricos diagnosticados de una neoplasia primaria maligna múltiple (NPMM en el área sanitaria de León. Pacientes y método: utilizando los datos del Registro de Tumores del Hospital de León se han seleccionado aquellos pacientes con tumores gástricos diagnosticados entre 1993 y 2002. Se realizó un seguimiento hasta el 31 de diciembre de 2004 analizando las características de los pacientes diagnosticados de una segunda neoplasia durante el periodo de seguimiento. Resultados: la prevalencia de NPMM fue del 1,96%. El 56% de los pacientes tenían antecedentes oncológicos en familiares de primer grado. Las segundas neoplasias más frecuentes fueron las digestivas (26% y las urológicas (21%. El 87% de los pacientes fueron

    Full Text Available Objetivo: Evaluar el impacto de la Ley 28/2005 de medidas sanitarias frente al tabaquismo en la prevalencia de la exposición al humo ambiental del tabaco (HAT en Barcelona. Métodos: Estudio de evaluación antes-después mediante comparación de dos encuestas transversales. Las fuentes de datos fueron las Encuestas de Salud de Barcelona de 2000 y 2006. Se analizó la prevalencia de exposición al HAT en población adulta no fumadora según el ámbito de exposición (hogar, trabajo y tiempo libre y las variables sociodemográficas. Resultados: La exposición al HAT en no fumadores en el hogar y el trabajo disminuyó significativamente (p Objective: To assess the impact of the 28/2005 Spanish smoking law on exposure to second-hand smoke (SHS in Barcelona. Methods: We performed a pre-post evaluation study. Two cross-sectional surveys were compared. Data were obtained from the Barcelona Health Surveys of 2000 and 2006. The prevalence of SHS exposure among non-smoking adults was analyzed by setting (home, workplace and leisure time and sociodemographic variables. Results: SHS exposure in non-smokers significantly decreased between 2000 and 2006 (p <0.01. Odds ratios adjusted by sex, age and social class were 0.7 (95% CI: 0.6-0.8 for home and 0.2 (95% CI: 0.2-0.3 for workplace exposure in 2006 compared with 2000. In both settings, the decrease in exposure was greater in the higher social classes. After the implementation of the law, almost 50% of the population remained exposed to SHS during leisure time, younger people being the most exposed (83.5%. Conclusion: After the implementation of the law, the prevalence of SHS exposure in non-smokers in Barcelona decreased significantly in workplaces and in the home. Nevertheless, nearly half of the population remained exposed to SHS during leisure time.

    Full Text Available Fundamentos: Las carencias en la colaboración entre Atención Primaria (AP y Salud Mental (SM constituyen un problema relevante en la atención a los pacientes con depresión. Resulta necesario analizar y evaluar los modelos de colaboración existentes para valorar su aplicabilidad en el sistema de salud español. El objetivo del presente estudio es conocer las principales características de los distintos modelos de colaboración AP-SM en la atención a los pacientes diagnosticados de depresión y la calidad de la evidencia científica acerca de su efectividad. Métodos: Meta-revisión sistemática de los estudios secundarios publicados entre 2001 y 2010 en MEDLINE, PsycINFO, Embase, LILACS, IBECS, IME y la Biblioteca Cochrane. Las revisiones se evaluaron mediante la herramienta AMSTAR. Se realizó una síntesis aproximativa de la calidad de las evidencias encontradas. Resultados: Se evaluaron 69 estudios. La variabilidad según contextos y las carencias metodológicas condicionan que la calidad de las evidencias sea en general baja o dudosa. Las estrategias más efectivas integran intervenciones de responsabilización en el seguimiento de los pacientes, rediseños en la gestión, e información y comunicación compartidas. Las meta-revisiones de estudios secundarios sobre modelos colaborativos favorecen la accesibilidad a las evidencias publicadas, pero conllevan importantes retos metodológicos. Conclusiones: La calidad de la evidencia sobre la efectividad de los modelos de colaboración AP-SM durante la atención sanitaria a las personas con depresión es predominantemente baja o dudosa y su significado y aplicabilidad son menores cuanto más se simplifica el análisis de sus componentes, procesos y circunstancias de implementación.

MÉTODOS: Comparamos los nuevos casos de sida durante dos períodos de tres años, 1992-1994 y 1998-2000, en cuatro poblaciones: 1 todos los Estados Unidos, 2 Puerto Rico, 3 la Región de Salud de Bayamón (que se sitúa en la parte norte del centro de Puerto Rico y contiene 11 de las 78 municipalidades de la isla y una cohorte de pacientes infectados por el VIH y atendidos en la Escuela de Medicina de la Universidad Central del Caribe (UCC. La UCC está en Bayamón, Puerto Rico, dentro de un complejo médico universitario donde se encuentran el hospital escuela (Hospital Universitario Ramón Ruíz Arnaú, las clínicas ambulatorias (Clínicas de Inmunología para pacientes infectados por el VIH y los edificios administrativos. Todo ello en conjunto representa la principal infraestructura de atención sanitaria de carácter público en la Región de Salud de Bayamón. RESULTADOS: La frecuencia de nuevos casos de sida se redujo notablemente entre los dos períodos en cada una de las cuatro poblaciones estudiadas. La reducción de 48,1% observada en Puerto Rico superó a la de 40,9% observada en los Estados Unidos en general. La reducción en Puerto Rico obedeció probablemente a la mayor disponibilidad y aplicación de la TARGA y a la provisión de atención sanitaria de manera integrada a pacientes de sida o con infección por el VIH en cada clínica ambulatoria regional. A pesar de estas mejoras, sin embargo, el n

    Full Text Available Las hortalizas aportan grandes beneficios para la salud debido a sus innumerables propiedades alimenticias; sin embargo, existe una gran variedad de factores que ponen en riesgo la calidad sanitaria de las mismas constituyéndose en vehículos para enfermedades de transmisión alimentaria (ETA. Por ello, se decidió evaluar la calidad microbiológica y parasitológica de dos hortalizas, lechuga (Lactuca sativa y cilantro (Coriandrum sativum expendidas en la Parroquia Santa Rita del Municipio Francisco Linares Alcántara (Aragua, Venezuela. Se analizaron un total de 20 muestras, 10 de cilantro y 10 de lechuga; la determinación microbiológica se realizó por la técnica del Número Más Probable y el análisis parasitológico, mediante observación directa, tinción de Kinyoun y la técnica de Faust. Los resultados mostraron la presencia de coliformes totales (1,1x104 NMP/g en el 100 % de las muestras. No se evidenció coliformes fecales en ninguna de las muestras. En relación al análisis parasitológico, se identificaron protozoarios intestinales, con mayor prevalencia de Blastocystis spp. y menor en helmintos. Los resultados demuestran el peligro potencial que representa el consumo de hortalizas frescas contaminadas para la salud pública. Se debe concientizar a la población sobre medidas sanitarias preventivas que deben aplicar antes del consumo e implementar medidas de control que mejoren las condiciones higiénicas en la cadena de comercialización.
