coli per 100 ml sample (LPR = 1.2, 95% CI 1.1-1.2 for diarrheal disease; LPR = 1.2, 95% CI 1.0-1.3 for dysentery). Unlike the results of some previous studies, diarrheal disease risks did not increase progressively in magnitude with increasing concentration of E. coli in drinking water....
Waterbome diseases are among the leading causes of morbidity and mortality in developing countries and every year around 2.2 million people die due to basic hygiene related diseases like conform diarrhoea. The total 1000 sample from various sources such as tube wells (340), open wells (340) and...
Escherichia coliis an important pathogenic indicator in drinking water. Viable but non-culturable (VBNC)E.coliinduced by low level chlorination was found to have higher antibiotic tolerance. The emerging of VBNC bacteria in drinking water systems is posing challenges to the control of bio-safety. I...
Chelation with Tiron of the Alprior to exposure maintained the in a cultivable state. This phenomenon deserves further investigation in view of the reliance placed on as an indicator of fecal contamination. 展开 关键词: alum, aluminium chelation, drinking water, E. coli cultivation ...
The detection and enumeration of indicator bacteria such as Escherichia coli is used to assess the extent of faecal contamination of drinking water. On the basis of this approach, the effectiveness of storing water contaminated with faecal indicator bacteria in brass or earthern vessels (mutkas) of...
Fast, sensitive, and especially, multianalyte test systems are currently of high interest for the monitoring and quality control of drinking water, since traditional microbiological methods are labor intensive and can take days until a response is achieved. In this study, the first flow-through chem...
At 4 weeks post-infection, all mice were treated with trimethoprim and sulfamethoxazole in the drinking water for 10 d (54 and 270 μg ml−1water, respectively)6. Urine was collected weekly to confirm clearance of bacteriuria. Four weeks after the initiation of antibiotics, naïve...
A process for the preparation of a composition for use for determination of tatal coliforms and faecal coliforms in drinking water The objectives of this study were to present data on the presence of Salmonell a spp. and on the 25 enumeration of Escherichia coli and faecal coliforms re... SM...
mainly influences short-term soil contamination.Dye-off is the dominant process affectingE.coliconcentration in topsoil and leaching water.Persistence models ofE.coliin topsoil and leachate after pollution are log-linear.Less than 1% ofE.coliin irrigation water is transferred through the soil column....
detoxifying enzymes such as reductive dehalogenases23 and oxygenases24, have been exploited in the bioremedia- tion of chlorinated aliphatic hydrocarbons and polycyclic aromatic contaminated soil and groundwater. The E. coli K-12 MG1655 strain used in this study is the primary experimental reference...
