A spatial analysis of private well water Escherichia coli contamination in southern Ontario.
Research to date has provided limited insight into the complexity of water-borne pathogen transmission. Private well water supplies have been identified as a significant pathway in infectious disease transmission in both the industrialised and the developing world. Using over 90,000 private well water submission records representing approximately 30,000 unique well locations in south-eastern On...
متن کاملComparison of Escherichia coli, Total Coliform, and Fecal Coliform Populations as Indicators of Wastewater Treatment Efficiency
Escherichia coli, total coliform, and fecal coliform population data were collected from two wastewater treatment facilities, a subsurface flow artificial wetlands, and a receiving stream. Results are presented from individual wastewater treatment process streams, final effluent, and river sites upstream and downstream of the treatment [ acilities. The QuantiTray technique with 4-mcthylumbellif...
متن کاملDevelopment of multiplex PCR for the detection of total coliform bacteria for Escherichia coli and Clostridium perfringens in drinking water.
Multiplex PCR amplification of lacZ, uidA and plc genes was developed for the simultaneous detection of total coliform bacteria for Escherichia coli and Clostridium perfringens, in drinking water. Detection by agarose gel electrophoresis yielded a band of 876 bp for the lacZ gene of all coliform bacteria; a band of 147 bp for the uidA gene and a band of 876 bp for the lacZ gene of all strains o...
متن کاملFaecal coliform, Escherichia coli or what?
The use of indicators for evaluating the microbiological quality of the marine surf-zone water is a worldwide practice. It is important that the indicator used, is the most relevant in relation to bathers’ health. It must be easy to detect and it must be cost effective. This paper reports the comparison between the occurrence of faecal coliforms and Escherichia coli in the marine surf-zone. Bot...
متن کاملComparing Defined- Substrate Coliform Tests for the Detection of Escherichia coli in Water
Two commercially available defined-substrate coliform tests were compared with EC medium plus 4-methylumbelliferyl-p-D-glucuronide (MUG) for detecting chlorine-exposed Escherichia coli in spiked water samples. Statistical analyses of the test results indicated no sign!nifcant differences in detection of E. cofi between the Autoanalysis Colilert test and EC medium with MUG. There were, however, ...
