OBJECTIVE To evaluate the microbiological quality of treated and untreated water samples came from urban and rural communities and to examine the relationship between coliforms occurrence and average water temperature, and a comparison of the rainfall levels. METHODS A sample of 3,073 untreated and treated (chlorinated) water from taps (1,594), reservoir used to store treated water (1,033), s...
An investigation was conducted to evaluate the water quality of some ground for irrigation, drinking and livestock consumption. Fifteen samples were collected from Babugonj upazila of Barisal district in Bangladesh. The chemical constituents of water samples were determined to find out their suitability for irrigation, drinking and Livestock consumption. As per pH all water samples were slightl...
a user-friendly and inexpensive ionic liquid-based single-drop microextraction (il-sdme) method was developed to preconcentrate trace amounts of aminophenol isomers (aps) from human urine, hair dye and water samples prior to analysis by high performance liquid chromatography-ultraviolet spectrophotometry detection (hplc-uv). under optimum conditions (i.e., 3.5 µl of 1-hexyl-3-methylimidazolium ...
a research plan was developed to evaluate the occurrence of enteroviruses, giardia cysts and cryptosporidium oocysts in thirty-five different sites in the city of mashhad, iran. the occurrence of these pathogenic microorganisms was evaluated to investigate a possible health risk in the communities. for the detection of enteroviruses in water samples, the conventional method of cell culture, usi...
Listeria monocytogenes is an important pathogen which causes an infection called listeriosis. Because of the high mortality rate (~30%) associated with listeriosis, and the widespread nature of the organism, it is a major concern for food and water microbiologists since it has been isolated from various types of foods, including seafood, as well as from the aqueous environment. To investigate t...
A cross-sectional study was conducted to assess the bacteriological quality of water in Haldwani block, Nainital District, India. Stratified random sampling was used to categorize water sources and consumer points. In total, 108 samples were collected: 15 from the Gola river, 51 from water taps, 24 from water treatment plants and 18 from tube wells. Samples were tested for coliforms by the most...
Water samples were concentrated by the modified adsorption-elution technique followed by speedVac reconcentration of the filter eluates. Reverse transcriptase-nested polymerase chain reaction (RT-nested PCR) was used to detect rotavirus RNA in concentrates of the water. The detection limit of the rotavirus determined by RT-nested PCR alone was about 1.67 plaque forming units (PFU) per RT-PCR as...
