Samples of drinking water from different sources in greater Cairo, Egypt, and bottled drinking water were tested for total coliform, fecal coliform, and coliphage populations. Of the 147 samples tested, 4 samples were positive for both total coliforms and coliphage, 65 samples were negative for total coliforms, fecal coliforms, and coliphage, and 78 samples were positive for coliphage and negat...

Livestock are known contributors to stream pollution. Numbers of fecal streptococci and Escherichia coli in manure naturally deposited by livestock in the field are needed for activities related to bacterial source tracking and determining maximum daily bacterial loading of streams. We measured populations of fecal streptococci and E. coli in fresh and dry manure from cattle (Bos taurus L.), ho...

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...

This study compared recovery of fecal coliform bacteria from sewage by Colilert-18 and Standard Methods 9222D (membrane-Fecal Coliform medium) in accordance with the U.S. Environmental Protection Agency (EPA) Alternative Test Protocol (ATP). Samples were collected from 10 different wastewater treatment plants in the northeastern United States and tested in a single laboratory. Twenty replicates...

The presence of coliform bacteria in water and in or on other foods depends on many environmental factors, each of which must be determined separately for each item of food in question. When a correlation is found to exist between insanitary methods of food production and the presence of Escherichia coti in the finished product, the presence of confirmed fecal strains of coliform organisms can ...

Testing for coliforms has a long history in the dairy industry and has helped to identify raw milk and dairy products that may have been exposed to unsanitary conditions. Coliform standards are included in a number of regulatory documents (e.g., the U.S. Food and Drug Administration's Grade "A" Pasteurized Milk Ordinance). As a consequence, detection above a threshold of members of this method-...

BACKGROUND Water-related diseases are of great concern in developing countries like Nepal. Every year, there are countless morbidity and mortality due to the consumption of unsafe drinking water. Recently, there have been increased uses of bottled drinking water in an assumption that the bottled water is safer than the tap water and its use will help to protect from water-related diseases. So, ...
