Bacteroides fragilis HSP40 phages have been detected in waters with various levels of fecal contamination of human origin. The average numbers of B. fragilis phages present in sewage water reached 5.3 x 10(3) per 100 ml of water. We found a number 1,000 times lower in a river contaminated with domestic sewage only, in which the levels of fecal coliforms and fecal streptococci were 10,000 times ...

there are many trends in making an ecological city all around the word, one of important cases in this approach is safe and health water. according by definitions, safe and potable water is water needed for conducting the activities of man. potable water is the most important renewable sources and this resource plays important role for survival of most living organisms as well as man based on s...

Fecal contamination of water bodies causes a public health problem and economic loss. To control such contamination management actions need to be guided by sound science. From 2007-2009 a study was undertaken to determine the sources of fecal bacteria contamination to the marine waters adjoining the Town of Wrightsville Beach, North Carolina, USA. The research effort included sampling for fecal...

Two strains of Vibrio cholerae serotype O1 Inaba were isolated from eastern oysters, Crassostrea virginica, collected from estuarine waters in Florida during April 1980. The oyster meats and waters from which the oysters were collected had low fecal coliform counts, and the area had no prior evidence of sewage contamination.

The risks of contamination of finfish products with active pathogens largely depend on the type of product concerned and disposal methods of the importing country. Frozen fish used as bait or to feed high-value species present the greatest risk as vehicles of contamination because they are unprocessed. Freezing preserves viral- and some bacterial-pathogens, thus the use of such fish as bait can...

Source determination of fecal contamination is imperative to efficiently reduce the fecal material load to environmental waters. This study developed primer pairs targeting three F+ RNA bacteriophages and a simple filtration sampling method to enumerate and identify coliphages in environmental waters. Water samples were collected seasonally for one year from the watershed of Table Rock Lake on ...

Sewage contamination of our ground and surface waters is a major public health concern. Current indicator bacteria, such as Escherichia coli and enterococci, can naturalize in subtropical and tropical environments, ergo better indicator organisms are needed. Furthermore, current indicator bacteria do not discriminate between contamination sources, and hence the application of microbial source t...

Microbial contamination affects a large number of water bodies in the US. Because it is not feasible to directly monitor all pathogens, it is standard practice to monitor fecal indicator bacteria (FIB), such as total and fecal coliforms, Clostridium perfringens, Escherichia coli, and fecal enterococci, in water. Epidemiological studies have established human health standards based on exposure t...
