Use of viral pathogens and indicators to differentiate between human and non-human fecal contamination in a microbial source tracking comparison study.
Assays for the detection and typing of adenoviruses, enteroviruses and F+ specific coliphages were performed on samples created as part of a national microbial source tracking methods comparison study. The samples were created blind to the researchers, and were inoculated with a variety of types of fecal contamination source (human, sewage, dog, seagull and cow) and mixtures of sources. Viral t...

متن کاملSemi-quantitative evaluation of fecal contamination potential by human and ruminant sources using multiple lines of evidence.
Protocols for microbial source tracking of fecal contamination generally are able to identify when a source of contamination is present, but thus far have been unable to evaluate what portion of fecal-indicator bacteria (FIB) came from various sources. A mathematical approach to estimate relative amounts of FIB, such as Escherichia coli, from various sources based on the concentration and distr...
متن کاملDetermination of fecal contamination origin in reclaimed water open-air ponds using biochemical fingerprinting of enterococci and fecal coliforms.
Low levels of fecal indicator bacteria (FIB) were recently detected in two reclaimed water open-air ponds used to irrigate a golf course located in Northeastern Spain. The aim of this study was to evaluate the feasibility of a biochemical fingerprinting method to track the origin of fecal contamination in water with low FIB levels, as in the aforementioned ponds. We also aimed to determine whet...
متن کاملMicrobial Source Tracking
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...
