Origin of fecal contamination in waters from contrasted areas: stanols as Microbial Source Tracking markers.
Improving the microbiological quality of coastal and river waters relies on the development of reliable markers that are capable of determining sources of fecal pollution. Recently, a principal component analysis (PCA) method based on six stanol compounds (i.e. 5β-cholestan-3β-ol (coprostanol), 5β-cholestan-3α-ol (epicoprostanol), 24-methyl-5α-cholestan-3β-ol (campestanol), 24-ethyl-5α-cholesta...
متن کاملMICROBIAL SOURCE TRACKING - FAQs
Microbial Source Tracking within your watershed can provide important information regarding the Point Source (structures, pipes, sewage outfalls) and Non-Point Source (runoff, animals) contamination present in your service area. Determination of human, ruminant and other fecal inputs into surface source or ground waters can provide a scientific basis for watershed management decisions and can a...
متن کاملIdentification of Human and Animal Fecal Contamination after Rainfall in the Han River, Korea
We investigated the effect of rainfall on the levels and sources of microbial contamination in the Han River, Korea. Thirty-four samples were collected at two sampling sites located upstream and downstream in the river from July 2010 to February 2011. Various fecal indicator microorganisms, including total coliform, fecal coliform, Escherichia coli, Enterococcus spp., somatic and male-specific ...
متن کاملBasin-wide analysis of the dynamics of fecal contamination and fecal source identification in Tillamook Bay, Oregon.
The objectives of this study were to elucidate spatial and temporal dynamics in source-specific Bacteroidales 16S rRNA genetic marker data across a watershed; to compare these dynamics to fecal indicator counts, general measurements of water quality, and climatic forces; and to identify geographic areas of intense exposure to specific sources of contamination. Samples were collected during a 2-...
متن کاملUse of Bacteroidales microbial source tracking to monitor fecal contamination in fresh produce production.
In recent decades, fresh and minimally processed produce items have been associated with an increasing proportion of food-borne illnesses. Most pathogens associated with fresh produce are enteric (fecal) in origin, and contamination can occur anywhere along the farm-to-fork chain. Microbial source tracking (MST) is a tool developed in the environmental microbiology field to identify and quantif...
