CPLOP: The Cal Poly Library of Pyroprints
<p>To date, microbial source tracking (MST), i.e. determining the source of microbial contamination based on the specific strains observed in the environment, often uses methods that are time-consuming, expensive and not always reliable. The biology department at Cal Poly, San Luis Obispo has …

Host Specific Microbial Source Tracking and Quantification Using a Partial 16SrRNA Sequence of Bacteroides on the Finley River, a Tributary of the James River in Southwest Missouri
<p>Microbial source tracking (MST) is a general term given to any process which aims to determine the source of microbial contamination found in an environmental (usually water) sample. These methods include both phenotypic and genotypic strategies. In this study, quantitative PCR was used to …

Identification of fecal pollution sources of karst waters by a combination of Bacteroidales genetic marker, bacterial indicators, and environmental variables
… by a combination of Bacteroidales-based microbial source tracking (MST), traditional bacterial indicators, and environmental variables. Water samples from springs and wells were collected from Illinois, Wisconsin, Kentucky and Missouri quarterly. Quantitative PCR with seven primer sets …

A Comparative Study of Three Bacterial Source Tracking Methods and the Fate of Fecal Indicator Bacteria in Marine Waters and Sediments
… bacteria (FIB) in sand and sediments. The microbial source tracking (MST) methods antibiotic resistance analysis (ARA), Bacteroides human-specific primer test, and fluorometry were compared against the FIBs to determine how reliable each method was in detecting the presence of human fecal …

Development of a 16S rRNA gene sequence as a biomarker specific to the gastrointestinal tract and feces of swine based on suppressive subtractive hybridization
… In recent years there has been a shift towards microbial source tracking (MST). MST employs microbiological, genotypic, phenotypic and chemical methods to determine the source of fecal pollution in water bodies. Previous studies aimed at developing swine fecal biomarkers have had limited …

Improving microbial fate and transport modeling to support TMDL development in an urban watershed
… efforts. Due to limited understanding of microbial fate and transport, predictions of FIB concentrations are associated with considerable uncertainty relative to other water-quality contaminants. By focusing on a data-rich instrumented urban watershed, this study aims to improve …

Evaluation, Development and Improvement of Genotypic, Phenotypic and Chemical Microbial Source Tracking Methods and Application to Fecal Pollution at Virginia's Public Beaches
The microbial source tracking (MST) methods of antibiotic resistance analysis (ARA) and fluorometry (to detect optical brighteners in detergents) were used in the summers of 2004 and 2005 to determine the origins of fecal pollution at beaches with a past history of, or the potential for, high …

Use of Escherichia coli for Microbial Source Tracking in a Mixed Use Watershed in Northern Virginia
… stream were chosen for E. coli monitoring and microbial source tracking (MST). MST was performed using antibiotic resistance analysis (ARA) and fluorometric analysis. Escherichia coli was chosen as the indicator bacterium for purposes of comparison with previous project data and because a large …
