Genotypic analysis of Enterococci isolated from fecal-polluted water from different sources by pulsed-field gel electrophoresis (PFGE) for application to microbial source tracking.
PFGE has potential applications in the source tracking of fecal pollution in aquatic environments. We tried to distinguish the genotypes of Enterococcus faecium collected from fecal-contaminated water using PFGE. Well identified 115 strains of E. faecium were classified into 25 PFGE patterns, and characteristics distinctive to each genotype were recognized. Analysis of the characteristics of ge...
متن کاملHypothesis-Driven Approach for the Identification of Fecal Pollution Sources in Water Resources
Water resource management must strive to link catchment information with water quality monitoring. The present study attempted this for the field of microbial fecal source tracking (MST). A fecal pollution source profile based on catchment data (e.g., prevalence of fecal sources) was used to formulate a hypothesis about the dominant sources of pollution in an Austrian mountainous karst spring c...
متن کاملA Proposal for Source Tracking of Fecal Pollution in Recreational Waters by Pulsed-Field Gel Electrophoresis
This study aimed to identify specific river sources of fecal contamination by applying pulsed-field gel electrophoresis (PFGE) to environmental water samples from a recreational beach in Japan. The genotypes of all Enterococcus faecium and Enterococcus faecalis strains used as indicators of fecal pollution on the recreational beach and rivers were analyzed by PFGE, and the PFGE profiles of the ...
متن کاملOrigin 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 کاملApplication of an integrated community analysis approach for microbial source tracking in a coastal creek.
High fecal indicator bacterial (FIB) concentrations signal urban coastal water quality impairments that can threaten public health. However, FIB (total and fecal coliform plus Enterococcus sp.) concentrations are not specific to human waste, and thus, microbial source tracking (MST) is employed to assess public health risks and remediation alternatives. Currently, water quality diagnosis requir...
