Rapid QPCR-based assay for fecal Bacteroides spp. as a tool for assessing fecal contamination in recreational waters.
Concentrations of fecal indicator bacteria (FIB; e.g. Escherichia coli, and Enterococcus sp.) can only be used in limited ways for determining the source of fecal contamination in recreational waters because they cannot distinguish human from non-human fecal contamination. Several Bacteroides spp. have been suggested as potential alternative indicators. We have developed a rapid, culture-indepe...
متن کاملCulture-based indicators of fecal contamination and molecular microbial indicators rarely correlate with Campylobacter spp. in recreational waters.
Campylobacter spp. are the leading cause of gastroenteritis worldwide. Most human infections result from contaminated food; however, infections are also caused by recreational waterway contamination. Campylobacter culture is technically challenging and enumeration by culture-based methods is onerous. Thus, we employed qPCR to quantify Campylobacter spp. in fresh- and marine-water samples, raw s...
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 کاملImproving Fluorometry as a Source Tracking Method to Detect Human Fecal Contamination in Georgia Waters
In a continuing effort to develop inexpensive source tracking methods to detect human fecal contamination in environmental waters, we combined targeted sampling with fluorometry. Targeted sampling works by identifying hotspots of fecal contamination through multiple samplings over everdecreasing distances. Fluorometry identifies human fecal contamination by detecting optical brighteners, primar...
متن کاملEstimated human health risks from exposure to recreational waters impacted by human and non-human sources of faecal contamination.
This work was conducted to determine whether estimated risks following exposure to recreational waters impacted by gull, chicken, pig, or cattle faecal contamination are substantially different than those associated with waters impacted by human sources such as treated wastewater. Previously published Quantitative Microbial Risk Assessment (QMRA) methods were employed and extended to meet these...
