Traditional and molecular analyses for fecal indicator bacteria in non-point source subtropical recreational marine waters.
The use of enterococci as the primary fecal indicator bacteria (FIB) for the determination of recreational water safety has been questioned, particularly in sub/tropical marine waters without known point sources of sewage. Alternative FIB (such as the Bacteroidales group) and alternative measurement methods (such as rapid molecular testing) have been proposed to supplement or replace current ma...
متن کاملDecay Rates of Faecal Indicator Organisms and Pathogens: Use of Microcosm and In Situ Studies for the Estimation of Exposure Risk in Recreational Waters
This three year study compared the decay of the commonly used faecal indicator organisms Escherichia coli, enterococci and coliphage in coastal water and sediment using laboratory based microcosms with that for the pathogens Salmonella typhimurium and S. derby. Results from the laboratory study were validated with in-situ decay rates of faecal coliforms observed at a recreational coastal site f...
متن کاملGeneric Modelling of Faecal Indicator Organism Concentrations in the UK
To meet European Water Framework Directive requirements, data are needed on faecal indicator organism (FIO) concentrations in rivers to enable the more heavily polluted to be targeted for remedial action. Due to the paucity of FIO data for the UK, especially under high-flow hydrograph event conditions, there is an urgent need by the policy community for generic models that can accurately predic...
متن کاملComparison of decay rates of faecal indicator organisms in recreational coastal water and sediment
A laboratory based microcosm study utilising intact non-sterile sediment cores was undertaken to determine the survival of the faecal indicator organisms Escherichia coli, Enterococcus faecium and somatic coliphage in both recreational coastal water and sediment. Overlying water was inoculated with the test organisms and incubated at 10°C, 20°C or 30°C. E. coli, enterococcus and coliphage were ...
متن کاملEffectiveness of guideline faecal indicator organism values in estimation of exposure risk at recreational coastal sites.
Decay rates in coastal water and sediment for the bacterial pathogens Salmonella typhimurium and S. derby were compared in laboratory-based microcosms with results previously obtained for a number of faecal indicators. In general, the decay rates of Salmonella spp. were greater than either enterococci or coliphage in overlying water and sediment. Decay rates of E. coli were similar to Salmonell...
