| rapidly measured indicators of recreational water quality and swimming-associated illness at marine beaches: a prospective cohort study. | in the united states and elsewhere, recreational water quality is monitored for fecal indicator bacteria to help prevent swimming-associated illnesses. standard methods to measure these bacteria take at least 24 hours to obtain results. molecular approaches such as quantitative polymerase chain reaction (qpcr) can estimate these bacteria faster, in under 3 hours. previously, we demonstrated that measurements of the fecal indicator bacteria enterococcus using qpcr were associated with gastrointes ... | 2010 | 21040526 |
