| human adenoviruses and coliphages in urban runoff-impacted coastal waters of southern california. | a nested-pcr method was used to detect the occurrence of human adenovirus in coastal waters of southern california. twenty- to forty-liter water samples were collected from 12 beach locations from malibu to the border of mexico between february and march 1999. all sampling sites were located at mouths of major rivers and creeks. two ultrafiltration concentration methods, tangential flow filtration (tff) and vortex flow filtration (vff), were compared using six environmental samples. human adenov ... | 2001 | 11133443 |
| seasonal detection of human viruses and coliphage in newport bay, california. | recent studies have shown that the fecal indicator bacteria (fib) currently used to indicate water quality in the coastal environment may be inadequate to reflect human viral contamination. coliphage was suggested as a better indicator of human viral pollution and was proposed by the u.s. epa as an alternative indicator for fecal pollution in groundwater. in this study, we investigated the occurrence and distribution of fib, f+ coliphage, and pcr-detectable human adenovirus and enterovirus for a ... | 2007 | 17720839 |
| microbial source tracking in a small southern california urban watershed indicates wild animals and growth as the source of fecal bacteria. | three independent microbial source tracking (mst) methods were applied to a small urban subwatershed in orange county, california. fifty-seven water samples collected over summer 2002 were analyzed for human adenovirus and enterovirus. enterococci and e. coli were isolated for antibiotic resistance analysis (ara) and for pcr identification of human- and animal-specific toxin genes, respectively. all water samples were pcr negative for human enteroviruses and e. coli human-specific toxin gene. e. ... | 2007 | 17589839 |
| flow fingerprinting fecal pollution and suspended solids in stormwater runoff from an urban coastal watershed. | field studies were conducted to characterize the concentration vs streamflow relationships (or "flow fingerprints") of fecal pollution and suspended solids in stormwater runoff from the santa ana river watershed, the largest watershed in southern california. the concentrations of fecal indicator bacteria and f+ coliphages (viruses infecting e. coli) exhibit little-to-no dependence on streamflow rates, whereas the concentrations of total suspended solids (tss) exhibit a very strong (power-law) de ... | 2006 | 16903282 |
