| evaluation of physical, chemical and microbiological parameters of water quality in the harris neck estuarine marshes along the georgia coast. | analysis of the physical, chemical and biological parameters assessing water quality in harris neck estuary indicated that the average dissolved oxygen level was 8.6 mg/l, it maintained moderate levels of total dissolved nitrogen (2.7-4.6 mg/l) and total dissolved phosphorous (<0.05 mg/l), chlorophyll a was above 5.0 μg/l and it is contaminated with low levels of fecal bacteria. bifidobacterium adolescentis, a putative marker of human fecal pollution, was detected once at stations 3 and 5. overa ... | 2010 | 21122879 |
| quantification of enterococci and bifidobacteria in georgia estuaries using conventional and molecular methods. | fecal pollution is a serious threat to the estuarine environment along the georgia coast. culture-dependant and molecular methodologies were utilized to compare and evaluate the abundance of fecal indicator bacteria in four georgia estuaries (darien river, frederica river, gulley hole creek, and st. marys river). the functionality of enterococci and bifidobacteria as indicator organisms in marine environments was assessed, as well as bifidobacterium adolescentis densities. at each study site, en ... | 2008 | 18708238 |
| rapid detection of human fecal contamination in estuarine environments by pcr targeting of bifidobacterium adolescentis. | detection of bifidobacterium adolescentis was used as an effective genetic marker of human fecal contamination in georgia estuaries. enterococci enumerations on mei media indicated that a tributary to the little satilla river with 516 cfu/100 ml was the most polluted of all the rivers tested. extracted dna from eight river water samples was subjected to a two-step nested pcr protocol using genus and species specific primers for bifidobacterium spp. and b. adolescentis. b. adolescentis was detect ... | 2007 | 16876892 |
