Comparative 16S rRNA sequencing was used to evaluate phylogenetic relationships among selected strains of ammonia- and nitrite-oxidizing bacteria. All characterized were shown be affiliated with the proteobacteria. The study extended recent rRNA-based studies diversity nitrifiers by comparison eight genus Nitrobacter representatives genera Nitrospira Nitrospina. later delta subdivision proteobacteria but did not share a specific relationship each other or members subdivision. constituted...
The prevalence and proliferation of antibiotic resistant bacteria is profoundly important to human health, but the extent which aquatic environments contribute toward dissemination genes (ARGs) poorly understood. 24 ARGs active against eight classes (β-lactams, aminoglycosides, glycopeptides, chloramphenicols, tetracycline, macrolides, trimethoprim, sulfonamides) was evaluated in surface water samples collected from Germany Australia with culture independent methods. most frequently detected...
ABSTRACT Pathogenic human viruses cause over half of gastroenteritis cases associated with recreational water use worldwide. They are relatively difficult to concentrate from environmental waters due typically low concentrations and their small size. Although rapid enumeration by quantitative PCR (qPCR) has the potential greatly improve quality analysis risk assessment, upstream steps capturing recovering sources along removing inhibitors extracted nucleic acids remain formidable barriers...
The reporter gene assay AREc32 is based on the induction of Nrf2 mediated oxidative stress response pathway in human breast cancer cell line MCF7, where eight copies antioxidant element (ARE) are linked to a encoding for luciferase. Nrf2-ARE responsive many chemicals that cause stress, among them large number pesticides and skin irritants. We adopted validated bioassay water quality testing. tert-Butylhydroquinone served as positive control, phenol negative control other reactive were...
Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe recent years as an efficient means recycling stormwater or treated sewage effluent for non-potable indirect potable reuse urban rural areas. Yet aquifers have been relied on knowingly water storage unwittingly treatment millennia. Hence if 'leading edge' is defined 'the foremost part a trend; vanguard', it would be misleading to claim managed aquifer recharge leading edge technology. However taken...
ABSTRACT In this study, the microbiological quality of household tap water samples fed from rainwater tanks was assessed by monitoring numbers Escherichia coli bacteria and enterococci 24 households in Southeast Queensland (SEQ), Australia. Quantitative PCR (qPCR) also used for quantitative detection zoonotic pathogens connected taps. The were estimated fecal possums various species birds using qPCR, as are considered to be potential sources contamination roof-harvested (RHRW). Among...
ABSTRACT Escherichia coli isolates ( n = 300) collected from six sites in subtropical Brisbane, Australia, prior to and after storm events were tested for the presence of 11 virulence genes (VGs) specific diarrheagenic pathotypes. The eaeA , stx 1 2 ehxA enterohemorrhagic E. (EHEC) pathotype was detected 56%, 6%, 10%, 13% isolates, respectively. VGs astA (69%) aggR (29%), carried by enteroaggregative (EAEC) pathotypes, frequently isolates. enteropathogenic (EPEC) gene bfp 24% In addition,...
In this study, host-associated molecular markers and bacterial 16S rRNA gene community analysis using high-throughput sequencing were used to identify the sources of fecal pollution in environmental waters Brisbane, Australia. A total 92 composite wastewater samples collected from different host groups (cat, cattle, dog, horse, human, kangaroo), 18 water six sites (BR1 BR6) along Brisbane River Queensland, Bacterial communities fecal, wastewater, river sequenced. Water also tested for...
