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...
To meet increasing urban water requirements in a sustainable way, there is need to diversify future sources of supply and storage. However, date, has been lag the uptake managed aquifer recharge (MAR) for diversifying areas. This study draws on examples use MAR as an approach support management. Recharged may be sourced from variety centers, provides means recycle underutilized storm treated wastewater maximize their resource potential minimize any detrimental effects associated with...
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.

ABSTRACT Recreational and potable water supplies polluted with human wastewater can pose a direct health risk to humans. Therefore, sensitive detection of fecal pollution in environmental waters is very important quality authorities around the globe. Microbial source tracking (MST) utilizes markers (HFMs) detect waters. The concentrations these raw are considered because it likely that marker whose concentration high will be more frequently detected In this study, quantitative PCR (qPCR)...
Environmental oligotrophic bacteria are suspected to be highly relevant carriers of antimicrobial resistance (AMR). However, there is a lack validated methods for monitoring in the aquatic environment. Since extended-spectrum β-lactamases (ESBLs) play particularly important role clinical sector, culturing method based on R2A-medium, spiked with different combinations β-lactams, was applied quantify β-lactamase-producing environmental from surface waters. In German water samples (n = 28),...
The objective of the Parafield Aquifer Storage Transfer and Recovery research project in South Australia is to determine whether stormwater from an urban catchment that treated a constructed wetland stored initially brackish aquifer before recovery can meet potable water standards. produced by harvesting system, which included wetland, was found be near quality. Parameters exceeding drinking guidelines recharge small numbers fecal indicator bacteria elevated iron concentrations associated...
ABSTRACT This study was aimed at evaluating the host specificity and sensitivity of two bovine feces-associated bacterial (BacCow-UCD cowM3) one viral [bovine adenovirus (B-AVs)] microbial source tracking (MST) markers by screening 130 fecal wastewater samples from 10 target nontarget groups in southeast Queensland, Australia. In addition, 36 water were collected a reservoir tested for occurrence all three along with indicator bacteria (FIB), Campylobacter spp., Escherichia coli O157,...
