River networks are one of the main routes by which public could be exposed to environmental sources antibiotic resistance, that may introduced e.g. via treated wastewater. In this study, we applied a comprehensive integrated analysis encompassing mass-flow concepts, chemistry, bacterial plate counts, resistance gene quantification and shotgun metagenomics track fate resistome (collective genes (ARGs) in microbial community) wastewater two Swiss rivers at kilometer scale. The levels certain...
Abstract Wastewater treatment plants (WWTPs) are key sources of antimicrobial resistance genes (ARGs) that could influence the resistomes microbial communities in various habitats receiving river ecosystem. However, it is currently unknown which most impacted and whether ARGs, like certain chemical contaminants, be accumulated or enriched We conducted a systematic metagenomic survey on antibiotic WWTP effluent, four riverine (water, suspended particles, sediment, epilithic biofilm),...
Understanding factors associated with antimicrobial resistance (AMR) distribution across populations is a necessary step in planning mitigation measures. While associations between AMR and socioeconomic-status (SES), including employment education have been increasingly recognized low- middle-income settings, connections are less clear high-income countries where SES remains an important influence on other health outcomes. We explored the relationship Calgary, Canada using spatially-resolved...
Abstract Background Hepatitis A virus (HAV) incident infection in Canada is rarely diagnosed (i.e. incidence of 3.6-10 cases/100,000 persons) (PMID: 18159360). Infections generally relate to imported contaminated food-products, or travelers returning from endemic countries. Due its fecal-oral spread, possible underdiagnosis, and often-cryptic presentation, HAV an ideal candidate for wastewater (WW)-based surveillance, a tool increasingly utilized monitor infectious diseases globally.Figure...
Wastewater-based surveillance (WBS) has been established as a powerful tool that can guide health policy at multiple levels of government. However, this approach not well assessed more granular scales, including large work sites such University campuses. Between August 2021 and April 2022, we explored the occurrence SARS-CoV-2 RNA in wastewater using qPCR assays from complimentary sewer catchments residential buildings spanning Calgary's campus how compared to municipal treatment plant...

Wastewater treatment plants are ‘hotspots’ for antibiotic resistance genes and bacteria but sewer overflows exacerbate the problem by disseminating them into rivers. Swiss researchers suggest ways to minimise these effects.
