Surveillance of Emerging Pathogens and Antibiotic Resistances in Aquatic Ecosystems

Appropriate methods for wastewater-based epidemiology (WBE) and a better understanding of the fate of pathogenic viruses and antibiotic-resistant bacteria from the sources to river basins and estuaries are urgently required.

Our project will determine the prevalence of pathogenic viruses (including SARS-CoV-2), microbial indicators, antibiotic resistance, and microbial source tracking (MST) markers in wastewater, surface water, coastal sea waters, sediment and bivalve molluscan shellfish (BMS) in catchments located in different climate areas (Sweden, Germany, France, Spain, Portugal, Israel, Mozambique, and Uganda).

The project aims are: (i) method harmonization and training of European and African partners, (ii) SARS-CoV-2 detection in raw wastewater as a biomarker of COVID-19 cases, (iii) enteric viruses, antibiotic resistances and MST markers monitoring in aquatic environments, (iv) evaluation of sediments and BMS as integral reservoirs, (v) determination of the impact of climate and extreme weather events, and (vi) microbial risk assessment for water resources.

Sweden will perform sampling in the Göta Älv region and do virus analyzes for all partners.

Results and recommendations will be communicated to academia and stakeholders through scientific articles, conference presentations and through a stakeholder forum involving international health and environmental organizations, authorities and waterworks. Sweden will be represented by Swedish Water (Svenskt Vatten).
