To celebrate this year’s World Antibiotic Awareness Week, Resistomap is organizing a series of live webinars from August to November 2020. This webinar series aims to improve public awareness and understanding of antibiotic resistance and its environmental impact.
Water environments have the potential to become hotspots for antibiotic resistance. Understanding the role of water in the emergence and spread of antibiotic resistance is crucial to address this global health threat. In the September webinar, our speakers will discuss the topic of antibiotic resistance in water environments.

Acquired antibiotic resistance emerged with the first therapeutic uses of antibacterial drugs, more than 80 years ago. Over decades antibiotic resistant bacteria were reported in clinical settings and considered a major problem spreading in hospitals, mainly among
immunocompromised and debilitated patients. Gradually, the situation changed: today it is known that antibiotic resistant infections can affect anyone, no matter the age, health condition or the country where one lives. Moreover, antibiotic resistance is no longer an
exclusive clinical setting issue, it is spread over humans, animals, plants and the environment. The One-Health vision is therefore necessary to better understand how does antibiotic resistance spread from major sources, humans and animals. The impact of different emission sources on the accumulation and spread of antibiotic resistant bacteria and antibiotic resistance genes in the environment has been mainly assessed based on the abundance and prevalence of these self-replicative biological contaminants. However, there are different reasons to believe that this approach may be of limited value to assess risks. These evidences highlight the uncertainty that hampers the establishment of solid recommendations to control antibiotic resistance dissemination and
major challenges to regulate practices such as manure soil fertilization or water reuse.

Antibiotic resistant bacteria and resistance genes are emitted to surface water from human waste, including from wastewater treatment plants and point sources such as hospitals within the urban sewer network, but also from sewage overflows. In addition, fertilization of agricultural fields with animal manure can lead to contamination of water courses through run-off. In this presentation, studies to map the relative importance of these impacts within the Dutch National Action Plan on Antibiotic Resistance are summarized. These include studies on the presence and sources of ESBL, carbapenemase-producing Enterobacteriaceae and of resistance genes in water courses. In addition, the WHO Tricycle project on One Health surveillance of AMR in an international context is described.

Célia M. Manaia is an associate professor at Escola Superior de Biotecnologia, Universidade Católica Portuguesa and Vice-President for Research and Internationalization at the Porto
Regional Center of the Universidade Católica Portuguesa.
Her research in the field of antibiotic resistance, typically in multidisciplinary teams, had tackled the biological processes involved in resistance dissemination and control involving engineering-based solutions. In the last years she has been involved as leader or participant in different national and international projects, of basic research, applied research and
mobility/networking with relevant impacts in the area.

Heike Schmitt is principal investigator on AMR in the environment at the National Institute for Public Health and the Environment (RIVM) in the Netherlands. She leads the environmental part of the Dutch National Action Plan on AMR, and has addressed wastewater based epidemiology (WBE) for several years, focusing on wastewater analysis to monitor circulation of WHO resistant priority pathogens in the general population. She works on capacity building for international surveillance of antibiotic resistance, and on the relevance of inadequate WASH for exposure to AMR, within the WHO Collaborating Center on Risk Assessment of Pathogens in Food and Water. In addition, she serves as research advisor at the European centre of excellence for sustainable water technology (WETSUS),and as researcher at Utrecht University.
