Dr. Valerie Morley, an accomplished senior scientist at Ginkgo Bioworks, recently shed light on a widely untapped resource in public health – wastewater surveillance, and its significant role in monitoring antimicrobial resistance (AMR) in diverse environments. In her presentation delivered at the World AMR Congress, she delved deep into how wastewater data can potentially redraw our public health strategies against AMR. Her discussion revolved around the notable advantages of this type of surveillance, particularly in acquiring population-scale data that perfectly complements cultured clinical isolates.
According to Dr. Morley, wastewater surveillance represents a cost-effective solution for obtaining precise, population-specific data. This data source can be as broad as encompassing an entire community’s municipal-level wastewater or narrowly focused on wastewater hailing from a specific hospital ward. Importantly, it bridges the gap between community and healthcare settings, offering a more comprehensive view on AMR.
Despite the promise, Dr. Morley was also mindful of the hurdles to overcome in leveraging wastewater data effectively, particularly in associating AMR genes with respective bacterial organisms and interpreting metagenomic data. She addressed that the current shortcomings mainly stem from the limitations of existing sequencing approaches, but she was hopeful that strides were being made to enhance their accuracy and performance, despite their higher costs.
Leveraging collaboration and engaging with end-users are pivotal to derive meaningful conclusions. As per Dr. Morley, such collaborative efforts can further leverage the potential of wastewater surveillance, empowering healthcare organisations to streamline their antimicrobial stewardship and potentially reduce healthcare-associated infections through data correlations with electronic health records and large-scale pilot projects.
Concluding her insights, Dr. Morley reaffirmed the value of wastewater surveillance as an innovative tool for spotting AMR trends across community and healthcare settings. Significant challenges persist in data interpretation but the ongoing technological advancements and smarter data integrations provide a hopeful outlook. As a result, the application of wastewater surveillance could lead us towards a future of improved infection controls and antimicrobial stewardship.
