This rapid evidence assessment (REA) will collate and critically evaluate published and grey research literature to identify which pathways are most responsible for disseminating ‘resistance’ from the aquatic environment into humans. The REA will also describe the volume, nature and characteristics of key findings, identify knowledge gaps and implications for policy and research.
The emergence of antibiotic resistant bacteria of clinical significance, is one of the greatest global threats to humanity. Aquatic environments are not only reservoirs of clinically important antibiotic resistant bacteria (ARB), antimicrobial resistance (AMR) and antibiotic resistance genes (ARGs) but also as a medium for the spread and evolution of resistance genes. The routes by which humans can come into contact with these resistant bacteria and microbes via aquatic environments are numerous. For example the consumption of irrigated crops, shellfish, fish or drinking water, and recreational water sports. This REA aims to provide a better understanding of the pathways that are most responsible for disseminating ‘resistance’ from the aquatic environment into humans so that relevant authorities are better placed to develop effective strategies for dealing with the risks.
The primary question of the REA is:
‘What pathways are most responsible for disseminating ‘resistance’ from the aquatic environment into humans?’
Two secondary questions will also be addressed:
1. ‘What are the factors affecting the transmission of AMR and ARGs from the water environment into humans?’
2. ’What evidence is there that exposure to the pathways is contributing to clinical infections that cannot be treated with existing antibiotics?’
