Summary
This review examines bacterial extracellular vesicles as overlooked vectors for antibiotic resistance dissemination in aquatic ecosystems. The authors synthesise evidence that EVs facilitate horizontal gene transfer independently of classical mechanisms, presenting a potential public health concern in food and water systems. The work emphasises the need to account for EV-mediated transmission when assessing antibiotic resistance spread in environmental compartments.
Regional applicability
Findings are relevant to UK water quality standards, food safety regulation, and sewage treatment protocols, particularly given the role of aquatic environments as resistance reservoirs. The identification of EVs as transmission vectors may inform environmental monitoring and mitigation strategies in UK agricultural runoff and wastewater management.
Key measures
Mechanisms of EV-mediated gene transfer; prevalence and characteristics of antibiotic resistance genes in aquatic bacterial populations; environmental factors influencing EV production and resistance dissemination
Outcomes reported
The study examines the role of bacterial extracellular vesicles (EVs) in facilitating the horizontal transfer of antibiotic resistance genes in aquatic environments. It synthesises evidence on mechanisms by which EVs mediate resistance spread independently of direct cell-to-cell contact.
