Hidden Interfaces of Antibiotic Resistance Genes: How Plastispheres Threaten Environmental Integrity, Health Security, and One Health Systems
AI summary Read the abstract
This review of over 100 studies finds that tiny plastic bits floating in water and soil become coated with bacteria that can trade antibiotic resistant genes with each other, potentially making infections harder to treat. Even "biodegradable" plastics aren't off the hook, as they can actually grow thicker bacterial coatings that spread resistance faster. The researchers say wastewater treatment plants and farms using treated sludge are key places to monitor and control this hidden risk.
Microplastics have emerged as critical environmental pollutants, forming plastisphere biofilms that act as hubs for Antibiotic Resistance Gene (ARG) enrichment and dissemination. This study adopts a One Health perspective to examine the ecological and public health implications of plastispheres in spreading antimicrobial resistance across environmental, animal, and human domains. This review synthesizes evidence from 102 studies which examine plastisphere-associated ARG dynamics through an integrated One Health framework. This review integrates polymer characteristics, plastisphere ecology, ARG transfer mechanisms, including environmental exposure pathways, treatment options, surface hydrophobicity, environmental aging, biofilm maturation, and the adsorption of antibiotics and metals. Plastisphere biofilms may facilitate horizontal gene transfer through conjugation, transformation, and transduction by increasing microbial density, retaining extracellular DNA, and concentrating mobile genetic elements, co-selective contaminants and regulatory gaps within a unified One Health framework. Regulatory standards, emphasizing updated polymer evaluation criteria, ARG-inclusive monitoring systems, and waste management policies were considered. Mitigation strategies such as filtration technologies, sludge regulation, wastewater optimization and investigation were integrated into the system. The principal contribution of this review is the integration of polymer-level characteristics, microbial mechanisms of resistance transfer, environmental dissemination pathways, and management interventions within a single One Health framework. This synthesis identifies wastewater treatment plants, sludge application, agricultural reuse, and interconnected aquatic systems as important control points requiring coordinated monitoring and mitigation. • Plastisphere biofilms enrich and mobilize antibiotic resistance genes across systems. • Polymer chemistry and aging shape microbial colonization and ARG persistence. • Biodegradable plastics can accelerate ARG spread by fueling dense biofilms. • Wastewater and sludge act as critical nodes linking MPs to One Health risks. • Global monitoring needs unified protocols to track microplastics and ARGs together.

The Microplastic–biofilm–resistome Nexus: the Role of Environmental Microplastics in the Formation and Dissemination of Antibiotic-resistant Bacteria and the Potential Consequences for Human Health
AI summary Read the abstract
Tiny plastic bits (microplastics) that end up in water and soil aren't just pollution, they can act like rafts where bacteria cluster together and swap genes that help them resist antibiotics. This review pulls together existing research suggesting these plastic "biofilms" could be a hidden pathway for drug-resistant germs to spread through the environment and potentially reach humans. While more research is needed to confirm real-world health risks, it's a reminder that plastic pollution and the growing problem of antibiotic resistance may be more connected than we think.

Tiny plastic particles floating in water and soil aren't just pollution, they can act like rafts where bacteria cluster together and swap genes that help them resist antibiotics. This review pulls together existing research suggesting that these plastic-bacteria communities could be a hidden pathway for drug-resistant "superbugs" to spread through the environment and potentially reach humans. While more research is needed to confirm the real-world health risk, it's a reminder that plastic pollution may have ripple effects beyond what we can see.
The plastisphere as a nexus for antimicrobial resistance: micro(nano)plastics in pathogen colonization, gene transfer, and global health risks
AI summary Read the abstract
This review characterizes the plastisphere — microbial communities colonizing microplastic surfaces — as a triple threat that serves simultaneously as a habitat for pathogens, a reservoir for antibiotic resistance genes, and a facilitator of horizontal gene transfer across ecosystems. The convergence of microplastic pollution and antimicrobial resistance represents an underappreciated global health crisis requiring integrated One Health surveillance strategies.
Microplastics: Hidden drivers of antimicrobial resistance in aquatic systems
AI summary Read the abstract
This review examines how microplastics in aquatic environments serve as surfaces for biofilm formation, creating what researchers call the 'plastisphere,' which can harbor antibiotic-resistant bacteria and pathogens. Evidence indicates that microplastics facilitate the spread of antimicrobial resistance genes through water systems, potentially affecting both aquatic organisms and human health. The findings underscore microplastics as an overlooked driver of antibiotic resistance in waterways.
Micro- and Nanoplastics: Hidden Environmental Catalysts of Antimicrobial Resistance
AI summary Read the abstract
Tiny plastic bits called microplastics and nanoplastics — created when larger plastic waste breaks down from sun exposure, weather, and other natural processes — have become so small and widespread that they're now found throughout our water, soil, and air. This review paper highlights growing concerns that these particles may act as hidden carriers that help bacteria develop resistance to antibiotics, though more research is needed to fully understand this risk. Since antibiotic resistance already makes some infections harder to treat, understanding whether plastic pollution is making the problem worse matters for protecting public health going forward.
