ClearSelective enrichment of bacterial pathogens by microplastic biofilm
Researchers incubated biofilms on microplastics and natural substrates in freshwater and found that microplastic surfaces selectively enriched bacterial pathogens and antibiotic resistance genes compared to rock and leaf surfaces. The study suggests that microplastics in waterways may serve as hotspots for harmful bacteria and contribute to the spread of antibiotic resistance in the environment.
Microplastic biofilm as hotspots of antibiotic resistance genes and potential pathogens
This review examined how microplastic biofilms—the plastisphere—serve as hotspots for antibiotic resistance gene (ARG) accumulation and potential pathogen enrichment. The authors described mechanisms by which microplastic surfaces promote horizontal gene transfer and bacterial community shifts that favor ARG-carrying strains, raising concern that microplastics accelerate the spread of antibiotic resistance in aquatic environments.
A review focusing on mechanisms and ecological risks of enrichment and propagation of antibiotic resistance genes and mobile genetic elements by microplastic biofilms
This review examines how microplastics in water serve as surfaces for bacterial biofilms that harbor antibiotic resistance genes. The biofilms that form on microplastic surfaces can spread resistance genes to other bacteria and potentially to organisms that ingest them, including fish and ultimately humans. The authors highlight that microplastic-associated antibiotic resistance is an underappreciated public health risk that needs more research.
Biofilm formation on microplastics and interactions with antibiotics, antibiotic resistance genes and pathogens in aquatic environment
This review explains how microplastics in waterways develop bacterial biofilms on their surfaces that can harbor antibiotic-resistant bacteria and help spread antibiotic resistance genes to new environments. This is concerning for human health because these resistant microbes could eventually reach people through drinking water or seafood consumption.
Microplastics pollution in the ocean: Potential carrier of resistant bacteria and resistance genes
This review examined microplastics in marine environments as carriers of antibiotic-resistant bacteria and resistance genes, finding that plastic surfaces selectively enrich resistance genes through horizontal gene transfer and co-selection pressure, making ocean microplastics a vector for resistance dissemination across ecosystems.
Microplastics can selectively enrich intracellular and extracellular antibiotic resistant genes and shape different microbial communities in aquatic systems
Researchers examined how microplastics of different types selectively capture antibiotic resistance genes and shape microbial communities in aquatic systems. They found that microplastics enriched both intracellular and extracellular antibiotic resistance genes, with the enrichment patterns varying by plastic type. The study suggests that microplastics may serve as hotspots for the spread of antimicrobial resistance in wastewater and natural water environments.
Do microplastics promote the attachment of antimicrobial resistant pathogens?
Researchers examined whether microplastics promote the attachment and persistence of antimicrobial resistant (AMR) pathogens, finding that microplastics in aquatic environments frequently co-occur with AMR bacteria and antimicrobial residues, and may facilitate the spread of resistant pathogens.
New insight into the effect of microplastics on antibiotic resistance and bacterial community of biofilm
Researchers found that different types of microplastics promote distinct biofilm communities and enhance antibiotic resistance gene proliferation compared to natural substrates, suggesting microplastics serve as unique platforms for the spread of antimicrobial resistance.
The Microplastic-Antibiotic Resistance Connection
This review examined the link between microplastic pollution and antibiotic resistance, finding that microplastic surfaces in the environment selectively enrich antibiotic-resistant bacteria and resistance genes, creating hotspots that may amplify the spread of resistance far beyond clinical settings.
Microplastic-associated pathogens and antimicrobial resistance in environment
This review examines how microplastics in the environment act as surfaces for disease-causing bacteria and antibiotic-resistant microbes to colonize and spread. Researchers found that microplastics can carry pathogens and facilitate the transfer of antimicrobial resistance genes between bacteria in water systems. The findings raise concerns that microplastic pollution may be contributing to the growing global challenge of antibiotic resistance.
Microplastics in fresh- and wastewater are potential contributors to antibiotic resistance - A minireview
Researchers reviewed the link between microplastic pollution and the spread of antibiotic resistance in freshwater environments, finding that microplastic surfaces host unique bacterial communities enriched in antibiotic-resistant bacteria and the resistance genes they can share with other microbes. The close packing of bacteria in these plastic-surface biofilms may accelerate the spread of drug-resistant pathogens through drinking water sources, though the full health implications remain poorly understood.
Microplastics: Hidden drivers of antimicrobial resistance in aquatic systems
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.

Enrichment of Antibiotic Resistance Genes on Plastic Waste in Aquatic Ecosystems, Aquatic Animals, and Fishery Products
This review examines how plastic waste in water creates surfaces where antibiotic-resistant bacteria thrive and share resistance genes with each other. Microplastics in rivers, oceans, and fish farms were consistently found to harbor more antibiotic resistance genes than natural materials like rocks or sand. Since fish and shellfish can accumulate these microplastic-associated resistant bacteria, there is a risk that drug-resistant infections could reach humans through the seafood supply chain.
