Clear[Influencing Factors and Mechanisms of Antibiotic Resistance Gene Enrichment by Microplastics in the Environment].
This review examines how microplastics in the environment serve as carriers for antibiotic resistance genes, enriching and spreading resistant bacteria across air, soil, water, and sediments. Researchers found that the type, surface characteristics, and aging of microplastics all influence how effectively they accumulate resistance genes and facilitate horizontal gene transfer. The findings highlight the need to consider microplastics as an important vector in the environmental spread of antibiotic resistance.
Microplastics are a hotspot for antibiotic resistance genes: Progress and perspective
This review examines growing evidence that microplastics serve as hotspots for antibiotic resistance genes in the environment. Researchers found that microplastics selectively accumulate antibiotic-resistant bacteria and resistance genes on their surfaces across wastewater, aquatic, and terrestrial environments. The dense bacterial communities and concentrated pollutants on microplastic surfaces create favorable conditions for the spread and evolution of antibiotic resistance, raising concerns about potential risks to human health.
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.
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.
The Impact of Microplastics on Antibiotic Resistance Genes
This review analyzed the distribution, migration, and transfer pathways of antibiotic resistance genes (ARGs) in relation to microplastics in environmental systems.

Unraveling the effect of micro/nanoplastics on the occurrence and horizontal transfer of environmental antibiotic resistance genes: Advances, mechanisms and future prospects
This review examines how micro- and nanoplastics promote the spread of antibiotic resistance genes in the environment. The tiny plastic particles create conditions that help bacteria exchange resistance genes more easily by generating oxidative stress, making cell membranes more permeable, and providing surfaces where resistant bacteria can form communities. This is a growing public health concern because antibiotic-resistant infections are increasingly difficult to treat.
Microplastics as emerging reservoirs of antimicrobial resistance: Clinical relevance and environmental mechanisms
This review examines how microplastics act as environmental reservoirs for antibiotic resistance genes, creating selective microenvironments through antibiotic and metal adsorption, biofilm formation, and horizontal gene transfer, with potential pathways to clinical human exposure.
How microplastics and nanoplastics shape antibiotic resistance?
This review examines how micro- and nanoplastics act as vectors for antibiotic resistance genes, facilitating their spread through environmental and biological systems by creating selective pressure and hosting microbial communities that exchange resistance determinants.

This review examines the role of microplastics in maintaining and spreading antibiotic resistance genes in marine ecosystems, synthesizing evidence that plastic pollution in aquatic environments creates reservoirs for antimicrobial resistant bacteria and facilitates horizontal gene transfer.
A review on the effect of micro- and nano-plastics pollution on the emergence of antimicrobial resistance
This review highlights how microplastics serve as breeding grounds for antimicrobial resistance genes, examining the overlooked interaction between plastic pollution and antibiotic resistance that poses combined threats to environmental and human health.
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.

This review examines how microplastics in the environment serve as surfaces where antibiotic-resistant bacteria can grow and exchange resistance genes, potentially worsening the global antimicrobial resistance crisis. Researchers found that the unique surface properties of micro- and nanoplastics create favorable conditions for the spread of antibiotic resistance genes among microorganisms. The study highlights that microplastic pollution and antibiotic resistance are interconnected environmental health challenges that may need to be addressed together.
Microplastisphere antibiotic resistance genes: A bird's-eye view on the plastic-specific diversity and enrichment
Microplastics in the environment act as surfaces for microbial communities called microplastispheres, which this review finds are enriched with antibiotic resistance genes (ARGs). The type of plastic, surrounding water chemistry, and co-occurring pollutants all influence which resistance genes accumulate, raising concern that microplastics could be spreading antibiotic resistance through aquatic environments worldwide.
How micro-/nano-plastics influence the horizontal transfer of antibiotic resistance genes - A review
This review examines how micro- and nanoplastics help spread antibiotic resistance genes between bacteria -- a major global health threat. The tiny plastic particles can act as platforms where bacteria exchange DNA carrying drug-resistance instructions, potentially making infections harder to treat. The effect depends on the type, size, and concentration of plastics, and has been documented in sewage, livestock farms, and landfills.

This review examines how microplastics serve as vectors for spreading antibiotic resistance genes in marine environments through biofilm formation and horizontal gene transfer. Researchers found that plastic surfaces promote colonization by resistant bacteria, and environmental factors like salinity, UV exposure, and co-occurring heavy metals further accelerate the spread of resistance genes, posing significant ecological and public health risks.
Marine plastisphere selectively enriches microbial assemblages and antibiotic resistance genes during long-term cultivation periods
Researchers placed four types of common microplastics in a marine environment for over 100 days and found that bacterial communities and antibiotic resistance genes accumulated on the plastic surfaces over time. PVC microplastics were particularly effective at concentrating resistance genes, and a key gene-transfer element was found on all plastic types. These results show that microplastics floating in the ocean act as hotspots for antibiotic-resistant bacteria, which could eventually reach humans through seafood or water.
