ClearReshaping the antibiotic resistance genes in plastisphere upon deposition in sediment-water interface: Dynamic evolution and propagation mechanism
Researchers examined how antibiotic resistance genes in the microplastic biofilm (plastisphere) evolve as MPs settle from water to sediment, finding that deposition in sediment reshapes ARG profiles and promotes horizontal gene transfer, amplifying resistance gene reservoirs in benthic environments.
Microplastics and their role in the emergence of antibiotic resistance in bacteria as a threat for the environment
Researchers reviewed how microplastics act as breeding grounds for antibiotic-resistant bacteria by providing surfaces where bacteria can swap resistance genes with each other — a process called horizontal gene transfer. This dual threat of plastic pollution and antibiotic resistance is compounding into a significant global public health crisis.
Antibiotic resistant bacteria colonising microplastics in the aquatic environment: An emerging challenge
Researchers reviewed how microplastics in aquatic environments act as surfaces where antibiotic-resistant bacteria can grow and swap resistance genes with each other, raising concern that contaminated seafood and water could transfer these hard-to-treat bacteria to humans.
Antibiotic resistance in plastisphere
Researchers reviewed antibiotic resistance in the plastisphere — the microbial community colonizing plastic surfaces in aquatic environments — finding that plastic properties and aging influence the enrichment and horizontal transfer of antibiotic resistance genes, and that aged microplastics pose elevated risks due to increased adsorption of resistant bacteria.
How nanoscale plastics facilitate the evolution of antibiotic resistance?
Researchers explored how nanoscale plastic particles promote the evolution of antibiotic resistance in bacteria. They found that exposure to nanoplastics increased oxidative stress in bacteria, which in turn accelerated mutations and horizontal gene transfer that confer resistance to antibiotics. The study suggests that nanoplastic pollution could be an overlooked factor contributing to the global antibiotic resistance crisis.
Selection for antimicrobial resistance in the plastisphere
This review examines how microplastics in the environment may contribute to the spread of antimicrobial resistance by providing surfaces where bacteria, antibiotics, and resistant genes converge. Researchers describe several mechanisms by which the microbial communities living on microplastics, known as the plastisphere, could accelerate horizontal gene transfer of resistance traits. The study highlights an emerging concern at the intersection of plastic pollution and the global antimicrobial resistance crisis.
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.
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.
What is the micro- and nanoplastics impact on pathogenic microorganisms?
This perspective piece reviewed emerging evidence on how micro- and nanoplastics interact with pathogenic microorganisms, potentially enhancing pathogen survival, antibiotic resistance gene transfer, and virulence. The authors highlight the plastisphere as a habitat that may selectively enrich and amplify microbial pathogens.
Foodborne pathogens in the plastisphere: Can microplastics in the food chain threaten microbial food safety?
This review examines the potential for microplastics to act as vectors for foodborne pathogens in the food chain, synthesizing current evidence on pathogen attachment to the plastisphere, the effects of microplastics on bacterial virulence and evolution, and the implications for simultaneous uptake of microplastics and pathogens in the human gut.
Potential impact of marine-derived plastisphere as a Vibrio carrier on marine ecosystems: Current status and future perspectives
This review examines how microplastics in the ocean serve as floating platforms for Vibrio bacteria, which are significant pathogens threatening aquaculture and marine ecosystem health. Researchers found that the so-called plastisphere, the microbial community that colonizes plastic surfaces, can enhance the survival and spread of these harmful bacteria. The study highlights a concerning link between plastic pollution and the potential amplification of waterborne disease risks.

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.
Plastics and Microplastics as Vectors for Bacteria and Human Pathogens
This study reviewed how marine plastic debris serves as a surface for bacterial colonization, including human pathogens, and examined the novel communities forming on plastic surfaces. The research raises public health concerns about microplastics acting as rafts that transport harmful bacteria to new locations, including to seafood and coastal recreational areas.
Watershed urbanization enhances the enrichment of pathogenic bacteria and antibiotic resistance genes on microplastics in the water environment
Researchers compared microplastic biofilm communities (the plastisphere) across watersheds with different levels of urbanization, finding that higher urbanization enriched pathogenic bacteria and antibiotic resistance genes on plastic surfaces in waterways. The study suggests that urban runoff substantially elevates the health risk posed by microplastics as vectors of pathogens and antimicrobial resistance.
Environmental drivers of antibiotic resistance: Synergistic effects of climate change, co-pollutants, and microplastics
This review examines how climate change, chemical pollutants, and microplastics work together to accelerate the spread of antibiotic resistance, a growing global health crisis. Microplastics provide surfaces where bacteria form communities that exchange resistance genes, and as these plastics age in the environment, they become even better at absorbing other pollutants, creating hotspots that amplify drug resistance.
Deciphering the pathogenic risks of microplastics as emerging particulate organic matter in aquatic ecosystem
Researchers compared how microplastics and natural organic matter like leaves and algae affect bacterial communities in aquatic environments. The study found that microplastics uniquely promoted pathogenic bacteria as keystone species and amplified their capacity to host antibiotic resistance genes, suggesting that microplastic pollution may pose distinct pathogenic risks beyond those of natural particles.
Role of traveling microplastics as bacterial carriers based on spatial and temporal dynamics of bacterial communities
Researchers tracked how the bacterial communities on traveling microplastics gradually shift to match the communities on local microplastics, a process called localization, finding that spatial and temporal dynamics of bacterial colonization determine microplastics' role as vectors for bacteria across environments.
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.
