ClearMicroplastisphere 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.
Microplastisphere may induce the enrichment of antibiotic resistance genes on microplastics in aquatic environments: A review
This first meta-analysis of antibiotic resistance gene (ARG) enrichment on microplastics found that ARGs were more abundant on microplastic surfaces than on inorganic substrates or in surrounding water, but less abundant than on natural organic substrates. Freshwater microplastics showed a higher degree of ARG enrichment than those in saline water or sewage.
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.
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.
Plastisphere as a Vector for Pathogenic Microbes and Antibiotic Resistance
This review examines how the plastisphere, the microbial community that colonizes plastic surfaces, serves as a vector for pathogenic bacteria and antibiotic resistance genes. Researchers found that microplastics can adsorb antibiotics and facilitate higher rates of plasmid transfer among bacteria, with potentially pathogenic species carrying multi-drug resistance genes identified on plastic surfaces.
The Plastisphere Resistome: A Systematic Review of Antibiotic Resistance Genes and Resistant Bacteria on Microplastics
This systematic review examines whether microplastic-associated biofilms harbor higher levels of antibiotic-resistant bacteria compared to surrounding environments. If microplastics act as hotspots for antibiotic resistance genes, they could spread drug-resistant bacteria through water systems, posing a serious concern for human health and the effectiveness of antibiotics.
Microplastics: Disseminators of antibiotic resistance genes and pathogenic bacteria
This review examined the role of microplastics as carriers of antibiotic resistance genes (ARGs) and pathogenic bacteria, analyzing how plastisphere biofilms concentrate and spread AMR through air, water, and soil environments. The evidence supports MPs as global vectors for antimicrobial resistance dissemination with implications for human health.
Selective enrichment of antibiotic resistome and bacterial pathogens by aquatic microplastics
This review found that microplastics in aquatic environments selectively enrich antibiotic-resistant bacteria, resistance genes, and bacterial pathogens in their biofilms, making plastic debris a potential vector for spreading antimicrobial resistance.
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.
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. Microplastics serve as substrates for ARG-carrying biofilms (plastispheres), facilitating the spread of antibiotic resistance across ecosystems.
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.
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.
[Research progress on the effect of estuary microplastics on antibiotic resistance genes].
This review summarizes research on how microplastics in estuarine environments influence the spread of antibiotic resistance genes (ARGs), focusing on the role of biofilms that form on plastic surfaces. Microplastic biofilms selectively enrich ARG-carrying bacteria and facilitate horizontal gene transfer, increasing the risk of antibiotic resistance dissemination in ecologically and humanly important estuarine zones.
Regulation of ARGs abundance by biofilm colonization on microplastics under selective pressure of antibiotics in river water environment
Researchers investigated how biofilms forming on microplastics in river water affect the spread of antibiotic resistance genes under antibiotic pressure. They found that the presence of antibiotics accelerated biofilm colonization on microplastic surfaces and significantly increased the abundance of resistance genes compared to conditions without antibiotics. The study suggests that microplastics in waterways may serve as hotspots for the development and transfer of antibiotic resistance.
Antibiotic Resistance Gene Enrichment on Plastic Wastes in Aquatic Ecosystems and Fishery Products
This review examined how plastic waste in aquatic environments enriches antibiotic resistance genes (ARGs) through plastisphere biofilms, with implications for fishery product safety. Microplastic-associated biofilms concentrate ARG-carrying bacteria, increasing the risk of antibiotic resistance transmission through fish and other seafood consumed by humans.
