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.
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.
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.
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.
Microplastic-Mediated Dissemination of Antibiotic Resistance Genes in Marine Environments: Mechanisms, Environmental Modulators, and Emerging Risks
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.
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.
Alteration of microbial mediated carbon cycle and antibiotic resistance genes during plastisphere formation in coastal area
Researchers investigated how microplastic surfaces in coastal environments develop biofilm communities, known as the plastisphere, and whether these biofilms enrich antibiotic resistance genes. The study found that incubation time, habitat type, and microplastic aging state all significantly influenced biofilm composition, and that aged microplastics accumulated more antibiotic resistance genes than new ones, suggesting microplastics may serve as vectors for spreading resistant bacteria.
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.
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.
Hidden threats in the plastisphere: Carbapenemase-producing Enterobacterales colonizing microplastics in river water
Researchers placed microplastics in a river near a wastewater treatment plant and found that antibiotic-resistant bacteria, including dangerous carbapenem-resistant strains, colonized the plastic surfaces. These bacteria carried multiple drug-resistance genes and virulence traits, making them potential threats to human health. The study demonstrates that microplastics in waterways can serve as floating platforms that help spread antibiotic-resistant superbugs from wastewater into the broader environment.
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.
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.
