Microplastics as a novel facilitator for antimicrobial resistance: Effects of concentration, composition, and size on Escherichia coli multidrug resistance
This study examined how microplastics facilitate antimicrobial resistance by acting as a surface for the co-selection of resistant bacteria, finding that plastic surfaces enrich resistance genes and transfer-capable elements in aquatic environments.
Marine outfall discharges contribute to coastal microplastic pollution and the spread of antimicrobial resistance
Researchers investigated how marine outfall discharges from wastewater treatment plants contribute to coastal microplastic pollution and the spread of antibiotic-resistant bacteria. They found that microplastics in treated wastewater effluent can serve as reservoirs for multidrug-resistant bacteria, potentially transferring them to the marine environment. The study challenges current regulations that permit marine outfall disposal and suggests that microplastics may facilitate the spread of antimicrobial resistance in coastal waters.
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.
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.

[Microplastic-Induced Alterations to Antibiotic Resistance Genes in Seawater].
Microplastics added to seawater were found to increase the diversity and abundance of antibiotic resistance genes (ARGs) over a 49-day period, with different plastics having different effects. This suggests that microplastics in coastal waters may contribute to the spread of drug-resistant bacteria, posing a risk to public health.
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.
Detection of antimicrobial resistance in Escherichia coli and Salmonella spp. Originated from cultivated oysters and estuarine waters
This study detected antimicrobial-resistant bacteria in oysters and estuarine waters, raising concerns about how aquatic environments serve as reservoirs for antibiotic resistance that can reach humans through seafood consumption. The findings are relevant to microplastic research because microplastics are known to harbor and concentrate antibiotic resistance genes on their surfaces.
Microplastics as Vectors of Antimicrobial Resistance in Aquatic Systems
This doctoral thesis investigated microplastics as vectors for antimicrobial resistance through in vitro, in situ, and in vivo experiments, examining the Plastisphere as a unique niche that may enrich antimicrobial-resistant pathogens beyond what bulk water concentrations would predict.
Microplastics in marine pollution: Oceanic hitchhikers for the global dissemination of antimicrobial-resistant bacteria
This review examines how marine microplastics serve as surfaces for biofilm formation by bacteria, including carbapenem-resistant strains, enabling the global dissemination of antimicrobial-resistant bacteria through ocean currents. The authors highlight the plastisphere as an understudied vector for spreading antibiotic resistance genes across marine environments.
The nexus of microplastics, food and antimicrobial resistance in the context of aquatic environment: Interdisciplinary linkages of pathways
This review examines how microplastics in aquatic environments serve as surfaces where bacteria can grow, share antibiotic resistance genes, and then enter the food chain through contaminated seafood. The combination of microplastic pollution and antimicrobial resistance creates a compounding threat, as resistant bacteria riding on plastic particles can survive water treatment and reach humans. The authors call for interdisciplinary research connecting environmental science and public health to address this growing risk.
From wastewater discharge to the beach: Survival of human pathogens bound to microplastics during transfer through the freshwater-marine continuum
Researchers investigated how human pathogens survive on microplastic surfaces as they travel from wastewater treatment plants through freshwater into marine environments. They found that the biofilm environment on plastic surfaces helped bacteria like E. coli and Enterococcus faecalis persist longer during transitions between water types compared to bacteria in the surrounding water. The study suggests that microplastics may facilitate the environmental spread of pathogens by providing a protective habitat during transport.
Bacterial pathogen assemblages on microplastic biofilms in coastal waters
Researchers incubated different types of microplastics in coastal waters for 21 days and analyzed the bacterial communities that colonized their surfaces. They found that while overall pathogen abundance was low, microplastic biofilms hosted a diverse array of potentially harmful bacteria whose composition varied by polymer type and water location. The study suggests that microplastics in coastal waters can serve as floating platforms for disease-causing microorganisms.

Microplastics accumulate priority antibiotic-resistant pathogens: Evidence from the riverine plastisphere
Researchers placed microplastics in river water and found they accumulated more antibiotic-resistant bacteria than natural sand particles, including dangerous pathogens like E. coli and Klebsiella. Most of the bacteria isolated from the plastic surfaces were multi-drug resistant and carried virulence traits like biofilm formation. This suggests microplastics in waterways may act as rafts for spreading antibiotic resistance through the environment.
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.
