ClearMicroplastic biofilms in water treatment systems: Fate and risks of pathogenic bacteria, antibiotic-resistant bacteria, and antibiotic resistance genes
This review examines how microplastics in drinking water and wastewater treatment plants develop biofilms that harbor dangerous bacteria and antibiotic resistance genes. The biofilm-coated microplastics can protect pathogens from disinfection processes, allowing them to survive treatment and potentially reach tap water. This raises concerns about microplastics serving as vehicles for antibiotic-resistant bacteria in our water supply.
Microplastic mediated bacterial contamination in water distribution systems as an emerging public health threat
This scoping review examines how microplastics enter and move through water distribution networks, their role as surfaces for bacterial attachment, and the mechanisms by which they amplify public health threats from waterborne pathogens in drinking water systems.
Microplastics in fresh- and wastewater are potential contributors to antibiotic resistance - A minireview
Researchers reviewed the link between microplastic pollution and the spread of antibiotic resistance in freshwater environments, finding that microplastic surfaces host unique bacterial communities enriched in antibiotic-resistant bacteria and the resistance genes they can share with other microbes. The close packing of bacteria in these plastic-surface biofilms may accelerate the spread of drug-resistant pathogens through drinking water sources, though the full health implications remain poorly understood.
Antibiotic resistance fate in the full-scale drinking water and municipal wastewater treatment processes: A review
This review examines how antibiotic-resistant bacteria and resistance genes move through drinking water and wastewater treatment processes, finding that conventional treatment does not fully eliminate resistance. Microplastics in water systems act as surfaces that harbor and potentially transfer antibiotic resistance genes, making microplastic removal from water treatment an important co-benefit for antibiotic resistance management.
Can microplastics and disinfectant resistance genes pose conceivable threats to water disinfection process?
This review examines how microplastics in water supplies interact with disinfection resistance genes (DRGs) in bacteria, creating a compounding threat to water safety. Microplastics provide surfaces where resistant bacteria can form biofilms and exchange resistance genes, and they can locally reduce the effective concentration of disinfectants — making standard water treatment less effective. The concern is that as both microplastic pollution and disinfectant use grow, we may be inadvertently breeding harder-to-kill pathogens in our drinking water systems.
Interactive impacts of microplastics and chlorine on biological stability and microbial community formation in stagnant water
Researchers found that microplastics in stagnant drinking water accelerated chlorine decay and promoted microbial regrowth, with microplastic-associated biofilms harboring opportunistic pathogens and shifting microbial community composition toward potentially harmful species.
Microplastic-associated pathogens and antimicrobial resistance in environment
This review examines how microplastics in the environment act as surfaces for disease-causing bacteria and antibiotic-resistant microbes to colonize and spread. Researchers found that microplastics can carry pathogens and facilitate the transfer of antimicrobial resistance genes between bacteria in water systems. The findings raise concerns that microplastic pollution may be contributing to the growing global challenge of antibiotic resistance.
Environmental Health and Safety Implications of the Interplay Between Microplastics and the Residing Biofilm
This review examines the two-way relationship between microplastics and biofilms, the communities of microorganisms that quickly colonize plastic surfaces in the environment. Biofilms on microplastics can harbor harmful bacteria, concentrate toxic chemicals, and help spread antibiotic resistance genes through water systems. Understanding this interplay is important for human health because these contaminated biofilm-coated microplastics can enter drinking water and food supplies.
Recent advances in the relationships between biofilms and microplastics in natural environments
This review summarizes how microorganisms form biofilms on the surface of microplastics in water, changing the particles' physical properties and helping to spread bacteria and genes across ecosystems. These biofilm-coated microplastics can carry harmful microbes into new environments, raising concerns about waterborne disease transmission and the effectiveness of current water treatment methods.
Biofilm formation on microplastics and interactions with antibiotics, antibiotic resistance genes and pathogens in aquatic environment
This review explains how microplastics in waterways develop bacterial biofilms on their surfaces that can harbor antibiotic-resistant bacteria and help spread antibiotic resistance genes to new environments. This is concerning for human health because these resistant microbes could eventually reach people through drinking water or seafood consumption.

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 in drinking water distribution systems: Occurrence, environmental behavior, and human health concerns
This review examines how microplastics move through drinking water distribution systems, from treatment plants all the way to household taps. Despite treatment efforts, microplastics persist in the water supply, with plastic pipes and fittings themselves contributing additional contamination. The tiny particles also serve as carriers for harmful bacteria and other pollutants, compounding the health risks of microplastic-contaminated drinking water.
Selective enrichment of bacterial pathogens by microplastic biofilm
Researchers incubated biofilms on microplastics and natural substrates in freshwater and found that microplastic surfaces selectively enriched bacterial pathogens and antibiotic resistance genes compared to rock and leaf surfaces. The study suggests that microplastics in waterways may serve as hotspots for harmful bacteria and contribute to the spread of antibiotic resistance in the environment.
The resistance change and stress response mechanisms of chlorine-resistant bacteria under microplastic stress in drinking water distribution system
Researchers found that microplastics in drinking water pipes can make chlorine-resistant bacteria even more dangerous by boosting their resistance to both antibiotics and disinfectants. Bacteria attached to microplastic surfaces changed their outer coatings and activated stress responses that increased their survival against water treatment chemicals. This is concerning because it means microplastics in water distribution systems could help create superbugs that standard water treatment cannot eliminate.
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.
Microplastics and chemical leachates from plastic pipes are associated with increased virulence and antimicrobial resistance potential of drinking water microbial communities
Researchers found that microplastics and chemical leachates released from polypropylene drinking water pipes can promote antimicrobial resistance and virulence in the microbial communities that form inside the pipes. Exposure to chlorination, heating, and freeze-thaw cycles accelerated microplastic generation and chemical leaching from the pipes. The findings suggest that plastic plumbing materials may be an underappreciated factor in drinking water safety.

This study tracked how microplastic-associated biofilms, pathogens, and antibiotic resistance genes changed through a wastewater treatment process that included a constructed wetland. While the treatment reduced some pathogens, certain antibiotic resistance genes persisted on microplastic surfaces even after treatment. This means microplastics leaving treatment plants could carry drug-resistant bacteria into rivers and lakes, potentially affecting downstream drinking water sources.
