ClearImpact of wastewater treatment plant effluent discharge on the antibiotic resistome in downstream aquatic environments: a mini review
This review summarizes how wastewater treatment plants release antibiotic-resistant bacteria and resistance genes into rivers and lakes through their treated water. Current treatment processes cannot fully remove these resistance factors, allowing them to spread in downstream water bodies and potentially reach humans through drinking water and the food chain. The review is relevant to microplastics research because microplastics in wastewater can serve as surfaces where resistant bacteria grow and spread.
The Role of Wastewater Treatment Plants in Dissemination of Antibiotic Resistance: Source, Measurement, Removal and Risk Assessment
This review examines how wastewater treatment plants handle antibiotic-resistant bacteria and their resistance genes, finding that current treatment processes do not fully remove them. Different levels of treatment show varying removal rates, and resistant bacteria can still be found in treated water released into the environment. While not directly about microplastics, the findings are relevant because microplastics in wastewater can carry antibiotic-resistant bacteria into waterways.
Microplastics and Antibiotic Resistance: The Magnitude of the Problem and the Emerging Role of Hospital Wastewater
This review examines how microplastics in water can carry antibiotic-resistant bacteria and spread resistance genes, especially through hospital wastewater. Microplastics provide a surface where bacteria easily form colonies and share resistance genes, creating a potential threat to human health. The authors call for better wastewater management to reduce this emerging risk.

On the Generation, Impact and Removal of Antibiotic Resistance in the Water Environment
This review explains how antibiotic resistance develops and spreads through water environments — including rivers, groundwater, and wastewater. The findings are relevant to microplastics because plastic particles in water are known to accumulate antibiotic-resistant bacteria, potentially accelerating the spread of drug resistance through aquatic systems.
Water and sanitation: an essential battlefront in the war on antimicrobial resistance
This review examines the role of water and sanitation infrastructure in combating antimicrobial resistance, identifying wastewater and contaminated water as key transmission routes for resistant bacteria and resistance genes. While focused on AMR broadly, the study notes that microplastics in water systems can serve as substrates for biofilm formation and may facilitate the spread of antimicrobial resistance in aquatic environments.
Dissemination Of Antibiotic Resistance Via Wastewater And Surface Water
This review examined how antibiotic-resistant bacteria spread through wastewater and surface water, noting that microplastics in wastewater can carry resistant bacteria into the environment. Antibiotic resistance is a growing public health crisis, and plastic pollution is one pathway accelerating its spread in waterways.
Research progress on the origin, fate, impacts and harm of microplastics and antibiotic resistance genes in wastewater treatment plants
This review explores how microplastics and antibiotic resistance genes interact in wastewater treatment plants, where they can survive treatment and enter the environment together. The concern for human health is that these contaminants can travel through the food chain, potentially increasing illness from antibiotic-resistant infections.
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.
Growth and prevalence of antibiotic-resistant bacteria in microplastic biofilm from wastewater treatment plant effluents
Researchers studied antibiotic-resistant bacteria growing in biofilms on microplastic surfaces in wastewater treatment plant effluent. The study found that microplastic biofilms accumulated antibiotic-resistant bacteria including Pseudomonas, Aeromonas, and Bacillus, and that these biofilms harbored higher concentrations of resistance genes compared to surrounding water, suggesting microplastics may serve as reservoirs for antibiotic resistance.
Characterization of microplastics and their interaction with antibiotics in wastewater
Researchers characterized microplastics in wastewater and investigated their interactions with antibiotics, examining how microplastic surfaces adsorb antibiotic compounds and the implications for antibiotic transport and dissemination in wastewater treatment 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.
Fragmented Microplastics Synergize with Biological Treatment To Potentiate Antibiotic Resistance Dissemination during Sewage Treatment
Researchers used metagenomic sequencing and high-throughput qPCR across a full sewage treatment chain to show that fragmented microplastics preferentially concentrate clinically relevant antibiotic resistance genes, with MP-bound genes contributing up to 43% of intracellular resistance genes detected in treated effluent, and Acinetobacter emerging as a key resistance indicator.
Antibiotic resistance genes and virulence factors in the plastisphere in wastewater treatment plant effluent: Health risk quantification and driving mechanism interpretation
Researchers found that microplastics in treated wastewater carry significantly more disease-causing bacteria, antibiotic resistance genes, and virulence factors on their surfaces compared to the surrounding water. This means microplastics released from wastewater treatment plants into rivers and lakes could spread antibiotic-resistant infections, posing a direct risk to communities that rely on these water sources.
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.
Emerging Antibiotic Resistance Genes in the Aquatic Ecosystems: a Review
A review of 30 studies found antibiotic resistance genes (ARGs) widely distributed across aquatic ecosystems — in surface water, groundwater, wastewater, and notably on plastic and microplastic debris in these environments. Microplastics appear to provide favorable surfaces for the growth and exchange of resistant bacteria, making plastic pollution a potential vector for spreading antibiotic resistance. The findings highlight an understudied intersection between microplastic contamination and the global antibiotic resistance crisis.
Microplastic 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.

The findings raise concerns that microplastic pollution may be contributing to the growing global challenge of antibiotic resistance.
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.
Microplastic biofilm, associated pathogen and antimicrobial resistance dynamics through a wastewater treatment process incorporating a constructed wetland
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.
Abundance and Antimicrobial Resistance of Three Bacterial Species along a Complete Wastewater Pathway
