ClearImpact of Urbanization on Antibiotic Resistome in Different Microplastics: Evidence from a Large-Scale Whole River Analysis
Researchers conducted a large-scale river survey across urbanization gradients and characterized antibiotic resistance genes on microplastics from each zone, finding that urbanization level strongly predicted the diversity and abundance of resistance genes on plastic surfaces.
Evaluating the role of microplastics and wastewater in shaping Vibrio spp. and antibiotic resistance gene abundance in urban freshwaters
Researchers sampled water and microplastic biofilms from urban South African rivers and found that microplastics disproportionately enriched Vibrio spp. and tetracycline resistance genes relative to the surrounding water, suggesting microplastics selectively concentrate pathogens and antibiotic resistance genes.
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.
Metagenomic insights into environmental risk of field microplastics in an urban river
Metagenomic analysis of microplastics sampled along an urban river watershed revealed that MP-associated microbial communities carried antibiotic resistance genes and virulence factors at higher levels than surrounding water, with composition shifting along the river gradient. The findings confirm microplastics as environmental vectors for spreading antimicrobial resistance.
Microplastics and antibiotic-resistant bacteria contamination in a river of central Italy
Researchers sampled a river in central Italy for both microplastics and antibiotic-resistant bacteria, finding polyethylene as the dominant polymer at over 60 percent of detected plastic debris. The study found a high rate of multidrug resistance among isolated bacteria, suggesting that the co-occurrence of microplastics and resistant bacteria in river water may amplify the environmental spread of antimicrobial resistance.
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.
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.
Contribution of microplastic particles to the spread of resistances and pathogenic bacteria in treated wastewaters
Researchers studied microplastic particles collected from treated wastewater effluents and found that MPs harbored significantly higher loads of antibiotic resistance genes and pathogenic bacteria compared to surrounding water, suggesting MPs facilitate their environmental spread.
Size effects of microplastics on antibiotic resistome and core microbiome in an urban river
Scientists found that microplastics in an urban river serve as platforms for antibiotic-resistant bacteria and dangerous pathogens including Pseudomonas aeruginosa, Mycobacterium tuberculosis, and Legionella pneumophila. Larger microplastic particles harbored more antibiotic resistance genes, and the concentrations of these genes were much higher on plastic surfaces than in the surrounding water. This research raises concerns that microplastics in waterways could spread drug-resistant infections by providing a surface where dangerous bacteria thrive and share resistance genes.
Metagenomic insights into ecological risk of antibiotic resistome and mobilome in riverine plastisphere under impact of urbanization
This study used advanced genetic sequencing to examine antibiotic resistance genes on microplastics found in an urban river. Microplastics harbored more antibiotic resistance genes and mobile genetic elements than natural materials like rocks and wood, and the problem was worse in more urbanized areas. The findings suggest that microplastics in waterways can act as hotspots for spreading antibiotic resistance, which is a growing public health threat.
Watershed urbanization enhances the enrichment of pathogenic bacteria and antibiotic resistance genes on microplastics in the water environment
Researchers compared microplastic biofilm communities (the plastisphere) across watersheds with different levels of urbanization, finding that higher urbanization enriched pathogenic bacteria and antibiotic resistance genes on plastic surfaces in waterways. The study suggests that urban runoff substantially elevates the health risk posed by microplastics as vectors of pathogens and antimicrobial resistance.
Quantifying health risks of plastisphere antibiotic resistome and deciphering driving mechanisms in an urbanizing watershed
This study measured the health risks posed by antibiotic resistance genes found on microplastic surfaces in a watershed affected by urbanization. Polyethylene microplastics carried the highest risk, and urban development increased the danger by promoting the spread of resistance genes among bacteria living on plastic surfaces. The findings show that microplastics in waterways act as vehicles for antibiotic resistance, which could make infections harder to treat in communities downstream.
Susceptibility of a peri-urban water supply and sanitation system to selected emerging micropollutants
Researchers tested seven peri-urban water quality monitoring sites for emerging micropollutants including microplastics and antibiotic-resistant bacteria, finding that while microplastics were absent from raw and treated tap water, they were present in raw sewage, raising environmental concerns about wastewater system discharges.
Distinct profile of bacterial community and antibiotic resistance genes on microplastics in Ganjiang River at the watershed level
Researchers investigated microplastic pollution and associated bacterial communities, human pathogenic bacteria, and antibiotic resistance genes across the Ganjiang River watershed. They found microplastics were widely distributed with an average of 407 particles per cubic meter, and that microplastic surfaces harbored significantly higher bacterial diversity and more antibiotic resistance genes than surrounding water or sediment.
Evidence of selective enrichment of bacterial assemblages and antibiotic resistant genes by microplastics in urban rivers
Researchers sampled microplastics from two urban rivers in China and found that the bacterial communities colonizing plastic particles were distinctly different from those in the surrounding water. The microplastic-associated bacteria had lower diversity but higher proportions of biofilm-forming species and functions linked to human disease. Notably, the study found that microplastics selectively enriched antibiotic resistance genes, raising concerns about plastics serving as reservoirs for drug-resistant bacteria.
[Microplastics-Induced Shifts of Diversity and Abundance of Antibiotic Resistance Genes in River Water].
This Chinese study used high-throughput quantitative PCR to measure how different microplastic types affect the diversity and abundance of antibiotic resistance genes in river water. Polystyrene and polyethylene microplastics both increased the overall abundance of resistance genes, supporting concerns that microplastics act as reservoirs and spreaders of antibiotic resistance in freshwater systems.
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.
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.
Selectively enrichment of antibiotics and ARGs by microplastics in river, estuary and marine waters
Researchers investigated how microplastics interact with antibiotics and antibiotic resistance genes across river, estuary, and marine environments of varying salinity. They found that microplastics can concentrate both antibiotics and antibiotic resistance genes from surrounding water, with this enrichment effect being strongest in freshwater and decreasing as salinity increases. The study raises concerns that microplastics may serve as vehicles for spreading antibiotic resistance in aquatic ecosystems.
