ClearSelective 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.
Microplastics can selectively enrich intracellular and extracellular antibiotic resistant genes and shape different microbial communities in aquatic systems
Researchers examined how microplastics of different types selectively capture antibiotic resistance genes and shape microbial communities in aquatic systems. They found that microplastics enriched both intracellular and extracellular antibiotic resistance genes, with the enrichment patterns varying by plastic type. The study suggests that microplastics may serve as hotspots for the spread of antimicrobial resistance in wastewater and natural water environments.
Do microplastic biofilms promote the evolution and co-selection of antibiotic and metal resistance genes and their associations with bacterial communities under antibiotic and metal pressures?
Researchers investigated whether microplastic biofilms promote the evolution and co-selection of antibiotic and metal resistance genes compared to natural substrates, examining how combined antibiotic and metal pressures shape resistant bacterial communities on plastic surfaces.
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.
Investigating Biofilms: Advanced Methods for Comprehending Microbial Behavior and Antibiotic Resistance
This review summarizes recent advances in biofilm research, focusing on how communities of microorganisms form protective layers on surfaces and become resistant to antibiotics. The sticky matrix that holds biofilms together plays a key role in spreading antibiotic resistance genes between bacteria. While not directly about microplastics, the findings are relevant because microplastics in the environment serve as surfaces where these resistant biofilms can form and spread.
Selective enrichment of antibiotic resistome and bacterial pathogens by aquatic microplastics
This review found that microplastics in aquatic environments selectively enrich antibiotic-resistant bacteria, resistance genes, and bacterial pathogens in their biofilms, making plastic debris a potential vector for spreading antimicrobial resistance.
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.
Selective enrichment of bacteria and antibiotic resistance genes in microplastic biofilms and their potential hazards in coral reef ecosystems
Researchers found that microplastic surfaces in coral reef waters selectively collect bacteria carrying antibiotic resistance genes, with the concentration of resistant bacteria linked to antibiotic levels in the surrounding water. The bacterial communities on microplastics were enriched for disease-related pathways compared to the surrounding seawater. This means microplastics in marine environments could serve as vehicles for spreading drug-resistant infections, posing risks to both coral ecosystems and human health.
DeterminingAntimicrobial Resistance in the Plastisphere:Lower Risks of Nonbiodegradable vs Higher Risks of Biodegradable Microplastics
Researchers determined the prevalence and diversity of antimicrobial resistance genes in the plastisphere (biofilm on microplastics) compared to surrounding water and sediment, finding that non-biodegradable plastics hosted distinct resistance gene profiles with lower overall resistance risk than biodegradable plastic surfaces.
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.
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.
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.
