ClearMicroplastic pollution increases gene exchange in aquatic ecosystems
Researchers found that microplastics in aquatic environments serve as surfaces where bacteria form biofilms and exchange genes at higher rates than free-living bacteria. The study demonstrated increased transfer of antibiotic resistance genes among a wide range of bacterial species growing on microplastic particles. The findings suggest that microplastic pollution could accelerate the spread of antibiotic resistance in waterways, posing a potential hazard to both ecosystems and human health.
Conjugative antibiotic-resistant plasmids promote bacterial colonization of microplastics in water environments

Researchers investigated whether microplastics in wastewater treatment plants can accumulate and spread antibiotic resistance genes. They found that bacteria growing on microplastic surfaces in treatment tanks harbored antibiotic resistance genes and transferred them at higher rates than bacteria in the surrounding water. This suggests microplastics in wastewater systems may serve as hotspots for spreading antibiotic resistance, posing potential risks to both ecosystems and human health.

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.
Microplastics mediates the spread of antimicrobial resistance plasmids via modulating conjugal gene expression
This study found that four common types of microplastics can increase the spread of antibiotic resistance genes between bacteria by up to 200-fold. The microplastics activated stress-response genes in bacteria that promote the sharing of resistance-carrying DNA. This links two major public health threats, showing that microplastic pollution could make antibiotic-resistant infections more common and harder to treat.
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.

The findings raise concerns that microplastic pollution may be contributing to the growing global challenge of antibiotic resistance.
Evidence of interspecific plasmid uptake by pathogenic strains of Klebsiella isolated from microplastic pollution on public beaches
Researchers collected microplastic beads from public beaches and found them colonized by pathogenic strains of Klebsiella bacteria carrying antimicrobial resistance genes. They demonstrated that these bacteria could take up plasmids from other species, potentially spreading antibiotic resistance. The findings suggest that microplastics on beaches may serve as hotspots where dangerous bacteria exchange genetic material that makes them harder to treat.
Microplastic biofilms promote the horizontal transfer of antibiotic resistance genes in estuarine environments
Researchers compared how effectively antibiotic resistance genes transfer between bacteria floating freely in water versus bacteria living in biofilms on microplastic surfaces. They found that microplastic biofilms significantly enhanced the transfer of resistance genes compared to free-floating bacteria, with factors like extracellular DNA and cell membrane permeability playing key roles. The study suggests that microplastics in estuaries may act as hotspots for spreading antibiotic resistance in the environment.

Researchers examined how microplastic surfaces act as vectors for spreading antibiotic resistance genes in wastewater treatment systems.

Underestimated Risks of Microplastics on the Environmental Spread of Antibiotic Resistance Genes
Researchers highlight how microplastics in aquatic environments can accelerate the spread of antibiotic resistance genes, a risk that current assessment methods may significantly underestimate. Biofilms that form on microplastic surfaces create conditions where bacteria are in close contact, facilitating the transfer of resistance genes between species. The study argues that standard microplastic detection methods miss many small particles, meaning the true scope of this resistance-spreading pathway is likely much larger than reported.
