ClearDetection of antimicrobial resistance in Escherichia coli and Salmonella spp. Originated from cultivated oysters and estuarine waters
This study detected antimicrobial-resistant bacteria in oysters and estuarine waters, raising concerns about how aquatic environments serve as reservoirs for antibiotic resistance that can reach humans through seafood consumption. The findings are relevant to microplastic research because microplastics are known to harbor and concentrate antibiotic resistance genes on their surfaces.

Increasing microplastics pollution: An emerging vector for potentially pathogenic bacteria in the environment
Researchers collected microplastics from a river basin in Turkey and found that disease-causing bacteria, including Salmonella, E. coli, and Staphylococcus, readily form colonies on plastic particle surfaces. This means microplastics floating in water can act as tiny rafts carrying harmful bacteria, potentially increasing infection risks when contaminated water is used for drinking or recreation.
Emerging Issues on Antibiotic-Resistant Bacteria Colonizing Plastic Waste in Aquatic Ecosystems
Researchers found antibiotic-resistant bacteria colonizing plastic waste submerged in an inland water body, including species related to human pathogens like Klebsiella. All isolated bacteria showed high resistance to multiple antibiotics, and they carried numerous antibiotic resistance genes. This is concerning because plastic waste in waterways can serve as a platform for drug-resistant bacteria to multiply and potentially spread to humans through contaminated water.

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.
Investigating microplastic occurrences in coastal surface seawaters and their potential role as transport vectors for multidrug-resistant E. coli
Researchers investigated microplastic occurrences in coastal surface seawaters and examined whether microplastics serve as transport vectors for multidrug-resistant E. coli, addressing a gap in comparable long-term data on microplastic contamination in aquatic systems. The thesis found that microplastics in coastal environments can carry antibiotic-resistant bacteria, raising concerns about their role in spreading antimicrobial resistance.
Potential of waterbodies as a reservoir ofEscherichia colipathogens and the spread of antibiotic resistance in the Indonesian aquatic environment
This review analyzes the factors driving the spread of pathogenic Escherichia coli and antibiotic-resistant bacteria in Indonesian aquatic environments, including antibiotic misuse, inadequate waste treatment, and poor industrial waste management. Indonesian rivers serve as vectors for both pathogenic E. coli and antimicrobial resistance genes, posing significant public health risks.
Comparison of the Antibiotic Resistance of Escherichia coli Populations from Water and Biofilm in River Environments
Researchers compared antibiotic resistance in E. coli populations from river water versus sediment and biofilm samples at locations upstream and downstream of urban areas in Austria. They found that biofilm and sediment environments harbored bacteria with higher rates of antibiotic resistance compared to the water column. The study suggests that river biofilms may serve as reservoirs for antibiotic-resistant bacteria, with implications for how pollutants including microplastics interact with microbial communities.
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.
Comparison of Antibiotic Resistance of Escherichia coli Populations from Water or Sediment in Rivers Environments
This study compared antibiotic-resistant E. coli in river water and sediment, examining how bacteria form biofilms and stabilize resistance in these environments.

Impact 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.
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.
Changes in microplastic-associated bacterial communities along a salinity gradient in Central Anatolian lakes of Türkiye
Researchers examined bacterial communities growing on microplastic surfaces across 11 Turkish lakes spanning a wide range of salinity levels.

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.
Enrichment of Antibiotic Resistance Genes on Plastic Waste in Aquatic Ecosystems, Aquatic Animals, and Fishery Products
This review examines how plastic waste in water creates surfaces where antibiotic-resistant bacteria thrive and share resistance genes with each other. Microplastics in rivers, oceans, and fish farms were consistently found to harbor more antibiotic resistance genes than natural materials like rocks or sand. Since fish and shellfish can accumulate these microplastic-associated resistant bacteria, there is a risk that drug-resistant infections could reach humans through the seafood supply chain.
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.
