ClearCorrelation appraisal of antibiotic resistance with fecal, metal and microplastic contamination in a tropical Indian river, lakes and sewage
Researchers sampled water from Indian urban rivers, lakes, and sewage plants and found that antibiotic-resistant bacteria correlated with fecal contamination and microplastic presence, especially for certain antibiotics, while fluoroquinolone resistance appeared more linked to seasonal temperature. The study suggests microplastics may help spread antibiotic resistance in urban waterways, adding a new dimension to concerns about plastic pollution.
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.
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 Pose an Elevated Antimicrobial Resistance Risk Than Natural Surfaces via a Systematic Comparative Study of Surface Biofilms in Rivers
A systematic comparison of biofilms on microplastics versus natural surfaces like wood and rock in rivers found that microplastics harbor 10 times more antibiotic-resistant bacteria. The microplastics' water-repelling surface properties encourage the growth of drug-resistant pathogens and the accumulation of resistance genes. This finding is concerning because microplastics flowing through waterways could be spreading antibiotic resistance, which is a major threat to global public health.

Researchers measured microplastic concentrations at point and non-point source locations in Colombo, Sri Lanka, across different seasons. Microplastics were found throughout the surface water network, with concentrations varying by season and location type. The study provides valuable baseline data for a poorly studied region and highlights urban water bodies as major microplastic sources.
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.
Seasonal Dynamics of Microplastic Pollution in the River Ganga: A Case Study from Bihar
Researchers sampled microplastics at three locations along the Ganga River in Bihar, India, comparing concentrations before and after the monsoon season. Pre-monsoon levels averaged 1,045 particles per sample versus 624 post-monsoon, with higher dry-season concentrations attributed to reduced river flow and concentrated human activity near the riverbanks.
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.
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.
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.

Regulation of ARGs abundance by biofilm colonization on microplastics under selective pressure of antibiotics in river water environment
Researchers investigated how biofilms forming on microplastics in river water affect the spread of antibiotic resistance genes under antibiotic pressure. They found that the presence of antibiotics accelerated biofilm colonization on microplastic surfaces and significantly increased the abundance of resistance genes compared to conditions without antibiotics. The study suggests that microplastics in waterways may serve as hotspots for the development and transfer of antibiotic resistance.
