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.
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.

Assessment of Emerging Pathogens and Antibiotic Resistance Genes in the Biofilm of Microplastics Incubated Under a Wastewater Discharge Simulation
Researchers incubated common plastic types in flowing water that simulated wastewater discharge conditions for 10 weeks and studied the bacteria that colonized the plastic surfaces. They found that microplastics exposed to treated wastewater developed distinct bacterial communities compared to those in clean river water, including emerging pathogens and antibiotic resistance genes. The study suggests that microplastics in waterways receiving wastewater may serve as mobile platforms for spreading harmful bacteria and antibiotic resistance in the environment.
Biofilm-associated microplastic contamination in rural soil and water: emerging hazards to ecosystems
Researchers found significant microplastic contamination in soil and water near rural dumpsites in areas with poor waste management, with polystyrene and PET being the most common plastic types. The microplastic surfaces were colonized by bacteria that showed resistance to the antibiotic streptomycin, highlighting a dual threat of chemical pollution and drug resistance. These findings show that unregulated rural waste disposal creates hotspots where microplastics and antibiotic-resistant bacteria can enter local water supplies.
Impact 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.
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.
Microplastics in urban water cycles: Looking for a more scientific approach for sampling and characterization in wastewater and drinking water treatment plants
Researchers monitored microplastics in urban water cycles across three drinking water plants and two wastewater treatment plants using a self-designed large-volume sampler that collected up to 1,000 liters per sample. Raw drinking water and wastewater contained 2 or more microplastic particles per liter, highlighting contamination across the urban water system.
Contribution of microplastic particles to the spread of resistances and pathogenic bacteria in treated wastewaters

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.
