ClearAntimicrobial Resistance Development Pathways in Surface Waters and Public Health Implications
Researchers evaluated the pathways through which antibiotic-resistant bacteria develop and spread in surface waters, identifying healthcare facilities, wastewater, agricultural runoff, and wildlife as major vehicles. The study found that antibiotic residues, heavy metals, and even climate change drive the emergence of resistance in aquatic environments. The findings highlight that surface water contamination poses a growing public health threat, particularly for food and animal handlers who face higher exposure risk.
Aeromonas spp. in Freshwater Bodies: Antimicrobial Resistance and Biofilm Assembly
Researchers isolated Aeromonas bacteria from freshwater sources and examined their ability to resist antibiotics and form protective biofilms. They found that many strains carried multiple antibiotic resistance genes and could form biofilms that made them harder to eliminate.

Correlation 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.
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.
Knowledge gaps in the assessment of antimicrobial resistance in surface waters
This review identifies knowledge gaps in assessing antimicrobial resistance in surface waters, highlighting uncertainties about the selection pressure from antibiotics and heavy metals and the impact on aquatic organisms and human health.
Profiling of Antibiotic Residues in Surface Water of River Yamuna Stretch Passing through Delhi, India
Researchers detected antibiotic residues in the River Yamuna passing through Delhi, with ofloxacin found at the highest concentration (145 ng/mL), and observed significant seasonal and spatial variation linked to hospital discharge, drug manufacturing, and agricultural runoff.
Abundance and Antimicrobial Resistance of Three Bacterial Species along a Complete Wastewater Pathway
A year-long study of a Swedish wastewater pathway found that antibiotic-resistant bacteria were most abundant in hospital wastewater and that resistance profiles mirrored local antibiotic consumption. Wastewater treatment plants also process microplastics, and understanding how bacteria move through these systems is relevant to the plastisphere's role in spreading resistance.
Antibiotic resistance genes in treated wastewater and in the receiving water bodies: A pan-European survey of urban settings
Researchers surveyed 16 wastewater treatment plants across ten European countries and found that antibiotic resistance genes — DNA instructions that help bacteria survive antibiotics — are consistently released into rivers receiving treated wastewater. The study found that plants with more biological treatment steps had lower levels of these genes, suggesting that upgrading treatment infrastructure could reduce the spread of antibiotic resistance in the environment.
Antibiotic and Non-Antibiotic Determinants of Antimicrobial Resistance: Insights from Water Ecosystems
This review explains how non-antibiotic pollutants like heavy metals, biocides, and microplastics are contributing to antibiotic resistance in water systems, beyond the well-known problem of antibiotic overuse. Wastewater treatment plants are hotspots where these pollutants interact with bacteria, promoting the spread of resistance genes through mobile genetic elements. The findings are concerning for human health because drug-resistant bacteria from water environments can ultimately reach people through drinking water and food.
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.
The nexus of microplastics, food and antimicrobial resistance in the context of aquatic environment: Interdisciplinary linkages of pathways
This review examines how microplastics in aquatic environments serve as surfaces where bacteria can grow, share antibiotic resistance genes, and then enter the food chain through contaminated seafood. The combination of microplastic pollution and antimicrobial resistance creates a compounding threat, as resistant bacteria riding on plastic particles can survive water treatment and reach humans. The authors call for interdisciplinary research connecting environmental science and public health to address this growing risk.
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.
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.
