Researchers used glacier-fed microcosm experiments to examine the combined effects of ciprofloxacin and microplastics on alpine spring water microbial communities, finding that the antibiotic caused significant community disruption while microplastics provided additional conditions favouring antibiotic-resistant biofilm formation.
Impact of sulfamethoxazole on a riverine microbiome
Scientists studied how the antibiotic sulfamethoxazole affects the microbial community in a river, finding that even low concentrations shifted the balance of bacteria and promoted antibiotic resistance genes. This is relevant to the microplastic field because both antibiotics and microplastics promote antibiotic resistance when they co-occur in aquatic environments.
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.
Dissemination Of Antibiotic Resistance Via Wastewater And Surface Water
This review examined how antibiotic-resistant bacteria spread through wastewater and surface water, noting that microplastics in wastewater can carry resistant bacteria into the environment. Antibiotic resistance is a growing public health crisis, and plastic pollution is one pathway accelerating its spread in waterways.
An Overview of the Impact of Pharmaceuticals on Aquatic Microbial Communities
This review provides an overview of how pharmaceutical pollutants in aquatic environments affect microbial communities, including biofilms in natural water systems. Researchers found that even at low environmental concentrations, pharmaceuticals can alter biofilm function and increase antimicrobial tolerance in bacteria. The study highlights the need for more research on how emerging pharmaceutical pollutants may contribute to antibiotic resistance and associated public health risks.
Antimicrobial 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.
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.
Occurrence of Antibiotic Resistance in Lotic Ecosystems
This review examines the occurrence and spread of antibiotic resistance genes and antibiotic-resistant bacteria in lotic (flowing water) ecosystems, analyzing how rivers and streams serve as reservoirs and conduits for the environmental dissemination of antibiotic resistance. Researchers synthesized evidence showing that agricultural runoff, wastewater discharge, and hospital effluents are major contributors to resistance gene loads in freshwater systems.
Antibiotic resistance fate in the full-scale drinking water and municipal wastewater treatment processes: A review
This review examines how antibiotic-resistant bacteria and resistance genes move through drinking water and wastewater treatment processes, finding that conventional treatment does not fully eliminate resistance. Microplastics in water systems act as surfaces that harbor and potentially transfer antibiotic resistance genes, making microplastic removal from water treatment an important co-benefit for antibiotic resistance management.
Holistic assessment of chemical and biological pollutants in a Mediterranean wastewater effluent-dominated stream: Interactions and ecological impacts
Researchers conducted a comprehensive assessment of pollution downstream from a wastewater treatment plant discharge into a Mediterranean river in Spain. They found elevated levels of pharmaceuticals, metals, microplastics, PFAS chemicals, and antibiotic resistance genes below the discharge point, though some recovery occurred within about 500 meters downstream. The study demonstrates that even treated wastewater significantly alters river water quality and microbial communities, highlighting the need for improved treatment technologies.
Microplastics and Antibiotics in Aquatic Environments: A Review of Their Interactions and Ecotoxicological Implications
This review examines how microplastics and antibiotics interact when they meet in water, and what that means for ecosystems and health. Antibiotics can attach to microplastic surfaces through chemical bonds, and the microplastics can then carry these drugs through the environment, potentially spreading antibiotic-resistant bacteria. While the combined threat to fish and other aquatic life needs more study, the findings raise concerns about how microplastics help move antibiotic resistance through water systems.
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.
