This review examined antimicrobial resistance in exploited estuaries, identifying overlooked environmental contaminants including antibiotics, heavy metals, and biocides as drivers of resistance gene spread in estuarine microbiomes with implications for human health and food safety.
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.
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. Microplastics in aquatic environments are known to promote biofilm formation and concentrate antibiotic resistance genes, amplifying this public health concern.
The problem of contamination of aquatic ecosystems with antibiotics (a review)
This review examines the contamination of aquatic ecosystems by antibiotics, synthesizing global data on risks associated with antibiotic presence in ocean and freshwater environments, including effects on aquatic organisms and the promotion of antibiotic resistance. The authors assess quantitative and qualitative contamination using bivalves as bioindicators and evaluate the spread of resistance genes through aquatic biocenoses.
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.
Monitoring water contamination through shellfish: A systematic review of biomarkers, species selection, and host response.
Across 20 studies spanning 14 countries, shellfish proved highly sensitive to minor environmental changes, with 26 species and 35 effect biomarkers identified, supporting their use as reliable bioindicators of water quality, though standardized monitoring protocols are still needed.
Bivalves Diversity and Abundance in the Coastal Waters: An Environmental Pollution Monitoring Measure
Researchers assessed bivalve species diversity, abundance, and water physicochemical factors at three sites in Banyuurip Village, Indonesia, using the assemblage as a bioindicator of water quality impacts from industrial and household waste pollution.
Metagenomic insights into environmental risk of field microplastics in an urban river
Metagenomic analysis of microplastics sampled along an urban river watershed revealed that MP-associated microbial communities carried antibiotic resistance genes and virulence factors at higher levels than surrounding water, with composition shifting along the river gradient. The findings confirm microplastics as environmental vectors for spreading antimicrobial resistance.
An Overview of Antibiotics as Emerging Contaminants: Occurrence in Bivalves as Biomonitoring Organisms
Researchers reviewed the occurrence of antibiotic residues in bivalve mollusks used as biomonitoring organisms across European, American, and Asian coastlines. They found that macrolides, sulfonamides, and quinolones were the most frequently detected antibiotic classes, though the health risk from consuming contaminated bivalves was generally assessed as negligible. The study emphasizes the importance of continued monitoring to prevent the development of antimicrobial resistance from environmental antibiotic contamination.
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.
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 genes might serve as new indicators for wastewater contamination of coastal waters: Spatial distribution and source apportionment of antibiotic resistance genes in a coastal bay
Researchers found that antibiotic resistance genes (ARGs) — DNA sequences that make bacteria immune to antibiotics — were significantly elevated near wastewater discharge points in a Chinese coastal bay, suggesting ARGs could serve as sensitive new indicators of sewage contamination in marine waters. Wastewater treatment plants and polluted rivers were identified as the primary sources driving ARG distribution patterns.
Antibiotic resistance profiles of Escherichia coli isolated from the floating islands and water of Çat Dam Lake, Adiyaman, Turkey
Antibiotic-resistant E. coli bacteria were isolated from water samples and floating islands in a Turkish dam lake, with resistance profiles linked to agricultural runoff and human waste inputs.
