ClearPotential 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.
Assessing antimicrobial and metal resistance genes in Escherichia coli from domestic groundwater supplies in rural Ireland
Researchers analyzed E. coli bacteria from private drinking wells in rural Ireland, finding that antibiotic resistance genes were present in 17% of isolates, likely arriving in groundwater via agricultural runoff rather than forming there. Importantly, no clear link was found between metal contamination and antibiotic resistance levels, suggesting livestock farming practices are the primary driver.
Escherichia coli Phylogenetic and Antimicrobial Pattern as an Indicator of Anthropogenic Impact on Threatened Freshwater Mussels
Researchers analyzed E. coli isolated from freshwater mussels (Margaritifera margaritifera and Potomida littoralis) in two Portuguese rivers with different levels of anthropogenic contamination, finding greater antibiotic resistance and more diverse phylogenetic profiles at the more contaminated site. The results suggest E. coli from freshwater mussels can serve as an indicator of antimicrobial resistance pressure from human activities.
Antibiotic Resistance Mediated by Escherichia coli in Kuwait Marine Environment as Revealed through Genomic Analysis
Researchers used genomic analysis to identify antibiotic resistance genes in Escherichia coli isolated from mollusks and coastal water samples in Kuwait's marine environment. The study found that Kuwait's coastal waters, vulnerable to sewage contamination from storm outlets and waste disposal, harbor E. coli carrying multiple antibiotic resistance gene elements including integrons and plasmids.
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.
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.
Detection of antimicrobial resistance in Escherichia coli and Salmonella spp. Originated from cultivated oysters and estuarine waters
This study detected antimicrobial-resistant bacteria in oysters and estuarine waters, raising concerns about how aquatic environments serve as reservoirs for antibiotic resistance that can reach humans through seafood consumption. The findings are relevant to microplastic research because microplastics are known to harbor and concentrate antibiotic resistance genes on their surfaces.
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.
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. The study highlights the role of freshwater environments as reservoirs for antibiotic-resistant bacteria that can potentially affect both animal and human health.
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.
Investigating microplastic occurrences in coastal surface seawaters and their potential role as transport vectors for multidrug-resistant E. coli
Researchers investigated microplastic occurrences in coastal surface seawaters and examined whether microplastics serve as transport vectors for multidrug-resistant E. coli, addressing a gap in comparable long-term data on microplastic contamination in aquatic systems. The thesis found that microplastics in coastal environments can carry antibiotic-resistant bacteria, raising concerns about their role in spreading antimicrobial resistance.
Microplastics as a novel facilitator for antimicrobial resistance: Effects of concentration, composition, and size on Escherichia coli multidrug resistance
This study examined how microplastics facilitate antimicrobial resistance by acting as a surface for the co-selection of resistant bacteria, finding that plastic surfaces enrich resistance genes and transfer-capable elements in aquatic environments.
Occurrence of EBSL and quinolone resistance genes among Escherichia coli and Klebsiella pneumoniae isolated from poultry, domestic pigs and environment in the Msimbazi River Basin in Tanzania
Researchers investigated the occurrence and distribution of extended-spectrum beta-lactamase (ESBL) and plasmid-mediated quinolone resistance genes in multi-drug-resistant Escherichia coli and Klebsiella pneumoniae isolated from poultry, domestic pigs, and environmental samples in the Msimbazi River Basin, Tanzania. Screening 110 isolates for CTX-M, TEM, SHV, qnrA, qnrB, and qnrS genes revealed widespread resistance gene carriage across animal and environmental sources.
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.
