Researchers isolated six bacterial genera from the gut of common carp (Cyprinus carpio) and identified two novel Hafnia strains with both probiotic potential and microplastic-degrading properties, suggesting a dual role for gut bacteria in fish health and environmental bioremediation.
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.
DataSheet1_Interactive Effects of Microplastics and Tetracycline on Bioaccumulation and Biochemical Status in Jian Carp (Cyprinus carpio var. Jian).docx
This study investigated how microplastics and the antibiotic tetracycline interact when both are present in water and ingested by carp. Microplastics acted as carriers, helping tetracycline accumulate in fish tissues at higher levels than tetracycline alone. The findings raise concerns about how microplastics can amplify antibiotic contamination in fish consumed by people.
Antibiotic Resistance Gene Enrichment on Plastic Wastes in Aquatic Ecosystems and Fishery Products
This review examined how plastic waste in aquatic environments enriches antibiotic resistance genes (ARGs) through plastisphere biofilms, with implications for fishery product safety. Microplastic-associated biofilms concentrate ARG-carrying bacteria, increasing the risk of antibiotic resistance transmission through fish and other seafood consumed by humans.
Polyvinyl chloride microplastics in the aquatic environment enrich potential pathogenic bacteria and spread antibiotic resistance genes in the fish gut
When carp were exposed to PVC microplastics along with common antibiotics, the combination promoted the growth of potentially harmful bacteria and increased the number of antibiotic resistance genes in the fish gut. This is concerning for human health because antibiotic-resistant bacteria can transfer from aquatic environments and food fish to people, making infections harder to treat.
Antibiotic resistant bacteria in diverse ecological water samples are a threat to Human Food security
Researchers isolated antibiotic-resistant bacteria from three aquatic sources -- the River Ravi, a fish farm, and underground drinking water -- identifying 33 bacterial strains across genera including Enterobacteriaceae, Pseudomonas, and Staphylococcus, and finding resistance to 8 of 10 antibiotic classes with multiple antibiotic resistance indices ranging from 0.43 to 0.88.
Dynamics of Gut Microbiome and Transcriptome in Korea Native Ricefish (Oryzias latipes) during Chronic Antibiotics Exposure
Researchers found that chronic low-dose exposure to erythromycin and ampicillin antibiotics disrupted the gut microbiome composition and altered immune and stress gene expression in Japanese rice fish (Oryzias latipes), suggesting that antibiotic residues in aquatic environments can cause lasting physiological effects in fish.
A Review on the Main Antibiotic Drugs Used in Fish Farming: Ecotoxicity, Characterization and Remediation
This review examines antibiotics used in fish farming and their ecotoxicological effects on aquatic ecosystems, noting that pharmaceutical residues accumulate in water and sediments and promote antibiotic-resistant bacteria. Understanding drug fate and effects in aquaculture environments is important for protecting both ecosystem health and the safety of farmed seafood.
Microplastic contamination in fish: A systematic global review of trends, health risks, and implications for consumer safety
This systematic global review summarizes research on microplastic contamination in fish, covering bioaccumulation, food chain transfer, and the role of microplastics as carriers of antibiotic-resistant bacteria and toxic chemicals. The review compares contamination levels in farmed versus wild-caught fish and finds risks vary significantly depending on the source. The findings are directly relevant to consumer safety, as people regularly consume microplastics through contaminated seafood.
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.
Ingested Microplastics Can Act as Microbial Vectors of Ichthyofauna
Nylon strips ingested and excreted by wild fish were found to harbor adherent microbiota including potential pathogens, demonstrating that microplastics can vector microorganisms through fish gut passage and into aquatic environments.
Aquaculture Water Quality Improvement by Mixed Bacillus and Its Effects on Microbial Community Structure
This study tested two combinations of beneficial Bacillus bacteria in crucian carp aquaculture tanks, finding they improved water quality by reducing nitrogen and phosphorus compounds and shifted microbial community structure toward more beneficial species. Probiotic bacterial treatments offer a sustainable alternative to antibiotics for maintaining aquaculture water quality.
Biofilm formation on microplastics and interactions with antibiotics, antibiotic resistance genes and pathogens in aquatic environment
This review explains how microplastics in waterways develop bacterial biofilms on their surfaces that can harbor antibiotic-resistant bacteria and help spread antibiotic resistance genes to new environments. This is concerning for human health because these resistant microbes could eventually reach people through drinking water or seafood consumption.
A review focusing on mechanisms and ecological risks of enrichment and propagation of antibiotic resistance genes and mobile genetic elements by microplastic biofilms
This review examines how microplastics in water serve as surfaces for bacterial biofilms that harbor antibiotic resistance genes. The biofilms that form on microplastic surfaces can spread resistance genes to other bacteria and potentially to organisms that ingest them, including fish and ultimately humans. The authors highlight that microplastic-associated antibiotic resistance is an underappreciated public health risk that needs more research.
A Review of Antibiotics, Antibiotic Resistant Bacteria, and Resistance Genes in Aquaculture: Occurrence, Contamination, and Transmission
This review examines how overuse of antibiotics in fish farming leads to antibiotic-resistant bacteria and resistance genes that spread through water, sediment, and the organisms themselves. This is relevant to microplastic pollution because microplastics in aquaculture environments can carry antibiotic-resistant bacteria, potentially transferring these dangerous genes to humans through the food chain.
Effectiveness assessment of using water environmental microHI to predict the health status of wild fish
Researchers tested whether measuring the health of microbial communities in river water could predict the health status of wild fish living there. The study found that the environmental microbiota health index was effective for bottom-dwelling fish but less reliable for fish living in the open water, suggesting this non-invasive monitoring approach works best for certain types of aquatic species.
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.
Effect of chlorpyrifos on freshwater microbial community and metabolic capacity of zebrafish
Researchers exposed zebrafish and their surrounding water to chlorpyrifos, a widely used pesticide, and found it disrupted the diversity of aquatic microbes, increased dangerous antibiotic-resistant bacteria, and altered the gut metabolism of fish — raising concerns about the ecological and food-safety risks of pesticide runoff into waterways.

Researchers characterized the skin and intestinal microbiomes of migratory Arctic lake whitefish and cisco, finding that microbial communities varied between species and body sites, with implications for understanding fish health in changing Arctic environments.
Microplastic Distribution Patterns in Fish and Implications for Safe Consumption
Researchers examined over 1,000 fish from 37 species and found microplastics in the gills and guts of about 36-40% of fish, but none in muscle tissue. Fish from shallower waters and smaller fish had more microplastics. The study recommends that people eat only the muscle portion of fish and choose larger fish from deeper waters to reduce their microplastic intake, estimating that global per capita exposure from fish is about 56,000 particles per year.
Microplastic and associated emerging contaminants in marine fish from the South China Sea: Exposure and human risks
Researchers found microplastics in all 14 marine fish species tested from the South China Sea, along with antibiotics and PFAS chemicals. Fish with more microplastics in their guts also had higher levels of certain chemical contaminants in their flesh, suggesting microplastics may act as carriers that increase the amount of harmful chemicals in seafood consumed by humans.
