This is relevant to microplastics because microplastics alter both aquatic microbial communities and fish gut microbiomes.
Characteristics of microplastic pollution in golden pompano (Trachinotus ovatus) aquaculture areas and the relationship between colonized-microbiota on microplastics and intestinal microflora
Researchers found that microplastics in golden pompano aquaculture areas colonize with distinct microbial communities that overlap with the fish's gut microbiota, increasing Proteobacteria and decreasing Firmicutes in the intestinal flora of fish living in more contaminated estuarine settings.
Impact of polypropylene microplastics and chemical pollutants on European sea bass (Dicentrarchus labrax) gut microbiota and health
Researchers investigated how polypropylene microplastics, alone and combined with chemical pollutants, affect the gut health and microbiome of European sea bass. They found that microplastic ingestion altered the gut microbial community composition and that combined exposure with pollutants amplified the harmful effects. The study suggests that microplastics may serve as carriers for toxic chemicals, compounding their impact on fish health and potentially affecting seafood safety.
Microplastic Exposure Across Trophic Levels: Effects on the Host Microbiota of Freshwater Organisms
Researchers investigated how microplastic exposure affects the gut bacteria communities of freshwater organisms including fish, invertebrates, and crustaceans. Microplastics—particularly when combined with pesticides—altered gut microbiota composition, which could impair digestion, immunity, and overall health of freshwater species.
Microplastics Change the Food Utilization of Filter-Feeding Fish via Gut Microbiota
Researchers found that microplastic exposure changed the food utilization patterns of filter-feeding silver carp by altering their gut microbiota. After exposure, the fish shifted from primarily consuming phytoplankton to greater utilization of zooplankton, driven by microplastic-induced changes in gut bacterial communities that affected digestive enzyme gene expression, suggesting microplastics can disrupt aquatic food web dynamics.
Multi-omics association pattern between gut microbiota and host metabolism of a filter-feeding fish in situ exposed to microplastics
Scientists exposed filter-feeding fish to environmentally realistic levels of microplastics and found that the particles reshaped gut bacteria communities, which in turn altered the fish's liver metabolism through changes in amino acid processing. This gut-microbiome-to-organ connection matters because it shows microplastics may affect human health not just through direct toxicity but by disrupting the beneficial bacteria in our digestive systems.
Polystyrene microplastics induce gut microbiome and metabolome changes in Javanese medaka fish (Oryzias javanicus Bleeker, 1854)
Researchers found that polystyrene microplastic exposure altered gut microbiome composition and metabolic profiles in Javanese medaka fish, with effects on amino acid and lipid metabolism pathways suggesting microplastics can disrupt gut health in aquatic organisms.
Microplastic exposure across trophic levels: effects on the host–microbiota of freshwater organisms
Researchers examined how microplastic exposure across trophic levels affects the gut microbiota of freshwater organisms, finding that microplastics alter microbial community composition and that effects can transfer through food web interactions.
Effects of microplastics on trophic parameters, abundance and metabolic activities of seawater and fish gut bacteria in mesocosm conditions
Mesocosm experiments showed that microplastics altered bacterial community structure and metabolic activity in both seawater and fish guts, suggesting that plastic pollution can disrupt microbial ecosystems in the marine environment. The findings raise concerns about how microplastic-driven microbiome changes could affect fish health and broader ecosystem functioning.
Effects of polystyrene nanoplastics on oxidative stress, histopathology and intestinal microbiota in largemouth bass (Micropterus salmoides)
Researchers exposed largemouth bass — a commercially important freshwater fish — to polystyrene nanoplastics (tiny plastic particles 100 nanometers in size) for up to 19 days, finding tissue damage in the gills, liver, and intestines along with elevated markers of cellular stress. While growth was not significantly affected, the fish adjusted their gut microbiome in response, suggesting nanoplastics trigger adaptive but potentially harmful physiological changes.
Microplastics Changethe Food Utilization of Filter-FeedingFish via Gut Microbiota
Silver carp exposed to microplastics showed a shift in food utilization — increasing zooplankton assimilation from 28% to 40% while decreasing phytoplankton utilization — mediated by changes in gut microbiota, suggesting MPs alter how filter-feeding fish process their food.
Microplastics as an aquatic pollutant affect gut microbiota within aquatic animals
This review examined how microplastics affect the gut microbiota of aquatic animals, analyzing the roles of plastic-associated chemicals and biofilms in disrupting microbial communities from ingestion through physiological impacts.
A fishy gut feeling – current knowledge on gut microbiota in teleosts
This review summarizes what scientists know about the community of bacteria living in fish guts and how diet, environmental conditions, and pollutants shape that community. Microplastics and other pollutants can disrupt the gut microbiome in fish, harming their immune function and overall health. Since fish are a major food source for humans, understanding these effects matters for food safety.
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.

Novel Autochthonous Strains from Cyprinus carpio as Candidates for Probiotic Use and Microplastic-Degrading Properties
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.
Dietary rayon microfibers differentially reshape rearing water and host associated microbiomes of farmed European sea bass (Dicentrarchus labrax)
Researchers found that feeding European sea bass rayon microfibers — a type of textile microplastic — disrupted the bacteria living in the fish's gut and in the surrounding water in a dose-dependent way. This shows that microplastic ingestion can alter the microbial communities of farmed fish, with potential implications for aquaculture health and food safety.
The effect of planktivorous fish (juvenile Perca fluviatilis) on the taxonomic diversity of microplastic particles-colonized bacterial community
Researchers tested whether the presence of perch (a common freshwater fish) affects the bacterial communities colonizing microplastic particles in water. Fish exudates — waste products released into the water — significantly increased the abundance and diversity of bacteria growing on both polyethylene and polystyrene surfaces, which could eventually accelerate microbial degradation of the plastics. This has implications for understanding the long-term fate of microplastics in natural lake and river environments where fish and plastic debris coexist.
Gut microbiota of aquatic organisms: A key endpoint for ecotoxicological studies
This review examines how environmental contaminants including microplastics, pesticides, heavy metals, and pharmaceuticals affect the gut microbiota of aquatic organisms.
