The zebrafish gut microbiome influences benzo[a]pyrene developmental neurotoxicity
Researchers found that the gut microbiome of zebrafish influences developmental neurotoxicity caused by benzo[a]pyrene, a polycyclic aromatic hydrocarbon, showing that microbial community composition modifies how the host responds to early-life toxicant exposure. The study highlighted gut-brain axis interactions as an important dimension of environmental toxicology.
The Role of Danio rerio in Understanding Pollutant-Induced Gut Microbiome Dysbiosis in Aquatic Ecosystems
This review examines how freshwater pollutants—including pesticides, heavy metals, antibiotics, dyes, and microplastics—disrupt gut microbiome composition in zebrafish and other aquatic animals. It highlights the zebrafish model as a key tool for understanding pollutant-driven microbiome dysbiosis and its metabolic consequences.
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. Researchers highlight that changes in gut bacterial communities can serve as sensitive indicators of pollution exposure and may have downstream effects on host fitness. The study calls for improved methodologies to better link contaminant-induced shifts in gut microbiota to measurable health outcomes in aquatic species.
Dysregulation of gut health in zebrafish by differentially charged nanoplastic exposure: an integrated analysis of histopathology, immunology, and microbial informatics
Researchers studied how nanoplastics with different surface charges affect gut health in zebrafish using histopathology, immunology, and microbial analysis. The study found that gut damage and microflora disturbance caused by nanoplastic ingestion significantly depended on the surface functional groups of the particles.
Effects of Aroclor 1254 on Intestinal Immunity, Metabolism, and Microflora in Zebrafish
Zebrafish exposed to the PCB mixture Aroclor 1254 for 21 days at concentrations of 5-15 micrograms per liter showed intestinal inflammation, oxidative stress, gut microbiome disruption, and altered metabolomics profiles in a dose-dependent manner. The results demonstrate that PCBs impair intestinal barrier function and gut health, potentially contributing to systemic toxicity through increased gut permeability.
Chronic Exposure of Adult Zebrafish to Polyethylene and Polyester-based Microplastics: Metabolomic and Gut Microbiome Alterations Reflecting Dysbiosis and Resilience
Researchers exposed adult zebrafish to polyethylene and polyester microplastics at environmentally relevant concentrations and found significant disruptions to metabolic pathways and gut microbiome composition. Polyethylene primarily affected cell membrane compounds and inflammation-related metabolites, while polyester altered lipid metabolism and gut bacterial interactions. The study reveals that chronic microplastic exposure can cause subtle but meaningful shifts in fish metabolism and gut health, even at low concentrations.
Environmental Cadmium Exposure Perturbs Gut Microbial Dysbiosis in Ducks
Environmental cadmium exposure in ducks was found to perturb gut microbial diversity and community composition, with dysbiosis patterns suggesting that heavy metal contamination in agricultural environments can impair gut health in waterfowl.
Exploring the impact of antibiotics, microplastics, nanoparticles, and pesticides on zebrafish gut microbiomes: Insights into composition, interactions, and health implications
This review summarizes how antibiotics, microplastics, nanoparticles, and pesticides each affect the gut microbiome of zebrafish, a widely used model for studying human health impacts. Researchers found that all four types of contaminants can significantly alter gut bacterial composition and disrupt metabolic and immune functions. The study highlights that combined exposures to multiple pollutants may have compounding effects on gut health that are more harmful than any single contaminant alone.
The potential influence of food additives and contaminants on the gut microbiota: A comprehensive review
This comprehensive review examines how food additives and contaminants, including pesticides, heavy metals, microplastics, and antibiotics, affect the gut microbiota. Researchers found that these substances can disrupt the balance of gut microbes, leading to inflammation, gastrointestinal injury, and altered production of beneficial short-chain fatty acids. The study emphasizes the need for further research into the mechanisms by which dietary contaminants affect gut health and overall wellbeing.
In vivo toxicity of industrial biocide containing 2,2-Dibromo-3-nitrilopropionamide in adult and zebrafish larvae
This paper is not about microplastics; it tests the toxicity of an industrial biocide (DBNPA) on zebrafish embryos and adults, finding developmental abnormalities at higher concentrations.
The probiotic SLAB51 as agent to counteract BPA toxicity on zebrafish gut microbiota -liver-brain axis
Researchers tested whether the probiotic supplement SLAB51 could counteract the harmful effects of bisphenol A (BPA), a plastic-derived chemical, in zebrafish and found it significantly restored healthy gut bacteria, reduced liver damage, and protected the brain — suggesting probiotics may help offset harm from plastic-associated chemical exposure.
Acute exposure to microplastics induces metabolic disturbances and gut dysbiosis in adult zebrafish (Danio rerio)
Researchers exposed adult zebrafish to polyethylene and polyester microplastics and used untargeted metabolomics and gut microbiome analysis to assess the effects. The study found that acute microplastic exposure caused significant metabolic disturbances and gut dysbiosis, altering key metabolites involved in lipid and amino acid metabolism.
Plastics in our water: Fish microbiomes at risk?
This review examined how microplastics and leached plasticizers affect the gut microbiomes of freshwater and marine fish, summarizing evidence for dysbiosis and reduced microbial diversity and discussing potential consequences for fish immunity, metabolism, and environmental fitness.
Legacy metal contamination is reflected in the fish gut microbiome in an urbanised estuary
Researchers found that legacy metal contamination in a heavily urbanized estuary in Australia is altering the gut microbiome of local fish, with metal-exposed fish harboring more potentially harmful and inflammation-linked bacteria. This shows that gut microbiome changes in fish can serve as a sensitive biological indicator of environmental pollution, even when the contamination occurred decades ago.
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.
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.
