ClearPolystyrene microplastics alter the intestinal microbiota function and the hepatic metabolism status in marine medaka (Oryzias melastigma)
Researchers fed marine medaka fish polystyrene microplastics of two sizes for 28 days and examined effects on gut microbiota and liver metabolism. They found that microplastic exposure significantly altered the functional composition of gut bacteria and disrupted hepatic metabolic pathways, even without causing visible tissue damage. The study suggests that microplastics can affect fish health through subtle microbiome and metabolic changes that precede obvious physical harm.
Effects of polystyrene microplastics on the composition of the microbiome and metabolism in larval zebrafish
Researchers exposed larval zebrafish to two sizes of polystyrene microplastics and found significant changes in gut microbiome composition and metabolic activity. The microplastics altered the abundance and diversity of gut bacteria and disrupted metabolic pathways important for development. The study suggests that early-life exposure to microplastics could have meaningful biological consequences by reshaping the gut environment of developing organisms.

Researchers exposed zebrafish to polystyrene microplastics for 21 days and found significant intestinal inflammation, oxidative stress, and disruption of both the gut microbiome and metabolic processes. The microplastics altered the balance of beneficial and harmful gut bacteria and changed the levels of key metabolites involved in energy and amino acid metabolism. The study provides detailed evidence that microplastic ingestion can cause widespread disruption to gut health in aquatic organisms.
Polystyrene microplastics induce microbiota dysbiosis and inflammation in the gut of adult zebrafish
Researchers exposed adult zebrafish to polystyrene microplastics of two different sizes for 14 days and found significant disruptions to the gut microbiome, including shifts in key bacterial populations. Smaller microplastic particles also triggered inflammatory responses in the gut, with elevated levels of inflammatory markers at both the gene and protein level. The study suggests that microplastic ingestion can disturb gut bacteria balance and cause intestinal inflammation in aquatic organisms.
Size-dependent adverse effects of microplastics on intestinal microbiota and metabolic homeostasis in the marine medaka (Oryzias melastigma)
Researchers exposed marine medaka fish to different sizes of polystyrene microplastics for 60 days and found that particle size was a key factor in determining health effects. Larger particles (200 micrometers) caused weight gain and fat accumulation, while smaller particles (2 and 10 micrometers) led to liver inflammation and damage. The study also revealed that microplastics disrupted the balance of gut bacteria, particularly with larger particle exposure.
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.
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.
