Quercetin Prevents Bisphenol S Induced Behavioral Changes and Oxidative Stress iZebrafish by Modulating Brain Antioxidant Defense Mechanism
Researchers found that quercetin supplementation in zebrafish exposed to bisphenol S reduced oxidative stress markers and normalized abnormal behavioral responses in the brain, suggesting the natural antioxidant may counteract some neurotoxic effects of this common plastic additive.
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.
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.
Fermented Wheat Bran Polysaccharides Improved Intestinal Health of Zebrafish in Terms of Intestinal Motility and Barrier Function
Researchers found that fermented wheat bran polysaccharides improved intestinal health in zebrafish by enhancing intestinal motility and barrier function, suggesting their potential as functional food additives for gut health.
Ameliorating potential of Cassia absus seed-powder against cadmium-induced alterations in Zebrafish and identification of flavonoids in different extracts of seed
Researchers investigated the protective effects of Cassia absus seed powder against cadmium-induced toxicity in zebrafish, finding it reduced oxidative stress and histological damage, while identifying flavonoid compounds in the seed extracts as likely active components.
Antioxidative Defense and Gut Microbial Changes under Pollution Stress in Carassius gibelio from Bucharest Lakes
Researchers compared antioxidative responses and gut microbiome changes in Prussian carp collected from polluted and less-polluted lakes in Bucharest, finding that fish from more contaminated sites showed elevated oxidative stress markers and altered microbial communities consistent with exposure to heavy metals and other aquatic pollutants.
Small fish, big discoveries: zebrafish shed light on microbial biomarkers for neuro-immune-cardiovascular health
This review highlighted how zebrafish serve as a powerful model for studying gut microbiome links to cardiovascular, neurological, and immune health, identifying microbial biomarkers that could inform future research on environmental stressor impacts including microplastic exposure.
Microplastics induce intestinal inflammation, oxidative stress, and disorders of metabolome and microbiome in zebrafish
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.
Curcumin Attenuates Zearalenone-Induced Reproductive Damage in Mice by Modulating the Gut Microbe–Testis Axis
Researchers investigated whether curcumin, a compound from turmeric, could protect mice from reproductive damage caused by the food-contaminating toxin zearalenone. They found that curcumin improved sperm quality and testicular health by restoring beneficial gut bacteria and reducing inflammation through the gut-testis connection. The study suggests that gut microbiome modulation could be a pathway for protecting reproductive health from environmental toxins.
Sodium Humate Alleviates Enterotoxigenic Escherichia coli-Induced Intestinal Dysfunction via Alteration of Intestinal Microbiota and Metabolites in Mice
Researchers found that sodium humate supplementation alleviated intestinal damage caused by enterotoxigenic Escherichia coli infection in mice by improving gut microbiota composition, modulating metabolites, and reducing intestinal inflammation and barrier dysfunction.
The Effects of Probiotics on the Recovery of Growth, Digestive, Antioxidant, Immune Functions, and Gut Microbiota of Chinese Hooksnout Carp (Opsariichthys bidens) Under Microplastic Stress
Researchers exposed juvenile Chinese hooksnout carp to polystyrene microplastics for seven days, then administered Bacillus coagulans probiotics at three doses for 56 days and found that medium and high probiotic doses significantly improved growth, digestive enzyme activity, antioxidant function, and gut microbiota recovery.
Modern research on the study of the intestinal microbiome in fish (review)
This review examines recent research on the intestinal microbiome of fish, synthesizing findings on microbiome composition across more than 100 teleost species and exploring the microbiome as a potential biomarker for fish health and aquaculture optimization.
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.
Antioxidant and Microbiota Characteristics Across Different Mucosal Sites of Rice Flower Carp (Procypris merus)
Researchers characterized antioxidant activity and microbiota composition across gill, skin, and intestinal mucosal sites in rice flower carp (Procypris merus), finding distinct profiles at each site with gill tissue showing the highest catalase activity and oxidative stress markers. The study provides baseline data on mucosal immune and microbial differences across body sites in this underexplored fish species.

Role of Gut Microbiota in Modulating Oxidative Stress Induced by Environmental Factors
This review examines how environmental pollutants, including microplastics, toxic metals, and antibiotics, disrupt the balance of gut bacteria and trigger oxidative stress throughout the body.
