Adverse effects of polystyrene microplastics in the freshwater commercial fish, grass carp (Ctenopharyngodon idella): Emphasis on physiological response and intestinal microbiome

Researchers exposed grass carp to different sizes and concentrations of polystyrene microplastics for up to 14 days, followed by a depuration period, and assessed physiological and intestinal microbiome effects. The study found that microplastics caused histological damage, oxidative stress, and shifts in gut microbial communities, with smaller particles and higher concentrations producing more severe effects.

Polystyrene microplastics induce endoplasmic reticulum stress, apoptosis and inflammation by disrupting the gut microbiota in carp intestines

Researchers fed carp polystyrene microplastics and found that the particles disrupted their gut bacteria, killing off beneficial species and promoting those linked to diseases. The microplastics triggered a stress response in intestinal cells that led to inflammation, cell death, and tissue damage. Since carp is a widely eaten fish, these gut health effects raise questions about how microplastics in aquatic environments could affect the safety of fish that humans consume.

Polystyrene microplastics induce microbial dysbiosis and dysfunction in surrounding seawater

Researchers used gene sequencing to study how polystyrene microplastics disrupt the microbial community and function in surrounding aquaculture water. The study found that microplastic exposure shifted the balance of beneficial and potentially harmful bacteria, altered nitrogen cycling pathways, and enriched antibiotic resistance genes, suggesting that microplastics in aquaculture settings could compromise water quality and ecosystem health.

Polystyrene nanoplastics sequester the toxicity mitigating potential of probiotics by altering gut microbiota in grass carp (Ctenopharyngodon idella)

Researchers tested whether probiotic pretreatment could protect grass carp from the toxic effects of polystyrene nanoplastics on gut health. While probiotics initially boosted immune responses and reduced intestinal damage, the protective effect was not strong enough to fully counteract nanoplastic toxicity over time. The study suggests that nanoplastics can undermine the gut health benefits of probiotics by disrupting the balance of gut bacteria.

Polystyrene nanoplastics affect digestive function and growth in juvenile groupers

Researchers found that polystyrene nanoplastics accumulated in the liver and intestines of juvenile grouper fish, reducing digestive enzyme activity and impairing growth. The nanoplastics also decreased intestinal microbial diversity while increasing the abundance of harmful bacteria such as Vibrio. The study suggests that nanoplastic exposure can significantly compromise digestive function and overall health in marine fish during early development.
