Effect of emerging pollutants on the gut microbiota of freshwater animals: Focusing on microplastics and pesticides
AI summary Read the abstract
This review examines how microplastics and pesticides, two pollutants commonly found together in freshwater, each disrupt the gut bacteria of fish and other aquatic animals, and their combined presence can make the effects worse. Changes in gut bacteria caused by these pollutants can impair metabolism, immunity, and overall health of aquatic organisms, with potential consequences for the food chain.
In recent years, emerging environmental pollutants have increasingly endangered the health of freshwater organisms. The gut microbiota exhibits sensitivity to medications, dietary factors and environmental pollutants, rendering it a novel target for toxicological studies. The gut microbiota can be a potential exposure route affecting the host's health. Herein, we review the current knowledge on two different but concurrent pollutants, microplastics and pesticides, regarding their impact on the gut microbiota, which includes alterations in microbial composition, gene expression, function, and health effects in the hosts. Moreover, synergetic interactions between microplastics and pesticides can exacerbate dysbiosis and health risks. We discuss health-related implications of gut microbial changes based on the consequences in metabolism, immunity, and physiology function. Further research is needed to discover the mechanisms underlying these effects and develop strategies for mitigating their harmful impacts on freshwater animals.

Gut microbiota of aquatic organisms: A key endpoint for ecotoxicological studies
AI summary Read the abstract
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.
Multi stress system: Microplastics in freshwater and their effects on host microbiota
AI summary Read the abstract
This study examined how combined exposure to microplastics and organic chemical pollutants affects freshwater organisms through a multi-stress approach, focusing on gut microbiome changes as an indicator. Microplastic exposure in combination with other pollutants altered microbiome composition more than either stressor alone, with potential consequences for host fitness and disease resistance.
