ClearUnraveling Microplastic Effects on Gut Microbiota across Various Animals Using Machine Learning
This meta-analysis used machine learning to compare how microplastics affect gut bacteria across different animal species. Mice showed the strongest negative effects, including reduced gut bacterial diversity and imbalanced gut flora — shifts linked to health problems in humans too. The study identified specific bacterial markers, including Lactobacillus, that could help detect microplastic-related gut damage.
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.

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.
Quantitative evaluation of microplastic interference with gut microbiota: Identifying sensitive indicators and key factors
This meta-analysis combined with machine learning found that the Firmicutes-to-Bacteroidetes ratio is the most sensitive biomarker of microplastic-induced gut microbiome disruption, with exposure concentration, particle size, and duration as the key drivers. The resulting predictive model (R=0.91) offers a quantitative tool for assessing gastrointestinal harm from microplastic exposure.
Impacts of microplastics on gut health: Current status and future directions
This systematic review found consistent evidence across mouse, fish, and earthworm models that microplastics disrupt gut microbiota composition, impair intestinal barrier integrity, and trigger gastrointestinal inflammation. The correlation between microplastic exposure and gut health deterioration was statistically significant across all animal models examined.

Microplastics predominantly affect gut microbiota by altering community structure rather than richness and diversity: A meta-analysis of aquatic animals
A phylogenetically controlled meta-analysis of 63 studies across 31 aquatic species found that microplastics significantly alter gut microbiota community structure — with between-group distances 87.75% higher than within-group distances — even at environmentally relevant concentrations. However, microplastics did not significantly affect species richness or Shannon diversity, indicating structural reorganization rather than diversity loss.
The Characteristics of Intestinal Bacterial Community in Three Omnivorous Fishes and Their Interaction with Microbiota from Habitats
This study examined the gut bacterial communities of three omnivorous fish species in artificial fishery habitats, comparing them to bacteria in the surrounding water and sediment. Fish gut microbiomes partially reflected the environmental microbiota, suggesting habitat quality affects fish gut health. This is relevant to microplastics because microplastics alter both aquatic microbial communities and fish gut microbiomes.
