ClearPolystyrene microplastics disrupted physical barriers, microbiota composition and immune responses in the cecum of developmental Japanese quails
Researchers fed Japanese quails environmentally relevant concentrations of polystyrene microplastics for five weeks and examined their gut health. They found that microplastics damaged the physical barriers of the cecum, disrupted the gut microbial community, and impaired immune responses. The study suggests that even low-level microplastic contamination in the environment could compromise gut health and immune function in birds.

Researchers fed quails different levels of polyethylene microplastics and found that exposure harmed their growth, reproduction, and gut health. The microplastics reduced antioxidant defenses and disrupted the balance of beneficial bacteria in the birds' intestines. Since poultry is a major food source for people, microplastic contamination in farm animals raises concerns about indirect human exposure through the food chain.

Researchers exposed Japanese quail to microplastics and found that the effects on fatty acid composition varied depending on both the sex of the bird and the size of the plastic particles. The study suggests that microplastic ingestion may disrupt lipid metabolism in birds, with potential implications for their health and reproductive fitness.
Gut dysbiosis: Nutritional causes and risk prevention in poultry, with reference to other animals
This review examines the causes and consequences of gut dysbiosis in poultry and other animals, identifying microplastics as one of several environmental pollutants that can disrupt gastrointestinal microbial communities. Researchers describe how reduced microbial diversity leads to inflammation, compromised gut barriers, and disorders affecting multiple organ systems. The study highlights that microplastics, along with heavy metals, pesticides, and other contaminants, contribute to the growing challenge of maintaining healthy gut microbiomes in animal populations.
Impact of microplastics on human gut microbiota: first evidences from in vitro gut models
Researchers investigated the impact of microplastics on human gut microbiota using in vitro gut models, providing early experimental evidence of how microplastic exposure may disrupt intestinal microbial communities. The study offers foundational data on microplastic-microbiome interactions that are difficult to study directly in humans.
Review: interactions between microplastics and the gastrointestinal microbiome
This review summarizes existing research on how microplastics interact with the gut microbiome in humans, mice, chickens, and aquatic animals. Evidence suggests that gut bacteria can break microplastics into smaller pieces, which may make them more likely to cross the intestinal wall and enter the body. The disruption of the gut microbiome by microplastics is particularly concerning because balanced gut bacteria are essential for immune function, digestion, and overall health.
Microplastics as an aquatic pollutant affect gut microbiota within aquatic animals
This review examined how microplastics affect the gut microbiota of aquatic animals, analyzing the roles of plastic-associated chemicals and biofilms in disrupting microbial communities from ingestion through physiological impacts.

Researchers exposed marine mussels (Mytilus edulis) to microplastics and analyzed changes to their gut microbiota, finding significant shifts in microbial community composition that could affect digestion, immunity, and overall health.
Microplastics-gut microbiota interactions in an in vitro model of the toddler colon
Researchers used an in vitro model of the toddler colon to investigate how microplastics interact with the gut microbiota in young children. The study examined changes in microbial community composition and metabolic activity following microplastic exposure, providing early evidence of potential disruption to the developing gut ecosystem.
The impact of microplastics on the mice gut microbiome: a meta-analysis
This meta-analysis pools data from multiple mouse studies to assess how ingested microplastics affect gut bacteria. It found that microplastic exposure can alter the balance of the gut microbiome, which is important because gut health is closely tied to immune function, digestion, and overall well-being.
Ecotoxicological impacts of microplastics to gut microbiota: Response mechanism, challenges and environmental sustainability-A review
This review summarizes how microplastics affect gut bacteria in fish, mice, and earthworms after being swallowed. Microplastics can change the balance of gut microbes and reduce their helpful functions, leading to digestive problems, slower growth, and weakened immunity. Since humans are exposed to microplastics through food and water, these findings raise concerns that our own gut health could be similarly affected.
Microplastics and the gut microbiome: How chronically exposed species may suffer from gut dysbiosis
This review explores how chronic microplastic exposure may disrupt the natural balance of gut bacteria in wildlife, a condition known as dysbiosis. Researchers suggest that ingesting microplastics can cause mechanical damage to the gastrointestinal tract, introduce foreign bacteria, and deliver chemical additives that disturb gut microbial communities. The study highlights that microplastic-induced gut dysbiosis could weaken immune systems, promote infections, and contribute to chronic health issues in exposed species.
