Microplastic: A potential threat to human and animal health by interfering with the intestinal barrier function and changing the intestinal microenvironment
This review summarizes current research on how microplastics disrupt the gut environment in both animals and humans, focusing on damage to the intestinal barrier.

The ant that may well destroy a whole dam: a systematic review of the health implication of nanoplastics/microplastics through gut microbiota
This systematic review summarizes existing research on how nanoplastics and microplastics disrupt gut bacteria in various organisms. The findings show that plastic particle exposure consistently alters gut microbiome composition, which in turn affects the host's immune function, metabolism, and overall health. These gut bacteria changes may be a key pathway through which microplastics harm human health.
The role of gut microbiota in MP/NP-induced toxicity
This review summarizes how micro- and nanoplastics disrupt gut bacteria and why that matters for overall health. The tiny plastic particles change the composition and function of the gut microbiome, which can trigger inflammation, weaken the intestinal barrier, and potentially contribute to diseases beyond the gut through the immune and nervous systems.
Microplastics and the gut microbiome: Emerging health concerns and strategies
This review covers how microplastic ingestion affects the gut microbiome, describing mechanisms by which microplastics cause intestinal disorders, disrupt endocrine function, and promote pathogenic bacterial growth, while also noting inhalation and dermal absorption as secondary exposure routes.
Gut microbiota as an emerging target for the health implications of microplastics
This review examines how microplastic exposure disrupts the gut microbiome, finding evidence that microplastics damage intestinal barrier proteins, promote inflammation and oxidative stress, and may drive systemic effects including neurotoxicity and reproductive toxicity through gut-mediated pathways.
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.
Are Microplastics Toxic? A Review from Eco-Toxicity to Effects on the Gut Microbiota
This review summarizes existing research on the toxicity of micro- and nanoplastics, from environmental organisms to effects on gut bacteria. Studies show these particles can cause oxidative stress, disrupt energy metabolism, and damage genes in a range of species. With micro- and nanoplastics now found in human blood, lung tissue, and placentas, the authors stress that much more research is needed to understand the full health risks to people.
Impact of micro- and nanoplastics on gastrointestinal diseases: Recent advances
This review summarizes how micro- and nanoplastics can harm the digestive system by causing oxidative stress, inflammation, cell death, and disruption of gut bacteria. These connected pathways can damage the intestinal lining and may contribute to conditions like inflammatory bowel disease and colorectal cancer. The findings highlight the importance of understanding how everyday plastic exposure through food and water could affect gut health over time.
Microbial risks associated with microplastics in the food chain and possible control measures (literature review). Part 1. Dietary intake and influence on the gut microbiota
This review summarizes evidence that microplastics commonly found in food and drinking water can disrupt the human gut microbiome when ingested. Studies show that microplastics alter the composition and function of intestinal bacteria, potentially affecting digestion, immunity, and overall health. Since a healthy gut microbiome is essential for human wellbeing, this pathway of harm deserves attention alongside other known risks of microplastic exposure.
Potential effects of MPs and their co-pollutants on human intestinal tract
This review examines how microplastics and their co-pollutants enter and damage the human intestinal tract, summarizing evidence for microplastic-induced gut barrier disruption, microbiota alteration, and systemic translocation to other organs.
Effect of microplastics and nanoplastics in gastrointestinal tract on gut health: A systematic review.
This systematic review of 30 in vitro studies found that microplastics and nanoplastics cause size- and concentration-dependent damage to human gastrointestinal cells, including increased oxidative stress, mitochondrial dysfunction, inflammation, and apoptosis. Smaller particles consistently showed greater cellular uptake and biological effects, though chronic low-dose exposure generally produced minimal impacts.
Gut microbiota, a key to understanding the knowledge gaps on micro-nanoplastics-related biological effects and biodegradation
This review explores how micro- and nanoplastics affect the community of microorganisms living in the gut, and how those same gut microbes might be able to break down plastic particles. Swallowed microplastics can disrupt the balance of gut bacteria, potentially leading to various diseases. On the other hand, some gut bacteria can actually degrade plastics into smaller, less harmful molecules, opening a possible avenue for biological cleanup.
Gut microbiome remodeling induced by microplastic exposure in humans
This review synthesizes evidence on how microplastic exposure affects the human gut microbiome, drawing on cross-sectional studies of people exposed through plastic food containers and other sources. Evidence indicates that microplastic exposure is associated with shifts in gut bacteria composition, including increases in certain bacterial groups linked to inflammation. The authors explore potential connections between microplastic-induced changes in gut bacteria and the development of various health conditions.
The infiltration of microplastics in human systems: Gastrointestinal accumulation and pathogenic impacts
This review focuses on how microplastics accumulate in the human digestive system and what health problems they might cause. The authors explain that people ingest microplastics through food, water, and air, and these particles may trigger inflammation, disrupt gut bacteria, and potentially contribute to gastrointestinal diseases.

The microplastic-crisis: Role of bacteria in fighting microplastic-effects in the digestive system
This review examines how microplastics affect the human digestive system and explores whether certain bacteria could help counteract the damage. Microplastics disrupt the gut by altering microbial communities, interfering with digestive enzymes, and damaging the protective mucus lining. The authors highlight the potential for probiotic bacteria to bind to microplastics, reduce inflammation, and help repair the gut environment, offering a possible protective strategy against microplastic-related digestive harm.
