ClearExploring Bacterial Interactions with Microplastics in the Human Gut Microbiome
This review explored how microplastics interact with bacteria in the human gut microbiome, examining evidence that plastic particles can alter microbial community composition, enable colonization by pathogens, and facilitate horizontal gene transfer of antibiotic resistance genes. The gut microbiome appears to be a significant site of microplastic-microorganism interaction.
Association between microplastics exposure and gut microbiota and metabolites in older adults: A cross-sectional study
Researchers analyzed fecal samples from 45 older adults to assess the relationship between microplastic exposure and gut microbiota. They found an average of 70 microplastic particles per gram of feces, primarily PVC, butadiene rubber, and polyethylene, and observed that microplastic exposure was associated with changes in gut microbial diversity and metabolite levels. The study suggests that microplastics may influence gut health in older adults by altering bacterial community composition and metabolic pathways.

Effects of Microplastic on Human Gut Microbiome: Detection of Plastic-Degrading Genes in Human Gut Exposed to Microplastics—Preliminary Study
Researchers analyzed stool samples from Indonesian coastal and highland populations to examine the relationship between microplastic contamination and gut microbiome composition. While microplastics did not significantly alter overall gut microbial diversity, specific plastic types correlated with changes in certain bacterial genera including Roseburia and Prevotella. Notably, the study detected genes encoding plastic-degrading enzymes in the human gut microbiome for the first time, suggesting the gut microbial community may be adapting to microplastic exposure.
Interaction between microplastics and microorganism as well as gut microbiota: A consideration on environmental animal and human health
This review explores how microplastics interact with microorganisms in the environment and within the gut, examining implications for both animal and human health. Researchers found that microplastics can alter gut microbiota composition, promote the spread of antibiotic-resistant bacteria, and amplify the toxicity of other environmental pollutants. The study suggests that the interaction between microplastics and gut microorganisms is an important emerging area for understanding health risks.
How do microplastics affect the composition and function of gut microbiota?
Researchers reviewed how microplastics may disrupt gut microbiota composition and metabolic function, noting that while dysbiosis is a likely outcome of exposure, the full scope of these effects in humans remains understudied.
How do microplastics affect the composition and function of gut microbiota?
Researchers reviewed how microplastics may disrupt gut microbiota composition and metabolic function, noting that while dysbiosis is a likely outcome of exposure, the full extent of these effects in humans remains poorly characterized and understudied.
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.
Microplastics and human health: unveiling the gut microbiome disruption and chronic disease risks
This review summarizes evidence that microplastics disrupt the gut microbiome, the community of bacteria in our digestive system that plays a key role in immunity, metabolism, and overall health. By altering gut bacteria balance and triggering inflammation, microplastic exposure may contribute to chronic conditions including inflammatory bowel disease, metabolic disorders, and potentially even neurological problems through the gut-brain connection.
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.
Impact of microplastics on the human gut microbiome: a systematic review of microbial composition, diversity, and metabolic disruptions
This systematic review of 12 studies found that microplastics including polyethylene, polystyrene, and PVC induce gut dysbiosis in humans, reducing beneficial bacteria and enriching pathogens. Microplastic exposure also impairs short-chain fatty acid production and modulates immune pathways, contributing to intestinal disease, metabolic syndrome, and chronic inflammation.
Impact of microplastics on the intestinal microbiota: A systematic review of preclinical evidence
Across 28 preclinical studies, microplastics triggered intestinal dysbiosis characterized by increased Firmicutes and Proteobacteria and decreased Bacteroidetes, while increasing gut permeability and elevating pro-inflammatory cytokines including IL-1β, TNF-α, and IL-6.
Microplastic-associated gut microbial profile and antibiotic resistance in preschool children: a multicentre cross-sectional study in China
In a multicentre study of 335 preschool children across three Chinese cities, researchers detected eight types of microplastics in fecal samples at a median concentration of 212.1 micrograms per gram. The study found that microplastic exposure was associated with changes in gut microbiota composition and function, including metabolic pathways related to macronutrients and vitamins, as well as a relationship with antibiotic resistance gene abundance.
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.
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.
Polystyrene microplastic exposure induces selective accumulation of antibiotic resistance genes in gut microbiota and its potential health risks
Researchers used advanced genomic techniques to examine how polystyrene microplastic exposure affects antibiotic resistance genes in the gut bacteria of rats. They found that microplastic exposure selectively increased certain types of antibiotic resistance genes and promoted their ability to transfer between bacterial species. The study suggests that microplastic ingestion could contribute to the spread of antibiotic resistance within the gut, posing potential health risks.

Microplastics as vectors for antibiotic resistance genes and their implications for gut health
This review explains how microplastics in the environment serve as platforms for antibiotic-resistant bacteria to grow, creating what scientists call a 'plastisphere.' When people ingest these contaminated microplastics through food and water, the antibiotic-resistant genes may transfer to gut bacteria, potentially making infections harder to treat with standard antibiotics.
Perturbation of gut microbiota plays an important role in micro/nanoplastics-induced gut barrier dysfunction
Researchers investigated how micro- and nanoplastics disrupt gut barrier function in mice, finding that different surface chemistries caused varying levels of damage. The study suggests that these plastic particles harm the gut by altering the gut microbiome, which then leads to inflammation and weakening of the intestinal barrier that normally keeps harmful substances out of the body.
