ClearIngestion and digestion by the freshwater snail Pomacea canaliculata drive microplastic surface transformations and virus-mediated plastisphere functional shifts
Researchers exposed freshwater apple snails to polystyrene and expanded polystyrene microplastics, finding that snail digestion deformed EPS particles and induced surface oxidation of both plastic types, while also altering plastisphere virus and bacterial communities and affecting antibiotic resistance patterns.
Adaptive gut microbiota dysbiosis coupled with altered fatty acid metabolism in apple snails (Pomacea canaliculata): A potential strategy against polystyrene microplastic stress
Researchers exposed apple snails to polystyrene microplastics for 21 days and found that higher concentrations reduced food intake and weight gain while causing oxidative stress in intestinal tissues. The microplastics also significantly altered the snails' gut microbiome composition and disrupted fatty acid metabolism. The study suggests that freshwater snails may adapt to microplastic stress through changes in their gut bacteria and metabolic pathways, though at a cost to their overall health.
The plastisphere ecology: Assessing the impact of different pollution sources on microbial community composition, function and assembly in aquatic ecosystems
Researchers studied the microbial communities living on microplastic surfaces (called the plastisphere) across four different aquatic sites and found that plastics host a distinctly different mix of microbes than the surrounding water, shaped by local pollution sources. These plastic-surface microbes also carry more antibiotic resistance genes and show greater potential for breaking down plastics, making the plastisphere both a health concern and a potential bioremediation resource.
Effects of microplastics on Daphnia-associated microbiomes in situ and in vitro
This study investigated how microplastic exposure alters the microbiome associated with Daphnia in freshwater, finding shifts in bacterial community composition that may affect host health and ecological function. The results suggest that microplastics can indirectly harm zooplankton by disrupting their microbial symbionts.
Impact of microplastics exposure on the reconfiguration of viral community structure and disruption of ecological functions in the digestive gland of Mytilus coruscus
Researchers studied how polyethylene microplastic ingestion affects the viral community in the digestive glands of thick-shelled mussels through a field exposure experiment. They found that microplastic ingestion significantly reduced virome diversity and altered viral community composition, while microplastic biofilms carried abundant antibiotic resistance genes and virulence factors. The findings suggest that microplastics may serve as vectors for spreading resistance genes and destabilizing microbial networks in marine organisms.
The ecology of the plastisphere: Microbial composition, function, assembly, and network in the freshwater and seawater ecosystems
Researchers studied the communities of bacteria and fungi that colonize microplastic surfaces in freshwater and seawater, forming what scientists call the plastisphere. These microplastic-associated communities were distinctly different from those in surrounding water, and included a higher proportion of disease-causing organisms and species involved in pollutant degradation. The findings suggest that microplastics create new habitats that can harbor pathogens and alter natural microbial ecosystems in ways that may affect water quality and human health.
Microplastic Exposure Across Trophic Levels: Effects on the Host Microbiota of Freshwater Organisms
Researchers investigated how microplastic exposure affects the gut bacteria communities of freshwater organisms including fish, invertebrates, and crustaceans. Microplastics—particularly when combined with pesticides—altered gut microbiota composition, which could impair digestion, immunity, and overall health of freshwater species.
Promotion of antibiotic-resistant genes dissemination by the micro/nanoplastics in the gut of snail Achatina fulica
Researchers studied how micro- and nanoplastics affect the spread of antibiotic resistance genes in the gut of edible snails. They found that smaller plastic particles at higher concentrations significantly promoted the transfer of resistance genes between bacteria through conjugation. The study suggests that plastic contamination in food animals could accelerate the spread of antibiotic resistance, which is a growing public health concern.
Microplastic exposure across trophic levels: effects on the host–microbiota of freshwater organisms
Researchers examined how microplastic exposure across trophic levels affects the gut microbiota of freshwater organisms, finding that microplastics alter microbial community composition and that effects can transfer through food web interactions.
Microbial communities on microplastics from seawater and mussels: Insights from the northern Adriatic Sea
Researchers studied the microbial communities that colonize microplastics in seawater and mussels from the northern Adriatic Sea, including the first-ever genetic sequencing of a microplastic particle recovered from inside a mussel. They found that the microbes on particles from both environments were similar, suggesting a shared colonization pattern. The presence of potentially harmful bacteria like Campylobacter on some particles raises questions about microplastics serving as vehicles for pathogen transfer in the marine food chain.
Microbiomes on microplastics versus natural microcarriers: Stability and transformation during aquatic travel from aquaculture ponds to adjacent stream
Researchers compared microbial communities that form on microplastics versus natural materials as they travel from aquaculture ponds to adjacent streams. They found that different plastic types harbored distinct microbial communities, and that these plastisphere communities were less stable than those on natural substrates during transit between water bodies. The study suggests that microplastics may spread different assemblages of microorganisms as they move through connected aquatic environments.
Microplastics: New substrates for heterotrophic activity contribute to altering organic matter cycles in aquatic ecosystems
This study demonstrated that heterotrophic bacteria colonizing microplastic surfaces in aquatic ecosystems have distinct metabolic capabilities and can process organic matter at rates different from planktonic bacteria. The findings suggest that the plastisphere — the microbial community on plastic surfaces — may alter organic matter cycling in aquatic environments as microplastic abundance grows.

This review examines the communities of microbes that colonize plastic debris in freshwater environments, known as the "plastisphere." These microbial communities include potentially dangerous bacteria and organisms that can carry antibiotic resistance genes, meaning plastic pollution may serve as a vehicle for spreading pathogens and drug-resistant infections through water systems that people rely on.
Microplastic exposure reshapes the virome and virus–bacteria networks with implications for immune regulation in Mytilus coruscus
Researchers exposed mussels to microplastics for seven days and analyzed how the pollution affected viral communities in their tissues. They found that microplastic exposure suppressed DNA virus diversity while activating RNA viral metabolism, and restructured interactions between bacteria-infecting viruses and opportunistic pathogens. The study suggests that microplastics may influence immune function in shellfish by reshaping the viral community and virus-mediated immune interactions.
