ClearPathogens transported by plastic debris: does this vector pose a risk to aquatic organisms?
This review examined whether microplastics act as vectors for pathogenic bacteria, viruses, and other pathogens in marine and freshwater ecosystems. Evidence indicates that diverse microorganisms including pathogens adhere to microplastic surfaces, and modeling suggested potential for long-range pathogen transport, though the scale of ecological and public health risk remains uncertain.
Microplastics as Vectors of Chemicals and Microorganisms in the Environment
This review examines microplastics as vectors for chemicals and microorganisms in the environment, discussing the 'plastisphere' concept, hydrophobic surface interactions that facilitate pollutant adsorption, biofilm formation, and the mechanisms by which microplastics transport contaminants and pathogens through aquatic systems.
Plastics as vectors for pathogens and antibiotic resistance genes in aquatic systems.
This review examined how plastics in aquatic systems act as vectors for pathogens and antibiotic resistance genes, summarizing attachment mechanisms, transport dynamics, and the implications for water quality and public health.
The hidden risk of microplastic-associated pathogens in aquatic environments
This review examines the overlooked risk that microplastics in water can serve as vehicles for disease-causing bacteria and other pathogens. Microplastics provide a surface where harmful microorganisms can grow, survive longer, and travel farther than they would on their own. This means microplastic pollution in lakes, rivers, and oceans could increase the risk of waterborne infections in people who swim in, drink from, or eat seafood from contaminated water.
Biofilm-Developed Microplastics As Vectors of Pollutants in Aquatic Environments
This review examines how biofilms that form on microplastics in aquatic environments change their ability to absorb and transport pollutants. Researchers found that biofilm-coated microplastics can absorb more contaminants than clean microplastics and serve as vectors that transfer both pollutants and potentially harmful microorganisms through aquatic ecosystems.
Distribution, biological effects and biofilms of microplastics in freshwater systems - A review
This review examines microplastic distribution, biological effects, and biofilm formation in freshwater systems, highlighting knowledge gaps compared to marine studies and the ecological risks posed by microplastics as vectors for pathogens and pollutants.
Micro(nano)plastics: Unignorable vectors for organisms
This review examines the role of micro- and nanoplastics as vectors for contaminants — including heavy metals, organic pollutants, and pathogens — in aquatic and terrestrial environments. It synthesizes evidence on how plastic particles can adsorb, transport, and release harmful substances, amplifying their ecological and health risks beyond the physical effects of the particles alone.
Microplastics as vectors of contaminants
This review highlights the emerging role of microplastics as carriers of biological and chemical contaminants in water environments. Researchers note that while microplastic pollution is increasingly well-documented, the interactions between contaminants adsorbed onto microplastic surfaces and aquatic organisms remain poorly understood. The study stresses the need for further investigation into how microplastics may facilitate the transport and bioavailability of pollutants.
Beyond the Surface: Biofilms and Microplastics in Aquatic Systems
This review examines how microbial biofilms that form on microplastic surfaces (the 'plastisphere') influence particle transport, degradation rates, and potential toxicity in aquatic environments, including the role of biofilms in carrying pathogens and antibiotic resistance genes.
Microplastics as vectors of chemical contaminants and biological agents in freshwater ecosystems: Current knowledge status and future perspectives
This review examines how microplastics in freshwater ecosystems act as carriers for chemical pollutants and harmful microorganisms. Researchers found that pollutant concentrations on microplastic surfaces can be up to six times higher than in surrounding water, amplifying exposure risks for aquatic life and potentially humans. The findings highlight that microplastics are not just a pollution problem themselves but also a vehicle that spreads other contaminants through the food web.
Recent advances in the relationships between biofilms and microplastics in natural environments
This review summarizes how microorganisms form biofilms on the surface of microplastics in water, changing the particles' physical properties and helping to spread bacteria and genes across ecosystems. These biofilm-coated microplastics can carry harmful microbes into new environments, raising concerns about waterborne disease transmission and the effectiveness of current water treatment methods.
Enrichment and dissemination of bacterial pathogens by microplastics in the aquatic environment
This review examines how microplastics serve as floating platforms for dangerous bacteria in waterways, harboring pathogens like Vibrio and Pseudomonas at higher densities than surrounding water. Researchers found that bacteria can transfer between microplastic surfaces and water through mechanisms like horizontal gene transfer and chemical signaling. The findings raise concerns that microplastic pollution may be accelerating the spread of waterborne pathogens that threaten both ecosystem and human health.
[Enrichment Characteristics and Ecological Risk Prediction of Pathogens on Typical Microplastic Biofilms].
This study investigated which pathogens preferentially colonize biofilms on different types of microplastic surfaces in aquatic environments and assessed the associated ecological and public health risks. Microplastic biofilms showed selective enrichment of specific pathogen groups compared to surrounding water, with biofilm-forming potential varying by polymer type.
Plastics and Microplastics as Vectors for Bacteria and Human Pathogens
This study reviewed how marine plastic debris serves as a surface for bacterial colonization, including human pathogens, and examined the novel communities forming on plastic surfaces. The research raises public health concerns about microplastics acting as rafts that transport harmful bacteria to new locations, including to seafood and coastal recreational areas.
The Occurrence of Microplastics and the Formation of Biofilms by Pathogenic and Opportunistic Bacteria as Threats in Aquaculture
This review examines how microplastics in aquaculture environments serve as habitats and transport vehicles for pathogenic and opportunistic bacteria, with more than 30 taxa of pathogens detected on plastic-associated biofilms. The study suggests that the combination of plastic persistence, closed aquaculture conditions, and pathogen affinity for plastic surfaces creates a significant threat to aquaculture production and food safety.
Microplastics as vectors of environmental contaminants: Interactions in the natural ecosystems
This review examines how microplastics act as vectors for pathogens, persistent organic pollutants, and heavy metals in marine, freshwater, and terrestrial ecosystems, summarising evidence that these particles damage cell membranes, tissues, and physiological processes in exposed organisms.
The impact of microplastics on small organism dispersal: mechanisms, risks, and research gaps
This review examines how microplastics may influence the dispersal of small organisms, including bacteria, fungi, viruses, and insects, by serving as physical carriers across ecosystems. Researchers describe how biofilms that form on microplastic surfaces can harbor and transport pathogenic microorganisms to new locations. The study identifies this as an underexplored area with significant implications for disease ecology and biosecurity.
Microplastics as Potential Vector of Antibiotics in Aquatic Media: Environmental Implications
This review examined the role of microplastics as vectors for antibiotics in aquatic environments, highlighting how their small size, large surface area, and hydrophobicity enable them to concentrate organic pollutants. Co-exposure of microplastics and antibiotics can enhance bioaccumulation in organisms and amplify environmental risk.
Biofilm formation and its implications on the properties and fate of microplastics in aquatic environments: A review
Researchers reviewed how microplastics in water attract and support communities of bacteria and other microorganisms that form biofilms — living coatings that alter the plastic particles' movement, help them carry pathogens, and affect how toxic chemicals attached to the plastic are absorbed by living things. Understanding this "plastisphere" ecosystem is critical for predicting where microplastics go and how harmful they become.
Selective enrichment of antibiotic resistome and bacterial pathogens by aquatic microplastics
This review found that microplastics in aquatic environments selectively enrich antibiotic-resistant bacteria, resistance genes, and bacterial pathogens in their biofilms, making plastic debris a potential vector for spreading antimicrobial resistance.
