ClearPotentially pathogenic bacteria in the plastisphere from water, sediments, and commercial fish in a tropical coastal lagoon: An assessment and management proposal
Researchers examined the types of potentially harmful bacteria living on microplastics found in water, sediments, and commercial fish in a tropical coastal lagoon. They identified several pathogenic species colonizing the microplastic surfaces, which could pose risks when contaminated fish are consumed by humans. The study proposes management strategies to reduce the public health threat of microplastic-associated pathogens in fisheries.
In Situ Investigation of Plastic-Associated Bacterial Communities in a Freshwater Lake of Hungary
Researchers investigated plastic-associated bacterial communities on microplastic surfaces in a Hungarian freshwater lake, finding that the plastisphere harbored distinct microbial communities compared to surrounding water, including potential pathogens and plastic-degrading bacteria.
Increasing microplastics pollution: An emerging vector for potentially pathogenic bacteria in the environment
Researchers collected microplastics from a river basin in Turkey and found that disease-causing bacteria, including Salmonella, E. coli, and Staphylococcus, readily form colonies on plastic particle surfaces. This means microplastics floating in water can act as tiny rafts carrying harmful bacteria, potentially increasing infection risks when contaminated water is used for drinking or recreation.
Viral diversity and potential environmental risk in microplastic at watershed scale: Evidence from metagenomic analysis of plastisphere
Metagenomic analysis of plastisphere communities on microplastics collected from five freshwater sites revealed diverse viral communities including phages and potential animal pathogens, with plastic-associated viromes differing from those in surrounding water. The study identifies microplastics as previously overlooked carriers of viral diversity and potential environmental health risks in aquatic ecosystems.
Characteristics of microplastic pollution and analysis of colonized-microbiota in a freshwater aquaculture system.
Researchers found microplastics averaging 288.53 items per liter in freshwater aquaculture ponds in China, dominated by transparent fibers and cellulose particles, and discovered that bacterial communities on microplastic surfaces had significantly higher species richness and diversity than those in surrounding water. The plastisphere communities were enriched with Proteobacteria, including cellulose-degrading and potentially pathogenic species.
Freshwater plastispheres as a vector for foodborne bacteria and viruses
Researchers submerged common plastic types in a Norwegian river and analyzed the microbial communities that colonized their surfaces across different seasons and locations. The study detected potentially harmful bacteria including E. coli and Listeria monocytogenes, as well as norovirus and adenovirus, on the plastic surfaces. These findings suggest that microplastics in freshwater systems could serve as vectors for transporting foodborne pathogens, particularly when contaminated water is used for irrigation.
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.
Total coliform and Escherichia coli in microplastic biofilms grown in wastewater and inactivation by peracetic acid
Researchers found that microplastics support the growth of fecal indicator bacteria including E. coli in biofilms, and that these biofilm communities are more resistant to disinfection by peracetic acid than free-floating cells. The findings support concerns that microplastics act as vectors for pathogens and complicate wastewater disinfection.
Foodborne pathogens in the plastisphere: Can microplastics in the food chain threaten microbial food safety?
This review examines the potential for microplastics to act as vectors for foodborne pathogens in the food chain, synthesizing current evidence on pathogen attachment to the plastisphere, the effects of microplastics on bacterial virulence and evolution, and the implications for simultaneous uptake of microplastics and pathogens in the human gut.
Survival of human pathogens bound to microplastics during transfer through the freshwater-marine continuum: from wastewater discharge to the beach
Researchers tracked survival of E. coli, E. faecalis, and P. aeruginosa colonizing polyethylene microplastics as particles were transferred through a series of mesocosms simulating downstream transport from wastewater effluent through freshwater, estuary, seawater, and beach sand. All three pathogens survived the full environmental transition sequence in the plastisphere, with higher bacterial concentrations on microplastics than on glass controls, though die-off rates did not differ by substrate, demonstrating microplastics' potential to extend pathogen persistence across environmental boundaries.
Ecotoxicological and health implications of microplastic-associated biofilms: a recent review and prospect for turning the hazards into benefits
This review examined the ecological and health implications of biofilms that form on microplastics, discussing how these plastisphere communities can harbor pathogens and alter microplastic properties, while also exploring potential beneficial applications of microplastic-associated biofilms.
Exploiting microplastics and the plastisphere for the surveillance of human pathogenic bacteria discharged into surface waters in wastewater effluent
Researchers placed small plastic particles in rivers upstream and downstream of a wastewater treatment plant and found that disease-causing bacteria, including E. coli and Klebsiella, quickly formed biofilms on them within 24 hours. These biofilms carried antibiotic resistance genes and virulence factors, showing that microplastics in waterways can serve as floating platforms for dangerous bacteria that pose risks to human health.
Interactions between microplastics and microbiota in a One Health perspective
This review examines how microplastics interact with microbial communities across human, animal, and environmental settings using a One Health framework. Microplastics disrupt the normal balance of microbiota in the gut, soil, and water, and serve as surfaces where harmful bacteria and antibiotic resistance genes accumulate and spread. The authors argue that understanding these microplastic-microbe interactions across all domains of life is essential for protecting both ecosystem and human health.
Long-term study of the bacterial colonization of polypropylene microplastics in a freshwater lake by optical and molecular methods
This long-term study monitored bacterial colonization on polypropylene microplastic surfaces in a freshwater environment over an extended period, tracking how the plastisphere community develops and changes over time. Long-term data on plastisphere development reveals that microplastic surfaces support distinct and evolving microbial communities that differ from surrounding water, potentially harboring pathogenic or antibiotic-resistant bacteria.
Microplastics in Aquatic Environments
This review summarizes the current state of microplastic research in aquatic environments, covering the plastisphere — the microbial community that colonizes plastic surfaces — and the ways microplastics interact with other aquatic organisms. The paper highlights microplastics as a growing ecological concern that affects food webs and ecosystem processes.
Plastisphere in freshwaters: An emerging concern
This review introduced the concept of the freshwater plastisphere - the microbial community colonizing plastic debris in rivers and lakes - and found that freshwater plastisphere communities are compositionally distinct from marine ones and from ambient water microbiomes, with implications for pathogen dispersal and plastic degradation in inland waters.
Microplastics in agriculture – a potential novel mechanism for the delivery of human pathogens onto crops
This paper explores how microplastics in agricultural soil could carry human pathogens onto food crops, creating a new route for foodborne illness. Plastic surfaces quickly become colonized by bacteria, including dangerous species from wastewater and animal manure, forming a community called the plastisphere. Since microplastics can stick to ready-to-eat crops and are difficult to wash off, they could transfer harmful bacteria directly to people through the food supply.
From wastewater discharge to the beach: Survival of human pathogens bound to microplastics during transfer through the freshwater-marine continuum
Researchers investigated how human pathogens survive on microplastic surfaces as they travel from wastewater treatment plants through freshwater into marine environments. They found that the biofilm environment on plastic surfaces helped bacteria like E. coli and Enterococcus faecalis persist longer during transitions between water types compared to bacteria in the surrounding water. The study suggests that microplastics may facilitate the environmental spread of pathogens by providing a protective habitat during transport.
Environmental Health Impact of Plastisphere
This review examines the growing body of research on plastisphere ecosystems in aquatic environments including rivers, lakes, and estuaries, discussing microbial community composition on plastic surfaces and the ecological consequences for freshwater biodiversity and function.
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.
Lacustrine plastisphere: Distinct succession and assembly processes of prokaryotic and eukaryotic communities and role of site, time, and polymer types
Researchers investigated how microbial communities colonize different types of microplastic polymers in freshwater lakes. The study found that bacteria and single-celled organisms follow distinct assembly patterns on microplastic surfaces, with colonization time, location, and polymer type all influencing community composition. These findings suggest microplastics serve as carriers that can promote microbial spread in aquatic environments.
Bioremediation of water polluted with microplastics by bacteria isolated from the environment
This dissertation examined bacteria isolated from the plastisphere — the microplastic surface environment — for their ability to bioremediate microplastic pollution in water. The research combined ecotoxicity testing with bioremediation trials, finding that certain plastisphere bacteria show potential for breaking down microplastics in aquatic environments.
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.
Bacterial community structure of water, sediment and microplastics in Poyang Lake wetland.
This study compared the bacterial communities living on four types of microplastics (film, foam, fiber, and fragment) in Poyang Lake wetland in China against the bacterial communities in the surrounding water and sediment. The microplastic surfaces hosted distinct microbial communities that differed from both the water and sediment, with foam microplastics supporting the least diverse communities. This "plastisphere" research is important because the unique bacteria colonizing plastic surfaces could spread pathogens or alter nutrient cycles in freshwater wetland ecosystems.
