Enrichment and dissemination of bacterial pathogens by microplastics in the aquatic environment
Summary
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.
Microplastic pollution and associated impacts in the aquatic environment are spreading at an alarming rate worldwide. Plastic waste is increasing in the environment, and microplastics (MPs) are becoming a growing issue because they serve as vectors for pathogen transmission. This is the first comprehensive review that specifically addresses MPs as a source and vector of pathogenic bacteria, mainly associated with genera Vibrio, Pseudomonas, Acinetobacter, and so on, which are discovered to be more abundant on the aquatic plastisphere than that in the surrounding wastewater, freshwater, and marine water ecosystems. The horizontal gene transfer, chemotaxis, and co-selection and cross-selection could be the potential mechanism involved in the enrichment and dissemination of bacterial pathogens through the aquatic plastisphere. Further, bacterial pathogens through aquatic plastisphere can cause various ecological and human health impacts such as disrupted food chain, oxidative stress, tissue damages, disease transmission, microbial dysbiosis, metabolic disorders, among others. Last but not least, future research directions are also described to find answers to the challenging questions about bacterial pathogens in the aquatic plastisphere to ensure the integrity and safety of ecological and human health.

Potential impact of marine-derived plastisphere as a Vibrio carrier on marine ecosystems: Current status and future perspectives
This review examines how microplastics in the ocean serve as floating platforms for Vibrio bacteria, which are significant pathogens threatening aquaculture and marine ecosystem health. Researchers found that the so-called plastisphere, the microbial community that colonizes plastic surfaces, can enhance the survival and spread of these harmful bacteria. The study highlights a concerning link between plastic pollution and the potential amplification of waterborne disease risks.
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.
An Exploratory Review of Microplastic Pollution, Associated Microbiomes and Pathogens in Water
This review analyzes over a decade of research on microplastic pollution in surface waters across five continents, focusing on the microorganisms that colonize plastic surfaces. Researchers found that microplastics serve as floating habitats for bacteria, including potential human pathogens and antibiotic-resistant strains. The study highlights that microplastic pollution poses a dual threat by both contaminating water and providing a vehicle for harmful microbes to spread.
Microplastic-associated pathogens and antimicrobial resistance in environment
This review examines how microplastics in the environment act as surfaces for disease-causing bacteria and antibiotic-resistant microbes to colonize and spread. Researchers found that microplastics can carry pathogens and facilitate the transfer of antimicrobial resistance genes between bacteria in water systems. The findings raise concerns that microplastic pollution may be contributing to the growing global challenge of antibiotic resistance.
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.
