ClearPotential 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.
