Are microplastic particles a hotspot for the spread and the persistence of antibiotic resistance in aquatic systems?
AI summary Read the abstract
This review explores whether microplastic particles in water could serve as hotspots for antibiotic-resistant bacteria. Researchers found that microplastics host a unique microbial biofilm called the "plastisphere" that differs from surrounding water communities and may promote the survival and spread of resistant organisms. The study suggests that microplastics could act as carriers of antibiotic resistance genes, posing a potential threat to both environmental and human health.
In the last decade, the study of the origin and fate of plastic debris received great attention, leading to a new and broad awareness of the hazard represented by these particles for the environment and the biota. At the same time, the scientific consideration on the leading role of the environment regarding the spread of antibiotic resistant bacteria (ARB) increased. Both, microplastic particles (MPs) and ARB share pollution sources and, in aquatic systems, MPs could act as a novel ecological niche, favouring the survival of pathogens and ARB. MPs can host a specific microbial biofilm, referred to as plastisphere, phylogenetically different from the surrounding planktonic microbial community and from the biofilm growing on other suspended particles. The plastisphere can influence the overall microbiome of a specific habitat, by introducing and supporting different species and by increasing horizontal gene transfer. In this review we collect and analyse the available studies coupling MPs and antibiotic resistance in water, highlighting knowledge gaps to be filled in order to understand if MPs could effectively act as a carrier of ARB and antibiotic resistance genes, and pose a real threat to human health.

Microplastics: Hidden drivers of antimicrobial resistance in aquatic systems
AI summary Read the abstract
This review examines how microplastics in aquatic environments serve as surfaces for biofilm formation, creating what researchers call the 'plastisphere,' which can harbor antibiotic-resistant bacteria and pathogens. Evidence indicates that microplastics facilitate the spread of antimicrobial resistance genes through water systems, potentially affecting both aquatic organisms and human health. The findings underscore microplastics as an overlooked driver of antibiotic resistance in waterways.

This review examines how microplastics serve as a new ecological niche for antibiotic-resistant bacteria in aquatic environments, creating what researchers call the plastisphere. Microplastics interact with heavy metals, antibiotics, and other pollutants while migrating through water systems and food chains, potentially accelerating the spread of antibiotic resistance genes. The study highlights the plastisphere as a hotspot for resistance gene transfer, posing threats to both human health and urban ecosystems.
Microplastic-mediated antimicrobial resistance in aquatic environments: plastisphere dynamics, ecological risks, and mitigation strategies
AI summary Read the abstract
Tiny plastic particles floating in water aren't just pollution—they act like rafts where bacteria gather and swap genes that make them resistant to antibiotics, potentially making infections harder to treat. This review paper rounds up existing research on how this happens and compares different water treatment methods (like filtration and chemical treatments) that could remove both the plastics and the resistant bacteria at once. The takeaway: tackling microplastic pollution in our water systems may be an important, underappreciated tool for slowing the spread of antibiotic-resistant infections.

This review examined how microplastic particles become colonized by diverse microbial communities in aquatic environments, forming the so-called plastisphere. The research highlights that microplastics create novel ecological niches and may facilitate the spread of pathogens and antibiotic resistance genes in freshwater and marine systems.
The Plastisphere Resistome: A Systematic Review of Antibiotic Resistance Genes and Resistant Bacteria on Microplastics
AI summary Read the abstract
This systematic review examines whether microplastic-associated biofilms harbor higher levels of antibiotic-resistant bacteria compared to surrounding environments. If microplastics act as hotspots for antibiotic resistance genes, they could spread drug-resistant bacteria through water systems, posing a serious concern for human health and the effectiveness of antibiotics.
