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.
Microplastics (MPs) in aquatic ecosystems readily promote biofilm formation, creating the plastisphere, a dynamic interface that interacts with environmental pollutants and acts as a reservoir for microorganisms. Recent studies emphasize the plastisphere's contribution to the spread of pathogens, antibiotic-resistant genes (ARGs), and antimicrobial resistance (AMR) within aquatic organisms and across diverse environments, a phenomenon collectively called the 'Plastiome'. Although the prevalence and effects of the plastisphere have been studied extensively, a systematic synthesis of updated insights into the behavior of the plastiome is urgently needed. This review explores the development and behavior of plastics, focusing on its interactions with ARGs and pathogens within aquatic ecosystems. Microplastics selectively enrich ARGs and pathogenic microorganisms, fostering unique microbial communities distinct from those in surrounding waters. The plastiome facilitates horizontal ARG propagation, increasing the quantity of antibiotic-resistant pathogens and presenting substantial risks to the hydrosphere and public health. Additionally, key research opportunities are identified and strategies are recommended to advance our understanding of plastiome-driven antibiotic resistance in aquatic environments.

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.
Microplastics and the plastisphere: hidden players of global antimicrobial resistance
AI summary Read the abstract
This review summarizes existing research on tiny plastic particles (microplastics) in the environment that become coated with microbes, forming a "plastisphere." Studies show these coatings often carry more antibiotic resistance genes than surrounding water or soil, and may help spread resistant microbes between environments, though gaps remain in understanding the exact mechanisms.

AI summary Read the abstract
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.

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.
