ClearSoil plastispheres as hotspots of antibiotic resistance genes and potential pathogens
Researchers investigated microbial communities and antibiotic resistance genes on microplastic surfaces (the plastisphere) in soil environments. They found that plastispheres harbor enriched levels of potential pathogens and antibiotic resistance genes compared to surrounding soil, and that adding manure or increasing temperature and moisture further amplified these concerning microbial communities.
The formation of specific bacterial communities contributes to the enrichment of antibiotic resistance genes in the soil plastisphere
Researchers used metagenomic approaches to study how microplastic surfaces in soil become enriched with antibiotic resistance genes through the formation of specific bacterial communities. The study tested three types of microplastics at two particle sizes and found that antibiotic resistance gene abundances significantly increased in the plastisphere compared to surrounding soil. Evidence indicates that microplastics in soil may serve as hotspots for the spread of antibiotic resistance.
Antibiotic resistance in plastisphere
Researchers reviewed antibiotic resistance in the plastisphere — the microbial community colonizing plastic surfaces in aquatic environments — finding that plastic properties and aging influence the enrichment and horizontal transfer of antibiotic resistance genes, and that aged microplastics pose elevated risks due to increased adsorption of resistant bacteria.
Interaction of Microbes with Microplastics and Nanoplastics in the Agroecosystems—Impact on Antimicrobial Resistance
This review examines how microplastics and nanoplastics in agricultural soil serve as hotspots for spreading antibiotic resistance genes between bacteria. The plastic particles provide surfaces where bacteria exchange genetic material, potentially accelerating the spread of drug-resistant microbes. This is a public health concern because resistant bacteria from farm soil can enter the food chain and make infections harder to treat.
Microplastic biofilm as hotspots of antibiotic resistance genes and potential pathogens
This review examined how microplastic biofilms—the plastisphere—serve as hotspots for antibiotic resistance gene (ARG) accumulation and potential pathogen enrichment. The authors described mechanisms by which microplastic surfaces promote horizontal gene transfer and bacterial community shifts that favor ARG-carrying strains, raising concern that microplastics accelerate the spread of antibiotic resistance in aquatic environments.
Microbial Bioindicators for Monitoring the Impact of Emerging Contaminants on Soil Health in the European Framework
This study analyzed soil samples from across EU countries to investigate how microplastics may help spread antibiotic resistance. Researchers found that bacterial communities on microplastic surfaces can harbor antibiotic resistance genes, and the plastisphere environment facilitates the transfer of these genes between microbes. The findings suggest microplastics in soil could serve as hotspots for antibiotic resistance, posing potential risks to human health.
Plastisphere as a Vector for Pathogenic Microbes and Antibiotic Resistance
This review examines how the plastisphere, the microbial community that colonizes plastic surfaces, serves as a vector for pathogenic bacteria and antibiotic resistance genes. Researchers found that microplastics can adsorb antibiotics and facilitate higher rates of plasmid transfer among bacteria, with potentially pathogenic species carrying multi-drug resistance genes identified on plastic surfaces.
Insight into combined pollution of antibiotics and microplastics in aquatic and soil environment: Environmental behavior, interaction mechanism and associated impact of resistant genes
This review examines the combined pollution created when microplastics absorb antibiotics in water and soil environments. Researchers found that microplastics can concentrate antibiotics on their surfaces, and this combination promotes the spread of antibiotic-resistant genes in microbial communities. The study highlights that the interaction between these two emerging pollutants may pose greater environmental and health risks than either one alone.
Some Microbiological Characteristics of the Biofilm on the Surface of Pre-Production Pellets of Polypropylene Microplastics after Short Exposure in Soil
After 30 days of burial in residential soil, polypropylene microplastic pellets developed distinct surface biofilms with microbial communities different from those on quartz sand and from the surrounding soil. The colonization of microplastic surfaces by soil microbes (forming a 'plastisphere') is significant because these biofilms can alter how microplastics move through soil and may carry pathogens or antibiotic resistance genes into the environment.
Microplastisphere antibiotic resistance genes: A bird's-eye view on the plastic-specific diversity and enrichment
Microplastics in the environment act as surfaces for microbial communities called microplastispheres, which this review finds are enriched with antibiotic resistance genes (ARGs). The type of plastic, surrounding water chemistry, and co-occurring pollutants all influence which resistance genes accumulate, raising concern that microplastics could be spreading antibiotic resistance through aquatic environments worldwide.

Selection for antimicrobial resistance in the plastisphere
This review examines how microplastics in the environment may contribute to the spread of antimicrobial resistance by providing surfaces where bacteria, antibiotics, and resistant genes converge. Researchers describe several mechanisms by which the microbial communities living on microplastics, known as the plastisphere, could accelerate horizontal gene transfer of resistance traits. The study highlights an emerging concern at the intersection of plastic pollution and the global antimicrobial resistance crisis.
Effect of polyethylene microplastics on antibiotic resistance genes: A comparison based on different soil types and plant types
This study compared how polyethylene microplastics affect antibiotic resistance genes across different soil types and found that contaminated soils and the presence of certain plants influenced which resistance genes proliferated. The results suggest that microplastics in agricultural soil can help spread antibiotic resistance, which is a serious concern for human health because resistant bacteria can enter the food supply through crops.
Antibiotic sorption onto MPs in terrestrial environment: a critical review of the transport, bioaccumulation, ecotoxicological effects and prospects
This review examines how microplastics in soil absorb and transport antibiotics, creating complex pollutants that can spread antibiotic resistance genes through the environment. When antibiotic-carrying microplastics are taken up by plants or soil organisms, the resistance genes can eventually reach humans through the food chain. The authors highlight the need for better strategies to reduce microplastic contamination in soil to help slow the growing crisis of antibiotic resistance.
An Overview of Antibiotic Resistance and Abiotic Stresses Affecting Antimicrobial Resistance in Agricultural Soils
This systematic review found that soil contaminants from organic and chemical fertilizers, heavy metals, hydrocarbons, and untreated sewage sludge significantly promote antimicrobial resistance by increasing the abundance of antibiotic resistance genes in agricultural soils. Abiotic stresses like salinity and drought further amplify this effect. The findings connect to microplastic research because microplastics have been shown to serve as vectors for antibiotic-resistant bacteria and resistance genes in soil environments.
Fate and abundance of antibiotic resistance genes on microplastics in facility vegetable soil
This study found that microplastics in vegetable farm soils serve as hotspots for antibiotic resistance genes (ARGs), potentially amplifying the spread of antibiotic-resistant bacteria in agricultural environments. The co-presence of microplastics and ARGs in food-producing soils raises concerns about pathways for resistance genes to enter the food chain.
Alteration of microbial mediated carbon cycle and antibiotic resistance genes during plastisphere formation in coastal area
Researchers investigated how microplastic surfaces in coastal environments develop biofilm communities, known as the plastisphere, and whether these biofilms enrich antibiotic resistance genes. The study found that incubation time, habitat type, and microplastic aging state all significantly influenced biofilm composition, and that aged microplastics accumulated more antibiotic resistance genes than new ones, suggesting microplastics may serve as vectors for spreading resistant bacteria.

This review examined the role of microplastics as carriers of antibiotic resistance genes (ARGs) and pathogenic bacteria, analyzing how plastisphere biofilms concentrate and spread AMR through air, water, and soil environments. The evidence supports MPs as global vectors for antimicrobial resistance dissemination with implications for human health.
Microplastic aging mediates bacterial and antibiotic resistance gene composition in plastisphere and the associated soil solution
Researchers ran a microcosm experiment comparing how pristine versus aged microplastics influenced bacterial communities and antibiotic resistance gene (ARG) composition in the plastisphere and surrounding soil solution. Aged MPs enriched distinct ARGs and microbial taxa compared to pristine MPs, suggesting MP weathering intensifies the spread of antibiotic resistance in soils.
The combined effect of microplastics and tetracycline on soil microbial communities and ARGs

Microplastics and their role in the emergence of antibiotic resistance in bacteria as a threat for the environment
Researchers reviewed how microplastics act as breeding grounds for antibiotic-resistant bacteria by providing surfaces where bacteria can swap resistance genes with each other — a process called horizontal gene transfer. This dual threat of plastic pollution and antibiotic resistance is compounding into a significant global public health crisis.
[Influencing Factors and Mechanisms of Antibiotic Resistance Gene Enrichment by Microplastics in the Environment].
This review examines how microplastics in the environment serve as carriers for antibiotic resistance genes, enriching and spreading resistant bacteria across air, soil, water, and sediments. Researchers found that the type, surface characteristics, and aging of microplastics all influence how effectively they accumulate resistance genes and facilitate horizontal gene transfer. The findings highlight the need to consider microplastics as an important vector in the environmental spread of antibiotic resistance.
