ClearCo-existence of polyethylene microplastics and tetracycline on soil microbial community and ARGs
This study examined how polyethylene microplastics and the antibiotic tetracycline interact in soil. When present together, they altered soil microbial communities and increased the abundance of antibiotic resistance genes more than either contaminant alone. The findings raise concerns that microplastics in agricultural soil may worsen the spread of antibiotic resistance, a growing public health challenge.
The combined effect of microplastics and tetracycline on soil microbial communities and ARGs
Researchers studied how simultaneous exposure to microplastics and tetracycline affects soil microbial communities, finding that the combination disrupted microbial diversity, altered functional gene expression, and promoted horizontal transfer of antibiotic resistance genes beyond the effects of either pollutant alone.
Microplastics combined with tetracycline in soils facilitate the formation of antibiotic resistance in the Enchytraeus crypticus microbiome
Soil invertebrates (Enchytraeus crypticus) were exposed to microplastics and tetracycline alone and in combination; combined exposure promoted greater shifts in gut microbiome composition and higher levels of antibiotic resistance genes than either stressor alone, suggesting microplastics exacerbate antibiotic resistance spread in soil.
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.
Characteristics of tetracycline antibiotic resistance gene enrichment and migration in soil–plant system
This review examines how tetracycline antibiotic resistance genes spread through soil and into plants, with microplastics identified as one of the factors that accelerate this process. Resistance genes can transfer from soil bacteria into plant tissues through root absorption, ultimately accumulating in edible parts like leaves and fruits. This means microplastic-contaminated agricultural soil could help spread antibiotic resistance to humans through the food they eat.
Tracking antibiotic resistance genes in microplastic-contaminated soil
Researchers used metagenomics to track antibiotic resistance genes in agricultural soils with long histories of plastic mulch use across eight Chinese provinces, identifying 204 subtypes of resistance genes alongside thousands of mobile genetic elements, demonstrating that microplastic-contaminated soils are significant reservoirs for antibiotic resistance spread.
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.
Varying characteristics and driving mechanisms of antibiotic resistance genes in farmland soil amended with high-density polyethylene microplastics
A 60-day soil experiment found that high-density polyethylene microplastics containing phthalate additives significantly enhanced antibiotic resistance gene abundance in farmland soil compared to plastics without phthalates, identifying phthalate release as a key driver of microplastic-associated ARG enrichment.
Metagenomic analysis of effects of oxytetracycline and copper on antibiotic resistance genes and associated pathogenic hosts in swine manure compost
Metagenomic analysis of swine manure compost showed that antibiotics and copper promoted antibiotic resistance genes and their potential transfer to human pathogens. This research is not directly about microplastics but is relevant because microplastics in sewage sludge and manure also carry and disseminate antibiotic resistance genes.
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.
Polyvinyl chloride promoted the dissemination of antibiotic resistance genes in Chinese soil: A metagenomic viewpoint
Researchers conducted a nationwide metagenomic study across 20 provinces in China, adding polyvinyl chloride (PVC) microplastics to soils with varying physical and chemical properties and evaluating impacts on bacterial community structure and antibiotic resistance gene (ARG) abundance. Structural equation modelling revealed that PVC microplastics significantly altered soil microbiomes and promoted ARG dissemination, highlighting plastic pollution as a driver of antimicrobial resistance spread in agricultural soils.
Sources, interactions, influencing factors and ecological risks of microplastics and antibiotic resistance genes in soil: A review
Microplastics in soil serve as hotspots for antibiotic resistance genes, with the plastisphere — the microbial community colonizing plastic surfaces — facilitating horizontal gene transfer of resistance markers. Key factors driving this interaction include microplastic properties, soil chemistry, and agricultural practices, though research in soil environments is still at an early stage compared to aquatic systems.
Absence of synergistic effects between microplastics and copper ions on the spread of antibiotic resistance genes within aquatic bacteria at the community level
Researchers examined whether microplastics and copper ions act synergistically to spread antibiotic resistance genes (ARGs) within aquatic bacterial communities in natural environments. At the community level, no significant synergistic effect was observed, suggesting that combined microplastic and copper contamination does not amplify ARG dissemination beyond the individual effects of each stressor.
Antibiotics and Antibiotic Resistance Genes in Animal Manure – Consequences of Its Application in Agriculture
This review examines how antibiotic resistance genes spread from animal manure used as fertilizer into agricultural soil and food crops. The widespread use of antibiotics in livestock creates resistant bacteria that survive in manure and can transfer their resistance to soil microbes and eventually to pathogens that affect humans. While focused on antibiotics rather than microplastics, this is relevant because microplastics in soil can also carry and spread antibiotic-resistant bacteria, compounding the risk to human health.
Effects of agricultural inputs on soil virome-associated antibiotic resistance and virulence: A focus on manure, microplastic and pesticide
Researchers studied how agricultural inputs including manure, microplastics, and pesticides affect virus communities in soil and their potential to carry antibiotic resistance genes. They found that manure application significantly increased both viral diversity and the abundance of resistance and virulence genes carried by viruses. The study reveals that soil viruses may play a previously underappreciated role in spreading antibiotic resistance through agricultural ecosystems.
Soil 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.
Polyvinyl chloride microplastics disseminate antibiotic resistance genes in Chinese soil: A metagenomic analysis
Researchers used metagenomic analysis to investigate how polyvinyl chloride microplastics affect the spread of antibiotic resistance genes in Chinese soils. They found that PVC microplastics significantly influenced soil bacterial community composition and increased the abundance of certain antibiotic resistance genes. The study raises concerns that microplastic contamination in agricultural soils may accelerate the dissemination of antimicrobial resistance.
Multiomics analysis of the effects of manure-borne doxycycline combined with oversized fiber microplastics on pak choi growth and the risk of antibiotic resistance gene transmission
Researchers studied how oversized fiber microplastics combined with the antibiotic doxycycline from manure affect pak choi growth and soil health. They found that the antibiotic had a more pronounced negative impact than the microplastics, but slender-fiber microplastics amplified the harmful effects on plant growth and altered soil metabolites. The study raises concerns about antibiotic resistance gene transmission through the combined presence of microplastics and antibiotics in agricultural soils.
Integrating metagenomics analysis and machine learning to identify drivers of antibiotic resistance genes abundance in microplastic-contaminated soil
Researchers integrated global soil metagenomic datasets with machine learning to identify which microplastic properties, climatic variables, and soil characteristics best predict antibiotic resistance gene (ARG) abundance in microplastic-contaminated soils. Microplastic type and surface area were stronger drivers of ARG enrichment than climate or soil chemistry, pointing to plastic material properties as key targets for antibiotic resistance management.
Microplastics reduced the natural attenuation of antibiotic resistance genes in fertilized soils
This study found that microplastics in fertilized farm soil slowed down the natural breakdown of antibiotic resistance genes, meaning these dangerous genes persisted longer in the environment. The microplastics altered soil bacterial communities and promoted the survival of potentially harmful bacteria like E. coli and Salmonella that carry resistance genes. This raises concerns that agricultural plastic pollution could contribute to the growing global problem of antibiotic resistance.
Dual roles of polystyrene nanoplastics in reshaping antibiotic resistance genes dynamics in soil–plant systems: Highlighting shifts in specific hosts and functions
Researchers found that polystyrene nanoplastics elevated antibiotic resistance gene abundance in soil by 11–18% while simultaneously hindering ARG transfer into plant root tissues, and stimulated the proliferation of key pathogenic ARG-carrying bacteria including Mycobacterium tuberculosis.
Effects of freeze-thaw dynamics and microplastics on the distribution of antibiotic resistance genes in soil aggregates
Researchers investigated how freeze-thaw cycles and microplastics together affect the spread of antibiotic resistance genes in soil. The study found that repeated freezing and thawing significantly increased antibiotic resistance genes across different soil particle sizes. Interestingly, the presence of polyethylene microplastics actually reduced some of the resistance gene increases caused by freeze-thaw, suggesting a complex interaction between these two environmental stressors.
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.
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.
