Microplastics (MPs) and antibiotic resistance genes (ARGs) pose significant challenges to the One Health framework due their intricate multifaceted ecological environmental impacts. However, understanding of how MP properties influence ARG prevalence in mariculture sediments remains limited. Herein, polystyrene (PS) polyvinyl chloride (PVC) MPs with different sizes (20-120 μm 0.5-2.0 mm) were selected evaluate impacts underlying mechanisms driving ARGs dissemination. The results showed that PS PVC increased relative abundance by 1.41-2.50-fold 2.01-2.84-fold, respectively, compared control, particularly high-risk genes. polymer type effect was identified as more influential than size sediment resistome evolution. shifted microbial community assembly from stochastic deterministic processes, thus enriching host pathogens. Furthermore, highly hydrophobic not only recruited bacteria colonization but also facilitated exchange within plastisphere. exogenous additives released (e.g., heavy metals, bisphenol A, tridecyl ester) particles synergistically promoted conjugative transfer inducing oxidative stress enhancing cell membrane permeability. These findings revealed characteristics spread marine benthic ecosystems, underscoring importance mitigating pollution maintain ecosystem health, prevent zoonotic diseases, balance global health.

Microplastic pollution contributes to the rise of antibiotic-resistance. Everyday items like food containers, water bottles, clothing, and cosmetics can increase people's resistance antibiotics. Microplastics in environment serve as a suitable substrate for production "antibiotic-resistant genes" (ARGs). These genes are protected by bacterial chromosomes, phages, plasmids, which biological vectors capable spreading transferring antibiotic-resistance humans, thereby reducing their ability fight infections. In this study, we reviewed several articles that evaluated abundance ARGs changes expression different environments. were observed upon exposure antibiotics such tetracycline, sulfamethoxazole, macrolides, others, well microplastics, nanoplastics, or combination both. To assess impact these stressors on ARG abundance, compiled data from various studies using heatmaps tables abundances tissues By synthesizing information, aimed identify upregulated downregulated response each stressor. Our findings provide insights into potential risks posed environmental pollutants underscore importance understanding dynamics stressors.

Microplastics (MPs) in aquatic environments easily support biofilm development, which can interact with other environmental pollutants and act as harbors for microorganisms. Recently, numerous studies have investigated the fate behavior of MP biofilms environments, highlighting their roles spread pathogens antibiotic resistance genes (ARGs) to organisms new habitats. The prevalence effects been extensively recent decades, behaviors need be synthesized systematically updated information. This review aims reveal development its interactions antibiotics, ARGs, environments. Recent research has shown that adsorption capabilities MPs antibiotics are enhanced after formation, is biased towards chemisorption. ARGs microorganisms, especially pathogens, selectively enriched significantly different from those surrounding waters. promotes propagation through horizontal gene transfer (HGT) vertical (VGT) induces emergence antibiotic-resistant resulting increased threats ecosystems human health.

Micro-interfacial behavior of antibiotic-resistant bacteria and antibiotic resistance genes in the soil environment: A review

Environment International, Год журнала: 2024, Номер 191, С. 108972 - 108972

Overutilization and misuse of antibiotics in recent decades markedly intensified the rapid proliferation diffusion antibiotic resistance genes (ARGs) within environment, thereby elevating ARGs to status a global public health crisis. Recognizing that soil acts as critical reservoir for ARGs, environmental researchers have made great progress exploring sources, distribution, spread soil. However, microscopic state micro-interfacial behavior remains inadequately understood. In this study, we reviewed behaviors antibiotic-resistant bacteria (ARB) porous media, predominantly including migration-deposition, adsorption, biofilm formation. Meanwhile, proliferation, degradation were identified primary soil, with component serving significant determinant. Our work contributes further comprehension microstates processes ARB environments offers theoretical foundation managing mitigating risks associated ARG contamination.
