Eco-Environment & Health, Journal Year: 2025, Volume and Issue: unknown, P. 100136 - 100136

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.

Abstract Background Antibiotics and microplastics are two major aquatic pollutants that have been associated to antibiotic resistance selection in the environment considered a risk human health. However, little is known about interaction of these at environmental concentrations response microbial communities plastisphere sub-lethal pollution. Here, we describe bacterial dynamics underlying this surface water bacteria community, resistome mobilome level using combination methods (next-generation sequencing qPCR), targets (16S rRNA gene, pre-clinical clinical class 1 integron cassettes metagenomes), technologies (short long read sequencing), assembly approaches (non-assembled reads, genome assembly, bacteriophage plasmid assembly).

Microplastics as vectors for antibiotic resistance genes and their implications for gut 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.

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.
