Microbial interactions form microfood webs, crucial for ecological functions. The steady state of these shaped by cooperation and competition among trophic levels, prevents pathogen proliferation invasion, maintaining soil health. Combined pollutants pose a widespread environmental issue, exerting significant pressure on webs. However, understanding how webs respond to combined in plastispheres, an emerging niche, remains limited. This study explores bacteria, fungi, protists, examining their effects potential pathogens three types amended with Cu or disinfectant, along using microcosm experiment. Pollutant exposure disrupts trophic-level through bottom-up top-down regulation soils respectively. Microfood web network topology parameters prove more sensitive pollutant stress than indicators from single community composition. causes greater disruption the (Cu didecyl dimethylammonium chloride (DDAC)). Plastisphere reinforces negative impacts network, escalating pathogenic bacteria. Overall, this deepens our responses under plastispheres provides valuable insights health risk assessments pollutants.

The rising spread of antibiotic resistance is a global concern, but the pathways dissemination within soil ecosystems remain poorly understood. Here, we quantified occurrence genes (ARGs) in gut microbiomes collembolans (Folsomia candida) under pesticide stress (zinc thiazole, ZT) and analyzed trophic transfer ARGs to predatory mites (Hypoaspis aculeifer), natural predators collembolans. High throughput quantitative PCR was used quantify ARGs, whereas were characterized using 16S rRNA gene amplicon sequencing, potential pathogens identified. Our results revealed that ZT exposure significantly elevated abundance (e.g., AAC(6')-Ir) collembolan microbiomes. With increase prey microbiomes, an mite observed through transfer. Mobile genetic elements (MGEs) contribute transmission this food chain. Additionally, co-occurrence analysis indicated strong association between resistomes pathogens, such as Brevundimonas diminuta, mites. Overall, our study provides evidence for collembolan-predatory chain following exposure, which important understanding broader dynamics spreading ecosystems.
