Microplastic (MP) pollution is a rapidly growing global environmental concern that has led to the emergence of new compartment, plastisphere, which hotspot for accumulation antibiotic resistance genes (ARGs) and human bacterial pathogens (HBPs). However, studies on effects long-term organic fertilizer application dispersal ARGs virulence factor (VFGs) in plastisphere farmland soil have been limited. Here, we performed field culture experiment by burying nylon bags filled with MPs paddy had treated different fertilizers over 30 years explore changes VFGs plastisphere. Our results show amplified ARG VFG caused fertilization 1.5 1.4 times, respectively. And it also 2.7-fold increase risk horizontal gene transfer. Meanwhile, tended promote deterministic process community assembly HBPs, an times. Network analysis found significant correlation between ARGs, VFGs, bacteria Correlation highlight important role mobile genetic elements (MGEs) communities shaping abundance findings provide insights into health associated due derived from fertilizers.

ABSTRACT Unraveling how agricultural management practices affect soil biota network complexity and stability these changes relate to processes functions is critical for the development of sustainable agriculture. However, our understanding knowledge still remains unclear. Here, we explored effects intensity on complexity, stability, multifunctionality, as well relationships among factors. Four typical land use types representing a gradient disturbance were selected in calcareous red soils southwest China. The four with increasing included pasture, sugarcane farmland, rice paddy fields, maize cropland. cohesion, topological features (e.g., average degree, clustering coefficient, path length, diameter, graph density, modularity), variation degree used evaluate strength interactions between species, respectively. results showed that intensive increased species competition but decreased stability.

Viral Communities Suppress the Earthworm Gut Antibiotic Resistome by Lysing Bacteria on a National Scale

Environmental Science & Technology, Год журнала: 2024, Номер 58(31), С. 13961 - 13972

Опубликована: Июль 22, 2024

Earthworms are critical in regulating soil processes and act as filters for antibiotic resistance genes (ARGs). Yet, the geographic patterns main drivers of earthworm gut ARGs remain largely unknown. We collected 52 samples from arable forest ecosystems along a 3000 km transect across China, analyzing diversity abundance using shotgun metagenomics. Earthworm guts harbored lower compared to soil, resulting stronger distance-decay rate gut. Greater deterministic assembly were found than soil. The had frequency co-occurrence between mobile genetic elements (MGEs) systems. Viral was higher negatively correlated with bacterial diversity. Bacteria such

Antibiotics and Pesticides Enhancing the Transfer of Resistomes among Soil-Bayberry-Fruit Fly Food Chain in the Orchard Ecosystem

Environmental Science & Technology, Год журнала: 2024, Номер unknown

Опубликована: Окт. 4, 2024

While substantial amounts of antibiotics and pesticides are applied to maintain orchard yields, their influence on the dissemination risk antibiotic resisitome in food chain remains poorly understood. In this study, we characterized bacterial fungal communities differentiated both resistance genes (ARGs) virulence factor (VFGs) soil, Chinese bayberry (matured fallen), fruit fly gut, collected from five geographic locations. Our results showed that guts soils exhibit a higher abundance ARGs VFGs compared with fruits. We identified 112 shared 75 VFGs, aminoglycoside adherence being among most abundant. The co-occurrence network revealed some microbes, such as
