The elevated levels of antibiotic resistance genes (ARGs) in livestock manure represent a significant threat to both the environment and human health. Composting has been recognized as an effective strategy mitigate abundance ARGs manure. However, notable rebounds have observed during this process. This study explored changes underlying influencing factors composting carnivore (chicken pig) herbivore (sheep cow) manures, along with mushroom residues. findings revealed that total relative increased by 6.96 10.94 folds chicken pig composts, respectively, whereas it decreased remarkable 91.72% 98.37% sheep cow composts. Nitrogen content emerged primary physicochemical governing Conversely, carbon played pivotal role determining Furthermore, presence dominant hosts, such Corynebacterium, Bacillus, Clostridium, emerging bacteria like Thermobifida, Saccharomonospora, Actinomadura, contributed significantly enrichment ARGs, including tetG, tetO, tetX, sul2, coexistence these mobile genetic elements plethora host bacteria, coupled their high abundance, renders them particularly high-risk ARGs. On other hand, decrease composts can be attributed decline population specifically Atopostipes, Psychrobacter, Corynebacterium. Collectively, results provide crucial insights into management risks offer essential theoretical support for enhancing safe utilization organic fertilizer agriculture.

The impact of microcystin on antibiotic resistance genes and microbial communities in Yangtze River sediments

Environmental Technology, Год журнала: 2025, Номер unknown, С. 1 - 14

Опубликована: Март 8, 2025

The escalating of water pollution associated with microcystins (MCs) and antibiotic resistance genes (ARGs) poses a significant environmental challenge. As one China's most crucial systems, the Yangtze River's ecological health is not only vital for regional ecosystems but also carries global significance. While concentration MCs detected in River sediments moderate, impact exogenous on ARGs microbial communities within these remains poorly understood. This study examines 18 sediment samples collected from six regions along upper, middle, lower reaches River. By introducing MCs, we analyzed responses sulfonamide gene (sul1), tetracycline (tetA), integron (intI1), community composition. results indicate that MC inputs significantly affect abundance sediments, sul1, tetA, intI1 exhibiting general increasing trend. However, structure was substantially affected by differences exerting greater influence composition than input. Proteobacteria, Bacteroidetes, Acidobacteria, Chloroflexi were dominant phyla sediments. introduction may increase risk ARG dissemination. These findings enhance our understanding how dissemination structures ecosystem.
