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

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.

Fish-related antibiotic resistance genes (ARGs) have attracted attention for their potentially harmful effects on food safety and human health through the chain transfer. However, potential factors affecting these ARGs not been fully explored. In this study, bacterial communities in fish gut, mucosal skin, gill filaments were comprehensively evaluated four different mariculture systems formed by hybrid grouper (Epinephelus fuscoguttatus♀ × E. lanceolatus♂), Gracilaria bailinae, Litopenaeus vannamei using combinations. The results showed that 9 detected gut skin 6 filaments. detection rate of aphA1 was highest, abundance 1.91 10-3 - 6.30 10-2 copies per 16 S rRNA gene. Transposase gene (tnpA-04) all samples with 3.57 3.59 gene, strongly correlated multiple (e.g., aphA1, tet(34), mphA-02). Proteobacteria, Deinococcus-Thermus, Firmicutes, Bacteroidetes dominant phyla systems, accounting 65.1%-96.2% total community. Notably, high relative Stenotrophomonas, a pathogen, elevated 20.5% monoculture system. addition, variation partitioning analysis (VPA) difference between main driving factor distribution differences groupers. This study provides new comprehensive understanding characterization fish-related contamination facilitates assessment risks pathogen taxa to health.
