Background Chaohu Lake (CL) is one of the most polluted areas in China due to its high content antibiotics. However, distribution and influencing factors antibiotic resistance genes (ARGs) this lake are still controversial. Methods To solve problem, we used metagenomic sequencing investigate in-fluencing ARGs CL. Results Our findings revealed existence nine kinds ARGs, including 45 specific genes. The abundant types were multidrug, bacitracin, polymyxin, macrolide lincosamide streptogramin, aminoglycoside. Multiple microorganisms undeniable ARG reservoirs, although they not dominant species microbiota. results also showed that both microbiota physiochemical played important roles shaping distributions Specifically, levels PO4-P (0.5927) total phosphorus (0.4971) had a greater impact than nitrogen (0.0515), NO 3- N (0.0352), NO2-N (−0.1975), NH3-N (−0.0952). Conclusions These provide valuable insights into lakes.

Antibiotic resistance genes (ARGs) have been extensively observed in bacterial DNA, and more recently, phage particles from various water sources food items. The pivotal role played by ARG transmission the proliferation of antibiotic emergence new resistant strains calls for a thorough understanding underlying mechanisms. aim this study was to assess suitability prototypical p-crAssphage, proposed indicator human fecal contamination, recently isolated crAssBcn phages, both belonging Crassvirales group, as potential indicators ARGs. These crAss-like phages were evaluated alongside specific ARGs (bla

Arsenic contamination in sludge and sediment has emerged as a pressing environmental issue with far-reaching implications. This review delves into the multifaceted problem of arsenic contamination, focusing on its complex interactions microbial resistance genes (MRGs). It explores key role microorganisms biogeochemical cycling arsenic, including processes such reduction, oxidation, methylation, volatilization. describes how resist through that encode proteins efflux pumps, enzymatic detoxification, intracellular sequestration. Arsenic, naturally occurring element, can enter various natural anthropogenic pathways, leading to detrimental effects quality. Understanding mobilization, transformation, their ability toxicity MRGs is essential for effective mitigation remediation strategies. discusses sources distribution sediment, intricate mechanisms resistance, potential implications management human health. also examines current research trends identifies areas requiring further investigation. By unraveling interplay between microorganisms, MRGs, this aims contribute deeper understanding guide future protection efforts.

Bacteriophages are known as players in the transmission of antimicrobial resistance genes (ARGs) by horizontal gene transfer. In this study, we characterized bacteriophage community and associated ARGs to estimate potential for phages spread aquatic ecosystems analyzing intra- extracellular DNA isolated from two wastewater treatment plants (WWTPs) shotgun metagenomics. We compared phage resistome with bacterial investigated effect final disinfection on its resistome. Phage was mainly composed

Domestic wastewater is a significant reservoir of antibiotic resistance genes, which pose environmental and public health risks. We aimed to define an resistome signature, represented by core i.e., shared ≥ 90% the metagenomes each three conceptual compartments - (influent, sludge, effluent), freshwater, agricultural soil. The definition signatures would support proposal framework for monitoring treatment efficacy assessing impact treated discharge into environment, such as freshwater Metagenomic data from 163 samples originating (n = 81), 58), soils 24) across different regions (29 countries, 5 continents), were analysed regarding diversity, based on annotation against database that merged CARD ResFinder databases. relative abundance total genes (corresponding ratio between reads number) was not statistically raw wastewater, being significantly higher than in or soils. latter had lowest genes. Genes conferring aminoglycosides, beta-lactams, tetracyclines among most abundant environments, while multidrug equally distributed all environments. signature included 27 detected at least resistomes, frequent soil resistomes. Among these responsible 8), macrolide-lincosamide-streptogramin B 7), aminoglycosides 4), beta-lactams 3), 2), sulphonamides polypeptides 1). This comprehensive assessment provides valuable insights dynamics urban systems their potential ecological implications diverse settings. Furthermore, guidance implementation One Health approaches.
