Investigating the occurrence of antibiotic-resistance genes (ARGs) in sedimentary archives provides opportunities for reconstructing distribution and dissemination historical (i.e., non-anthropogenic origin) ARGs. Although ARGs freshwater environments have attracted great attention, variations diversity abundance over centuries to millennia remain largely unknown. In this study, we investigated vertical change patterns bacterial communities, mobile genetic elements (MGEs) found sediments Lake Chenghai spanning past 600 years. Within resistome preserved sediments, 177 subtypes were with aminoglycosides multidrug resistance being most abundant. The ARG upper sediment layers (equivalent post-antibiotic era since 1940s) was lower than those during pre-antibiotic era, whereas higher possibly because human-induced lake eutrophication recent decades facilitated spread proliferation drug-resistant bacteria. Statistical analysis suggested that MGEs community structure significantly correlated ARGs, suggesting may be transferred between different bacteria by MGEs. Our results provide new perspectives on natural history are essential understanding temporal dynamics

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.

The spread of antibiotic resistance genes (ARGs) and subsequent soil-borne disease outbreaks are major threats to soil health sustainable crop production. However, the relationship between occurrences diseases transmission ARGs remains unclear. Here, ARGs, mobile genetic elements microbial communities from co-located suppressive conducive banana orchards were deciphered using metagenomics metatranscriptomics approaches. In total, 23 ARG types, with 399 subtypes, detected a approach, whereas 452 discovered method. Furthermore, analysis revealed that total abundance levels greater in rhizospheres (0.45 ARGs/16S rRNA on average) compared bulk (0.32 soils. Interestingly, abundances disease-conducive (8.85 soils than (1.45 Mobile showed same trends as ARGs. Network binning analyses indicated Mycobacterium, Streptomyces, Blastomonas main potential hosts Bacillus was significantly negatively correlated Fusarium (P < 0.05, r = -0.84) (i.e., Blastomonas). By comparing metagenomic metatranscriptomic analyses，this study demonstrated may be more sensitive indicating activities soil. Our findings enable accurate assessment risk data provide new perspective for recognizing health, which appear associated spread, beneficial microbe enrichment mitigate wilt transmission.

Abstract Antibiotic Resistance Genes (ARGs) are widespread in freshwater environments and represent a concealed threat to public health aquatic eco-system safety. To date, only limited number of studies have investigated the historical distribution ARGs their hosts through analysis sedimentary archives. This research gap constrains our comprehensive mechanisms underlying natural bacterial resistance formation during pre-antibiotic era (prior 1940s) development human-induced post-antibiotic (since 1940s). In this study, we examined vertical patterns associated within core from eutrophic lake, employing shotgun sequencing methodology. The findings revealed marked increase ARG diversity era, predominant types identified included those conferring multidrug, bacitracin, macrolide–lincosamide–streptogramin, beta-lactam, tetracycline, fluoroquinolone, glycopeptide aminoglycoside, collectively accounting for 78.3%–85.6% total abundance. A 127 subtypes were samples, 48 shared across sediment resistome profile with two them, bac bcr A, occurring era. Further, 137 metagenome-assembled genomes (83 species belonging 12 phyla) as hosts, mainly phyla Proteobacteria, Nitrospirota, Chloroflexota, Bacteroidota, Actinobacteriota, Cyanobacteria, Firmicutes. Significant correlation was found between concentrations organic matter heavy metals, suggesting common source contamination. Aside fact that eutrophication is forcing factor acting parallel releases water systems, both being indicators increased urbanization catchment, may significantly activity, thereby facilitating spread antibiotic-resistant bacteria environment. study reveals onset antibiotic use by human societies potential impact ecosystem.
