The widespread selective pressure of antibiotics in the environment has led to propagation antibiotic resistance genes (ARGs). However, mechanisms by which microbes balance population growth with enrichment ARGs remain poorly understood. To address this, we employed microcosm cultivation at different (i.e., Oxytetracycline, OTC) stresses across concentrations from environmental clinical. Paired shot-gun metagenomics analysis and quantification bacterial growth, trait-based assessment soil microbiota was applied reveal association between key ARG subtypes, representative taxa, functional-gene features that drive ARGs. Our results illuminate resistome variation is closely associated growth. A non-monotonic change abundance richness observed over a concentration gradient none 10 mg/l. Soil exposed intermediate OTC 0.1 0.5 mg/l) showed greater increases total Community compositionally, i.e., Pseudomonadaceae considered boost increase It chromosomally carried kinds multidrug such as mexAB-oprM mexCD-oprJ could mediate intrinsic OTC. Streptomycetaceae shown better adaptive ability than other clinical concentrations. it contributed less represents stress-tolerant lifestyle grows slowly carries fewer In terms community genetic features, aggregated traits further indicates enhancement resource acquisition yield driving abundance. Moreover, optimizations energy production conversion, alongside streamlining bypass metabolic pathways, sub-inhibitory conditions. this study suggest competitive lifestyles are selected under stress nutrient scarcity. They possess substrate utilization capacity carry more ARGs, due they were faster growing leading This expanded application assessments understanding ecology propagation. And finding illustrated changes accompanied switching microbiome, theoretically supports control approach based on principle species exclusion.

Anaerobic digestion (AD) converts animal and agricultural waste into biogas, offering significant benefits for management renewable energy production. It enhances security, reduces dependence on imports, mitigates greenhouse gas emissions. Despite its potential, AD faces challenges that require improved policies, investments, training. Technological advancements, such as nanotechnology, can further increase biogas production, while byproducts like biofertilizer contribute to farm profitability. However, pathogens in (AW), Escherichia coli Salmonella, pose public health risks through contamination of water, food, surfaces. Efficient livestock is essential reduce environmental impacts, the proper pricing natural resources, including land, landfills, crucial sustainability. The include generation, reduction, pathogen elimination, conversion organic high-quality fertilizer, which supports productivity. remain, smallscale technology, impurities, temperature sensitivity, limited applicability urban areas. To improve economic feasibility, fermentation process be conducted controlled environments using tanks. This study explores strategies effective biomass resource management, focusing optimizing production by-product utilization sustainable development.

Objective: We set out to evaluate the persistence of sulfachloropyridazine, oxytetracycline, and enrofloxacin in broiler chicken litter following therapeutic oral treatment its association with isolation Escherichia coli resistant these antimicrobials. Methods: Forty chickens were raised under controlled conditions divided into three experimental groups, each treated a different antimicrobial, addition an untreated/control group. Litter samples collected post treatment, analyzed by UPLC-MS/MS, processed for E. coli. The antimicrobial susceptibility was assessed using Kirby–Bauer disk diffusion method. Results: Chemical analysis detected concentrations antimicrobials throughout reaching maxima 42,910.14 μg kg−1, 92,712 9567 kg−1 oxytetracycline plus 4-epi-oxytetracycline, ciprofloxacin, respectively. It estimated that would persist 61, 244, 514 days, A very strong observed between presence residues resistance (p-value < 0.0001, Cramer’s coefficient 0.47), independence level residue concentration 0.5262). Conclusions: contributes selection bacteria, regardless persistent concentrations. These findings highlight need stricter regulations on poultry management, including thresholds monitoring, minimize environmental public health risks. Proper is essential ensure sustainable safe re-use agricultural systems.
