The interaction between antibiotics and antibiotic resistance genes (ARGs) in freshwater ecosystems has become a critical environmental concern. This study investigates seasonal variations of sulfonamide tetracycline their relationship with ARGs three urban reservoirs Nanjing, China: Pingshan Forest Park, Shanhu Lake Wetland Zhaoqiao Reservoir. Sampling was conducted May September 2023 to assess water quality, concentrations, ARG abundance. A total 30 samples were analyzed regard physicochemical parameters, heavy metals, antibiotics. quantitative PCR assay used measure the abundance relative 16S rRNA gene. Sulfonamide concentrations ranged from 120 ng/L, while tetracyclines 50–160 ng/L. Notably, sulfamethazine decreased significantly two (Shanhu Zhaoqiao, p < 0.05), other showed minimal variation, indicating persistent contamination agricultural runoff wastewater discharge. lower than September, being cumulatively genes. Strong correlations (r > 0.7) observed parameters like dissolved oxygen pH. High levels areas without nearby hospitals or pharmaceutical companies, implicating agriculture as major pollution source. By analyzing across eutrophic China, we highlight drivers proliferation propose targeted mitigation strategies.

ESKAPE bacteria represent a group of opportunistic bacterial pathogens that display widespread antimicrobial resistance, including resistance to the last-line antibiotics, thereby posing significant clinical implication globally. Anthropogenic activities, such as wastewater from hospitals, livestock farms, crop fields, and treatment plants, contribute dissemination antimicrobial-resistant into environment. Surface water sources, river waters, act critical points discharge for wastewater, pollutants, antibiotic-resistant (ARB), genes (ARG). These environmental factors, along with others, facilitate survival ARBs, well promote exchange ARGs. Therefore, it is crucial comprehend current landscape concerning prevalence persistence resistant bacteria, particularly those belonging group. This review aims provide comprehensive overview characterization in surface sources.

Abstract The conventional practice of using sewage treatment plant (STP) derived sludge as a fertilizer poses significant negative impacts on agroecosystems. Since has diverse contaminants, including heavy metals (HMs), antibiotics (ABs) and antibiotic resistance genes (ARGs), its application in the agricultural fields contaminates food hence causes human health risks via chain. transfer ABs ARGs from to soil then plants can influence development (AR) endophytes, leads variations their characteristics. In pot experiment, vegetable carrot ( Daucus carota ) spinach Spinacia oleracea were amended with samples three (STPs) varying capacities both above below-ground parts analysed for presence specific (amoxicillin, azithromycin, chloramphenicol, ciprofloxacin, tetracycline), blaCTX-M, blaGES, blaNDM, ermF, qnrS, Sul1 ), mobile genetic elements (MGEs) intl1 , IS26 ). Among characterized culturable endophytic bacteria (EB), 22 exhibited various (highest against ampicillin, chloramphenicol) lead, nickel, chromium). Most importantly, seven multiple antibiotic-resistant (MAREB) all tested (HMs). Additionally, MAREB positive biofilm production, notable proportion (72.72%) these endophytes displayed mobility, strong auto-aggregation ranging 16.67 92.61%. formation dynamics among Gaussian distribution pattern, increasing higher concentrations. Notably, five demonstrated survival at clarithromycin concentrations up 150 µg ml −1 . study revealed (µg kg (copies vegetables, 2.87 314.88 1 × 10 5 3.2 respectively. advantageous features support growth under different stress conditions. Moreover, 51.09% identified EBs reported human-associated pathogens, 9.09% solely pathogens. Transfer factor (TF), translocation (TLF), bioconcentration (BCF) values correlated abundance root shoot compartments vegetables. risk assessment highlighted children are particularly vulnerable prolonged adverse consuming Therefore, this research is imperative understanding co-selection mechanisms, need improvement existing systems contaminants removal, evaluation before fields.
