“…As demonstrated in Fig. 4, reductions of 0.38 and 0.46 log (reported as absolute abundance) were identified for sul2 and ermB during post-ozonation, respectively, comparable to the removal of sul1and sul2 (up to 0.5 log) reported by Hu et al [18]. In addition, the relative abundance of multiple ARGs also decreased [76].…”

“…Studies of full-scale DWTPs have demonstrated that limited alteration of the ARB ratios was achieved by pre-ozone treatment [80] and the absolute abundance of ARGs would either slightly decrease or increase depending on gene types [18]. Interestingly, Hu et al [23] noted that pre-ozone treatment could enhance the resistance removal effects of the subsequent coagulation and filtration process (analogous to the enhanced organic removal mentioned above).…”

“…Interestingly, Hu et al [23] noted that pre-ozone treatment could enhance the resistance removal effects of the subsequent coagulation and filtration process (analogous to the enhanced organic removal mentioned above). Compared to preozonation, the post-ozonation process was more efficient in abatement of ARB and ARGs [18,76,80], probably because of the higher ozone doses and the presence of fewer ozone-depleting substances in the influent of post-ozonation. As demonstrated in Fig.…”

“…Numerous researchers have conducted lab-scale trials to discern the antibiotic resistance attenuation in individual processing units [16,17], however, they could neither simulate the random variations of autochthonous microbial communities in actual treatment systems, nor elucidate the seasonal and regional distribution of antibiotic resistance [18]. Hence, the results of field trials should be underscored and expanded clarification is still required.…”

Antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) have been widely identified as emerging pollutants in various aquatic compartments. Concerns have been raised that the antibiotic resistance determinants may occur in treated drinking water and wastewater, weakening the therapeutic efficacy of antibiotics and so posing threat to public health. Most often, laboratory trials are conducted to assess the removal efficiency of ARB and ARGs in individual treatment processes (e.g., disinfection). However, the random variations of microbial distribution and chemical compositions in real-world environments cannot be entirely simulated, presumably leading to false-positive results as a consequence. It is therefore useful to provide a summary of recent advancements regarding the antibiotic resistance attenuation during full-scale water/wastewater treatments, which has not been adequately evaluated so far. In this review, the prevalence, proliferation and transmission of ARB and ARGs in urban water cycle, coupled with corresponding detection methods are presented as a short overview. The fate of ARB and ARGs in the sequential drinking water and wastewater processing units is critically summarized, the aim of which is to provide guidance for improving the current water treatment facilities to further reduce the antibiotic resistance in finished water.

“…ARGs can enter the environment through the agricultural use of sludge from livestock farms and fermentation residues, or the discharge of sewage treatment plant effluents from municipal wastewater [8,9]. Due to the rapid spread and transfer of resistance genes in the environment [10][11][12][13][14], ARGs were detected in several surface water and drinking water treatment plants worldwide [11,[15][16][17][18]. Conventional treatment strategies are designed to eliminate the major organic contaminants and hygiene-relevant microorganisms from drinking water [19]; however, they are mostly insufficient to eliminate residual ARGs [20].…”

Performance of Layer-by-Layer-Modified Multibore® Ultrafiltration Capillary Membranes for Salt Retention and Removal of Antibiotic Resistance Genes

et al. 2020

Polyether sulfone Multibore® ultrafiltration membranes were modified using polyelectrolyte multilayers via the layer-by-layer (LbL) technique in order to increase their rejection capabilities towards salts and antibiotic resistance genes. The modified capillary membranes were characterized to exhibit a molecular weight cut-off (at 90% rejection) of 384 Da. The zeta-potential at pH 7 was −40 mV. Laboratory tests using single-fiber modified membrane modules were performed to evaluate the removal of antibiotic resistance genes; the LbL-coated membranes were able to completely retain DNA fragments from 90 to 1500 nt in length. Furthermore, the pure water permeability and the retention of single inorganic salts, MgSO4, CaCl2 and NaCl, were measured using a mini-plant testing unit. The modified membranes had a retention of 80% toward MgSO4 and CaCl2 salts, and 23% in case of NaCl. The modified membranes were also found to be stable against mechanical backwashing (up to 80 LMH) and chemical regeneration (in acidic conditions and basic/oxidizing conditions).

The emergence and rapid spread of antimicrobial resistance is of global public health concern. The gut microbiota harboring diverse commensal and opportunistic bacteria that can acquire resistance via horizontal and vertical gene transfers is considered an important reservoir and sink of antibiotic resistance genes (ARGs). In this review, we describe the reservoirs of gut ARGs and their dynamics in both animals and humans, use the One Health perspective to track the transmission of ARG‐containing bacteria between humans, animals, and the environment, and assess the impact of antimicrobial resistance on human health and socioeconomic development. The gut resistome can evolve in an environment subject to various selective pressures, including antibiotic administration and environmental and lifestyle factors (e.g., diet, age, gender, and living conditions), and interventions through probiotics. Strategies to reduce the abundance of clinically relevant antibiotic‐resistant bacteria and their resistance determinants in various environmental niches are needed to ensure the mitigation of acquired antibiotic resistance. With the help of effective measures taken at the national, local, personal, and intestinal management, it will also result in preventing or minimizing the spread of infectious diseases. This review aims to improve our understanding of the correlations between intestinal microbiota and antimicrobial resistance and provide a basis for the development of management strategies to mitigate the antimicrobial resistance crisis.
