Miao S, Zhang Y, Men C, Mao Y, Zuo J. A combined evaluation of the characteristics and antibiotic resistance induction potential of antibiotic wastewater during the treatment process. J Environ Sci (China) 2024; 138:626-636. [PMID: 38135426 DOI: 10.1016/j.jes.2023.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 04/04/2023] [Accepted: 04/04/2023] [Indexed: 12/24/2023]
Abstract
Antibiotic wastewater contains a variety of pollutant stressors that can induce and promote antibiotic resistance (AR) when released into the environment. Although these substances are mostly in concentrations lower than those known to induce AR individually, it is possible that antibiotic wastewater discharge might still promote the AR transmission risk via additive or synergistic effects. However, the comprehensive effect of antibiotic wastewater on AR development has rarely been evaluated, and its treatment efficiency remains unknown. Here, samples were collected from different stages of a cephalosporin production wastewater treatment plant, and the potential AR induction effect of their chemical mixtures was explored through the exposure of the antibiotic-sensitive Escherichia coli K12 strain. Incubation with raw cephalosporin production wastewater significantly promoted mutation rates (3.6 × 103-9.3 × 103-fold) and minimum inhibition concentrations (6.0-6.7-fold) of E. coli against ampicillin and chloramphenicol. This may be attributed to the inhibition effect and oxidative stress of cephalosporin wastewater on E. coli. The AR induction effect of cephalosporin wastewater decreased after the coagulation sedimentation treatment and was completely removed after the full treatment process. A Pearson correlation analysis revealed that the reduction in the AR induction effect had a strong positive correlation with the removal of organics and biological toxicity. This indicates that the antibiotic wastewater treatment had a collaborative processing effect of conventional pollutants, toxicity, and the AR induction effect. This study illustrates the potential AR transmission risk of antibiotic wastewater and highlights the need for its adequate treatment.

Epidemiological Description and Detection of Antimicrobial Resistance in Various Aquatic Sites in Marseille, France. Microbiol Spectr 2023; 11:e0142622. [PMID: 36976002 PMCID: PMC10101087 DOI: 10.1128/spectrum.01426-22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 12/22/2022] [Indexed: 03/29/2023] Open
Abstract
Antibiotic resistance is a worldwide public health concern and has been associated with reports of elevated mortality. According to the One Health concept, antibiotic resistance genes are transferrable to organisms, and organisms are shared among humans, animals, and the environment. Consequently, aquatic environments are a possible reservoir of bacteria harboring antibiotic resistance genes. In our study, we screened water and wastewater samples for antibiotic resistance genes by culturing samples on different types of agar media. Then, we performed real-time PCR to detect the presence of genes conferring resistance to beta lactams and colistin, followed by standard PCR and gene sequencing for verification. We mainly isolated Enterobacteriaceae from all samples. In water samples, 36 Gram-negative bacterial strains were isolated and identified. We found three extended-spectrum β-lactamase (ESBL)-producing bacteria-Escherichia coli and Enterobacter cloacae strains-harboring the CTX-M and TEM groups. In wastewater samples, we isolated 114 Gram-negative bacterial strains, mainly E. coli, Klebsiella pneumoniae, Citrobacter freundii and Proteus mirabilis strains. Forty-two bacterial strains were ESBL-producing bacteria, and they harbored at least one gene belonging to the CTX-M, SHV, and TEM groups. We also detected carbapenem-resistant genes, including NDM, KPC, and OXA-48, in four isolates of E. coli. This short epidemiological study allowed us to identify new antibiotic resistance genes present in bacterial strains isolated from water in Marseille. This type of surveillance shows the importance of tracking bacterial resistance in aquatic environments. IMPORTANCE Antibiotic-resistant bacteria are involved in serious infections in humans. The dissemination of these bacteria in water, which is in close contact with human activities, is a serious problem, especially under the concept of One Health. This study was done to survey and localize the circulation of bacterial strains, along with their antibiotic resistance genes, in the aquatic environment in Marseille, France. The importance of this study is to monitor the frequency of these circulating bacteria by creating and surveying water treatments.

Abstract
Introduction In the twenty-first century, antibiotic resistance is becoming one of the major global public health threats. Several complex factors are associated with the emergence and spread of antibiotic resistance. Emerging evidences are indicating that drugs used for chronic illness conditions might have a contribution for antibiotic resistance either through drug–drug interactions or metabolism of the drugs by gut microbiota. Objective The aim of this study was to compare the bacteria profile and resistance patterns of gut bacteria isolated from participants using psychotropic drugs and apparently healthy controls. Methods Socio-demographic data were collected from patients using psychotropic medications and apparently healthy persons. Clinical data were collected from patient records. Stool samples were collected from 107 patients using psychotropic medications and 107 apparently healthy controls. Gut bacterial flora were isolated and identified using oxidase, indole, and BD BBL crystal Enteric/Non-fermenter identification system. Antibiotic susceptibility test was done using the disk diffusion method, and Mast disks were used to identify extended-spectrum betalactamase (ESBL) and/or AmpC-producing isolates. Results A total of 245 bacterial isolates were isolated and identified. From these, 124 (50.6%) bacteria were isolated from patients using Psychotropic medications. There was no bacteria profile difference between the two groups. Escherichia coli was the prevalent [100 (80.6%) and 102 (84.3%)] bacteria isolated from patients using psychotropic medications and apparently healthy controls, respectively. Escherichia coli isolated from patients using psychotropic medications showed significantly higher resistance against amoxicillin-clavulanic acid, cephalosporin (2nd, 3rd, 4th generations), meropenem, ciprofloxacin and tetracycline. The odds of isolating ESBL-producing Enterobacteriaceae [(OR=2.3, 95% C.I: (1.4–4.0)] and MDR [OR=5.4, 95% C.I: (1.5–29.8)] were higher on patients using psychotropic medications. Conclusion The observed antibiotic resistance pattern of bacteria isolated from guts of patients using psychotropic medications was very high. The magnitude of antibiotic resistance is more pronounced among E. coli isolates.

Abstract
Wastewater treatment plants (WWTPs) are considered to be a reservoir and a source of bacterial resistance. Worryingly, the presence of carbapenem-resistant Gram-negative bacilli (CRGNB) in WWTPs has recently been reported, but there are still many research gaps regarding its emergence and impact. The distribution of CRGNB in the different stages of a WWTP in Colombia and the relationship between the physicochemical factors involved with their presence are described in this paper. Additionally, given the impact on public health, the CRGNB detected were compared with isolates previously found in hospital patients. Residual water samples were taken from five different stages of a WWTP between January and July 2017. A total of 390 GNB were isolated, and a significant frequency of CRGNB harboring blaKPC-2 (38.2%, n = 149/390) was detected, of which 57% were Enterobacteriaceae, 41.6% Aeromonadaceae, and 1.3% Pseudomonadaceae. The Enterobacteriaceae were more frequent in the raw effluent compared to the Aeromonadaceae, which in turn were more prevalent in the recycled activated sludge and final effluent. Environmental variables such as pH, oxygen, chemical oxygen demand, and temperature were significantly correlated with the quantification of carbapenem-resistant Enterobacteriaceae (CRE) at specific points in the WWTP. Interestingly, isolated K. pneumoniae harboring blaKPC-2 from the WWTPs were diverse and did not relate genetically to the hospital strains with which they were compared. In conclusion, these results confirm the worrying scenario of the dissemination and persistence of emerging contaminants such as CRGNB harboring blaKPC-2, and reinforce the need to establish strategies aimed at containing this problem using multifocal interventions.

Abstract
Increasing beta-lactam resistance has led to the exploration of different places, such as wastewater treatment plants (WWTPs) which have been considered to be reservoirs and sources of bacterial resistance. This work aims to determine the presence of beta-lactamase-producing-Enterobacteriaceae in different points of a WWTP in Colombia. Six samplings were carried out in 2017 in the raw influent, aeration tanks, recycled sludge and final effluent of a WWTP. The beta-lactamase-producing-Enterobacteriaceae were detected and identified using phenotypic and molecular methods. Of the 353 isolates included, 28.3% corresponded to enterobacteria. The most frequent microorganisms were Escherichia coli (83%), Citrobacter freundii (11%) and Enterobacter cloacae complex (4%). The 97% of enterobacteriaceae had at least one beta-lactamase, and the most prevalent were the blaTEM (43.8%) and blaCTX-M-1group (35.8%) which were detected specially in recycled sludge and final effluent sample points. High percentage of multidrug resistance (to beta-lactams and non-beta-lactam antibiotics) was detected in E. coli (63.2%). Additionally, the typing by PFGE and MLST showed high genotypic diversity and the presence of the successful ST131 clone, globally spread. This work highlights the strong role of E. coli as a vector for the dissemination of resistance and the beta-lactamases in aquatic environments.

Degradation of antibiotics and antibiotic resistance genes in fermentation residues by ionizing radiation: A new insight into a sustainable management of antibiotic fermentative residuals.

Abstract
Antibiotic fermentative residues are categorized into hazardous wastes in China due to the existence of antibiotic resistance genes (ARGs) and residual antibiotics How to treat and manage these wastes is a new challenge. This paper investigated the treatment of erythromycin thiocyanate fermentation (EryTcF) residues using ionizing radiation technology for removing ARGs and antibiotics from the fermentation residues. The results showed that as exposed the EryTcF residues to gamma radiation, the abundance of four macrolide resistance genes (ereA, ermB, mefA and mpfB) decreased 1.0-1.3 log with 90-95% removal, and around 56% of erythromycin was removed at absorbed dose of 30 kGy and room temperature (19-22 °C). Direct action of γ-ray radiation contributed to 42-53% of ARGs removal and indirect action (radicals' reaction) was mainly responsible for erythromycin removal (84%). The positive correlation between total ARGs and Shannon index was observed. The potential ARGs-linked hosts were assigned to genera Aeromonas and Enterobacteriaceae and their abundance decreased by 36-43% at 30 kGy. Radiation has not obvious influence on the nutrient components of residues, such as protein content, suggesting that the radiation treated fermentative residues can be used as fertilizer, which is favorable for the development of recycling economy in antibiotic pharmaceutical factory. The results could provide a new insight into a sustainable management of antibiotic fermentative residuals.
