Persistence and potential risks of tetracyclines and their transformation products in two typical different animal manure composting treatments.

Abstract
Abundant residues of tetracyclines in animal manures and manure-derived organic fertilizers can pose a substantial risk to environments. However, our knowledge on the residual levels and potential risk of tetracyclines and their transformation products (TPs) in manure and manure-derived organic fertilizers produced by different composting treatments is still limited. Herein, the occurrence and distribution of four veterinary tetracyclines (tetracycline, oxytetracycline, chlortetracycline, and doxycycline) and ten of their TPs were investigated in paired samples of fresh manure and manure-derived organic fertilizers. Tetracyclines and TPs were frequently detected in manure and manure-derived organic fertilizer samples in ranging from 130 to 118,137 μg·kg-1 and 54.6 to 104,891 μg·kg-1, respectively. Notably, the TPs concentrations of tetracycline and chlortetracycline were comparable to those of the parent compounds, with 4-epimers being always dominant and retained antibacterial potency. Based on paired-sampling strategy, the removal efficiency of tetracyclines and TPs in thermophilic composting was higher than that in manure storage. Toxicological data in the soil environment and the data derived from equilibrium partitioning method, indicated that tetracyclines and some TPs like 4-epitetracycline, 4-epichlortetracycline and isochlortetracycline could pose median to high ecological risk to terrestrial organisms. Total concentrations of TPs in manure-derived organic fertilizers were significantly correlated with the absolute abundance of tet(X) family genes, which provide evidence to evaluate the effects of TPs on the levels of antibiotic resistance in the environment. Among them, the 4-epitetracycline could pose ecological risk and retain antibacterial potency. Our findings emphasize the importance of monitoring and controlling the prevalence of tetracyclines and their TPs in livestock-related environments.

Decoding the enigma: unveiling the molecular transmission of avian-associated tet(X4)-positive E. coli in Sichuan Province, China. Poult Sci 2023; 102:103142. [PMID: 37879166 PMCID: PMC10618799 DOI: 10.1016/j.psj.2023.103142] [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: 06/07/2023] [Revised: 09/18/2023] [Accepted: 09/18/2023] [Indexed: 10/27/2023] Open
Abstract
Tigecycline is considered one of the "last resort antibiotics" for treating complex infections caused by multidrug-resistant (MDR) bacteria, especially for combating clinical resistant strains that produce carbapenemases. However, the tet(X4) gene, which carried by different plasmids can mediate high levels of bacterial resistance to tigecycline, was first reported in 2019. Here, we report the emergence of the plasmid-mediated tet(X4) in avian environment of Sichuan Province. A total of 21 tet(X4)-positive Escherichia coli (E. coli) strains were isolated and identified from avian samples in selected regions, with an isolation rate of 1.6% (21/1,286), and all of them were MDR strains. Multilocus Sequence Typing (MLST) method was used to classify the 21 tet(X4)-positive E. coli into the ST206, ST761, ST155, ST1638, ST542, and ST767 types, which also belong to the 3 phylogenetic subgroups A, B1, and C. Tet(X4) is located on mobile plasmids that can be efficiently and stably propagated. The results of fitness cost experiments showed that tet(X4)-positive plasmids may incur some fitness cost to host bacteria, but different tet(X4)-positive plasmids bring about differential fitness costs. Whole-genome sequencing further confirmed the tet(X4) gene can be located on IncX1-type plasmids and the core genetic structures are ISVsa3-rdmc-tet(X4) or rdmc-tet(X4)-ISVsa3, the former is a 7 copies tandem repeat structure. In this study, we isolated and identified tet(X4)-positive E. coli from the avian origin in Sichuan, analyzed the mobility of the tet(X4) by conjugational transfer and S1-PFGE, and evaluated the biological characteristics of the tet(X4)-positive plasmid using the results of conjugational frequency, plasmid stability, and fitness costs. Finally, combined with the third-generation whole-genome sequencing analysis, the molecular transmission characteristics of the tet(X4) were preliminarily clarified, providing a scientific basis for guiding veterinary clinical use in this area, as well as risk assessment and prevention of the transfer and spread of tigecycline resistant strains or genes.

Abstract
Anaerobic digestion has been proved as one promising strategy to simultaneously achieve resource recovery and environmental pollution control for biosolid treatment, and adding exogenous materials is a potential alternative to promote the above process. This study investigated response mechanisms of anaerobic digestion of waste activated sludge (WAS) to particle sizes of zeolite. Results showed that the methane production reached 186.75 ± 7.62 mL/g volatile suspended solids (VSS) with zeolite of the particle size of 0.2-0.5 mm and the additive dosage of 0.1 g/g VSS, which increased by 22% compared to that in control. Mechanism study revealed that zeolite could improve hydrolysis, acidification, and methanogenesis stages. Rapid consumption rates of soluble polysaccharides and proteins were observed, correspondingly, the accumulation of SCFAs were enhanced, and the compositions of SCFAs were optimized. Moreover, the activities of F420 increased by 28% with zeolite, and the syntrophic metabolism between bacteria and methanogens were promoted.

Hyper-thermophilic anaerobic pretreatment enhances the removal of transferable oxazolidinone and phenicol cross-resistance gene optrA in enterococci. WASTE MANAGEMENT (NEW YORK, N.Y.) 2023; 167:92-102. [PMID: 37245400 DOI: 10.1016/j.wasman.2023.05.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 05/08/2023] [Accepted: 05/18/2023] [Indexed: 05/30/2023]
Abstract
The extensive use of florfenicol in poultry industry results in the emergence of optrA gene, which also confers resistance to clinically important antibiotic linezolid. This study investigated the occurrence, genetic environments, and removal of optrA in enterococci in mesophilic (37 °C) and thermophilic (55 °C) anaerobic digestion systems, and a hyper-thermophilic (70 °C) anaerobic pretreatment system for chicken waste. A total of 331 enterococci were isolated and analyzed for antibiotic resistance against linezolid and florfenicol. The optrA gene was frequently detected in enterococci from chicken waste (42.7%) and effluents from mesophilic (72%) and thermophilic (56.8%) reactors, but rarely detected in the hyper-thermophilic (5.8%) effluent. Whole-genome sequencing revealed that optrA-carrying Enterococcus faecalis sequence type (ST) 368 and ST631 were the dominant clones in chicken waste, and they remained dominant in mesophilic and thermophilic effluents, respectively. The plasmid-borne IS1216E-fexA-optrA-erm(A)-IS1216E was the core genetic element for optrA in ST368, whereas chromosomal Tn554-fexA-optrA was the key one in ST631. IS1216E might play a key role in horizontal transfer of optrA due to its presence in different clones. Hyper-thermophilic pretreatment removed enterococci with plasmid-borne IS1216E-fexA-optrA-erm(A)-IS1216E. A hyper-thermophilic pretreatment is recommended for chicken waste to mitigate dissemination of optrA from animal waste to the environment.
