Detection and horizontal transfer of antibiotic resistance genes during wastewater treatment processes
-
摘要: 抗生素的滥用使得近年来环境中抗生素频繁检出，同时污水处理厂接纳不同来源的污水后也促进了抗性基因的水平转移.现阶段抗性基因和水平转移的定性、定量检测手段多样化，尤其是水平转移的机制也备受关注.本文介绍了抗生素抗性基因和水平转移的检测方法以及抗性基因水平转移的研究进展，展望了今后的发展方向，以期为抑制抗性基因的扩散提供技术参考.Abstract: Antibiotics are frequently detected in environment these days due to their abuse. Their horizontal genes transfer (HGT) in wastewater treatment plants is intensified because wastewater from different source is collected here (There are various). Qualitative and quantitative detection methods of antibiotic resistance genes(ARGs) and horizontal transfer at present, and the pathways of HGT have particularly received great attention. This review introduces the detection method of ARGs and HGT, summarizes the research progress on horizontal transfer of ARGs, then proposes the direction of future work aimed to provide technical reference for the elimination of dissemination of ARGs.
