摘要整合子是一个新的细菌耐药基因水平传播元件，近年来学者们对其介导的病原菌耐药机制进行了大量研究。本文在阐述整合子介导细菌多重耐药机制的基础上，总结其在肠杆菌科细菌、鲍曼不动杆菌和铜绿假单胞菌等细菌中的检出情况及新发现整合子基因盒类型，并展望未来研究方向。（中华检验医学杂志，2017，40：7-10）

abstractsIntegron was a novel bacterial resistance gene horizontal transmission element.In recent years, many researchers made a lot of research on the resistance mechanism of pathogen.In this paper, the detection and the novel discovery of the integron gene cassette were summarized , including Enterobacteria, Acinetobacter baumanii, Pseudomonas aeruginosa and other bacteria , on the basis of the multidrug resistance mechanism mediated by integron.The prospect the research was descixbed and more attention should be paid to the prevention and control of multidrug resistant bacteria.
