is a newly identified plasmid-borne colistin resistance gene, but its mobilization mechanism remains unclear. In this study, was found on an IncFIB plasmid carrying virulence genes , /, and in a isolate. By comparison with closely related plasmids, two recombination sites were identified flanking the genetic element containing and an integrase-encoding gene, suggesting that site-specific recombination mediated by an integrase of an integrative mobile element is a potential mechanism for mobilizing .
是一个新发现的质粒介导的黏菌素抗性基因,但其转移机制仍不清楚。在本研究中,在一株分离菌的携带毒力基因、/和的IncFIB质粒上发现了。通过与密切相关的质粒比较,在包含和一个整合酶编码基因的遗传元件两侧鉴定出两个重组位点,这表明由整合型移动元件的整合酶介导的位点特异性重组是转移的一种潜在机制。
