We report the presence of mcr-1 in Escherichia coli and carbapenem-resistant Cronobacter sakazakii from the same diseased chicken. The mcr-1 gene linked with ISApl1 was located on two different IncI2 plasmids, including one multidrug plasmid in E. coli, whereas fosA3-bla was on an IncB/O plasmid in C. sakazakii The development of the fosA3-bla resistance region was mediated by IS26 The colocation of mcr-1 or bla with other resistance genes will accelerate the dissemination of the two genes.
我们报告了在同一只患病鸡的大肠杆菌和耐碳青霉烯类阪崎肠杆菌中存在mcr-1。与ISApl1相连的mcr-1基因位于两个不同的IncI2质粒上,其中一个是大肠杆菌中的多药质粒,而fosA3-bla位于阪崎肠杆菌的一个IncB/O质粒上。fosA3-bla耐药区域的形成是由IS26介导的。mcr-1或bla与其他耐药基因的共定位将加速这两个基因的传播。
