Abstract

The newly identified plasmid-borne colistin resistance gene mcr-1 was found in a Kluyvera ascorbata isolate from hospital sewage in China. mcr-1 was carried by a 57-kb self-transmissible IncI2 plasmid. Unlike in a previous report, mcr-1 was not associated with ISApl1 and was inserted into a gene encoding a putative membrane protein by an unknown mechanism. This study highlights that mcr-1 has spread to multiple bacterial species.

摘要

在中国医院污水分离出的一株抗坏血酸克吕沃尔氏菌中发现了新鉴定的质粒介导的黏菌素耐药基因mcr-1。mcr-1由一个57 kb的可自我传递的IncI2质粒携带。与之前的报道不同,mcr-1与ISApl1无关,并且通过未知机制插入到一个编码假定膜蛋白的基因中。这项研究强调了mcr-1已经传播到多种细菌物种。
