Abstract

We report the first draft genome sequence of a Salmonella strain with plasmid-mediated resistance to colistin encoded by mcr-1 gene in Vietnam. Salmonella enterica subsp. enterica serovar Rissen was isolated from a Vietnamese pig slaughterhouse in 2013. We can confirm that mcr-1 gene is identical to the first reported mcr-1 gene of the Escherichia coli strain SHP45, isolated in 2015 from a Chinese pig. The plasmid containing this gene in the strain 19CS0416 was highly related (96.86% identity) to the plasmid (pHNSHP45) contained in this Chinese strain. Moreover, this plasmid was determined to be 100% identical to a plasmid (p13P477T-7) belonging to an Escherichia coli (13P477T) found in Hong Kong during the same year in pigs. Our results will aid in understanding the dissemination of mcr-1 gene in East Asia, dating back to as early as 2013.

多重耐药肠沙门氏菌亚种基因组序列草图。2013年越南分离的大肠杆菌血清型Rissen菌株19CS0416已显示出mcr-1质粒介导的对粘菌素的耐药性。

我们报道了越南一株由mcr-1基因编码的质粒介导的粘菌素耐药沙门氏菌的第一个基因组序列草图。肠道沙门氏菌亚种2013年在越南一家生猪屠宰场分离出血清瑞森肠杆菌。我们可以确认mcr-1基因与2015年从中国猪中分离出的大肠杆菌SHP45株的首次报道的mcr-1基因相同。菌株19CS0416中含有该基因的质粒与该菌株的质粒pHNSHP45高度相关(同源性为96.86%)。此外，该质粒与同年在香港猪身上发现的大肠杆菌(13P477T)的质粒(p13P477T-7) 100%相同。我们的研究结果将有助于了解mcr-1基因在东亚的传播，最早可追溯到2013年。
