An strain isolated from the feces of swine at a pork slaughterhouse in Henan province China was found to possess two colistin-resistance genes, and , plus 16 additional resistance genes. Genes and were identified on IncHI2 and IncX1 type plasmids, respectively. Transconjugants (containing , &) were obtained that were 64- and 512-fold higher than the minimum inhibitory concentration of colistin on the recipient bacteria ( C600), respectively. The IncX1 plasmid containing displayed a very specific structure compared with previous . Variable and stable regions were similar across different plasmids, multiple insertion sequences and transposases.
从中国河南省一家猪肉屠宰场的猪粪便中分离到一株 菌株，该菌株携带两种黏菌素耐药基因 和 ，以及另外 16 种耐药基因。基因 和 分别位于 IncHI2 和 IncX1 型质粒上。获得了含有 、和 的转染子（），它们对受体菌（C600）的最小抑菌浓度（MIC）的耐药性分别提高了 64 倍和 512 倍。与之前的 相比，携带 的 IncX1 质粒表现出非常特殊的结构。不同质粒之间的可变区和稳定区相似，存在多个插入序列和转座酶。
