The flanking genetic structure of qnrA1 in Korean Enterobacter loacae was identical to that of the Chinese Escherichia coli strain, the first qnrA1-carrying strain reported in Asia. Analysis of restriction enzyme sites and Southern blot hybridization results showed that qnrA1 was transferred between E. cloacae and E. coli via Inc HI2 type plasmid.
在韩氏肠杆菌中 qnrA1 的侧翼基因结构与中国大肠杆菌株完全相同,这是亚洲首例报道的携带 qnrA1 的菌株。酶切位点分析和 Southern blot 杂交结果表明,qnrA1 通过 Inc HI2 型质粒在阴沟肠杆菌和大肠杆菌之间转移。
