We report here the nucleotide sequence of a novel blaKPC-2-harboring incompatibility group N (IncN) plasmid, pECN580, from a multidrug-resistant Escherichia coli sequence type 131 (ST131) isolate recovered from Beijing, China. pECN580 harbors β-lactam resistance genes blaKPC-2, blaCTX-M-3, and blaTEM-1; aminoglycoside acetyltransferase gene aac(6')-Ib-cr; quinolone resistance gene qnrS1; rifampin resistance gene arr-3; and trimethoprim resistance gene dfrA14. The emergence of a blaKPC-2-harboring multidrug-resistant plasmid in an epidemic E. coli ST131 clone poses a significant potential threat in community and hospital settings.
我们在此报告从中国北京分离出的一株多重耐药性大肠杆菌序列型131(ST131)中,一个携带新型blaKPC - 2的不相容群N(IncN)质粒pECN580的核苷酸序列。pECN580含有β - 内酰胺抗性基因blaKPC - 2、blaCTX - M - 3和blaTEM - 1;氨基糖苷乙酰转移酶基因aac(6') - Ib - cr;喹诺酮抗性基因qnrS1;利福平抗性基因arr - 3;以及甲氧苄啶抗性基因dfrA14。在流行的大肠杆菌ST131克隆中出现携带blaKPC - 2的多重耐药性质粒,在社区和医院环境中构成了重大潜在威胁。
