Abstract

A multidrug-resistant plasmid encoding TEM-1, SHV-12, and a variant of IMP-2 metallo-beta-lactamase, designated IMP-8, was identified from a clinical isolate of Klebsiella pneumoniae. There are four nucleotide differences between bla(IMP-2) and bla(IMP-8), resulting in two amino acid differences. bla(IMP-8) was also found to be carried by an integron-borne gene cassette similar to the bla(IMP-2) cassette.

摘要

从肺炎克雷伯菌的临床分离株中鉴定出一种携带TEM-1、SHV-12和IMP-2金属β-内酰胺酶变体(命名为IMP-8)的多重耐药质粒。bla(IMP-2)和bla(IMP-8)之间存在四个核苷酸差异,导致两个氨基酸差异。还发现bla(IMP-8)由一个与bla(IMP-2)基因盒相似的整合子携带的基因盒携带。
