Clinical isolates of Klebsiella pneumoniae producing NDM-1 carbapenemase from India (n = 22), the United Kingdom (n = 13), and Sweden (n = 4) were subjected to multilocus sequence typing (MLST), automated repetitive sequence-based PCR (rep-PCR), serotyping, virulence gene screening, and plasmid replicon typing. The most frequently detected MLST sequence types (STs) were ST14 (n = 13; all serotype K2), ST11, ST149, ST231, and ST147. The correlation between MLST and automated rep-PCR was excellent. IncA/C was the most frequently detected plasmid replicon type (n = 14). ST14, ST11, and other successful clones may be important for the dissemination of bla(NDM-1).
从印度(n=22)、英国(n=13)和瑞典(n=4)分离到的产 NDM-1 碳青霉烯酶的肺炎克雷伯菌临床分离株进行多位点序列分型(MLST)、自动化重复序列基元 PCR(rep-PCR)、血清分型、毒力基因筛查和质粒复制子分型。最常检测到的 MLST 序列型(ST)是 ST14(n=13;均为 K2 血清型)、ST11、ST149、ST231 和 ST147。MLST 和自动 rep-PCR 之间的相关性极好。IncA/C 是最常检测到的质粒复制子类型(n=14)。ST14、ST11 和其他成功克隆可能对 bla(NDM-1)的传播很重要。
