Among the 2,105 Enterobacteriaceae tested in a survey done in Portugal, 165 were nonsusceptible to carbapenems, from which 35 (26 Klebsiella pneumoniae, 3 Escherichia coli, 2 Enterobacter aerogenes, and 3 Enterobacter cloacae isolates and 1 Klebsiella oxytoca isolate) were confirmed to be carbapenemase producers by the presence of 30 Tn4401d-blaKPC-3, 4 intI3-blaGES-5, and one intI1-blaVIM-2 gene, alone or in combination with other bla genes. The dissemination of blaKPC-3 gene carried by an IncF plasmid suggests lateral gene transfer as a major mechanism of dissemination.
在葡萄牙进行的一项调查中检测的2105株肠杆菌科细菌中,有165株对碳青霉烯类不敏感,其中35株(26株肺炎克雷伯菌、3株大肠埃希菌、2株产气肠杆菌、3株阴沟肠杆菌分离株和1株产酸克雷伯菌分离株)通过单独或与其他bla基因组合存在30个Tn4401d-blaKPC-3、4个intI3-blaGES-5和1个intI1-blaVIM-2基因而被确认为碳青霉烯酶产生菌。由IncF质粒携带的blaKPC-3基因的传播表明横向基因转移是传播的主要机制。
