Three patients admitted to a Greek hospital were infected with Serratia marcescens isolates that exhibited reduced susceptibility to carbapenems and harbored Klebsiella pneumoniae carbapenemase (KPC) enzymes. In two of these cases, the patients were initially infected by carbapenem-susceptible S. marcescens isolates. Molecular typing and plasmid analysis suggested that all three patients had clonally indistinguishable isolates of S. marcescens that acquired a plasmid-mediated bla(KPC-2) gene during the hospitalization.
三名入住希腊医院的患者感染了对碳青霉烯类药物敏感性降低的粘质沙雷氏菌分离株,这些分离株携带产碳青霉烯酶肺炎克雷伯菌(KPC)。在这两例患者中,最初感染的是对碳青霉烯类药物敏感的粘质沙雷氏菌分离株。分子分型和质粒分析表明,所有这三例患者的粘质沙雷氏菌分离株均具有克隆不可区分的特征,这些分离株在住院期间获得了一种质粒介导的bla(KPC-2)基因。
