Abstract

Herein, we describe a case report of carbapenem-resistant and isolates that were identified from the same patient at a Tertiary University Hospital Centre in Portugal. Antimicrobial susceptibility and the molecular characterization of resistance and virulence determinants were performed. PCR screening identified the presence of the resistance genes , and in both isolates. The KPC-3 isolate belonged to the ST-14 high risk clone and accumulated an uncommon resistance and virulence profile additional to a horizontal dissemination capacity. In conclusion, the molecular screening led to the first identification of the KPC-3 producer in Portugal with a full antimicrobial resistance profile including tigecycline and colistin.

摘要

在此,我们描述了在葡萄牙一家三级大学医院中心从同一患者身上鉴定出的耐碳青霉烯类菌株的病例报告。进行了抗菌药物敏感性以及耐药性和毒力决定因素的分子特征分析。PCR筛查确定在两种分离株中均存在耐药基因、和。KPC-3分离株属于ST-14高风险克隆,除具有水平传播能力外,还积累了罕见的耐药和毒力谱。总之,分子筛查首次在葡萄牙鉴定出具有包括替加环素和黏菌素在内的完整抗菌药物耐药谱的KPC-3产生菌。
