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.
