Analysis of the molecular characteristics of a blaKPC-2-harbouring untypeable plasmid in Serratia marcescens

Serratia marcescens has attracted increasing attention worldwide as a neglected opportunistic pathogen of public health concern, especially due to its antimicrobial resistance features, which usually cause nosocomial infections in immunocompromised or critically ill patients. In our study, four carbapenem-resistant Serratia marcescens (CRSM) clinical isolates were characterized in our hospital from February 2018 to May 2018. The conjugation...
