Abstract

Abstract : Enterobacter aerogenes has recently emerged as an important hospital pathogen. In this study, we showed the emergence of E. aerogenes isolates carrying the bla KPC gene in patients colonized by carbapenem‐resistant Klebsiella pneumoniae strains. Two multiresistant E. aerogenes isolates were recovered from bronchial aspirates of two patients hospitalized in the Intensive Care Unit at the "Santa Maria della Scaletta" Hospital, Imola. The antimicrobial susceptibility test showed the high resistance to carbapenems and double‐disk synergy test confirmed the phenotype of KPC and AmpC production. Other investigation revealed that ESBL and bla KPC genes were carried on the conjugative pKpQIL plasmid. This is a relevant report in Italy that describes a nosocomial infection due to the production of KPC beta‐lactamases by an E. aerogenes isolate in patients previously colonized by K. pneumoniae carbapenem‐resistant. In conclusion, it's necessary a continuous monitoring of multidrug‐resistant strains for the detection of any KPC‐producing bacteria that could expand the circulation of carbapenem‐resistant pathogens.
