Dissemination of carbapenemase-producing Enterobacteriaceae and Pseudomonas aeruginosa in Romania.

Fifteen carbapenemase-producing Enterobacteriaceae isolates and 12 carbapenemase-producing Pseudomonas aeruginosa isolates were recovered from patients hospitalized between August 2011 and March 2013 at the Hospital of Infectious Disease, Cluj-Napoca, Romania. One KPC-, nine NDM-1-, four OXA-48-, and one VIM-4-producing Enterobacteriaceae isolates along with 11 VIM-2-producing and one IMP-13-producing P. aeruginosa isolates were recovered from clinical samples. All carbapenemase genes were located on self-conjugative plasmids and were associated with other resistance determinants, including extended-spectrum β-lactamases and RmtC methylases.
