Molecular epidemiology of carbapenem-resistant Acinetobacter baumannii in a newly established Greek hospital.

One hundred and sixty-four Acinetobacter baumannii isolates, collected from patients hospitalized in a newly established hospital in Northern Greece during the 8-year period (2001-2008) of its operation, were tested for the presence of Ambler class A and D carbapenemases and typed by random amplified polymorphic DNA and pulsed-field gel electrophoresis. Isolates were clustered into five distinct clones. The majority of isolates were carrying the bla(OXA-58) gene, while a new clone emerged in 2008.
