Twenty-two non-repetitive carbapenem-resistant Acinetobacter baumannii isolates were obtained from Intensive Care Unit patients. All of the isolates carried bla(OXA-23), bla(OXA-66), a novel cephalosporinase-encoding gene (bla(ADC-25)) and a class 1 integron with an aacC1-orfP-orfQ-aadA1a cassette array and had identical enterobacterial repetitive intergenic consensus (ERIC) profiles. ISAba1 was found upstream of bla(OXA-23), but was not associated with bla(OXA-66) or bla(ADC-25).
