ABSTRACT AbaR resistance islands in Acinetobacter baumannii isolates from South Korea were investigated. AbaR4-type resistance islands, including bla OXA-23 -containing Tn 2006 , interrupted the comM gene in A. baumannii ST75 isolates. However, Tn 2006 was not identified within AbaR resistance islands of ST138 isolates, although the bla OXA-23 gene was detected in them. The similar structures of resistance islands suggest that most carbapenem-resistant A. baumannii isolates in South Korea have originated from the same ancestor with a globally disseminated clone, GC II.
