The population structure of 71 carbapenem-resistantAcinetobacter baumannii clinical isolates from several hospitals in Brazil was investigated by ApaI pulsed-field gel electrophoresis,bla OXA-51 -like subtyping, and multilocus sequence typing (Institute Pasteur scheme). In addition to the predominance of strains carryingbla OXA-23 , we detected the presence ofbla OXA-72 andbla OXA-231 . We observed a predominance of clonal complex 1 (CC1), CC15, and CC79 and representative strains of the worldwide-disseminated international clone I.
