title: Emergence of Acinetobacter baumannii international clone II in Brazil: reflection of a global expansion.
abstract: The aim of this study was to investigate the occurrence of carbapenem-resistant Acinetobacter baumannii international clones (IC) in Curitiba, Brazil, using multilocus sequence typing and trilocus PCR-based typing schemes. IC2 was the first emerging clone. This IC was detected in an isolate from 2003 of a PFGE type spread in at least two hospitals since 1999. Subsequently, IC2 waned while IC1 and clonal complex 15/104 prevailed. This is the first description of IC2 in Brazil and Latin America.
