Introduction: An ICU-outbreak caused by a novel Acinetobacter baumannii clone is described. %26lt;br%26gt;Methods: An active search of carriers and environmental reservoirs was carried out. Carbapenemases genes were studied using multiplex-PCR and genotypic analysis by rep-PCR, PFGE and MIST. %26lt;br%26gt;Results: A total 26 infected patients and 10 carriers were identified. A. baumannii was recovered from infusion pumps, walls, floor and washbasins. Phenotypic/genotypic analysis showed clonal expansion of a unique clone ST-187 producer of type OXA-24 and OXA-51 carbapenemases. %26lt;br%26gt;Discussion: This is the first outbreak caused by ST-187 (ECI/GCI) multiresistant A. baumannii.
