title: [New clone of ST-187 Acinetobacter baumannii responsible for an outbreak in an intensive care unit].
abstract: BACKGROUND
  An ICU-outbreak caused by a novel Acinetobacter baumannii clone is described.
  
  
  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 MLST.
  
  
  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.
  
  
  CONCLUSIONS
  This is the first outbreak caused by ST-187 (ECI/GCI) multiresistant A.baumannii.
