title: [Molecular characterization of the strain causing a shigellosis outbreak in a Madrid school].
abstract: BACKGROUND
  The aim of this study is to describe a Shigella sonnei outbreak in a school.
  
  
  METHODS
  An epidemiological inquiry was performed. Stool samples from 5 patients were cultured. Molecular typing of the isolates was carried out by PFGE, MLST and plasmid analysis.
  
  
  RESULTS
  The attack rate was 14.3% (67 students). Shigella sonnei was isolated from all 5 patients. The four strains available for typing were indistinguishable.
  
  
  CONCLUSIONS
  These results suggest a common identity of the outbreak strain.
