[Molecular characterization of the strain causing a shigellosis outbreak in a Madrid school].
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.
