Introduction: The aim of this study is to describe a Shigella sonnei outbreak in a school.
Method: 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.
Conclusion: These results suggest a common identity of the outbreak strain.
