OBJECTIVE: To identify homogenous clones of S. flexneri 2a, using gene distribution polymorphism of Shigella enterotoxin 1 (set 1) and Shigella enterotoxin 2 (set 2) in a Shigellosis outbreak caused by S. flexneri 2a.
METHODS: In addition to field epidemiological investigation, 43 strains of S. flexneri 2a were determined by polymerase chain reaction (PCR).
RESULTS: The 43 strains (1 from food, 1 from a carrier, 41 from patients) were divided into 3 clones (set1 +/set2 + for 39 strains, set1 -/set2 + for 1, set1 +/set2 - for 3 strains).
CONCLUSION: This outbreak was caused by S. flexneri 2a. The route of transmission was contaminated-food borne. Some sporadic cases were noticed during the outbreak. The method used in this study was satisfactory to the identification of S. flexneri 2a.
