| Abstract: | 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 contaminatedfood borne. Some sporadic cases were noticed during the outbreak. The method used in this study was satisfactory to the identification of S.flexneri 2a. |
