ABSTRACT
Objective To identify homogenous clones of S.flexneri 2a, using gene distribution polymorphism of Shigella enterotoxinl and Shigella enterotoxin2 in a shigellosis outbreak by S.flexneri 2a. Methods 93 strains of S.flexneri 2a isolated from different areas, at different time were detected by Shigella enterotoxin1 and Shigella enterotoxin2 gene polymerase chain reaction to identify genetic type of S.flexneri 2a. Results The 93 strains of S.flexneri 2a were divided into 4 clones ShET1(-)/ShET2(+)for 12 strains,ShET1(+)/ShET2(-)for 14 strains,ShET1(+)/ShET2(-)for 59 strains, ShET1(-)/ShET2(-)for 8 strains. Conclusions It is believed that Shigella enterotoxin1 and Shigella enterotoxin2 gene PCR analysis is a simple method for the primary screening of S.flexneri 2a.
