Background and Aim: Shigella infection is one of the prevalent causes of diarrhea disease in most developing countries in children under 10 years old. Conventional microbiological examination to identify Shigella species are time-consuming and requires a lot of work and cost. The object of the present research was to isolate and identify of serotypes of Shigella, Shigella sonnei from patients with bacillary dysentery and to detect their one major virulence genes ipaH by using PCR.

Materials and Methods: 3000 stool sample from children with diarrhea admitted in two famous hospitals in1391 in summer & autumn in Tehran were used in this study. The identification of isolated was done by serogrouping and biochemical test & the prevalence of ipaH gene determined by PCR method using specific pairs of primers. Antimicrobial susceptibility of isolates was performed according to the CLSI guidelines.

Results: All Shigella spp isolates in this study harbored the ipaH gene. Out of 160 shigella isolates, 50 isolates determined as S. sonnei with serogrouping and biochemical test. 90% of isolates were resistant to Tetracycline, Cotrimoxazole, Streptomycin and Minocycline.

Conclusions: We conclude that ipaH PCR procedure is more reliable, sensitive, easier, reproducible and specific which is significantly faster than current conventional detection assays such as serologic test. Althuogh in this study we report that among Shigella .spp cause diarrhea infection most of them are S .sonnei resistant antibiotic.
