Official Report of Food Borne Disease Outbreaks Due to Shigella in Iran in 2012

Shigella species are the major cause of foodborne outbreaks in world and in developing countries. The antibiotic resistance patten of such microorganisms for the treat foodborne diseases is vital, The aim of this study was to isolate the most common serotype of Shigella responsible of food bore disease, and determination of their antibiotic rseistance paterns. This was a descriptive study. In total 305 stool samples of patients that cosumed contaminated foods and had diarrhea, fever and cramp were collected.The samples were for culture, sero-grouping,and antibiogram. Among 305 examined samples collected from different provinces 6.9% were idntified as Shigella spp.The Shigella Sonnei was the most common type(71.5%), and Yazd provinces with (52.3%) was the most abundent, while 39% of isolate were collected in autumn. The results of antibiotic suseptibility showed that 100% of serotypes were sensitive to ciprofloxacin,and All cerotypes were resistant to trimethoprim-sulfamethoxazole. Shigella species are one of the main causes of foodborne related outbreaks. The knowledge of bacterial agent of foodborne diseases and determination of antimicrobial resistance pattern are helpful to reduce the rate of foodborne outbreaks, the cost of treatment.The prevention control of outbreaks is also very important.
