In the recent years, Salmonella enterica subspecies. Enterica serovar enteritidis is a major cause of gastroenteritis and food poisoning in the worldwide.  Different genus of salmonella is increasingly being resistant to common antibiotics. The aim of this study was to determine the frequency and the antibiotic resistance patterns of Salmonella enterica isolated from medical health centers in Tehran. Methods: In this descriptive cross- sectional study from April to December 2008, 1950 fecal specimens from children with diarrhea were cultivated to identify Salmonella enteritidis. We used Clinical and Laboratory Standard Institute (CLSI) protocol to determine resistance patern of the isolates to 16 different antibiotics. Results: In this study, out of 26 isolates 14(54%) were S. enteritidis, 2(8%) S. para B, 6(23%) S. para C, 3(11%) S. arizonea and 1(4%) S. para A. all of them were sensitive to ceftazidime, cephalexin, cefotaxime, ceftiraxone, ciprofloxacin, imipenem, meropenem, gentamicin and colistin sulfate. All of the isolates were resistant to nitrofurantoin whereas 71.4% of them were resistant to nalidixic acid. Conclusions: The most prevalent isolated salmonella was S.enteritidis. According to high sensivity of these isolates to cephalosporin and flourqouinolon family, they can used as infective treatment for salmonellosis infections.
