Background: The infections caused by Salmonella enterica serovar enteritidis (Salmonella enteritidis) have been increasing in developed and developing countries. The aim of this study was to investigate the genetic relationship between the strains of Salmonella enteritidis.Methods: In a descriptive study from 2008 to 2010, clinical Salmonella enteritidis strains were collected from the patients referred to different hospitals in Tehran. The strains identified by biochemical and serological methods. Genetic relationships between the isolates were investigated using pulsed field gel electrophoresis (PFGE) method.Findings: Of 40 Salmonella enteritidis isolated strains, two PFGE profiles were obtained which among them, 32 (80%) and 8 (20%) of isolates belonged to cluster A and cluster B, respectively. Based on PFGE patterns, 28 (70%) strains exhibited nine bands and were belonged to cluster A.Conclusion: The result of this study indicated that isolated Salmonella enteritidis strains belonged to the closed clones.
