Background: Multidrug resistance in Salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. Methods: Salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to PCR and identified as Salmonella enteritidis. For detection and identification of Salmonella enteritidis isolates, sdfI gene-specific primers were used. Results: We found that ۱۰۰% of isolates were resistant to ampicillin, ۹۰% were resistant to cephalothin and streptomycin, ۷۰% were resistant to cefotaxime, and ۶۰% were resistant to kanamycin and gentamicin Conclusion: Salmonella enteritidis isolates had antimicrobial resistance to mentioned antibiotics.
