Background and objectives: Salmonella is recognized as a major food-borne pathogen in humans
worldwide. Antimicrobial drug resistance is increasing among Salmonella spp. and causes significant
therapeutic problems in the treatment of diseases caused by this organism. The aim of this study was to
determine the aminoglycoside resistance pattern of Salmonella spp. isolated from clinical cases in Tehran.
Material and Methods: Salmonella spp. strains were isolated from several hospitals in Tehran during 2007- 2008. The strains were identified by standard biochemical methods and serology. The susceptibility of the isolates to aminoglycoside antibiotics was determined according to Clinical and Laboratory Standards Institute (CLSI) guidelines.
Results: The results showed that 44.1% of the strains were resistant to streptomycin, 22.8% to kanamycin, 19.1% to neomycin, 0.7% to tobramycin and 0% to gentamycin.
Conclusion: We found a diverse pattern of aminoglycosides resistance among Salmonellaspp., the resistance to streptomycin and kanamycin was considerable, whereas to tobramycin and gentamycin was very low. While aminoglycoside resistance varied by Salmonellaserogroups, continuous monitoring of resistance patterns and the use of antibiotic agents according to individual serogroup is recommended.
