Abstract:

Background: The enteric infection resulting from Salmonella are still of special significance in many parts of the world
especially in developing countries. Different types of Salmonella have increasingly become resistant to the common antibiotics
used in therapy. The aim of this study were determination of antibiotic resistance patterns of Salmonella isolated from patients
referred to central laboratory of Tabriz.
Material & Methods: In this study 1147 stool samples were collected from patients referred to central laboratory of Tabriz
since April 2013 till April 2014. Specimens were cultured in Maconkey agar, Selenit F and HectonEntric Agar. Non lactose
fermentation colonies in Maconkey agar or like Salmonella colonies in HectonEntric Agar picked from the culture plates
and were subjected to further analysis. Salmonella strains were biochemically identified by differential media. All Salmonella
strains were serotyped using BharAfshan Kit. Antibiotic susceptibility was determined by Kirby-Bauer disk diffusion method
on Muller Hinton Agar.
Results: 1147 stool specimens yielded 4 Salmonella cases (%0.3) were isolated of which 3 of them were Salmonella paratyphi C
and one was Salmonella paratyphi B. All of isolates were resistance to co-trimoxazol, Nalidixic Acid and sensitive to Gentamycin,
ciprofloxacin, chloramphenicol, Amoxicilin and Ceftaiaxion.
Conclusion: The prevalent Salmonella strain isolated in this study belonged to Salmonella paratyphi. All samples were sensitive
to commonly used antibiotics. This is date give an insight to consider in control programs.
