Abstract
Introduction: The aim of this study was to evaluate the effect of nano oxide on Salmonella typhimurium isolated from poultry in
Zabol.
Methods: Zinc nano oxide was purchased. The S. typhimurium was isolated from poultry in Zabol and the minimum inhibitory
concentration (MIC) and minimum bactericidal concentration (MBC) were determined by the microdilution method.
Results: The results of this study showed that the MIC against S. typhimurium was 93 μg/mL, and 3 strains were inhibited in
this concentration. In addition, the maximum inhibitory concentration was 3000 μg/mL, and one strain was inhibited in this
concentration as well.
Conclusion: The results of this study demonstrated good antimicrobial effects of zinc oxide nanoparticles on S. typhimurium,
which can be used to treat infections caused by S. typhimurium.
