The antibacterial activities of six organic solvent extracts of Salicornia iranica against Salmonella typhimurium

The overuse of antibiotics in poultry industries may lead to a rise in antibiotic-resistance, in humans and animals. Natural antibiotics degrade in living tissues, and therefore, they do not induce antibiotic-resistance. In this study, the antibacterial activity of six organic solvent extracts of S. iranica were investigated against S. typhimurium. The results indicate a significant antibacterial activity of S. iranica extracts against S.typhimurium (p 0.01). The maximum and minimum inhibitory activity of organic solvent extracts compared with 0.5 mg/ml of tetracycline were detected for butanol and acetyl acetate (50 mg/ml) treatments, respectively.
