  The aim of this study was to investigate the antimicrobial activity of Prosopis farcta L. and Datura stramonium L. extracts on Salmonella thyphimurium isolated from poultry in Zabol. The P. farcta and D. stramonium were collected from Collection of medicinal plants, Institute of Agricultural Research at University of Zabol. Strains of Salmonella thyphimurium were isolated from poultry droppings. Antibiotic resistance pattern was determined by Kirby Bauer method. Finally, the minimum inhibitory concentration (MIC) and minimum bactericide concentration (MBC) were determined by microdilution method. The results of this study showed that the lowest inhibitory concentration of Datura extract against Salmonella typhimurium was 3.1 ppm; While the minimum inhibitory concentration for Prosopis extract was 6.5 ppm. Also, the minimum bactericidal concentration of Datura extract was 6.25 and Prosopis extract was 12.5. The results of this study showed that Datura extract was more effective in inhibiting Salmonella bacteria than Prosopis extract. Evaluation of Pearson correlation coefficient between total phenol content, total flavonoids and MIC, and MBC showed an inverse relationship between these parameters. So that the Datura extract, which contained higher total phenol, and total flavonoid, had lower MIC and MBC and therefore was more effective in inhibiting bacteria. The results of our experiments showed that Datura and Prosopis extracts have good antimicrobial effects and can be used to treat infections caused by Salmonella typhimurium in poultry.

  Due to the increasing need to gain knowledge about the inhibitory effects of plants, in this study, the antimicrobial effects of Carum copticum, Rosa damascene, Anethum graveolens and Cuminum cyminum essential oils on some bacteria and yeast were investigated. The essential oils were extracted using a Clevenger apparatus and their compounds were determined by gas chromatography equipped with a mass spectrometer. Also, the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of the essential oils were determined and their antimicrobial properties were compared by well-diffusion method. MIC results of Bacillus cereus and Staphylococcus aureus showed that Cuminum cyminum essential oil with 50 µg/ml had the lowest bactericidal effect. The essential oils of Carum copticum, Anethum graveolens and Rosa damascene had the highest bactericidal effect with 0.78 μg/ml on the studied bacteria. In the case of Escherichia coli, the highest antimicrobial effect was shown by Carum copticum essential oil at 6.25 μg/ml. Rosa damascene essential oil, with a concentration of 3.12 μg/ml, had the highest antifungal properties on Candida albicans. In the case of Saccharomyces cerevisiae, the most antifungal effect was provided by Rosa damascene and Cuminum cyminum essential oils with 0.78 μg/ml. The antibacterial effect of Carum copticum essential oil was higher than the other three essential oils. In the case of yeasts, Rosa damascene and Cuminum cyminum essential oils had the most antifungal effect. According to the results, Carum copticum essential oil in controlling bacteria and Rosa damascene essential oil in controlling studied yeasts are recommended. Manuscript profile
