Background & Aim: The aim of this study was to investigate the antimicrobial activity of two rangeland-medical plants extracts, Prosopis farcta L. and Datura stramonium L., against Staphylococcus aureus isolated from sheep in Zabol city. Experimental: The P. farcta and D. stramonium were collected from the rangelands of Zabol city. Staphylococcus aureus strains were isolated from the nose of sheep in Zabol city. 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. Results: The results of this study showed that the P.farcta extract had a MIC of 25 ppm, and 10 strains of the bacterium were inhibited in this concentration. The lowest inhibitory concentration of D.stramonium extract was 6.25 ppm, and one strain was inhibited in this concentration. On the other hand, the highest inhibitory concentration was 50 ppm and the highest bactericide concentration was 100 ppm. Recommended applications/ industries: The results of this study showed good antimicrobial effects of D. stramonium and P. farcta extracts that can be used to treat Staphylococcus aureus infections.
