Nowadays, antibacterial effects of medicinal plants are considered as an appropriate alternative of antibiotics. Therefore, the aim of the current study was in vitro determination of antimicrobial effects of caper (Capparis spinosa) against Salmonella typhmurium isolated from poultry. Ethanol extract of caper leaves was extracted using vacuum from the center (rotary) apparatus. Moreover, a total number of 12 S. typhmurium strains were isolated from poultry in Zabol. Minimum inhibitory concentration and minimum bactericidal concentration of different concentrations of plant extract were determined on bacteria using dilution in well method. Sensitivity of bacteria strains to antibiotics were evaluated using Kirby-Bauer disk diffusion standard test. Results of the current study showed that different strains of bacteria are resistant to Penicillin (100 %), Ampicillin (100 %), Tetracycline (16.6 %) and Amikacin (8.3 %). Furthermore, ethanol extracts of caper plant showed significant inhibitory effect on S. typhimurium. Results of the current study indicated that there is possibly of using ethanol extract of caper plant as a useful alternative beside usual antibiotics.
