Introduction & Objective: Due to emerging of resistance of microorganisms to antibiotics, investigations for novel antimicrobial agents have always been one of the major preoccupations of the medical society. Traditional medicine systems have played an important role during human evolution and development. Today, a number of medical herbs around the world have been studied for their medicinal activities. Amongst the several herbal medicine used as a medicine, Dorema auchri is yet another potent herbal medicine which has not been extensively studied for the medicinal uses in comparison with other herbal medicine. Dorema auchri has a long history of use as a sore and food additive in Yasuj, Iran. However, not much scientific work has been conducted on Dorema auchri antimicrobial activities. The present study aimed to study the antimicrobial properties of Dorema auchri on some pathogen microorganisms. Materials & Methods: In the present study was conducted at Yasuj University of Medical Sciences in 2009. After collection and preparation of hydro alcoholic extract of Dorena auchri, the extract was used to study its activities against human pathogen microorganisms (overall 10 microorganisms). The determination of minimal inhibitory concentration (MIC) and minimum lethal concentration were evaluated for this extract. The antimicrobial potent of Dorema auchri extract was compared with commercial antibiotics. Each experiment was done three times and collected data were analyzed by SPSS using ANOVA and Chi-Square tests. Results: Findings of this study showed that in 10 mg/ml concentration, all bacteria were resistant to Dorema auchri extract. In 20 mg/ml concentration, only Staphylococcus areus and Staphylococcus epidermis showed zone of inhibition (ZOI) 10 mm and 13 mm respectively. In 40 mg/ml concentration, the maximum ZOI was 15 mm in Staphylococcus areus and 80 mg/ml concentration, the maximum ZOI was 20 mm in Staphylococcus areus. The acceptable MIC and MLC were 20 mg/ml and 40 mg/ml in Staphylococcus areus, Staphylococcus epidermis and Streptococcus pneumonia respectively. Conclusion: Our data clearly indicated that the Dorema auchri extract have antibacterial properties against Staphylococcus areus, Staphylococcus epidermis and Streptococcus pneumonia comparable with standard antibiotics.
