We have studied the antimicrobial properties of 6-bromoeugenol and eugenol by three strains: Pseudomonas aeruginosa (S1), Escherichia coli (S2) and Staphylococcus aureus (S3). We have determined the minimum inhibitory concentration (MIC) for a range of concentrations using the disc diffusion method. We note that all samples present an antimicrobial activity toward the tested bacterial strains at different concentrations (1, 0.5 and 0.25 mg/ml). The 6-bromoeugenol gives modest activity with (S1) and (S3). Eugenol reacts positively with the Pseudomonas aeruginosa (S1) at all concentrations and with the Escherichia coli (S2) at 0.5 mg/ml. We remark that the Pseudomonas aeruginosa (S1) is the more sensitive strain than Escherichia coli (S2) and Staphylococcus aureus (S3). We have estimated the activity coefficient which has confirmed the antimicrobial activity of the different samples. So, 6-bromoeugenol has shown his efficiency as antimicrobial agent.
