Abstract
For the charges effect of chemical drugs and limit their use, disposition use of medicinal plants has increased. With the expansion of aquaculture, the occurrence of bacterial disease is inevitable and in this study the effects of antibacterial essential oils of Mentha (Mentha spicata), cloves Hindi (Eugenia caryophyllata) , cuminum cyminum and Rosmarinus officinalis on the bacterium, Vibrio,, parahaehaemolyticus Vibrio harveyi , Vibrio damsela andYersinia ruckeri been studied. Broth dilution method (Broth Micro-dilution) for determining the Minimum Inhibitory Concentration (MIC) used, and then by MIC, Minimum Bactericidal Concentration (MBC) was determined for each extract. In order to compare the effects of essential oils, the diameter of bacterial growth obtained by the disk diffusion method (Disk diffusion) were used. The results showed that Vibrio harveyi bacteria were more resistant than other and clove essential oils has a high power to inhibit bacteria. The lowest MIC and MBC is respectively 2 and 4 mg/ml for Eugenia caryophyllata and Mentha spicata against Vibrio parahaehaemolyticus and the highest MIC and MBC respectively were 8 and 16 mg/ml for Mentha spicata and cuminum cyminum essence against vibrio harveyi. The maximum diameter of bacteria inhibition zone is 12 mm for Eugenia caryophyllata essence against Vibrio Damsla bacteria. Rosmarinus officinalis was the low power of lethal bacteria. . On the basis of investigation, we can say, E. caryophyllata could be used as a source of new antibacterial agent for developing drugs to inhibit some fish pathogenic bacteria.
