The present study aimed to determine the in vitro synergistic effect of Origanum vulgare and penicillin on the resistance of Enterococcus Faecalis ATCC 29212. 10 ml was obtained. Of essential oil, by means of the process denominated distillation by drag of steam of water. The strain was obtained from the microbiology section of the National University of Trujillo. For the determination of the synergistic effect by the technique of Kirby and Bauer; Sterile filter paper discs were prepared, which were submerged within each concentration of oregano essential oil: 75%, 100%, mixed equally with penicillin. Subsequently they were placed in Petri dishes containing cultures of microorganisms; With the result that the groups of disks imbued with 100% oregano essential oil and the essential oil group of oregano + penicillin had a higher average. Concentrations of the 75%, 100%, oregano essential oil, mixed in equal parts with penicillin, were used for the minimum inhibitory concentration and for the Minimum Inhibitory Concentration, 4 test tubes were prepared for each concentration of 75% and 100%. 6 groups of 10 petri dishes each were formed; Group I (75% essential oils), group II (100% essential oil), group III (75% essential oil + penicillin), group IV (100% essential oil + penicillin), group V , Group VI (penicillin alone). Observing growth only in group V. Statistical analysis was used ANOVA where the average diameter of inhibition halos and halos of colony forming units were determined according to research groups. By means of the Duncan test that allows to evidence the existence of 4 groups statistically different from each other. Concluding that the oil essences of Origanum vulgare possesses antimicrobial effect in vitro on strains of Enterococcus faecalis Atcc29212 in addition to synergism with penicillin.
