Objective: To evaluate the in vitro antimicrobial activities of the crude oil of Eucalyptuscamaldulensis Methods: The essential oils of E. camaldulensis harvested from the garden of the Health Center in Sidi Bel Abbes city (North West of Algeria), were screened for their antibacterial activities against two clinical bacteria [Escherichia coli (E. coli), Staphylococcus aureus (S. aureus)] by the agar disc diffusion method and broth dilution susceptibility assay.Results:(E. camaldulensis) leaves. 31 mm and 10-26 mm respectively for E. coli and S. aureus. Gram positive S. aureus was more resistant to tested essential oil than Gram negative E. coli. The diameter of zones of inhibition by the leaf extracts of E. camaldulensis was 10-Conclusions: The results suggested a potential antimicrobial activity of the essential oil of E.camaldulensis, which may find its application in future research for the food and pharmaceutical industry.
