Background and Aim : Acinetobacter baumannii are causes of nosocomial-acquired infections that are related to the biofilms forming talent of this microbe. The immediacy of the drug resistance challenge demanded important treatment, among that was the explore for new antibacterial agents. From nature, that harbors plants, a lot of have been used for therapeutic targets. The goal was to In-vitro antibacterial activity of Eucalyptus extract against clinical isolates of A. baumanni.Methods : A total of ۳۹ clinical isolates of A. baumannii were provided by streak on MacConkey agar, Blood agar, EMB, Gram staining, and different microbiology identification tests. In-vitro antibacterial activities of pathogens were analyzed by typically used microbroth dilution method.Results : Isolates from different departments Shahid Beheshti Hospital were included: ۲۰ (۵۱.۳ %) intensive care units, ۹ (۲۳ %) general surgery, ۷ (۱۸%) emergency, and ۳ (۷.۷%) pediatric. Samples collected of A. baumannii were isolated from patients; ۲۰ (۵۱.۳ %) males and ۱۹ (۴۸.۷ %) females. Outcomes have gotten considering that Eucalyptus extract was active for isolates bacteria with minimal inhibitory concentration ranging from ۱۲۸ to ۲۵۶ mg/ mL.Conclusion : According to important antimicrobail property of aqueous extracts of Eucalyptus on pathogenic microorganism, which supply to the expansion of various types of infectious and nosocomial infection. This extract makes use of natural products.
